Gary was saying his did it at 25-35mph. It's interesting that this is also the most common speed to have the wobbles. That's why I was wondering what would happen if he took the Vetter off, if it's not solidly mounted, and he does say it bobs a bit at high speed, it seems that the fairing and the bike might be having a weird resonance in the front end.

Westco, one thing I forgot to mention in the other posts was to try loosening the lower axle cap nuts & try centering the forks on the wheel. It's a long shot but it's possible you have one side pulled in too close to the wheel & putting a side load on the lower fork sliders.. Maybe try riding it with the forks pulled apart farther then re-try again with the forks pushed together more..

A little good news. I finished up a 1500 mile tour this week and am pleased to report that the jumping problem has disappeared. It must just take some break-in. Idid notice a bad understeer problem, the bike wanted to fall inward when going around 15 mph posted turns. I searched the forum and read that inflating the front to 38 to 40 psi would solve this. I tried 38 psi and it worded great, corrected the steering and didn't cause a reoccurance of the sticktion problem.

Thanks all again, Gary '78 GL1000, now with 37k miles.

The tendency to fall inward during a slow turn is also indicative of head bearings that need some preloading torque. Tightening up the head bearings cured my 1200 of that tendency.

Yes, my 77 bounces a bit when the tire preasure is under 33 or 35, at 38...no more bouncing or wiggling....depending on the situation.

I run the recommended tire pressure - 28 PSI. Never a problem and my bike handles great.

Must be something else wrong.

I got the tip from an old Winger that restores GL1000s by the dozen. It worked on mine....I think Dunlop now recomends a higher preasure.

Maybethe Bridgestones work better on this bike... don't know, but so far so good.

You might be right,......I have a history with Dunlop going back to my first British bike in '74. I'm gon'a stick with'em.


One thing I'm pretty sure about is that every bike, no matter what kind, is at least, slightly different than another.
