Okay I have a older Skidoo 377 f/c that I want to build a kart around. I plan on using as much of the snowmobile drivetrain as possible. and was just wondering what the best way to do this would be? Would 1" thick tube steel be thick enough for a frame? I am new to karts but am pretty big into sleds so I do know a little about how stuff works. any input is needed. Pictures of sled engines in go kart would help as well. thanks. Grant.
