The American IronHorse® 2007 Parts and Service Manual has been created for two reasons. First, it will
familiarize the technician with construction of the American IronHorse motorcycles and second, guide them
through approved maintenance and repair procedures. We at American IronHorse are certain that this service
and repair manual will increase your shop turn around time and customer satisfaction.
SERVICE PREPARATION
It is imperative that the proper preparation for service be conducted before beginning a repair procedure.
Ensure that all work areas are clean, this will aid in reducing repair time and will reduce the chance of
misplacing tools and/or parts. Any required tools or materials should be gathered before beginning a repair
procedure.
SERVICE/TECHNICAL BULLETINS
From time to time, service and/or technical bulletins may be issued from American IronHorse. These bulletins
can be the result of an engineering change or serviceability change made at the factory. Please consult service/
technical bulletins before beginning a repair procedure in order to ensure the latest information is being used in
the repair procedure.
REPLACEMENT PARTS
When performing any maintenance or repair procedure use only American IronHosre approved parts. Failure
to use American IronHorse approved parts may result in product malfunction and possible serious injury or
death.

MAINTENANCE 1
REGULARLY SCHEDULED MAINTENANCE:
GENERAL
The following procedures are considered to be regularly scheduled
maintenance. Refer to regularly scheduled maintenance table (Fig. 1) for actual
mileages. Performing the following procedures at specified intervals greatly
reduces excessive wear and tear on motorcycle. The regularly scheduled
maintenance table is a reference tool only. If problems are identified before
actual mileages, they should be addressed immediately. It is the owner’s
responsibility to keep current on regularly scheduled maintenance. In the
event a malfunction occurs, regularly scheduled maintenance records may
be used to determine if owner was at fault by not having motorcycle properly
serviced.

Electrical Section
The electrical section of this manual will address the components of the motorcycle electrical system.
The following pages will give you detailed procedures for removal and replacement of electrical system
components. Also included in this section are specifications on electrical system parts.
Battery: All 2007 American IronHorse® motorcycles use a 12 volt DC, YTX20HL-BS battery. This is a
sealed maintenance free lead acid battery.
Circuit Breaker: All 2007 American IronHorse® motorcycles are circuit protected by a 30 amp Short Stop
circuit breaker.
Starter: American IronHorse® motorcycles use a 1.4kw rated Tech cycle starter.
Stator: As part of the charging system American IronHorse® motorcycles use a 32 amp single phase stator.
Regulator: All 2007 American IronHorse® motorcycles also use a 13.0 to 14.7 volt regulator as part of the
charging system.
Igniter: American IronHorse® 2007 motorcycles use an electronic igniter controlled by the RHC.
RHC: The heart to the entire electrical system is the RHC or Relay Harness Controller. This serves as a power
distribution station, relay station and overall brain of the motorcycle.

Figure 16
CARBURETOR TESTING AND
TUNING
WARNINGS:
•
•
•
Gasoline is extremely flammable and
explosive in certain conditions and toxic
if inhaled. Do not smoke when working
around gasoline. All work should be
performed in a well ventilated area away
from open flame or spark.
Ensure all fuel lines, supply and overflow,
are properly routed and fuel line clamps are
tight. Contact of lines to exhaust pipes or
other hot surfaces could cause lines to melt
and present a significant fire hazard.
Exhaust fumes are highly toxic and
poisonous if breathed. Run motorcycle in
well ventilated area so fumes are allowed to
dissipate.
PRE-START CHECKS:
1. Once carburetor is installed and fuel line secured
to fuel inlet, open fuel petcock and check for
leaks around float bowl gasket and any inline fuel
connections (fuel filter). Correct and clean up any
leaks before starting engine.
2. Check operation of accelerator pump by looking
down the venture of the carburetor while twisting the
throttle rapidly. You should see a steady short stream
of fuel squirting from the ejector nozzle.
2. Start engine and run until slightly warm
(approximately 1-2 minutes), turn rpm adjustment
screw to maintain approximately 1000 RPM during
this warm up period.
3. Turn idle mixture screw clockwise, slowly leaning
mixture until engine starts to die. Next turn screw
counterclockwise, slowly richening mixture until
engine RPM fall off. Mixture adjustment is correct
when screw is positioned about halfway between these
points, or approximately ¼ to ½ turn out from lean
side of the adjustment range.
NOTE: Turning screw out (counterclockwise) makes
idle mixture richer. Turning screw in (clockwise)
makes mixture leaner. For most carburetors, a
correctly adjusted screw will be between 1 ¼ and
1 ¾ turns out from bottom. If idle mixture screw
is turned completely in, engine will not run at idle.
Turning the idle mixture screw in past the bottom,
will damage the carburetor body.
4. After initial idle mixture adjustment, reset engine
idle to approximately 1000 RPM. Lower idle speed
can cause hard starting; poor throttle response, erratic
idle and unnecessary engine wear.
5. After engine has reached normal operating
temperature, repeat steps 3 and 4 then adjust
accelerator pump.
6. Turn accelerator pump travel screw inward or
clockwise until pump contacts actuator arm (stops).
Next turn screw outward or counterclockwise two (2)
turns. Blip throttle and note engine response. Turn
screw outward ¼ turn at a time and recheck throttle
response until engine no longer hesitates.
