Valve clearance

The valves are an important engine
component, and since valve clearance
changes with use, they must be
checked and adjusted at the intervals
speci ed in the periodic maintenance
chart. Unadjusted valves can result in
improper air-fuel
noise, and eventually engine damage.
To prevent this from occurring, have
your Yamaha dealer check and adjust
the valve clearance at regular intervals.
TIP
This service must be performed when
the engine is cold.
