Re: Pulse Vibration at High Speed
This may not be of much help and its a bit stupid, but it may pinpoint the problem.
If you still have the old wheels and rims and they are the same size, you could swap them out one at a time to see if one of the new wheels is causing the problem. Or put all of the old ones on first to see if the problem goes away, then put the new ones on one at a time until the problem comes back.
