Valve Clearance
Refer to
Important Safety Precautions
Excessive valve clearance will cause noise and
eventual engine damage. Little or no clearance will
prevent the valve from closing and cause valve
damage and power loss. Check valve clearance
when the engine is cold at the intervals specified in
the Maintenance Schedule (page 25).
The checking or adjusting of the valve clearance
should be performed while the engine is cold.
The valve clearance will change as engine
temperature rises.
Before inspection, clean the engine thoroughly to
keep dirt from entering the engine.
1. Remove the seat and hang the fuel tank to the
left of the frame (pages 33, 34).
2. Disconnect the breather tube (1) and spark
plug cap (2).
3. Disconnect the ignition coil A connector (3)
and B connector (4).
Remove the ignition coil (5) by removing the
ignition coil bolts (6).
4. Remove the cylinder head cover socket bolts,
rubber seals (7), cylinder head cover packing
(8) and cylinder head cover (9).
