[QUOTE="RossKean, post: 1470848, member: 19880"] I have never bothered. I zip-tie the chain to both of the sprockets on the cams so it cannot possibly drop. I have never had to change an exhaust shim and the intakes can be changed by lifting out just the intake cam and laying it at an angle. The chain from the crank to the exhaust cam never moves and the timing between the cams is fixed by having the chain tied to both. Only thing to watch is that you don't have a tooth slip at the crank (DAMHIK). When looking at parts fiches, I discovered that Yamaha lists THREE different part numbers for valve lifters (shim buckets). Be careful to not switch them around. (I assume they may be slightly different diameter and/or thickness.) I did not realize that until AFTER I did my first valve adjustment. No problems so maybe I was lucky. No idea which is "normal" or if, like shims, they use whatever fits best in the factory. [ATTACH type="full"]8600[/ATTACH] [/QUOTE]
