Hello everybody, I'm lookin to get my motored bikes fix. Issue is, I'm not exactly rolling in dough. My plan, was to get a Harbor Freight 79cc engine and slap that baby on a bike. Then I learned about the jackshaft setup. I spoke with someone and they told me this was neccesary. The problem with this was that its expensive. So now I'm at a loss. I was planning on going with a CNC sprocket hub, so things have been planned out on that front, but I need a solution to a clutch. Help!??
well, what tools do you have? (ie do you have/know a guy with a welder? do you know how to weld? how much $$ we talking etc)
my bike has a 97cc engine and i still use the rag joint, zero problems with it, but your mileage may very.
and yes a jackshaft is really necessary, i tried running mine without one to realize theres NO bottem end. i couldn't even accelerate, i used a jackshaft from a baja warrior.
and if your on a budget, why not just get a CG engine? there under 90$ for a complete kit and they run great! (you just have to break them in correctly, and run 32:1 afterwords)
thats the route i would go personally, yes theirs problems with them, but if you mechanically handy, there no biggie heres what my bike looked like before the 97cc engine, its a standerd CG.
and heres it with the 97cc engine, believe it or not, the CG was faster by 2mph lol
but the 97cc engine is cheaper to run (only get up to 3K on the tach, runs like a diesel lol)
