At highway speed, 70 to 85, i get a slight frotn end wobblle on my rk, checked tire pressure, its at 40, checked rear, its 42. its slight, not violent, but more then there should be, the bars wobble about 3/4 of an inch it seems. any idea??

 

REALLY? NOBODY?

 

I wish I could help. I'm sure someone has some tips.

 

I had the same problem and it was my rear tire...It was not completely bald but was worn enough to get a new one.

 

I had a friend who experienced this a few years ago, except it was any speed over 35 mph. His turned out to be a bad tire.

 

Interesting
how many mile on the bike?

 

What year is your bike? As posted prior, how is the tire as far as tread? How about the neck bearing, has that been checked recently?

 

Wheel out of balance - most likely. Loose steering head bearings? Uneven tire wear or out of round tire. Loose wheel bearings (less likely).

Just some ideas, good luck!

You need to get a svc. manual. I say tire balance/bad tire or fall away adjustment.

 

Check the front and back tire for wear and tire pressure, Check the motor mounts, and make sure the front wheel bearings are in good shape. Had a buddy with the wobble and did everything till he replaced the front wheel bearings.
Have yer neck bearing checked. If you have ape bars look where yer arms are and the airrunning off them.
if you checked all that try cast aluminum wheels if you have spokes.
Try to think what was the last thing you did before the problem started too.
Hope one of these might help.
