Hello all i have a 1982 Kawasaki GPZ 750 that has a wobbling problem at high speeds and also when i go around a bend in the highway like a exit ramp if im not carefull i get the same problem i have to slow down a bit to getit back in control. I have new tires on the bike and they are balanced also. ANy sugestions is appreciated.

Thanks,

If you know that the tires and rims are in good condition, how is the suspension and the steering head bearings? Did you go with the same/stock size of tires on the ride?

 

As the old joke goes.......if it wobbles at high speed, don't do high speeds.

Seriously, as Dragone#19 said, check the suspension and steering bearings. Also, just because you have new tires and theywere balanced doesn't mean they are "right". Bad tires (chord separation and such) won't necessarily show up on a balance. Could be a bad balance job, too. Also, make sure everything is tight. A loose axel/nut could be to blame.

Just some thoughts, hope it is an easy fix.

...And check the alignment on your tires.
If you are running theoriginal shocks and fork springs/fluid, I guarantee it will wobble. [sm=jawdrop.gif]

 

Thanks to all the replys, i had the new tires put on last year they are the same size as the old ones, and i had the same problem before i replaced the tires. The front fork oil was replaced along with the o-rings about 2 years ago. but i had this problem for quite some years now i have not addressed it much because i thought it might be the tires since they were old and a bit worn,and i dont get to realy ride as much as i would like to. Thank you again to all the replys.

Personnally, two years without changing the fluid is a long time. If the fluid level is off, that causes issues as well.
