I had a 1996 ZRT 600 with a clutch kit and a silencer. i was riding in kalkaska MI when on my way back to my aunts house when all of a sudden the sled seemed a bit sluggish. it was only turnin 7200 at WOT i thought that i was fouling a plug. so i tried cleaning it out before the end of the road. but as i approached the end a flame shot out the clutch side and the sled just caught on fire. i was in a panic so i shut it down and got away from it not knowing what was about to happen i was a good ways away from the house still too far to run so i flagged a car down and we called the firemen. they came and put it out but it was too late. the whole sled was cooked. i think it had to do with my needle and seats everytime i stopped with it i had to shut the gas off. i only had 90 miles on it since i had bought it and was going to get new needle and seats the next day. so i think the carb flooded and was shooting gas back into the air box or somethin along the lines of that and that is what started the fire.
