WOBBLING HANDLE BARS WHEN GOING SLOW !!!

Postby kajunmisfitt » Thu Aug 28, 2014 2:10 pm



Hello, Got a problem I am wondering about?
I have this 88' GL1500A (mileage is 06914, or something like that) and here lately, when I would be going slow about 5-20 mph, I let go of the handle bars and they start wobbling very violently,(It is kind of of scary when that happens) .But when I have my hand on the hand grips it is ok. even at 60-80 mph it seems to be riding well. Now I am planning to go on a ride that is 1000 miles round trip this weekend. So I thought I would ask. If It might be something that just need readjusting, like the front wheel, I was told too loosen the front bolts on each side (not much) and take the front wheel and shake it then tighten the bolts again and that should get it to go back into alignment I also looked at the forks seals and their is no extra oil leaking on the forks. I am hoping this is not a bad thing that makes me change my plans to go see my son. Thanks for the help !!!

Heavy weight bikes have long suffered from this problem
The weight on the front wheel is immense and the DE-celebration adds to the issue.
The front wheel can wobble violently if you are not "dampening" the movement with your arms.

Solutions -
A) DO NOT let go with both hands

B) Might be a badly cupped front wheel
C) Loose or worn steering head bearings
D) Worn Springs in forks - low fork oil -
E) Bad swing arm bearings in the rear
F) Badly worn rear tire (yes the rear can shake the front)
G) Under-inflation of the tires (You DO check your tire pressures often right ?)
H) Bad wheel bearings

I would --

Check the tire pressures and ride with 2 hands and go visiting.
Then work on this list to make it better when I return.

MY '96 GL1500 with 130,000 miles on it will do it occasionally when I decelerate with no hands (which I avoid doing)

My Fork Seals are new- My steering head bearings are NEW - My tires are not cupped or worn and are properly inflated.
Swing arm bearings are fine wheel bearings are fine
Basically I can find nothing wrong that would cause this other than the fact that this happens on heavy bikes....

Pay attention - but don't worry... ;)

Thanks Wingsconsin,
This has just started But I do have tires that are getting to the point that I maybe should consider changing them, But I think they can wait the season out. This is a friend bike that allows me to ride it since my GL1100A is not up and running yet. So I will keep an eye on it. I don't go riding around without both hands on the steering. But got in a situation Tuesday and this is what I found. I knew if I let it go it would just end up getting worse. If I had the money I would get the 1100 up and going and ride it up to where my son is. But the 1500 are a lot more comfortable than the 1100, take care

There was another thread about this a while back.. an 1100 I think, but the principles at work are the same. I pretty much agree with everything Wingsconsin wrote. I would also add that GL1500's have a pretty substantial fork brace if I recall correctly. You might also check it for proper positioning and tightness. Heavy loading in the back end can also contribute to front end wobble... having one bag loaded heavily and nothing in the other side can "hurt" handling as well..

Anything loose or out of specs on the front or rear, up to and including loose frame bolting that allows flexing of any structural member of the frame can contribute to the wobble felt in the front end.
I am wrong as often as I am right concerning what is wrong with someone else' motorcycle without having seen the machine in person. Guessing with limited information, as to the source of the trouble, is sketchy at best.

On my 88 (and my previous 89), going slow, the handlebars were rock solid when I let go. I have this habit, as stupid as it may be, when I get off freeway and slow down the off ramp, I will let go of the handlebars just to see if the bike tracks straight for me, and it just glides along. So I would say if it wobbles when it is slow, something is not right.

Neither my 88 or 99 have a stock fork brace. I added a Superbrace to both. It does much to stabilize the front end.

My wing had very bad case of wobbles when first bring home. Underinflated tires that were cupped maybe worst part. 2 new tires and fork brace so bike runs very nice now. Under deceleration I have 2 hands on bars anyways most riders usually do.

Steering bearings in good shape. Forks seem ok but need to replace fork oil. Many things can contribute so just need to start eliminate until good.

I've had this problem show up a few times. Everytime, it was a problem with the tires. The last time, it was a set of Shinko's that only had about 3k miles on them. You get what you pay for, new set of E-3's made the problem go away again.
