'92 K75s front end shake...any thoughts?
For some time I've noticed a wobble in the front end that is more pronounced when cornering left than when going straight or cornering right. I've been milking the last out of the front tire for cash flow reasons, and thought that if when I replace the tire it's still there, I'll start looking deeper into the issue.
In the meantime I've replaced the rear tire and shock (got a Hagon shock, like it very much), as these were much more pressing concerns.
Well, now the shake is getting worse. In the past couple days I've noticed that if I take my hands off the handle bars with the throttle closed (sometimes I need two hands to close a zipper on my Roadcrafter, etc.), the bars SHAKE. I mean they shake so badly I've wondered if it would actually devolve into a bona fide tank slapper situation, but haven't wanted to find out, so I'm back on the bars right away.
With my next paycheck I'll have the dough for the front tire, so that's gettting done. If what I've got is a wheel balance issue, then my problem will soon be solved.
What else could it be? Steering head bearings feel good to me..that is, if I pull the bike onto the rear tire while it's on the center stand and move the bars back and forth, I don't feel any deviation in movment. No flat spot or dimple or increased resistance at any portion of the movement from full lock side to side. This doesn't of course mean that the bearings are fine..I could be missing the signal...
The other thought I had was steering damper. I know they have some kind of fluid damper built into the column...perhaps the damper is bad?
Of course, I may have a combinatoin of all of these things going on.
Any thoughts you folks have would be appreciated.
