No, not ULW Superbike.

You can run all the Lightweight Classes...

LW Supersport
LW Superbike
LW Grand Prix

Plus...

GT Lights
Thunderbike (Buell pays cash contingency every CCS weekend for experts and ams.)
SuperTwins

If you're 40 or over, you can also run
LW Formula 40

If you want even more track time you can bump up into the Middleweight classes.

Hey Paul

Thanks for all of your help. Henry got all the parts I requested and we got the bike half way sorted out suspension wise.... Penske shock on order, and a fork spring change in order. Otherwise- 5th in Lightweight Superbike, 3rd in Lightweight GP, 2nd in Thunderbike (Thanks for the $$$ Buell!)
Hopefully I'll manage a few 1st place Thunderbike finishes this year! 8)

Congrats on the strong finishes! Look for your Buell contingency check in a few weeks.

Just got my Buell money from Road America last week. Between Buell's F-USA and new CCS contingency program, I've earned $1100 so far this season.

I think you'll notice a nice difference in the stiffer springs. You're running the stock belt drive, right? Gearing's OK so far?

PJ-

Thanks!

Yes, I'm running the stock belt drive... gearing wasn't great for this track (Firebird East) but I made a few mental adjustments to try and smooth things out. My biggest issue was the tendency of the bike to headshake down the straights under wide open throttle, and bottoming out the front suspension under hard braking for a few of the turns. The bike was also a bit heavy on initial turn in, but once turned, was quite stable. I think the Penske shock, heavier springs and revalving the forks will improve the handling considerably. I should have thought about a steering damper before this last race- hard accelleration + short wheelbase= instablity. Next race will be at Las Vegas in Septemeber with a few track days before, so I'm sure we'll have it sorted by then. BTW- the Nissan brake pads supplied by Henry made a world of difference in brake feel and performance...I noticed very little, if any fade in the 3 races I entered the bike in. For reference, the stock pads were good for about 4 laps at a trackday before they raised my concern level.

Congratulations on FUSA/CCS contingency take from Buell.... every dollar helps!

Hmm. Headshake is not normal for the XB. I think that's a byproduct of your weight and the soft stock springs. I raced for a whole season on the XB9 w/o a damper and never felt a headshake (except for the time Dean H. clipped my elbow when he drafted past me on the front straight at Road America, but that's a different story...).

My guess is your weight distribution isn't correct and the rear is sagging more than it should, lightening up the front in the process. When you get the suspension sorted out for your weight, I bet it won't headshake at all. And it will turn in better.

As for me, I did put on a damper after the RA incident. Nice insurance when you need it.

And you're right, the Nissin race kit pads are great. Superb bite and great durability.

Good luck at Las Vegas!

I believe ALL the same classes that an SV can run in:
LW SS, LW SB, GTL, LW GP, LW F-40, Thunderbike, Super Twins and be competative. Of course you can run in any class above yours also.
