:?: Hey, burgers,

i need your help with some brainstorming. My wife's 07 650 has developed a right handlebar vibration in the last 1,000 miles this Spring.

It has 33.5 k miles, good, round tires, tight handlebars and bar-end weights, valves that were on the tight side( .001 to .002 over minimum clearance 15K ago), and plugs that should probably be changed now( gas mileage and running- still normal). The scoot has had all the fluids and filters changed regularly as required. What say y'all? Fuel injector sync? Am i overlooking anything else? The vibes become greater at higher speeds and are felt thru the right handlebar and footpeg- now, to the point that her throttle hand is going to sleep! Thank y'all for your input and contributing to a site with lots of camaraderie and little ego.

A texting cager is a BIG bullet with your name on it- steer clear!

God bless,

yammer1hammer

Although I am not familiar with the 650 model..........Did you check the pinch bolts on the front axle.....??? Could be that one of them is not snugged down and causing the problem.. (?)

Unbalanced wheel/tire?
Warped brake disk?
Worn steering-head bearings?
Worn front axle bearings?

Just brainstorming, here. Doesn't seem consistent with it being engine vibration.

Right off hand I can't think of anything that would cause a vibration on only one side. I think the first thing I would do is pull the front wheel and inspect the wheel bearings, especially the right one.

Check the rear tire for de-lamination or loss of balance weights.

I had a section of tire come off on a cross-country trip. It showed up as front-end vibration and front end wheel wobble. It would almost disappear at high speed. I really thought it was the front-end / triple tree.
