Got a fully functioning dirtbike, just no interest in it. i'd like to build a mini chopper with it, so i'm recycling a majority of the parts. when i look at mini-chopper plans, it seems like you need a clutch or torque converter. i'm pretty sure that my honda is semi-automatic(no clutch, but manual shifting of gears), so i'm wondering if i use the original sprockets, would that suffice? the only use for a clutch is to transfer the engine's power to the drive wheel, so i think it should work.
