i bought a knockoff, therein lies the problem. it runs, but after fixing the seals and the leaking carb with gasket maker, i now have to replace the clutch arm and bucking bar. i was debating making a bucking bar and trying to finagle this clutch arm to work but, honestly, if i replace all the fallible parts, the engine must be infallible right? i was hoping to make this, and turn around and sell it for more than i paid to then perpetuate this cycle. however if i sell it, and get a denardis engine, and then figure out how to weld and mount it, i could probably sell a denardis engine bike for considerably more, plus, i would have much more experience in these things. which was the main reason i started on this, to learn about the electric motors handicapped cousin, the internal combustion engine.
