That wiring harness is Good Ol' aMerican know-how and I'm sure is easy to service like a tractor. You know I have that extra CB160 tank I might just have to utilize on this project. I'm sure the thing will just fire right up. It's on the list of to-do's for sure. My neighbor just pulled out his "motorcycle in a suitcase" classic.
It's called a Go-Devil (click link) . I'm going to tinker with that this afternoon. This thing is sitting in my garage right now. I have never seen one before so I have to try this out first.
