Check tire pressures on both ends. If they are OK look for odd wear patterns on the front tire. You might be well advised to change the front tire "just because." It is also possible the road has nearly invisible ruts in it caused by heavy trucks.

There should be a sticker on the top of the belt guard showing tire pressures. Some folks feel the stickers are unneeded - for that matter, some feel the belt guard is unneeded - so the sticker might not be there. As I remember the front is supposed to be 29 psi; the rear 33 psi for loads under 200 lbs and 36 psi for heavier. I don't feel like going out in the cold to look at mine. If your tires are not the OEM IRC  tires the pressures might differ.

Mine started that when I had some loose spokes, rear wheel.

Okay thanks guys  here is a little more info, the front tire is in pretty bad shape so I will start there will also check bearings and spokes and pressures, the bike is bobbed with no front fender at all so I guess that could be a part of it too will first replace front tire check spokes and bearings then move on from there will keep posted thanks

Bubba, from one previous post a person who replaced thwe fender noticed an improvement in handling. If you don't intend doing this, please consider a TKAT or Super Brace fork brace.

It's the combo of bad front tire and no front fender. Change the front for something decent, meaning ANYTHING other than a stock IRC. Problem will be about 80% gone.

IRC makes the worst cruiser tires, bar none. Even cheapy Chi-Com Duro and Shinko are better quality. Shinko are currently on sale at Motorcycle Super Store.

I actually prefer the handling of my 98 w/o a front fender, but the grit and gunk on all the roads here is some kind of nasty... had to reinstall it.

Can't hardly argue with what I've read, but I'm not rich , so simple suits me. I rode in the wind three days ago and hated it. I hate March winds. I hated 'em when I worked construction and they tried to blow me off buildings. I hated when they mess up my hair...ok, is this gettin' out of hand? There is a high bridge on the Natchez Trace Parkway over the Tn River. You have a nice, leisurely ride along between pine trees. Then you hit the bridge and you're crossing the center line and leaning over as far as you can to get back. And if your jacket is zipped only halfway, forget it. All at once you're transformed from a rider to a physics experiment. Air your tires up, (Jerry Eberger told me mine were too low since they were Metzeler's, so now 40lbs for me--MAYBE NOT FOR YOU!!!), notice windscreens while riding, both man-made and natural. Coming out from a windscreen can be exciting when you're not ready.
