Didn't mean to open up a can of worms. Just sayin' what I've seen here.

With that said, devil's advocate time, there aren't any motor restrictions on the XR100's besides CC's. A lightened crank, rod, HC piston, cam, headwork, big carb and full exhaust will make just as massive a difference on an XR100 as it will a XR50 or XR70. There also doesn't seem to be any restrictions on frame, suspension or wheels. There is alot of room for improvement there, too.

I personally own a built CRF50 but haven't had it out in it's latest configuration yet. There are a couple of things I want to do to it while I am in there. When I am done I'll take it down to Stockton and see if I can chase down some XR100's.

Side note: I vote for the full length course (long 90). That's what they ran the AMA Supermoto bikes on there and it was awesome!

I am really, really excited at the prospect of finally riding that track.

P.S. Side note: If you need any info on that GS500E you're prepping for LRRS, let me know. I used to race one and have *alot* of stupid knowledge about those things floating around. Front end swaps, rear shocks, swingarms, etc... They're great little racers. You'll enjoy it!
