I bought a 86 xr 600r with a bad top end. Dude ran it low on oil, and the top went out. The guy I got it from gave me a complete new( used ) motor. He said it was outta a xl model and it has a lighting coil in the stator in case i want to put a headlight on it. Now from what im reading the ignition system is an AC system, and the lights will be DC . Am I correct so far? I swapped the 5 wire for the 2 wire just to fire the motor because it plugged right into the xr harness. But like i said a headlight is gonna be kinda nice. Anywho...theres 2 wires ,obviously, required for the bike to run. A smaller green/red tracer that looks like it goes to a gauge sender. That leaves 2 wires . Is this simply a DC + and a DC - thats commin off there? Im kinda a new bike mechanic so try not to gimme too much crap. Another thing is I was gonna use a couple of those micro cree LED lights. Am I gonna run into any prob? Are they vastly different than incadescents? Any input will be appreciated, unless its criticizing my punctuation, spelling ,or grammar. I know its terrible, gimme a break!
