    I know this is probably a shot in the dark posting to this site but I am hoping someone has some knowledge of snowmobiles. I have been trying to help my buddy work on his 1987 yamaha exciter 570. The problem seems to be electrical. The compression was 125psi on the one cylinder and 130psi on the other. I am not sure of the exact specs but it seems to be pretty good. When we were working on it the other day we noticed it had no spark. He recently put a new cdi box on it so I suggested we try a new coil. With the new coil on we have spark. I am not sure if it is enough though cause it still won't start. It doesn't even attempt to start even with starting fluid in it. We tried disconnecting all of the ignition switches and kill-switches to see if they were the problem but they don't seem to be. I am wondering if anyone has any suggestions of what else to look at. I am leaning more towards the stator. It may not be putting out enough juice to give proper spark. We are going to check it with a meter and see. Any other suggestions would be greatly appreciated. I don't want to have to take it to a shop as they want $60 an hour just to look at it.

    The carbs were recently just clean and all the jets cleaned out as well. THe problem started when he blew a running belt and it revved kinda high. I am not to familiar with snowmobiles but have done lots of work on dirt bikes and quads. I am thinking it could be the tors system after reading online. I had a blaster that ran like crap cause of the tors then I bypassed it and it ran great.

    I doubt anyone is following this thread but we have ironed out quite a few of the problems and now it seems that its going to need crankcase seals. We got it running great till it heats up then it dies.
