Another Front End Vibration Question

I'll start with the usual apology - I looked but did not see my issue, if it is already addressed in the forum, I apologize.

I have a 2006 K1200GT with about 10,200 miles on the clock. At about 8,800 miles it developed a "wobble" expressed in the front end. End of the day - the rear drive had failed and has been replaced. At about 9,000 I had the tires replaced.

After picking up the bike following the fixing of the rear drive, I still notice some form of movement in the front end. I cannot describe the movement very well because I have not had a chance to ride it much as the brake warning light came on two days after I got the bike back, so the bike is in the shop again. However, the movement feels as if something is "loose," "out of balance," "the tire feels as if it is moving left to right on the front axle waving from left to right." Another way of describing it is the movement is akin to what happens when one is riding in the vortex of spoiled air following a semi. Now this happens even following a van.

This "movement" feeling did not happen prior to the "wobbling" at 8,880 miles. It also did not happen on the other 2006 GT I had. It is noticeable at about 70 mph and above.

Any ideas?

Thanks.

Steve

Have you tried playing around with tire pressures, going up or down a couple psi? That's a cheap and easy thing to check.

Have not changed the tire pressures yet. Did verify them because the tires had just been replaced and the "vibration" was an onset type of event.

Will try your suggestion. Thanks.

May be a long shot, but have you checked your steering dampener?

Your bike is an '06GT and has a completely different front end than the Gen. 1 RS/GT. You might get better traffic and responses if you could get the thread moved into the correct file.

Front End Movement

Not sure where you are riding, but here in So. Cal. we have rain grooved freeways that give bikes with new tires the fits. Its like dancing in the dirt at speed. Wear and tire pressure seems to cure this problem. Hope your fix is simple.

Thanks for the Ideas/Comments

Appears defective ball joints are causing the vibration.

Appreciate the responses.
