I was up at our camp this weekend and got the sleds out to clean them up, grease suspension, etc (yeah, yeah a little late). I started my '03 Pro-X 600 and it sounded funny (running on one cylinder). The clutch side was cold so I pulled the plug and there was coolant on it. Here is what is odd to me..... The last time we rode in March everything was fine. The coolant is still full so it must have just happened. I cannot remember exactly, but I think I had run my machines at Memorial Day and let them idle for a few minutes. Nowhere near long enough that they could have overheated I wouldn't think? I usually feel the head until they are getting pretty warm and that's it, so again I cannot believe I hurt it then. From what I could see the plug looked like it was probably pretty good otherwise and the piston looks dark. My guess would be that it's just a head gasket but does that make sense that it could happen like that? Sled has 2700 miles on it. I am thinking I will get a head gasket and bring it next time I go up (Labor Day) and hope that is it. Thoughts/advice?
Thanks,
Scott
