My 212 is about 10hp+ You know you got power and slippage when you can throttle it and spin that belt at 35.mph I must say that my chain wearing has always been worse than my belt wear. Or at least I can see the chain/ sprocket wear more.Keith, Excelsior's were chain final drive. You have a Orabona build which favored Indian which were always reduction, and final drive chain driven. The power the 212cc torque will always beat up a belt drive. I am looking forward to how this beautiful build shakes out.
