I looked at the post in the extreme mods section regarding crank runout, and watched the video. This may be a silly question, but could you not measure it from the left side? Seems to me removing the primary chain cover is a lot easier than removing half the exhaust system, pulling apart the top end, and pulling the cam cover as well as the cam plate, cams, chains, oil pump, etc to do it from the cam side. Not only that but you can use a socket on the left side to turn the engine over, which you aren't supposed to do from the right side as I understand. Thanks.
