hi
is it turning over but with no spark ? have you checked the earths around the coil , changed to a new spark plug , checked the multyplug that comes out of the left engine case under the seat . are your nuetral / reverse lights functioning ok? keep us updated thanks

ya i checked the grounds and put a new plug in.. the ppl that had it before did something to the wiring and bypassed all of the switches and took the lights off i noticed there is 2 boxes on the front of the 4 wheeler... theres a small box (i guess cdi?) and theres a bigger one i think one of them are out but im not sure what makes it fire. we got the 4 wheeler and the rearend was out, i put one on it (with no chain) and started it up and let it run for awhile and it was runnin good so i killed it, put a chain on it and it wouldnt start back up (no fire)

the box on the left is a reverse interlock box and on the right is the CDI module.
