Try internet search for x1,x2,or cat-eye fs509 for your body parts, you may find tank cover or other odd part. Your profile pic look like the bike were trying to reserect now, our only had the fuel tank cover that was salvageable, we've been calling it a cat-eye, it's close either way. We're going naked on this build, I'll do a complete write up in the mid-bike forum in the next day or so..
Nice bike. One of my friends used to have an X1, somebody had painted it almost Mystic. But anyway they are a nice size when you're over 6 foot tall.

Yes when those two wires are connected together it turns off the spark and kills the engine everything else is for novelty my neighbor built his light kit out of all LED lighting for full size sport bikes and then powered it off of one of those cell phone USB battery packs he used the front part of an LED flashlight and epoxying into the headlight housing and it made the headlight actually function and it lights up the road unlike the stock headlight they're just there for novelty
