Valve Clearance Adjustment on DOHC
I have a motorcycle with DOHC 16-valve 4-cyl engine. The valve clearance needs to be checked/adjusted every 5000 miles according to the owner's manaual. I've done once before, and now I'm doing it for the 2nd time. When I measured, the clearance has become tight again (naturally).
If I set the clearance to the higher side of the spec, what are the disadvantages or problems I might see? For example, the spec on the manual is 0.005" to 0.008". If I set it to 0.009", would there be any running problem or permanent damage to the valve or valve seat on the head?
