Default Re: anyone having problems with jackshaft front bearing?

I have been using mine with the regular freewheel. I did'nt have any issues except that there's a very slight wobble. Anyways, I used to experience the bottom bracket getting loose. Use a good thread locker on the bottom brackets. Also make sure the drive chain from the jackshaft is not too tight. Only issue I had is that angled aluminum bar broke in half. I just replaced it with a steel one. So far no issues with the front freewheel. besides I have a spare...

You are using that aluminum angled bar? It's an optional installation, but highly recommended. It helps stablizes the engine and keep it in alignment when torque is applied.
Regardless if it's left or wrong, the opposite is always right.
