[QUOTE="yamafitter, post: 847120, member: 15141"] When we pulled the cams from BikerGeek's Gen I and checked the shims we were somewhat surpised to find shims that only had one number that did not seem to correspond to the shim's actual thickness when we measured it with Ray's digital micrometer. Even if you had the original shims I believe it is good practise to actually measure the shims rather than trusting the numbers on the shim. I had my digital venier calipers but it did not seem as accurate as Ray's micrometer for this task when we were checking the new shims. If you are going to purchase a micrometer I would recommend that you get a digital unit that has the ability to display both inch and metric measurements. Mitutoyo is a well respected brand name in measurement equipment but Craftsman makes a perfectly acceptable unit. It would make for a nice Christmas present ;) [/QUOTE]
