Front end shudder on my 929
`01 with 31,000 miles on it. Power Pilots with less than 2500 miles on them. I've been getting a some vibration at around 70 mph. Getting shudders at low speed braking. Seems smooth thru the corners. I have the whole front end off because the forks are going to Dan Kyle for him to work his magic. All the bearings seem to be OK. The rotors don't seem to be warped. The tire is very slightly out of round, aprox .030", but seems to be balanced well. I don't do high wheelies, but this tire has gone thru a track day and was shagged pretty good. Ideas?
