300 degrees is too high...lol kidding. i would think once you hit the 200 degree mark I would be looking for some snow to get up on the exchangers. just my opinion

Maybe Polaris are different, but my Cat would send the ECU into limp mode (cuts power) before it ever got to 200*. Personally, if I ever get to 160* I'm looking hard for some loose snow. My Cat runs 120* pretty consistently. I've read 120*-140* is pretty average for a 2-stroke...depends on your riding conditions also though.

I know the 800s run about 126.

The 900s run in the 150s and 160s regularly.

I would guess your 600 should be seeing coolant temps in the 120s or 130s tops.

What would be normal for exhaust temps
"Normal" would be whatever they read on your sled, after being
properly tuned useing piston wash and plug color.

there are wayyy to many variables to exaust temps. giving you an average reading would be like wiping before you poop just doesnt make any sense
