I just got done checking my valves and most of them are in spec except couple of exhaust valves that are about .001" too sloppy and a couple of the intakes which are a little bit tight. First off, how would valves end up too tight unless they came that way from the factory? If anything they should become looser as they wear I would think. On the exhaust valves, do I really need to replace anything because the different size buckets come in .002" increments, so if I replace the ones on the exhaust side, I might end up a little too tight. I have about 57K on the bike.
