I picked a 1981 gs1000gl about a month ago, in exchange for some labor. Since I was now the new owner, I went thru the bike to make sure it was road worthy. Everything was up to snuff until three days ago.

I made a left U turn and the bike wanted to lay down on me. After I got pointed in the direction I wanted to go, I visually checked the tires to make sure I didn't have a flat. Riding back home, everything was fine until I turned left into my driveway. It flopped over so bad, I had to put my foot down to keep it from falling over. In the garage, I found what I thought was the culprit. The throttle cable was binding up on the neck of the frame. Obviously, I re routed it to eliminate the bind.

Riding back home today, I turned into the driveway and experienced the same thing, only not as sever.

Here's what I have done.

Proper air pressure in tires
changed the fork oil to specs, using 10/30 wt.
checked the fall off
moved the forks back and forth to check neck bearings. It's tight like it should be.
slowly moved the handlebars lock to lock to check for bindings. Nothing.

I haven't tore down the front end yet and visually inspected the bearings. But is it possible that the neck bearings are too tight? At the moment I'm really stumped.

That's what I thought, Dods. I really am at a loss here. A friend of mine suggested I check the wheel bearings. They might be loose. Unlikely, but I'll check them tomorrow.

In the mean time, I'm having a Bourbon and Water. :grin:

Since the bars turn lock to lock free and smooth, my first thought was wheel bearings too (front OR rear). But it could also be rear swingarm bearings. Also loose spokes.

I wonder what the front end feels like with the front wheel raised off the ground. Is it "notchy"? Damaged bearings?

Change your timing belts!

There are no timing belts on a Suzuki GS1000GL. That would be a Honda GL1000 or Goldwing.

What you say about getting the front end up is a good idea. It should have a center stand that will help in this. Put it on the stand and have someone sit on the passenger seat or if you have a scissor jack raise the front off the ground by jacking it up under the header, just pad it and be careful. Grab the tire and see it the is a lateral movement in the wheel bearings. Also grab the wheel and push and pull front to back, to see if there is any play in the steering bearings, but I don't know why that would have any effect on left turns only. When you turn the front end lock to lock, is it equal distance? Could you have a broken off or bent steering stop?

jag13 wins a new plastic Spork with it's own personal holder! A friend of mine came over and we both went thru the bike yesterday. I did check it just after I got the bike, but the bearings were loose on the swing arm. Today, as I sat on my antique upside down milk crate, I was going thru the steps I needed to take for the removal of the swing arm. Then I had a thought. Bearings don't just die. They will give you a warning that they need attention. And in less than a month, with very little riding, they suddenly went bad? No. No way.

I pulled the dust covers off both sides of the swing arm, and loosened the large jam nuts. Both had worked loose somehow, and the smaller nut with the shank that presses against the bearing, spun easily. With an Allen wrench, I seated the small nut and backed it off about a 1/4 turn, and tightened the jam nuts down. Problem solved! I have no idea what the specs are to set up the bearings, and I do need a little bit more tweaking to get it right, but at least I can ride it now without worrying about falling over.

Thanks jag!:grin:
