Re: G4 and sickbikes shift kit
Hey primusbike, I've run a 4G with shift kit since last summer. I've used 30/48T and 36/48T crank sprockets, switching to 44/44T next weekend. I've also tried 9, 10, 11, and 14T on jackshaft output. Currently using 10, might switch back to 9 next weekend.
I've thought about the belt idea a few times last year, came to the conclusion that it would take more machine work than it's worth. I almost tried it tho, it's really just a pair of cogs and maybe a new 4G output shaft. Thing is, you'd lose freewheel. Some don't like the freewheel, but I do, since I pedal with engine off a lot. Of all 3 chains on the setup, the one I've had the least problems with has been that 12-link from 4G to jackshaft. Therefore, I've left it alone.
