CONTROL CABLES

Lubrication
Periodically, disconnect the throttle and clutch cables
at their upper ends. Thoroughly lubricate the cable
pivot points and the inside of clutch cable end adjuster
with a commercially available cable lubricant.
Be certain that the throttle cable has no kinks or other
damage so the throttle slide will return properly.
