PERIODIC MAINTENANCE AND MINOR REPAIR

ble for any consequences caused

EAU00695

by the use of items which have not

Clutch lever free play

been approved by Yamaha.

Since this model is equipped with a hy-
draulic clutch, adjusting the clutch lever
free play is not needed. However, it is
necessary to check the clutch fluid lev-
el and check the hydraulic system for

leakage before each ride. If the clutch
lever free play does become exces-

sive, and shifting becomes rough or
clutch slippage occurs, causing poor

acceleration, there may be air in the

clutch system. If there is air in the hy-

draulic system, have a Yamaha dealer
bleed the system before operating the
motorcycle.
