The first problem. No room for the header, maybe. If I raise the motor on the seat post as high as possible and still leave room I might be able to cut down and make the head pipe turn the corner without having to notch the frame. If I had to notch the frame I'd have a "U" shaped piece welded in to fill the hole in the down pipe but I'm really hoping to avoid that.
Second problem. The throttle cable is too short being it's from a pitbike. With the Chinese throttle assembly would a Chinese cable work on the Dellorto carb?
Third, I'm going to have to get the wider crank set-up. I'm thinking the sick bike parts extended crank shaft should work. The crank looks to be of the smaller "cartridge" type so it should fit.
Hopefully photos upcoming
