I am totally stumped on what to do with my 98 xc. A week ago when i was on a ride i was on my way home and it started a bad bog then it wouldnt really rev past about 6 grand, just sputters and won't. So i thought it seemed like it was freezing up and put it in the shed with the heat on and put some alcohol in for the next ride. It seemed like it helped for a while but as soon as we went for a good ride again it would'nt rev up again and was doing the same thing. I put it back on the trailer and when i tried to start it again it wouldn't start, no spark. I got that fixed as i had ajusted the carb cables and the needle was sitting on the bottom too much and there was some slack in the cable therefore the throttle thing killed it. I thought maybe that is why it wasnt reving up because it wasnt getting a good spark but it still is doing it. I've unplugeg the kill and tried that and even unpluged the block at the motor and still the problem is there. My brother has the same sled and i stole his cdi and tried it and also the carbs and tried them and the reeds look like there fine and i just am stumped. Does anyone have any ideas and know where i can some schematics on the electrical so i can start testing the coil/stator. Any ideas are much appreciated, thanks in advance.
