loosening the bolt.
21. attach the cable stop with a screw supplied with the
throttle cable, a #8 washer, and a 3/16" screw to the
lever bottom sheet. Tighten with an allen head wrench
(the lever bottom must be in the vertical position).

resistance. Failure to do this operation will not allow
the throttle cable to move the throttle lever properly or
with the full range of motion.
18. Make sure the throttle is in idle position.
19. Route the throttle cable through the 9/16 coated clamp
and install clamp on the lower right portion of the frame
using 1/4 x 3/4" bolt, washer and nut.
