i rarely ride mine anymore, jon. parts are VERY hard to come by. a company called denco had their way with it when it was new. ported, triple squish band heads, their (denco) chambers & vm 36 mikuni's. i have since added a 1 tooth smaller countershaft sprocket, a swingarm off a '74 (1" longer, helps keep the front wheel down), bilstein rear shox & springs, air fork kit, tapered roller bearings in the steering head, needle bearings on the swingarm & a full size (7") headlite bucket for a modern halogen/H-4 bosch headlite. "hold on" might be an understatement, dyno'd at 148 hp, weighs 387 lbs, with a powerband that comes on like a bottlerocket! i have NEVER lost a race to a street legal car, & very **** few to bracket cars or other motorcycles. frame # 304, engine # 284, supposedly the first one sold in fl. no it's NOT for sale................... enough threadjacking, i'll hush now.
