Perhaps been covered before but I don't remember when. Was riding this weekend with a couple doos and a newer Polaris 800. After riding some distance I noticed my right foot getting a little warm. Felt the chaincase and I could hold my hand it on it but definitely hot. My guess it was about 100-125 degrees.
Did the same with the Polaris and the two doos they were considerably cooler.
Anyone else notice this? Might be something to this 1.5 turns. Not doing anything about it and not particular worried. Just asking around.
almost 500 miles on it. Still digging it.

I would think some of it would have to do with the oil tank, the oil must have some heat to it when it goes back into the tank and the exhaust might have a small parts to play in it.

I was out this weekend and weather finally warmed up. My chain case was hot. My guess would be there is a hell of a lot of heat in that corner. Engine oil tank attached to the chain case.? And muffler. Got to make sure we run 100 percent synthetic oil in that chain case.

Oil and exhaust heat is the reason.

Was paying attension to chain case temp yesterday. After riding 60ish for about 8 miles the chain case was hot enough that you could only hold hand on it for a short time. The oil tank was much hotter, could only touch it for a second or 2. Coolant temp was 165*F. Appears chain case is picking up oil tank heat which is more than likely.
Checked my Rage today in similar conditions and chain case was barely luke warm.
This poor engineering causes more negatives than one can count.
Spring of 2011 at the showing of the new procross sled my biggest concern was the chain case/oil tank.
What if a bolt comes loose and drills a hole into the oil tank. Engine failure. Now I went and bought a sled with that oil tank, guess I'm the idiot.

Today's lubricants are better than you think.
Take a Catapillar C7 engine, increase the size of the turbo so that it pumps out 50 horsepower more than any commercial engine. Stuff it in a sealed Steel box with external cooling and fresh air and run it continuously near full power for 100s of thousands of miles pulling over 20 tons in temperatures approaching or exceeding 130 degrees and the only failure you will see is a few turbos fried because the driver did not go through a couple minute cool down cycle. 165 degrees is no big deal, may even help the chaincase lube penetrate the chain better and the cleaning agents work better.

0-W30 winter oil down to -50F

I agree, if its 100% pure synthetic lube that you put in the chanincase that's specifically designed for that I don't see any issues at all... As Testmaster said, look at some of the operating temps of diesels, loader transmissions etc... They take special oil yes but that oil is meant for that... I wouldn't worry about it at all... On a side note if the chain tension isn't set correctly then that could definitely have an effect chaincase heat!
