Crazy and possibly stupid clutch setup

[NapO]

Hey i was just wondering if this work combo would ok... i have to two speed jackshaft but it's been burning up so im gunnna order a cvt. i was thinking maybe you get a crazy amount of ratios by hooking them up together? i would hook up the cvt to the engine then drive that chain to a jack shaft with sprocket and dual chain clutch then run the two chains to the dual setup and run a sprocket with a chain to the axle? good idea or just too much work for somethin not even worth while? i figure it will give an almost 5:1 or 4:1 ratio?

the clutches will slip and defeat the purpose of the CVT. Just use the CVT, it will give you a good range as is.

yea just use the cvt no need for the extra clutches.

The 2 speed wouldn't burn up if set up correctly.

it normally is pretty good. however i upgraded my enigne to produce more power and i was doubting if the cltuches could take after i took it for it's first run. i do a mixture of off roading and street riding. i think my engine puts out 9 to 10 horses. it's modified gx 160 and plus im running 16 inch tires and it's a heavy frame.

oh i forgot to mention i have 61 tooth sprocket beacuse my i want my max to be at least 80 km/h

just use the CVT.

LOL 80 mk/h with 8hp. I don't think you'll have any acceleration at all.

Why the obsession with top speed? Acceleration and drifting is what's really fun!

Though the CVT we are dealing with is designed to function as a clutch, not all of them are like that. Most scooters are set up with a CVT where the belt is always engaged and there is a clutch on the driven pulley.

i made a bet with my buddy that i would be able to take his mini chopper. the top spped is about 80 km/h. so thats been my target goal u could say. most of the time i'm on long straight aways so it kinda sucks when ur kart an only hit 50 km/h. i do take it off roading to. i had my kart with 81 tooth sprocket and the acceleration was great but it felt like it could soo much better! the two spped jack shaft was pretty good but i wanna see if the cvt is better. usually i could hit about 70 km/h at 0.2 km with a reg clutch or 2 speed (acceleration is better of course) . pick up was slow but once it 4000 rpm, it really takes off. thanks for all ur input guys!

Why? CVT and a clutch? I think it would do worse of a job.

This is actually somewhat necessary on a motorcycle. Ever figured out that with a comet TAV if you let off and slam the throttle just right, the CVT downshifts to neutral and then slams back into gear? The result in a kart is a mad dorifto. Imagine if a motorcycle did that coming out of a corner.
