Mike has a good point. I bought a Honda CB125 Twin back in the 1980's. A pretty nippy little bike in it's day, for a four stroke. It had 17,000 miles on the clock, and I don't think that the valve clearances had ever been checked. It was running rough on one cylinder, so I thought that I'd check the valve clearances. The rough cylinder was so tight on the exhaust valve, that it couldn't be adjusted enough to correct. It needed a new valve and regrind.
