Track suspension question after TWS (Texas World Speedway)

So I went to TWS (Texas World Speedway) last Sunday, and had a lot of fun and learned a lot. Instructors were very helpful. Finally got up to speed after almost 10 yrs since last track day. So now I come to my issue. Progressively the front forks got softer and I did notice some fork seal weaping but by the end I'm pretty sure they are completely blown out. I had a zip tie to show travel an even with stiffining them I was almost completely bottomed out. The bike is an '05 636 and previous owner said the forks were resprung and revalved for his weight which is perfect for me. Mechanically I have no problem doing the fork seals but the bike sat for a couple years and I have already had to rebuild a lot. I am wondering if it's a dealer thing or if there is a good race shop here around the Houston area that could go through the forks. Thanks for any help provided.

P1/SCRC in Tomball is top notch for suspension work.

211 S. Persimmon St Suite 100, Tomball, TX.
(281) 255-6004

They support Ty Howard's KTM if that name rings a bell.

The forks are working a lot more on the track than on the street, so the fork oil gets a bit hotter and therefore less viscous, which effectively softens the compression and rebound damping. The older the oil is, the greater the affect this is. So, your compression damping setting may need to be a little higher than on the street, as well as the rebound damping.

First thing I would do would be to change the oil and seals (do it yourself if you can). Set the rebound damping so that when you push on the front end with the brake lever on that the front comes up and just barely starts to back down, too soft and it will pogo up and down (start with full soft to see that).

It's funny that I never see anyone at the track adjust their settings from the cold morning, throughout the day. I check mine in the morning, and later after a couple of sessions, warm oil makes a big difference about, for me about 3-4 clicks or so.

Set the compression damping to about half, go ride and do some hard braking and see what the travel looks like, if it's still bottoming out, then add some more compression damping.

I would also consider going to Patrick at Motorcycles Unlimited, he'll set your ride height/sag for you as well as set the damping up, a few millimeters either way will make a noticeable difference in steering.

If it's bottoming out on the brakes, adding damping isn't going to help. You need more spring preload.

Patrick had setup the bike for the previous owner, so I'm gonna take it over to them. I've rebuilt shocks on a bunch of race cars but never a bike so I guess I'll let them do it and I'll try it myself on my other bike. Gonna do another track day in a couple weeks so I don't want something to happen and ruin the day.

Another vote for P1. I wouldn't take suspension issues anywhere else.

I would go with John or Brandon. They can help you fine tune it at the track.
