Important Safety Information
A go-kart can provide many years of service and pleasure, provided you take responsibility for
safety, properly maintain your go-kart and understand the challenges you may encounter while riding.
This go-kart has been designed for younger riders; however, not all youngsters are physically and/
or emotionally prepared to ride. Before parents allow any children to ride this go-kart, we strongly
recommend that both of you read this entire manual so you are fully informed before deciding if your
children are ready to ride. Listed below are some of the most important safety measures one should
take when riding.
! DANGER Always Wear a Helmet
The following statement is a proven fact:
``Helmets significantly reduce the number and severity of head injuries.” Never ride your go-kart
without a helmet. Even a crash at slow speed can result in a fatal head injury if you are not wearing
a helmet. Monster Moto recommends wearing helmets that have been certified for safety by helmet
testing organizations that are independent from the helmet manufacturer. We also recommend that
you wear eye protection, boots, gloves, and other protective gear such as off-road riding pants.
! WARNING Never Carry a Passenger This go-kart has been designed for ONE rider only. There
are no passenger pegs, footrests, handles or seat room for a passenger. Riding with a passenger can
interfere with your ability to operate and/or control the go-kart and may result in serious injury or
death.
! WARNING Ride Off-Road Only
This go-kart has been designed and manufactured for offroad use only. The go-kart is not equipped with lights, turn signals, horn and other features required
to drive on public roads. The tires are not designed for pavement and will make the go-kart unstable
if it is ridden on pavement. If you have to cross a paved road, dismount and walk the go-kart across
the road.
! WARNING
Ride Within Your Limits Never attempt to ride your go-kart in a manner that is
beyond your skill level. It takes time to learn off-road riding skills. Learn to ride your go-kart step by
step. Start by practicing on safe terrain at slow speeds and gradually build your skill level. Instruction
from an experienced rider(s) is highly recommended. Alcohol, drug use, and fatigue will reduce your
ability to make good decisions and ride safely. Monster Moto does not recommend go-kart usage
when influenced by alcohol or drug use or when fatigued.
! WARNING Be Alert for Hazards
The terrain in which you ride can present many hazards.
Always “scan” the terrain ahead of you continually. Watch for unexpected turns, drop-offs, ditches,
rocks and other hazards. Always maintain a speed slow enough to allow you enough time to see and
react to hazards.
! DANGER Do Not Drink and Ride Even one alcoholic drink can impair your ability to ride a
go-kart safely. Each drink afterward will make the impairment worse. Do not drink and ride. Do not
let your friends drink and ride. Remember, throughout the United States, you can be arrested and
charged with Driving Under the Influence (DUI) if you are driving a go-kart while intoxicated.

Important Safety Information
! WARNING Take Time to Learn and Practice Even if you have driven other go-karts, take time
to become familiar with how your Monster Moto go-kart works and handles. Practice in a safe area
until you build your skills and get accustomed to this go-kart’s size and weight.
! WARNING Do Not Operate this Go-Kart at Night Lower visibility at night can greatly reduce
a driver’s judgment. Driving at night is dangerous and will increase the possibility of an accident.
Night is defined as the period of time 30 minutes before sunset to 30 minutes after sunrise.
! DANGER Never Run Your Go-Kart Indoors
The exhaust from the engine contains carbon
monoxide, a poisonous gas which is tasteless & odorless. Carbon monoxide kills.
! WARNING Keep Away from Moving Parts of the Go-Kart
Never place your hands or any
other body part near any moving part of the go-kart. Failure to adhere to this warning may cause
physical harm to your body.
! WARNING Skidding or Sliding
The terrain’s surface can significantly affect turns and your
likelikhood to skid or slide. Skidding in a turn is more likely to occur on slippery surfaces such as snow,
ice, mud and loose gravel. If you skid on ice you may lose all directional control. To avoid skidding on
slippery terrain, keep your speed low and drive carefullly.

Important Safety Information for Parents
As a parent, your child’s safety is your first priority. Riding an off-road go-kart is very fun.
However, bad decisions can result in injury. As a parent, you can prevent
accidents by making informed decisions about if, when and how your child will ride. Always
supervise your child when he/she is riding.
Before you allow your child to ride, you need to decide if he/she is capable of riding. Riding readiness
can vary tremendously from one person to another. Age and size are not the only factors that help
determine one’s riding readiness. There are three other factors that you should also consider before
deciding if your child is ready to ride.
First, consider the physical ability of your child. Your child should be able to steer the go-kart while it
is stationary and in motion. They must be able to reach the kill switch on the cross-bar and comfortably operate the brake and gas pedals. Second, consider your child’s athletic ability. Your child should
be comfortable operating other moving vehicles, like bicycles. You will need to determine if your
child can judge speeds and distances and react with proper coordination between hands and feet.
Any person who does not exhibit good coordination, balance and agility should not ride this go-kart.
Finally, determine your child’s level of mental and emotional maturity. It is imperative that you are
honest with yourself when you ask yourself the following questions: Does your child think through
problems and come to logical conclusions? Does your child obey your rules when they ride their
bicycle? If your child makes bad judgments, takes unwarranted risks and/or does not obey your rules,
they should not ride this go-kart.
If you have decided that your child is ready to ride, please remember the following points and never
let your child ride without a helmet. It is up to you (as a parent) to ensure your child’s safety, even if
they learn to ride from another experienced adult. Never push your child to try things faster than they
are willing or capable of doing. Always supervise your child when they are riding and regularly remind
them about safety rules. As a parent it is your responsibility to be sure that the go-kart is properly
maintained and kept in safe operating condition.
Modifying this go-kart or using parts not manufactured by Monster Moto can make your
go-kart unsafe. Before you consider making any modifications or adding an accessory, please read
the following information carefully.
! WARNING
Improper accessories or modifications can cause a crash in which you can be
seriously hurt or killed. Follow all instructions in this owner’s manual regarding modifications and
accessories.
Monster Moto strongly recommends that you do not remove any original equipment or
modify your go-kart in any way that may alter its design and/or operation. Such a change could
drastically impair the stability, handling, acceleration, and braking capabilities of the go-kart and
cause a crash. We also strongly suggest that you do not make any modifications to the exhaust
system components.

Operating Controls
Engine Stop
The engine stop switch is used to turn off the engine.
When the switch is in the “OFF” position, it will remove the
spark from the ignition system. To start and ride the gokart, push the small red button (top).
This is the “RUN”
position. To shut off the engine, push the large red button
(bottom). This is the “OFF” position.

855-833-6483 OR EMAIL US AT info@monstermoto.com
Operating Controls
Fuel Valve
The two way fuel valve is used to control the flow of fuel
from the gas tank to the carburetor. The valve is located
under the gas tank. Turning the fuel valve to the “ON” position before starting the engine allows fuel to flow from the
tank to the carburetor. Turning the fuel valve to the “OFF”
position after shutting off the engine stops the flow of
fuel from the gas tank to the carburetor. Always keep the
fuel valve in the “OFF” position when you are not using the
go-kart.
Choke Lever
The choke lever is used for starting the engine when it is
cold or when you live in a cold weather climate. It is located
above the air filter on the back of the engine. The choke
lever increases the amount of fuel in the air/fuel mixture
that is delivered to the engine. See the photo to the right.
“Start” - Choke Fully ON “Run” - Choke Fully OFF
Gas Pedal
The gas pedal, painted green and on the right
side of the floor, controls the speed of the engine.
To increase engine speed, push the pedal down.
To reduce engine speed, release the gas pedal.
The gas pedal is spring loaded and will return to the closed
position (engine idle) when you remove your foot.
Brake Pedal
The brake pedal, painted red and on the left side of the
floor, is used to apply the brake to the rear wheel and will
slow or stop the go-kart. When you push on the brake pedal, brake fluid is forced into the brake caliper causing the
caliper to close on the brake disc. The amount of force that
you use when pushing the brake pedal will determine how
much braking power is applied. To release the rear brake,
release the brake pedal.

Operating Controls
Pull Starter Cord
The pull starter cord is used to start the engine and has a
recoil mechanism to retract the cord after the engine has
been started. It is located on the right side of the engine,
directly behind the seat.
Air Filter
The air filter is used to keep dirt and large objects out
of the engine’s air supply. It is located at the rear of the
engine under the air filter cover. Examine the filter before
each ride to be sure it is not dirty and/or full of debris. You may
also use air filter oil (usually in spray cans) to keep the filter
flowing properly.
Spark Plug
The spark plug is used to produce the spark that fires the
engine. You should never touch the spark plug when the
engine is running or you will be shocked. Please refer to the
Basic Maintenance Procedures section of this manual for
detailed instructions on cleaning and replacing a spark
plug.
Brake Mechanism
The MM-K80 go-kart is equipped with a rear hydraulic
disc brake. It provides power to safely bring the go-kart
to a stop. It will also hold the go-kart at a stop if the
engine is running. Refer to the Basic Maintenance
Procedures sec-tion for brake adjustment instructions.

Before Riding
Before you ride, you must be absolutely sure that you and your go-kart are ready to ride. To help you
get prepared, this section of the manual will discuss how to evaluate your riding readiness and how
to perform our recommended pre-ride inspection of your go-kart. If you are a parent, please be sure
you have read the section Important Safety Information for Parents on page 6.
Are You Ready to Ride?
Before you ride your go-kart for the first time, we strongly recommend the following:
1. Completely read this manual.
2. Be sure you have read and understand all of the safety messages and labels.
3. You know how to operate all of the go-kart’s controls.
Before each ride, we also strongly recommend that you:
1. Are in good physical and mental condition.
2. Are free of alcohol and other drugs.
3. Are wearing an approved go-kart helmet with a tight chin strap, eye protection and other
protective clothing.
Protective Gear & Apparel
For your safety, we strongly recommend that you always wear an approved helmet, eye protection,
boots, gloves, long pants and a long sleeved jersey, shirt or jacket whenever you ride. Although complete protection is not possible, wearing the proper gear can reduce the chance of, and severity of,
injuries when you ride.
WARNING
Not wearing a helmet increases the chance of serious injury or death in a crash.
Be sure you always wear your helmet and other protective apparel when you ride.
!
Your helmet is your most important piece of riding gear because it offers the best
protection against head injuries. A good helmet will be approved by a testing
organization independent of the helmet manufacturer and will have a chin strap that can be tightened securely. Open-face helmets offer some protection, but a full-face helmet offers the most
protection. When purchasing a helmet, regardless of style, look for a DOT (Department of Transportation) sticker (USA only). If the helmet has been tested by an independent organization such as the
Snell Institute, you will usually find their logo on a tag inside the padding of the helmet.
! WARNING
Long hair, loose articles of clothing or any other articles worn by the driver
must be completely secured so they remain inside the roll cage of the go-kart. Failure to secure these
items could result in them being caught in the rotating parts of the vehicle or surrounding environment during operation.

Is the Go-kart Ready to Ride?
Before each and every ride you take, it is extremely important that you inspect the go-kart and
make sure any problems you find are corrected. A pre-ride inspection is a must because off-road
riding can be very tough on the go-kart and you do not want to have a breakdown far from help.
! WARNING
Improperly maintaining your go-kart or failing to correct a problem before
riding can cause a crash in which you can be seriously hurt or killed. Always perform a pre-ride
inspection before any ride and correct any problems.
Note to Parents: If a youngster will be performing any of the following pre-ride inspection procedures, it is
your responsibility to provide careful supervision and make sure they are performed correctly.
Pre-ride Inspection
Check the following items before you get on the go-kart:
Tires - Use a tire pressure gauge to check the air pressure (10-15 PSI). Inflate or deflate as needed.
Also check for signs of damage or excessive wear.
Rims - Inspect the rim to be sure it is not bent or damaged.
Leaks - Look under the go-kart for signs of leaking fluid such as engine oil or gasoline.
Engine Oil - Check the level of engine oil and add if needed.
Fuel - Check the level of fuel in the gas tank. Add if needed. Be sure the gas cap is tightened securely.
Drive Chain - Inspect the drive chain condition and slack. Adjust and lubricate if needed. For detailed
instructions on drive chain slack adjustment, see the Basic Maintenance Procedures section of this
manual.
Spark Plug - Check the spark plug for looseness. Tighten if needed. Be sure the cap is fastened to the
spark plug properly.
Nuts & Bolts - Look over entire go-kart for loose nuts and bolts. Tighten if needed.
Check the following items after you get on the go-kart:
Steering Wheel - Be sure go-kart steers freely and the steering wheel is properly secured.
Gas Pedal - Push the gas pedal to be sure it moves easily and freely. Make sure that it returns to the
up position when you release it in all steering positions.
Brakes - Press down on the brake pedal to be sure the brakes are working properly.
Remember, make sure you or your Authorized Monster Moto Service Center correct any problems
before you ride the go-kart.

Basic Operation & Riding
This section of the manual gives basic information on how to begin riding your go-kart. In this
section we will cover how to start and stop the engine, how to use the gas and brake pedal or steps
you need to take when you are finished riding.
To protect your new engine and enjoy optimum performance and service life, be sure you break-in
your go-kart properly. To do this, avoid full throttle starts and rapid acceleration for the first 1-2 hours
of riding.
Safe Riding Precautions
Before riding this go-kart, be sure you have read this entire manual up to this point including the
section titled Important Safety Information & Before Riding.
Even if you have ridden other go-karts in the past, take time to get familiar with the way the
Monster Moto go-kart works and handles. Always practice in a safe area until you have built your skill
level to a point at which you can safely ride the go-kart.
! WARNING
For your safety, avoid starting or operating the go-kart in an enclosed area with
poor ventilation, such as a garage. The go-kart’s exhaust gas contains poisonous carbon monoxide
which can collect rapidly in an enclosed area and result in illness or death.
!
WARNING Your go-kart is not equipped with lights. Do not ride at night.

855-833-6483 OR EMAIL US AT info@monstermoto.com
Braking Technique
This section will cover basic braking technique for your go-kart. To slow or stop the gokart, press down on the brake pedal firmly and smoothly. Gradually increase your braking
pressure as you feel it is needed.
Generally, reduce your speed and complete your braking before you begin a turn. Avoid braking or
quickly releasing the gas pedal while turning. Either of these actions may cause the wheels to slip.
Any wheel slip will reduce your control over the go-kart and could cause a crash.
When riding in wet or rainy conditions, or on loose surfaces such as mud or sand, your ability to
maneuver and stop the go-kart will be reduced. All of your actions should be done in a smooth and
steady manner under these conditions. Rapid acceleration, braking or turning can cause you to lose
control of the go-kart. For your safety, exercise extreme caution when riding under wet, rainy, and/
or muddy conditions.
! DANGER
Use extra precaution when riding in wet or muddy conditions because braking
function may be severely reduced by water or mud on the brake rotors.
Parking & Post-Ride Inspection
When you have finished riding turn the engine stop switch to the “OFF” position. If you are through
riding for the day, turn the fuel valve to the “OFF” position. Always park the go-kart on a flat level
surface.
If you will be storing the go-kart for a long period of time, turn the fuel valve to the “OFF” position while the engine is still running. Open and close the throttle repeatedly until the engine stops
running on its own. This uses up any fuel that still remains in the carburetor. This will help you
avoid carburetor problems that can occur when your go-kart is stored for long periods of time with
gasoline left in the carburetor.

before each ride and follow the maintenance schedule in this section.
Note to Parents: As a parent, it is up to you to make sure the go-kart is properly maintained and kept in
safe operating condition. For youngsters, learning how to take care of a go-kart and perform basic maintenance can be an important part of their riding experience. However, if you allow a youngster to perform
or assist in any maintenance task, such as filling the tank with gasoline, you need to provide close supervision and make sure the task is performed correctly.
! WARNING Failure to properly follow maintenance instructions and precautions can cause you
to be seriously hurt or killed. Always follow the procedures and precautions in this manual.
Important Safety Precautions
Make sure the engine is off before you begin any maintenance or repairs. This will help eliminate the
following hazards:
1. Carbon monoxide poisoning from engine exhaust - Be sure you have adequate ventilation
whenever you operate the engine.
2. Burns from hot go-kart parts - Let the engine and exhaust system cool off before you
touch them.
3. Injury from moving parts - Do not run the engine unless instructed to do so.
Read all instructions before you begin a procedure. Make sure you have all of the tools and skills required. Park the go-kart on level ground and put small blocks of wood in front of, and behind, one or
two of the wheels to keep it from moving. To reduce the chance of a fire or explosion, be careful when
working around gasoline. Use only a non-flammable (high flash point) solvent such as kerosene or
mineral spirits to clean parts. Keep cigarettes, sparks and flames away from all fuel related parts.

Maintenance Schedule
Regular inspection and service is required to keep your go-kart in safe and reliable riding
condition. Below is a maintenance schedule showing when components need to be inspected or serviced. Some items on the list can be performed with basic mechanical skills and hand tools and others are more extensive procedures requiring special training, tools and/or equipment. If you do not
feel capable of performing any of the procedures described in this manual or if you need assistance,
contact your nearest Authorized Service Center. If you decide to do your own maintenance, use only
replacement parts that you have purchased from a Monster Moto dealer or directly from Monster
Moto.
Because this go-kart does not have an odometer, service intervals in the maintenance schedule
are expressed in terms of hours ridden. To avoid missing required maintenance, we suggest you
develop a reliable way to record riding time. Always perform the pre-ride inspection at each
scheduled maintenance interval.
Each item on the maintenance schedule requires some mechanical knowledge. You will find that
some items in the table (marked * and **) may require a higher level of mechanical skill and special
tools. If you do not feel capable of preforming any procedure, please consult your nearest Authorized
Monster Moto Service Center.
Note: Service your go-kart more frequently when you ride in wet or dusty conditions.

Fuel Recommendation
The engine in your go-kart has been designed to run on any gasoline with a pump octane rating of
87 or higher. Most service stations will display the octane rating above each pump. Although it is
not required, Monster Moto recommends using premium gasoline with a 92 octane rating or higher
to ensure maximum performance and reliability. This engine is not designed to work with ethanol
blended fuel.
Use of a lower octane gasoline can cause pre-detonation in the engine. When this occurs, you will
hear a persistent “pinging” or “spark knock” which, if severe, can cause engine damage. It is however no cause for concern if you hear light pinging while the engine is under hard acceleration,
such as climbing up a hill. If pinging occurs under normal load and a steady engine speed, switch
brands of gasoline and be sure you are using the proper octane rating. Use of unleaded fuel is
recommended because it produces fewer engine deposits and extends the life of the engine and
exhaust components.
Never use stale or contaminated gasoline. Never use gasoline that has been mixed with oil. Avoid
getting dust, dirt and water into the fuel tank.
Refueling Procedure
1. Twist the fuel tank cap counter-clockwise and remove the cap from the tank.
2. Using a funnel, add fuel to the tank until the level reaches about 2 inches from the top of the
tank.
3. Twist the fuel cap clockwise until it is securely tight.
WARNING Gasoline is highly flammable and explosive.
You can be burned or seriously injured when handling gasoline.
Always stop the engine before refueling. Only handle gasoline
outdoors. Clean all spills immediately.

12. Check for any oil leaks.
13. Dispose of waste oil in an approved manner.
NOTICE
Always dispose of waste
oil in the proper manner.
Failure to do so is harmful
to the environment and
illegal in most states.
Air Filter
Your air filter is located on the back of the engine in the square plastic case. Proper air filter
maintenance is extremely important for off-road vehicles. Dirty, water-soaked, worn out or defective
air filters will allow dirt, dust, mud and other impurities to pass into the engine. Always replace the air
filter with a filter of the same size and construction.
1. Unclip the clips holding the air cleaner cover to
the housing.
2. Remove the air filter.
3. Wearing rubber gloves and eye protection, clean
filter with a non-flammable solvent like mineral

Basic Maintenance Procedures
Spark Plug Maintenance
A fouled (dirty) spark plug can cause your go-kart to run
poorly and lose performance. Follow the steps below to
inspect, clean and/or replace the spark plug if needed.
1. Clean any dust and dirt from around the spark plug
base.
2. Disconnect the spark plug cap.
3. Remove the spark plug using a 19mm socket or
wrench.
4. Using the photos below for reference, examine the
plug to determine its cleanliness. If the plug is a
normal color, go on to step 6. If the plug is fouled
(dirty), go to step 5.
5. Using a moderate grit sandpaper (220-400), sand
between the center electrode and the side electrode
until all carbon and oil deposits are removed.
If the plug is very dirty, use a spark plug cleaner or move
on to Step 6 to replace your spark plug.
Insulator
Threads
Spark Plug
Gap
Side Electrode
Center Electrode
6. Inspect the spark plug electrodes for wear. The center electrode should have square edges.
The side electrode should not be eroded at all. The insulator should not be cracked or chipped.
Replace the plug with an Autolite 255 spark plug or equivalent if any electrode wear and/or cracks
are present.
7. Check the spark plug gap using a spark plug gapper. Gappers can be purchased at your local auto
parts store. The spark plug gap should be .03in (0.7mm). Always check the gap of a new
spark plug before you install it.
8.Be sure all dirt has been cleaned from the threads. Install the spark plug by
hand. This will prevent stripping and/or cross threading of the threads. Use a 19mm
socket or wrench to securely tighten the spark plug. Do not over or under tighten the spark plug.
! CAUTION
Improperly tightened spark plugs can damage the engine. Too loose, you can burn a
hole in the piston. Too tight, you can damage the threads of the engine.
Normal Spark Plug
(light brown center)
Lean Spark Plug
(white center)
Fouled Spark Plug
(heavy carbon buildup)
Fouled Spark Plug
(heavy oil buildup)
When you inspect the spark plug, generally it will fit into one of the four categories shown above. A normal/clean
spark plug will have a light brown center and displays no wear around the electrodes. A spark plug with a bright
white center indicates a lean condition in the engine. If your plug looks like this, have your go-kart serviced by your
Authorized Monster Moto Service Center immediately. A carbon fouled plug will be completely black with no gloss.
An oil fouled plug will appear a dark shiny brown or shiny black as shown above. An oil fouled plug is caused when
the engine oil seeps by the piston ring and is burned with the fuel. Oil fouled plugs are not uncommon, however, if
your go-kart is consistently oil fouling spark plugs, have it serviced by your Authorized Service Center immediately.

Basic Maintenance Procedures
Bleeding Rear Brakes
If your go-kart will no longer stop safely or the pedal feels “mushy” when applying the brakes, you
will need to bleed the brakes. This section will walk you through the process to properly bleed the
brakes.
1. Locate the bleed valve on the rear brake and
and connect a hose. The hose needs to be
long enough to extend into a small
container partially filled with brake fluid.
Be sure the hose is covered by the fluid
before beginning.
2. Open up the brake fluid reservoir and make
sure it is filled to the “High” mark. Add fluid
if needed to get that level before starting.
Bleed Valve
Only use new DOT 3 brake fluid.
3. Next, have a helper continuously apply
pressure to the brake pedal and keep push-
ing while you slowly open up the bleed
valve. (Turn slowly to the left), keep applying
pressure to the brake pedal during the
whole process. If the brake pedal bottoms
out, release the pedal and push down again.
4. When you feel all the air has been let out of
the system, close the bleed valve and let up
on the brake pedal. Test the brakes again to
see if they are firm. If they are not, repeat
steps 2 & 3 until they are firm when apply-
ing pressure to the brake pedal.
5. Once you have successfully bled the brakes,
remove the drain tube from the bleed
valve and install the protective cover on the
valve.
!
WARNING
Always dispose of any
brake fluid properly at your local hazardous waste facility. DO NOT pour brake fluid down household
drains or into storm drain systems because it is hazardous to people and animals.

Basic Maintenance Procedures
Tire Air Pressure
Properly inflated tires will provide you with the best combination of handling, tread life, and riding
comfort. Generally speaking, underinflated tires will wear unevenly and adversely affect handling.
Underinflated tires are also more likely to fail from being overheated and can cause wheel damage
on rocky terrain. Overinflated tires will cause the go-kart to ride harshly, are prone to failure from
surface hazards and wear unevenly.
! WARNING Using tires that are excessively worn or improperly inflated can cause a crash in
which you can be seriously hurt or killed. Follow all instructions in this owner’s manual regarding tire
inflation and maintenance.
Make sure the valve stem caps are secure. If needed, install a new cap. Always check air pressure
when your tires are cold. If you check the air pressure when the tires are warm, you will get higher
readings. If you let air out of warm tires to match the recommended cold tire pressure, the tires will
be underinflated. The correct cold tire pressures are listed below. If you replace the tire, follow the tire
pressure marked on the sidewall of the tire.
Front Tire (Cold)
Rear Tire (Cold)
10-15 PSI (69-103 kPa)

Basic Maintenance Procedures
Tire Repair
If your tire has been punctured, repair or replace it immediately. You may repair the with a patch, but
it will never be as durable or reliable as a new tire. If you need a replacement tire, purchase genuine
Monster Moto parts or another tire the same size.
! WARNING
Do not attempt to replace the tire if you do not have the proper tools. Using
improper tools can result in damage to the tire or steel rim.
Drive Chain Inspection
The service life of your drive chain will depend on several factors including proper lubrication,
adjustment and riding style. Poor maintenance will cause premature wear and/or damage to the
drive chain and sprockets.
Before you service your drive chain, be sure you are parked on a level surface with the
engine off. It is not necessary to remove or replace the chain to perform recommended
maintenance service.
1. Check the slack in the drive chain midway between the sprockets. Move the chain with your
finger. The vertical measurement should measure between 1/4-1/2 in.
NOTICE
Excessive drive chain slack may allow the drive chain
to damage the engine cases.
Drive Chain
2. Inspect the drive chain for the following: dam-
aged rollers, loose pins, dry or rusted links, kinked or
binding links and excessive wear. Replace the chain if it has damaged rollers, loose pins, or
kinksthatcannot be freed. Lubricate the drive chain if it appears dry or shows signs of rust.
Lubricate any kinked or binding links and work them free. If the chain has damaged rollers, loose
pins or kinks that cannot be freed, follow replace ment procedure outlined later in the manual.
3. You should replace the drive chain once the engine is moved as far back as possible and
slack still remains. This indicates that the chain is worn beyond it’s service limit.
4. Inspect the front and rear sprockets for excessive wear or damage. Refer to the following
illustration to determine sprocket condition. If needed, replace any worn or damaged sprockets.
See your Authorized Monster Moto Service Center for assistance.

Drive Chain Removal, Cleaning & Replacement
If you have been riding in extremely muddy or dusty conditions, the drive chain should be removed
and cleaned before you apply lubricant. Follow the procedure below to remove and clean or replace
the drive chain with a new one.
1. Remove the master link retaining clip (1)
with needle nose pliers. Do not bend or
twist the clip. Remove the master link and
remove the drive chain.
2. Clean the drive chain with a non-flammable
solvent such as kerosene or mineral spirits (1)
not gasoline - and allow it to dry.
3. Inspect the drive chain for possible wear or
damage. Replace the drive chain if it has
any damaged rollers, loose fitting links or
otherwise appears unserviceable.
4. Inspect the sprockets for wear or damage.
Monster Moto recommends that you
replace the sprockets when you install a
new drive chain.
5. Pass the chain over the sprockets and join the ends of the chain with the master link. For ease of
assembly, hold the chain ends against adjacent rear sprocket teeth while inserting the master link.
Install the master link retaining clip so that the closed end of the retaining clip will face the
direction of forward wheel rotation.
6. Lubricate the chain.
The master link is the most critical element of drive chain security. Master links are reusable, as long
as they are in excellent condition. We recommend installing a new master link when you install a
new drive chain. You may find it easier to install a new chain by connecting it to the old chain using a
master link and pulling the old chain to position the new chain on the sprockets.

Resolving the Unexpected
General Guidelines
If you encounter trouble during a ride, the first thing you should do is stop as soon as it is safely possible. Do not continue to ride if you have a flat tire, if you hear an unusual noise or if your go-kart just
does not feel right. If you continue to ride, you may cause more damage to the go-kart and endanger
your own safety.
After you stop, take time to carefully look over your go-kart and identify the problem. Always
consider all of your options before you make a decision. Sometimes a problem can be relatively
minor and can be permanently repaired on the trail provided you have the tools, supplies and skills
needed to do so. In addition, you may be able to make a temporary repair and ride slowly back to
your base where you can get further help and/or supplies.
When a problem appears to be more serious, or you do not have the tools, supplies and skills needed
to make a repair, you will need to choose a safe way to get yourself and the go-kart back to your base.
If you are close enough, you can often push the go-kart back.
Whatever the problem may be, always follow the instructions below:
1. Always put safety first.
2. If the problem is minor and you have the tools, supplies and skills needed to make a temporary
repair, be sure to make permanent repairs as soon as possible.
3. Do not continue riding if you are hurt or if your go-kart is not in safe riding condition.
Recommendations for specific problems follow.
If Your Engine Quits or Will Not Start
If the engine was not making unusual noises before it quit running, and it feels normal when you
operate the pull starter, you can probably rule out a major mechanical problem
First, check the fuel system:
1. Make sure you have fuel in the gas tank and the fuel valve is set to the “ON” position.
2. Turn the fuel valve to the “OFF” position. Disconnect the fuel line from the carburetor and
momentarily turn the fuel valve to “ON”. If fuel does not flow out, there is an obstruction in the fuel
tank, fuel filter or in the fuel line.
3. Reconnect fuel line to carburetor.
! DANGER
Do not use spark, fire or flame near gasoline or fumes. Fire or explosion may result
in severe injury or death. Do not let gas or fumes come in contact with hot engine parts as fire or
explosion may result.
If the fuel system appears to be okay, check the ignition system after any residue gasoline and fumes
have evaporated and surfaces are dry.
1. Check the spark plug cap. Be sure that it is not loose or disconnected.
2. Disconnect the spark plug cap and remove the spark plug. Connect the spark plug to the plug cap
and place the threaded end of the spark plug on a metal part of the engine.
3. Pull the pull start handle while you watch the spark plug. If it sparks, the ignition system is probably
working. If there is no spark, replace the spark plug with a new one. If there is still no spark, there is
a problem with the ignition system.
If you cannot identify or correct a problem, you will have to push your go-kart back to your base or
get some help.

Resolving the Unexpected
If You Have a Flat Tire
How you handle a flat tire on the trail will depend on the severity of damage to the tire and what tools
and supplies you keep with you. If you have a slow leak or a minor puncture, there are two ways you
can try to make a temporary repair:
1. Use an aerosol tire sealer to seal the puncture and inflate the tire. You can do this without
removing the wheel.
2. Use a patch kit to repair the hole in the tire. This requires removal of the wheel and tire.
Do not attempt repair without the proper tools.
If the leak is more severe, or a temporary repair does not hold up, you will need to replace the tire.
If you cannot repair the flat tire on the trail, you will need to push the go-kart back or send for help.
Do not ride back on a flat tire. The go-kart will be hard to handle, and, if the tire comes off the rim, it
can lock up the wheel and cause you to crash.
If You Crash
Personal safety is the first priority after an accident. If you or anyone else has been injured, take plenty
of time to assess the severity of the injuries and determine if it is safe to continue riding. If you cannot
ride safely, send someone for help. Do not ride if you will risk further injury or if your go-kart has been
damaged too severely.
If you decide you are capable of riding safely, carefully inspect the go-kart for damage. Check the
tightness of critical nuts and bolts and operation of control levers, brakes and wheels. If there is minor
damage, or you are not sure about possible damage but decide to ride back to your base, ride slowly
and cautiously.
Sometimes crash damage is hidden or not immediately apparent. Once you get home, inspect your
go-kart thoroughly and fix any problems that you find. Also, be sure to have your Authorized Monster
Moto Service Center inspect the frame after a serious crash.
If a Component Fails
The drive chain, master link, control cables, brake controls and other components can be damaged if
you ride in dense brush or over rocky terrain. As mentioned earlier, making the repair on the trail will
depend on the severity of the damage, tools, supplies, and skills that you have.
1. If the drive chain comes off because the master link clip has been knocked off, you may be able
to repair the chain with a new master link. However, if the chain is broken or causes damage when
it comes off, you may not be able to make a trailside repair.
2. If you damage the throttle cable or some other critical component, the go-kart may be unsafe
to ride. Carefully assess the damage and make any repairs that you can. If you have any doubts, it
is best to be conservative and safe and push your go-kart back to base or have the unit picked up.
