Re: First build : Need a bike to build on.
If the engine will fit in the frame, that's a good bike to use. Solve your brake problem with a dual-pull brake handle, so you're pulling both brakes with one handle on the right, and only the clutch on the left. Turn the grip shift around and put it on the left side. You can cut the grip down to size to line up with the grip shift if you like, or not. I didn't cut my grip; I just reach over if I feel like shifting the pedal gear, which I usually do not feel like doing.
