VALVE CLEARANCE ADJUSTMENT

Excessive valve clearance will cause noise, and
little or no clearance will prevent the valve
from closing and cause valve damage and
power loss. Check valve clearance at the
specified intervals (page 30).
The checking or adjusting of valve clearance
should be performed while the engine is cold.
The clearance will change as the engine
temperature rises.
