    Jackshaft or no??

    Hey y'all!! I searched and found a lot on cvts and jackshafts but no direct answer to my specific question; with enough gearing, will my clutch handle direct drive without a jackshaft? I'd rather run direct drive utilizing the bike transmission unless I'm gonna smoke a clutch in 10 minutes.

    Do you have more information like what motor you're using, how much you expect the buggy to weigh with you in it, how fast you want to go, your typical riding conditions, etc. That'll give us a better idea of what you're working on. However, usually the issue with not using a jackshaft to get lower gearing is the rear sprocket has to be so large that you lose all your ground clearance.

    Ok one more time: weight is uncertain because the fabrication isn't complete yet. I weigh 230 an I'll be running a Kawasaki 900. Most of the chassis will be 1.5/.120 dom, trailing arm rear an A arm front, 28x10x15 tires, thinking around 13/51 sprockets. 70-80 would be great but a strong 65-75 would be welcome. Baja 500 is the ultimate goal but Texas off-road is the jumping off point. I don't think I'll weigh in at nearly what a kitted out 2 person side by side weighs

    You will need deeper gearing than that. You will also need reverse for a Baja race. And lots of chains........

    No jack shaft. RPM. angle it back so that you can run the longest chain possible. Run the largest sprockets you can. Front and rear.

    Long chain with idler....I'm guessing for heat purposes? According to their little page they have several different ratios so maybe that will take care of the clearance problems presented by hill climbing sprockets
