slight vibration?

I took her out today for a ride (about 70 miles RT) and I was noticing that on turns at or above 40 MPH I can feel a very slight vibration throught the handlebars. It's so slight I thought it might have been the road surface but I could feel it on a number of different roads. Any ideas?

Thx,
R

Yes, it's my mid-life crisis.

I had the same symptoms not too long ago. My handlebar bolts were loose. All I needed to do was tighten them with a torque wrench to the proper specs (17.5 ft-lbs). While many people don't use a torque wrench and just tighten the bolts up by hand, a recent post revealed that a PO had over tightened these bolts and stripped them.

I'll try that Rick, thanks. I always use the torque wrench on parts where the manual says "tighten to XX foot pounds". The last thing I want to do is screw something up cause I didn't follow directions.

If your front tire is old, make sure that doesn't have a bad spot on it.
Also if you have cold temps and the tire is a little low it may viberate till the tire warms up.

The tire is OEM on my 8 year old bike but it only has 7K on it. I check my tire pressure every time I ride and temps today were in the 70's. I also check my tires before I ride and havent seen any weak spots. MY real concern is that this is the beginning of my front wheel bearings going bad.

I know that anything is possible, but I bought my 93 with 12k on it. I added 20k to it and the have not replaced the bearings, and so far all is good.

Ron, I would look into getting those tires replaced due to the age alone.
Even if it is the wheel bearings, they are fairly cheap and easy replace.

Agreed on both counts. You can get replacement bearings off of eBay for about $20 (front and rear wheels - set o' four). But an 8 yo tire probably should be switched out.

Yeah ditto on the aged tires. I think 5 years is recommended, 3 for sportier, grippier tires. I know 8 is long, the "ingredients" that make it a good tire are pretty much weathered out by now. There are some good threads around here about good, affordable tires, if they're not in the budget.
