Work in progress

The chain isn't slipping, it's jumping the teeth. Once you add torque to that axle it flexes and the chain jumps. Only way to cure this problem is to add a bearing close to the sprocket.

This is the conclusion that i have come to as well, need to move the pillow block from the jackshaft to the axel under the center jackshaft mount, see if it works better.

correct

I added a bearing right next to the sprocket on the axel, used my biggest sprocket and had no jumping of teeth, YES, put on my smaller wheels, to make a smaller gear ratio plus these have ALOT less traction and it seems to work better. too bad it does'nt look as good as with the larger knobbies! here aresome pix of it this way, as well as having a coat of paint!

thanks, it was the look i was going for, love odyssey's, only wish i could find a500cc or so 4 wheeler engine to get reverse and no clutch, did aquire a 500 honda, would give more power, but still no reverse!

Great project! From the first set of pics, it looked like the front-end was going to be way too low and seat angle too upright. With those balloon tires, though, looks like it's right on.
