I have just started my first cafe racer project with a 1972 CB450 in good condition. Want to relocate the battery under the seat cowl to give a nice clean look. Not great with electrical stuff. How involved is relocating the battery? Will the stock wire harness reach or do I need new wires etc? I do not have turn signals, horn, or use the electric starter. I'm looking for some direction or just a good idea of how much work I'm looking at before I start tearing into things.
