Been without a motorcycle for a while now looking to get back in. Thinking 1300 VTX so I tested one today. 2008, retro w only 9000 mikes. Everything looked good, started up easily cold. Only thing I noticed it seemed to have a lot of vibration the faster I went. Not a wobble just vibration. Got it up to about 75, so probably really only 65. Is this typical or should I suspect some problem?
