VALVE CLEARANCE

Refer to the Safety Precautions on Page 34.
Should be serviced by your Honda dealer,
unless the owner has the proper tools and
service data and is mechanically qualified.
Refer to the Official Honda Shop Manual.
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 the valve clearance at the specified
intervals when the engine is in cold condition.
The checking or adjusting of the clearance
should be performed while the engine is cold.
The clearance will change as the engine
temperature rises.
The adjustment must be made when the
piston is at the top of the compression
stroke when both the intake and exhaust
valves are closed.
