Throttle Operation
Operate the throttle grip to see if the throttle
cable is going smoothly. If the throttle cable is
deteriorated, twisted or damaged, replace it
with new part.
If the throttle cable doesn't operate smoothly,
apply some lubrication oil onto it.
Measure the free play of the throttle grip,
through the inner side flange of it.
Free play：2~6 mm
Please loosen the lock nut and adjust the
throttle cable nut to reach the normal free
play.
PCV System
Unplug the drain pipe, and leak the
deposit off. Drain the pipe every 2,000
km.
Caution
Under rainy or full- throttle situation, the
maintenance period should be shortened.
You can check the deposit amount
through the transparent pipe.
