Originally PA 50I, now a Dr. Frankenstein's Creature of sorts. I dremmeled out the nubs in the case to fit a kit, TJT variator, 1/2 inch drill bit to the stock Keihin carb, stiffer clutch springs. DR 70CC kit that has been seized once, and ran lean once causing a sweet explosion in the center of my piston. Smoking the Peoples Pipe.... Its dreamy.
