Should work in a low hp application ok, may add a little flywheel effect. I just got mine and it is a little heavier than i was expecting. I'm thinking if you mount the clutch on a jackshaft it would allow you to power with any type of engine shaft, short, long, tapered etc., I believe the designers answered somewhere on another forum that it will work ok powered through the sprocket hub. Someone else posed the question if the design allows the clutch to function the same rotating either direction. I'm still waiting on the answer because both Aixro and baby Aixro (XR30) drive on the right side. Even though on board starter is availabe the manual clutch allows bump starting and eliminating the need for e-start, on board or hand held. The one thing I really hated in karting was sitting on the grid and having to be reliant on someone to start you.
