Put this Super Rat together a few years ago. Husky tank, XR200 seat and Elsie front fender and a reversed Elsie front on the rear. Chopped rear frame loop and a longer 03 Wombat swing arm. MT250 forks and an XL(?) front wheel. Snail pipe and handmade chain guide. And the speed secrets.... A Dirt Squirt cylinder (small ports let my engine guy do mondo porting). I'm sworn to secrecy about the carb info.
I'm Southern Illinois and done a couple of Curtis's races in the past. Great bunch. You St. Louis area? St. Peters was the bomb back in the old daze. I don't post much here, but this board is one of my dailys.
