• Read instructions thoroughly and carefully so all procedures are completely understood before performing any installation steps.

Contact S&S with any questions you may have if any steps are unclear or any abnormalities occur during installation or operation of motorcycle with a S&S part on it.

• Consult an appropriate service manual for your motorcycle for correct disassembly and reassembly procedures for any parts that need to be removed to facilitate installation.

• Use good judgment when performing installation and operating motorcycle. Good judgment begins with a clear head. Don’t let alcohol, drugs or fatigue impair your judgment. Start installation when you are fresh.

• Be sure all federal, state and local laws are obeyed with the installation.

• For optimum performance and safety and to minimize potential damage to carb or other components, use all mounting hardware that is provided and follow all installation instructions.

CAUTION

Do not mix springs, collars or any other components between

S&S Sidewinder spring kits and other S&S spring kits. Extensive engine damage can result and is not covered under warranty.

d. While holding the valve firmly against the seat in the closed position, measure the installed spring height (distance between lower valve spring seating surface and bottom of top collar. See

Figure 1, below, left. Record this measurement in the table below.

e. Measure distance between top collar keepers and top of the valve guide. See Figure 1, Dimension B. Distance must be at least .060" greater than the valve lift of the cam to be used. f. Repeat steps a through e for remaining valves and record all measurements in the table. Be sure to keep track of all parts during assembly to assure they are installed in the same location as they were measured.

WARNING

The safety of the motorcycle rider is dependent of proper installation of this product. If you are not certain of your capabilities or do not have the correct tools for this installation, please consult a professional mechanic. Improper installation of this product could result in injury or death to the rider.

2. Adjust the spring installed heights with the provided shims (if necessary) so that the value of each spring is within +0.010"/-

0.005"of the target installed height listed in the chart below.

Spring Installed Height Measurement and Installation

1. Using the following procedure, determine the spring height and clearance between top collar and valve guide. a. Install the appropriate bottom collar based on which kit you are using.

b. Temporary install the valves.

c. Install the top collars and keepers. Pull the top collar tightly against the keepers to seat the keepers in the collar.

NOTE: If shims are used with kit #900-0594, they must be placed under the

integral lower collar/seal #900-0591.

3. Install valves and springs with the keepers and top collars provided.

Note that the lobe of the S&S keeper must be placed in the top groove of the valve stem when installing kits 900-0594 and 900-

0596

CAUTION

The keepers must be located in the groove closest to the tip of the valve. Any other groove will yield the incorrect installed height and may cause premature valve train failure. S&S is not responsible for incorrect installation. Consult an S&S dealer or

S&S Sales Representative if you have any doubts as to the correct installation of this product. See Figure 2, below

Fig. 1

Dimension A: Installed spring height must be adjusted to dimension in step 2.

Dimension B: Must be .060" greather than lift valve for camshaft to be used.

4. Install the cylinder heads. When the remaining valve train components are assembled, rotate the engine a few times to ensure there is no binding in the valve train.

CAUTION

• Installing springs at height less than recommended dimension will cause rapid spring fatigue resulting in possible engine damage.

• Installing springs at height above recommended dimension will decrease spring tension resulting in possible valve float and engine damage.

• Failure to establish required clearances may cause valve seal failure and other, more extensive engine damage not covered under warranty.

WARNING

Valve spring assembly is under considerable tension when compressed and is potentially dangerous. Wear eye protection and take due caution when checking for coil bind and during installation. After assembly, carefully strike tip of valve stem with plastic hammer to insure that keepers are seated. Direct spring assembly away from face and body during this procedure.
