MAINTENANCE
SPARK ARRESTER CLEANING
Remove the muffler (page 12-2).
Clean the carbon deposits from the spark arrester
screen with a wire brush.
• Be careful to avoid damaging the screen.
Check the spark arrester screen for damage.
Replace the spark arrester if it is damaged.
Install the removed parts in the reverse order of removal.
VALVE CLEARANCE CHECK/
ADJUSTMENT
• Valve clearance inspection and adjustment must be
performed with the engine cold.
Remove the head cover (page 14-2).
Turn the rotor [1] to set the piston at top dead center of
the compression stroke.
• The right end of the projection [2] on the rotor should
align with the corner [3] of the pulser coil bracket,
and both the intake and exhaust valves should
close.
Insert a feeler gauge [1] between the rocker arm [2] and
valve stem [3] to measure the valve clearance.
If adjustment is necessary, proceed as follows:
1. Loosen the lock nut [4] and turn the adjusting screw
to obtain the specified valve clearance.
2. Hold the adjusting screw, and tighten the lock nut to
the specified torque.
3. Recheck the valve clearance, and if necessary,
readjust the valve clearance.
Install the head cover (page 14-2).
The engine and muffler become very hot during
operation, and they remain hot for a while after
operation. Be sure that the engine is cool before
servicing the spark arrester.
