Well, not nessesarly on one wheel, but the front shocks were unloaded pretty good. This happened twice. I was doing some "comparative riding" Very Happy . Third gear at about 75 I felt the front end wobbling kinda like turbalance. When I shifted to fifth, it was gone.

Second time, I felt it around 30-40 going into second all the way through till about 60. I saw a cop and backed off.

Both times I was hard on the throttle. I've checked the tires. I've got 40 in the rear and 32 in the front. No other mods except for the 1300 rearend. I've got the potenza in the logo with 3 oz of dyna beeds in it.

It's not a problem, just kinda scary when the front end gets really light and starts wobllen.


BTW I'm still lop-sided.

could just be harmonic vibrations caused by certain RPM and weight distribution... frotn tire pressure should be up there closer to 38-40 for longer wear and to resit cupping..


how many miles are on the front? Could it be cupped?

With my 1300 final I get more shaking at lower normal cruising speeds because4 of the slightly lower RPMs...

Don't know what all you've done to your bike..
I would check the rear shock bushings, then front tire for cupping (as mentioned), then the windshield if you have one take it off and try the same thing (sounds funny but it was part of my problem), then the steering bearings ( my stock ones were put in at an angle), then the front wheel bearings.
On second thought after the shock bushings check the back tire to make sure the belts are still intact.
Put it up on a stand and run it up the your problem speed to see if it wobbles. Then try the rest. If none of that fixes it you have a problem I know nothing about, and its one that I would get a new bike with.

+1 on what Jerry said. Your bike shouid not do that, darkside or lightside. How the heck are you expected to do wheelies with a shaky back end? I suspect shock bushings.....

+ on the air press. You need to go up, or it will cause a wobble, or can cause a wobble. When you feel it in the rear, its called wollowing,
