I was thinking about a possible project to do. I would start with an N600. Take out the engine in the front, and get a CBR 600 motor. Then, remove the dead axle from the back, keeping the leaf springs though, and replace it with some sort of trike axle with a diff. (Same track) then mount the engine in the middle and run the chain to the diff. What are your thoughts? are there any big issues with the idea?
