Throttle Grip and Cable
If the throttle grip has excessive free play due to cable
stretch or mis-adjustment, there will be a delay in throttle
response. Also, the throttle valve may not open fully at full
throttle. On the other hand, if the throttle grip has no play,
the throttle will be hard to control, and the idle speed will
be erratic. Check the throttle grip play periodically in accor-
dance with the Periodic Maintenance Chart, and adjust the
play if necessary.
The throttle cable routing is shown in Cable, Wire and
Hose Routing in the General Information chapter.
Free Play Inspection
Check the throttle grip free play [B] by lightly turning the
throttle grip [A] back and forth.
