Re: Motorized Bicycle Take a Tip...Leave a Tip
Not sure if this has been suggested yet, but I haven't seen it anywhere:
If the wiring of your engine, lights, etc. has been damaged or covered, label the wires with painter's/masking tape and a sharpie. It will save a lot of guesswork when replacing or refitting them to their proper places.
(Just recommended it to a friend and fellow forum member for his singed wires, and figured some one else may need this method later.)
