High Speed vibration, can't find what's causing it.

It's always something isn't it? Got to the track yesterday and the starter wasn't working right. Found that the top bolt was coming loose. Burned my wrist on the headers getting it squared away. Then my charger kept tripping the breaker, found a cable connector had broken. 5 minute fix with a propane mini torch and some solder, of course that was at the house, so I had to jury rig it to get through the day. After all of the tinkering the track turned out to be hot and greasy and I kept spinning which cost me the 1st 2 rounds, so I was done for the day. Trying it again on Sunday morning at the TMCCC race. Sorry about your wheels, there is no quick fix for that.
I always have the weights on the inside of the wheel so they can't be seen . I put the silicone heavily around the sides of the weights and a little on top.
