Re: Where's my fuse box?
If it was an AMA racing bike it is probably all custom wiring. I'm not sure if HRC made special wiring harness back then or not. I'd pull that harness out and buy one off ebay that is complete and un-hacked. Really to wire up a bike all you have to know on those bikes is the wiring diagram and someone has posted a 93-95 wiring diagram on this website. Just follow the wiring diagram.
Yep, you can not eliminate that starter relay from the electrical system or the fuse. If you can find a wiring guru he/she can make a custom harness for what you want using your stock electrical components.
If you are going complete street fighter naked, you can stash most of the electrical stuff under the driver seat or under the passenger seat.
