:mad:I have developed a vibration on acceleration and hwy speeds.
I have a relatively new front and rear tire, at hwy speed, I kill engine, vibration GONE, so I have ruled out tire balance.
I had a little worse vibration so I recently had a shop sync the carbs, I watched him sync with vacuum gauges to near ZERO, ZERO match :confused:!!!! Reduced vibration quite a bit.
The vibration is such that it causes my hands to become slightly NUMB.:mad:
Not sure where to look for the answer to this one.:confused:
Looking to the forum brain trust for what to look for.:D

Hey T.O.M, just a suggestion, have you checked to make sure everything is tight since you've recently replaced both tires? On my previously owned 650, I also had a vibration on acceleration and hwy speeds. I retightened everything on the front and rear suspension and the vibration went away. Hope this helps. Let us know what it turns out to be. I always say try the simple things first, lol.

Had a mechanic look at the bike re vibration!
Ran a compression test, front 120, rear 70 NOT GOOD!!!
Has anyone had a "VALVE JOB DONE" ON A 650?
If so approximately what was the cost?
Was it done by private shop or dealer?
