What a pain in the rear to get to the exhaust valves. When I finally got everything stripped down, they did need some attention. Both exhaust were a very tight .013. I had to really force them to take a .013 feeler gauge. I loosened them up a tad. The right intake was a little loose at .009 which is supposed to .006. The left intake was very tight. I could not force a .006 under it. I didn't have anything smaller to actually check what the clearance was. Reset both intakes to .006. Haven't ridden it but don't expect any noticeable difference. But I am glad I checked them and caught the tight intake one. At least now I know they are set to specs.
