I recently bought a 1987 jag long track 500 f/c or so it says on the side of the tunnels extension. the guy said the person he bought it from put a 440 in it. as i start to do my research i'm finding that many of the parts on it are from a 1991-1993 jag afs LT. I know this because the online diagrams show that the hood and front suspension and the rear suspension motor all from a early 90s jag afs. so im thinking its like 2 sleds pieced together. since this mostly is true they didn't correctly hook everything up. why. my lights don't work. i knew this when i bought it, but figured i would just hook the stuff up. also from a dead standstill pressing the gas, the track just spins. i get off and make sure the skis aren't frozen to the ground. this doesn't happen all the time only the majority of the time. what seems to be the problem. when i sit on it the rear suspension drops to about the half way pt. before it bottoms out. any help suggestions anyone with wiring diagrams or schematics. any performance mods. that i could do. thank everyone. also i have a 1977 exciter 440. 3/4 restored. no pics yet but i'll try t gewt some. what do ya think its worth? andrew
