[QUOTE="Geezer, post: 1137584, member: 436"] I did the same thing on my Gen 1 a few years back. I simply retimed the cam and all was well. The timing marks on the cams allow Yamaha to use the same part for both intake and exhaust, so if you get one wrong then the two cams will work exactly at the same time and both intake and exhaust will open together. The engine won't run but the valves won't touch the pistons. [/QUOTE]
