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.
