Valve Inspection

Refer to Safety Precautions on page 113.
Valve clearance should be:
intake: 0.15 mm (0.006 in)
exhaust: 0.23 mm (0.009 in)
Excessive clearance will cause noise. Insufficient clearance will cause
loss of power and possibly damage the valves.
For those who are mechanically proficient and have the proper tools,
instructions on adjusting valve clearances are given in the official
Honda Shop Manual. Otherwise, the valves should be adjusted by
your dealer.
