I wasn't originally going to motor swap it, but then I had a spare Derbi engine that looked like it would fit in well.
I cut some custom engine mount plates and got to work. originally I was going to use a flat reed, but then a start 5 fell into my lap. I made the mount go thru the swingarm mount so that way it would stay aligned. Aligning everything was difficult, but I got it pretty straight. After removing all the material of the frame I needed to add some new down tube supports.
I used tubing in my vice and a big tube over it and bent it slowly one cm at a time.
After I got everything welded up, I sanded it, primed it, and painted it with a 2 part urethane paint. After paint, I then started cleaning up all the parts and putting it back together.
I got this awesome pipe... But it doesn't fit so I guess I gotta hack it up.
I also picked up new plastics and took a test photo before I got eh frame painted.
