Alrighty, I have decided to try my hand at working on snowmobiles. I found a guy that had a 1985 Polaris Indy SS 440, he was selling it for $50. He said it lost compression in one cylinder when he was riding it last year. New piston kit with, of course, a carb cleaning, is all it needs to get it running he said. I brought it home after a two and a half hour round trip. I tried a compression test and I got, literally, zero compression. That can't be right I thought, so I tried again, nothing. I put my thumb over the spark plug hole but still nothing. I shine a flashlight down that cylinder and find myself staring at the crank. No piston? Nah, that can't be right. Off with the head! That revealed this.
Holy crap! I pulled off the other head to see if there was any damage? Piston looked just fine.
I moved on to the brakes and found I needed a new cable. The rotor is free from the pads so it is not seized. Throttle cable works just fine, along with everything in the carb. The ski's look a little crooked but that will be addressed after I get the motor working.
I intend to use this snowmobile as a beater machine. I want something that I can crash into a tree and not care about. Don't get me wrong, this motor will be running like brand new as long as it doesn't cost me more than it is worth. I think its worth stands at tops, $250, that is being pretty generous too, or so I think. So look at this thread for more pictures and progress! I am sensing a new camera for Christmas too so a video of it running will be mandatory! Piston kit and gasket kit are on their way as we speak. Merry Christmas to all!
