Thermostat setpoint for 2022 850 RMK 155 - 95°?

Yea they have been like that since 2018, used to be 125F
The fix for pros running hot but using a doo t-stat was the same thing. They started at 95*.
Yup. Been that way since 2018.
98.6* is spec in manual

3 weeks ago I got the same sled, it has about 70 miles on it. Last Saturday I got another 2022 pro 850 slash 165, used, had about 400 miles on it. Today, running on the trail to and from the hill, the 165 was running about 30 degrees hotter than the 155. It was hard to keep the 165 below 170 degrees. Once out in the deep stuff the 155 was running about 95 degrees and 165 was running about 108. I wouldn't expect such a large swing in temp between the 2 sleds while on the trail. The AXYS platform was easier to cool down, just pull over and stack a bunch of snow on the tunnel.
It makes sense that the shorter track sleds bring more snow back into the heat exchanger area on matryx models.
If you look at it, the longer tunnel 165 should probably have a few more inches of heat exchanger extension beyond the tank to compensate. But that would require retooling and different parts, which is inefficient for polaris.
Alternately/additionally, I wonder if anyone has experimented beyond the great snow flap mod posted on this forum that helps move more snow back into the tunnel?

Ok, that makes sense. The 165 slash has more of a tail feather, not even sure you can call it a snow flap. The 155 has a healthy snow flap by comparison.
Slash vs normal tunnel. Track length doesn't really matter.
Only time I've stacked snow was towing. I just pull off and chainsaw it in for 15 seconds. Drops temps 20-30* within a minute.
Well, maybe. The sled this one is replacing was a 2018 AXYS, and the stat there seemed to be set right around 106.
Pretty all mountain sleds these days run hot on the trails. It’s the result of competing brands on weight loss. Then pretty cold temps off trail, under 100 degrees. We just watch temps super close on hard pack trail, or if you lucky, avoid trails altogether
