Try to keep up genius.
1) hot high fax
2)hot belt drive
3)hot clutches/belt
4) hot coolant Temps
5) warmer pipe
All causing heat which can lead to something starting on fire, which comes from low snow, riding trails and lakes.
not saying this is cause of this sled but have seen many sleds not just a pro rmk start on fire from something getting hot or spilled oil/gas igniting. May have something to do with it
Yeah, uh, you're wrong.
My favorite mountain riding destination is 65 miles down a dirt road that does not get plowed in winter. State highway dept barricades it with a sign that says TRAVEL AT OWN RISK. It gets run by sledders and dog mushers. More often than not, the snow is hard-packed. I run my 163 Pro with scratchers down on this road. Fortunately it's a road and not a whooped out trail. 99% of the time it's smooth and fast so it's easy to run 50MPH and faster. I never have a cooling problem (so long as I don't break both scratchers).
I ride here 5-6 times a season which means I log at least 700 miles a season on this "trail". I have yet to burn up a hyfax, much less catch on fire.
