Visually check for contact of shift lever to shifter opening in the front fender. Ensure shift linkage or shift lever is not contacting the frame or exhaust components.

Tighten shift linkage rod end jam nuts properly after adjustment. You should be able to rotate the linkage rod between 1/8 and 1/4 turn after both jam nuts are tight.

The transmission shift linkage should be periodically inspected for wear and parts replaced as required to remove excess play from shift linkage.


1. Inspect shift linkage tie rod ends, clevis and pivot bushings and replace if worn or damaged.
2. Place gear selector in neutral.
3. Loosen rod end adjuster jam nuts (A) on both ends of linkage rod. NOTE: The jam nut closest to the knurled end is Left Hand thread.
4. Turn linkage rod (A) to shorten or lengthen rod until the shift lever is centered on hole in the fender.
5. Hold rod end parallel to mounting surface and tighten jam nuts securely.

If the choke knob does not stay out when pulled, adjust the choke tension by tightening the tensioner located under the rubber boot between the choke knob and nut. Firmly grasp the rubber boot and tighten until the choke slides freely but stays out when pulled. Verify free play of 1/16--3/16” (1.6--4.76 mm) and smooth operation of choke cable. If smooth choke operation is not obtainable, inspect choke cable for kinks or sharp bends in routing.

4. Set idle speed to 1200 RPM. Always check throttle cable freeplay after adjusting idle speed and adjust if necessary.
5. Slowly turn mixture screw clockwise using the pilot screw wrench until engine begins to miss.
6. Slowly turn mixture screw counterclockwise until idle speed increases to maximum RPM. Continue turning counterclockwise until idle RPM begins to drop.
7. Center the pilot screw between the points in Step 5 and 6.
8. Re adjust idle speed if not within specification.
