Default Re: jack shaft on a cruiser

After thinking about it, I could be wrong Pablo. I was thinking that it is spinning any time the motor, No wait, I am correct to say that the crank is always spinning if you are running the motor.
Without the jackshaft kit, the engine drives the rear wheel and the crank only spins if you peddle. It's also correct to say that the freewheel is also always spinning.
I also plan to put a grease nipple in my rear rim. I find that once a month I have to tighten up my bearings as I get too much play.The grease is always gone as well. I'm at that point again, if I put on my brakes, I can see the brake pad move the rim over to the side. These wheels were not made to go 40 miles an hour for hours at a time.
