[QUOTE="Windjammer, post: 15252, member: 128"] First of all, I never used a Motion Pro, so I can't comment on its accuracy. I do want to clarify that the scale is important. The scale needs to be fine enough to allow you to properly see imbalance. I had one set of gauges that had a very coarse scale reading. The TB's looked balanced on them, but the Morgan, which has a finer scale, revealed that they really weren't balanced, and the results obseved on the Morgan were backed up by the way the bike ran. Finer scale = easier to see and achieve accurate balance. It was also helpful to me to use the correct idle speed and air screw adjustment on cylinder #3, so that the initial number achieved for the baseline setting on #3 was correct. I agree that this does not affect overall balance, but having the correct baseline on #3 made it easier to get the other TB's adjusted without bottoming out adjustments, etc. FWIW [/QUOTE]
