Front tire wabble

Postby bjcrit » Wed Aug 01, 2012 11:54 am



I have an 81 GL 1100 std, with the front tire as a Shinko Tourmaster.
The problem I have had since I had the tire installed is at approx. 25 - 40 mph, I often, (not always) get a tire wabble. If I slow down or speed up it goes away.
I have checked the bearings and everything seems "tight".
The tire has a what I will call (for lack of a better term) an off set, back and fourth center groove pattern. I wondered if that is what might be causing the wabble, but everything I read says that the off set pattern is supposed to help set a straight line and not wabble or in other words track better.
Any suggestions?

I am having the same problem. It seems to be common according to other boards. Everyone seems to agree that checking air pressure in tires and suspension, and making sure everything is torqued to specs. I'll let you know what I find out.

Did you use Dynabeads? I have not had an issue since I went with them.

I have not tried the Dynabeads, but I would like to, didn't know if they realy work until recetly.
The problem started just after the tire was instaled, so I thought it was probably the tire as it is one of the more "inexpensive" tires out there.
Anybody out there have the Shinko tires? How are they for you?
Thanks for the help/advice.

On a friends advise I tried the Shinkos on my '76 GL1000 and have had a great experience with them. I will shortly be putting them on my Interstate. They have exceeded my expectations.

My 1980 GL1100 does the same thing with Dunlop Elite. Not sure what is causing it. New wheel bearings and brakes, no improvement. As long as I keep my hands where they belong, it's not a problem

To "binder 49";
Do your Dunlops have a straight or "off set" (?) center groove in the front tire?

Can any of you give me advice on front tires?
Does the center groove need to be straight or "off set" for more control going over rain groove in the road or grated bridges?
Thanks

I have Shinko's also.. Really nice tire. I had a mild wobble at about 30mph, replaced the Dunlops with Shinkos, and 83-1100i rides so much better..

If you still have the wobble at 25 to 40 mph you might check the rear tire. Exact same symptoms on my 1500 turned out to be an out of balance rear tire which caused it to wear uneven around circumference. A lot of wobble problems are caused by the rear and not the front.

I had a weave on my GL1100 that started at around 55 mph and got worse as my speed went up. It started when I put fresh tires on the bike. After unsuccessful troubleshooting, I eventually found the problem was incorrectly installed and torqued rear swingarm pivot pins (left was on the right side, right was on the left side). It was allowing the swingarm excessive lateral free play. With the old flattened rear tire, the tire provided enough castering effect to keep the swingarm in line. With the new, rounded tire, the castering effect was lessened, the swingarm started swinging, and the result was a weave. Once I fixed and torqued the pivot pins, the weave went away.
