melting point temp?

[otterpoo]

Has anyone notice or know the average temp these 900 are reaching when they have an engine burn up? What temp does it reach before it will shut itself down?

As far as I know, the motor will not shut it self down, but here is a good way to keep your motor happy....

Yup, Thermostat opens at 126, depending on conditions mine likes to run between 130-140. I would put the scratchers down in less than 2-3" of fresh snow or if temps go above 150-155... You can run it hotter than that of course, but at the cost of performance. 'Limp mode' activates at a little over 200*F if I remember correctly and cuts power to 1 cylinder. (Don't let it get that hot, lol. I have read of Head Gaskets melting @ 215*F) If snow conditions suck I usually start piling snow on the running boards at about 165-170*F, that helps tremendously.

Piling snow on the rear cooler also works very well to cool the sled down if it is getting hot.

Cooling System

I had heard that the cooling system had a double loop in it (front & rear)and there's a kit to make it a continuous, that's better?
