It's all about the torque. I guess that's possible. But where to get the gears? Also, that would mean taking the tranny apart, which is slightly scarier and requires special tools, I think.

A straight swap should theoretically only take a couple of hours:

- remove starter
- detatch steel lower rad tube bolted on top
- disconnect clutch cable, reverse switch wires, speedo cable
- remove axles
- support engine
- unbolt & remove tranny
