My KX500 at "Track Day"

I understand completely. That is why I purchased a steering stabilizer. I could keep the forks high in the tripple tree so I could attack the corners and use the stabilizer for the streights. Usally never suffered from that though because I always wheelied in the streights. Before the drag days. Now, I just stick to a minibike (250cc 2stroke) on the track and trails.

Polar,
  Good story! Sounds like you had a blast!  I agree with Arigato I don't think the K5 should headshake that much. On mine it is so rare.  Possibly there is some more dialing you can do. I know too much fork compression will do it. Cam.

I had something like that when I took my k5 out for the first time. How are your handlebars? Are they adjusted up so more weight is on the front? I pulled my bars down and it took care of the problem. Paul.

I'm a little confused as to your  description of  "too much fork compression", but my 500 was headshaking while hard on the gas down the straights. Near the end of the straight (so the front tire is lightly loaded in the dirt), applying front brake (heavily loading the front tire), the headshake would deminish.

My '97 KX250 had the same issue, only not as bad. I was able to dial out most all of the headshake by front fork ride height.

I called Tucker Rocky, and my goddam GPR steering damper is on backorder, as they are brand new items from GPR. I plan on posting up lots of pics when I install it. The GPR units look sweet (and my dealer cost for one is only $300)

Paul, my handlebars are as far foreward, and "high" as will reasonable allow. older KX's are well know for too cramped a handelbar position stock.

KXcam22:
Polar,
    I meant that there might be too much fork compression dialed in on the suspension clicker (bottom of the fork).   Sometimes when on the gas and the front end is light, it will cause the front tire to ricochet side to side off small bumps instead of absorbing them.  Cam.
