Finally got the 1970 Rupp Scrambler out of the basement for a maiden test run. It has a H35 on it. (Non Stock Wheels etc) Running 41 chain. Ratios go: 10 tooth clutch to 14 tooth jackshaft in, 12 jackshaft out to 52 tooth rear sprocket. Despite the engine not running smoothly (I don't have a 20 degree manifold) and possibly the fact that the clutch is maybe fairly worn out, maybe not. The bike barely moved. Am I way off in my ratio's?
Thanks, here is a video:
