sled clutch on solid axle?

[gixxerkart]

can i run the secondary clutch from my sled motor on the drive axle? someone here said no, but i didn't a clear explaination.
seems as if you'd need the jackshaft to pick up some acceleration.

 

[gixxerkart]

oh ya, would the secondary still activate if ran on the axle? these things are momentum-activated right?

The problem is that you will not have an appropriate gear ratio by skipping the jackshaft. Without it, you'll be geared way too high, stressing out the CVT. Takeoffs will suck, and probably burn the belt in short order.

good to know. could i get away with only one jackshaft, and just ultilize the one that is on the secondary clutch now and change the number of gear teeth? i'm using the yerfdog 4209 60 tooth sprocket now. i'd like max speed to be around 45-50mph. what size sprocket should i get for that?

I doubt you would even move with the secondary directly on the axle. Ratio is far too high.

You will probably have to do a double jackshaft in order to get the right gear reduction. Need to know your tire size to suggest a ratio.

oh. its the standard turf savers that came on yerfdog 4209. 8" rim i believe. i can check it. or you can tell me how to calculate it. teach me to fish, don't feed me.

Fine. STARVE! Kidding. I would think a single jackshaft will do. To do the speed calcs, we also need max engine RPM, and the high ratio of the CVT.
