I am trying to solve the age-old problem of torque vs. speed. I have a large go kart that I have a jack shaft on. My thought was to connect one motor with built-in gear reduction to the shaft with a freewheel sprocket on the shaft and a second, faster motor to the shaft as well. When I start...

I built a jackshaft and that helped quite a bit. The 10mm shaft on the motor stripped out because the rotation of the motor loosened the nut and locking washer. It was an odd nut, so I could not find a nylock. I had the sprocket welded on. I was wondering if I could add a second motor to the...

I am going to try a jack shaft before replacing the motor. That seems like a logical first step and it may be necessary even with a geared motor in the future to optimize torque vs. speed.

Thank you SwampDonkey for getting this tread started and for the help so far. I have a large go kart/dune buggy. It is most similar to a Yerf Dog 30032. Here are the relevant specs and parts I have: 1. Approximate weight: 300 lbs, plus 200 lbs in passengers. 2. 18 in tires 3. 72 tooth rear...
