Too much torque

[Grimace]

Plus too much bite on the tires =

Busted 3/4 inch jackshaft. Time to make a 3rd bearing support.

groan.

Oh yeah, all of the dents and dings are new. I had the throttle on the wood when it broke.

Funny, this reminds me of drag racing. Build, race, break, build again better.

No kidding bud!!

Wow! Fair effort there.

We can rebuild it. Faster. Stronger. Only I hope you don't spend 6 million dollars....

when you rebuild, you can consider adjusting the driven pulley to be a bit softer.

How is that chinese driven clutch working so far?

Clutch is working fine. Goes from low gear to high and back to low just fine. Would recommend it to anyone. Just need a third bearing support outside of the drive sprocket off of the jackshaft to take the torsional load.

With my jackshaft, I kinda over achieved and used a 1" axle i had laying around. Kinda too much but its not gonna break. With another bearing, it will give you support, yes, but it might still break in the future. IMO, I would get some steel tubing, and run a sleeve over your jackshaft to keep it from flexing. A better thing to use is a shaft stiffener. they work great, just slide them in between your sprockets and bearing and tighten them down. Both of these ideas will keep your shaft from flexing/twisting.
