last weekend i was in bad snow conditions on the trails and noticed the temp got up to 200 quick, tried all i could to keep it under 200 but did it hit 213 once and when it did start to run crappy. what is the max temp i would want to run the sled at? no more front rad but i dont have scratchers, runs at 125-130 in pow and 140-170 depending on the trail, just curious to what the redline for temp is.
how hot can the 9 get?

- Start date
Glad to see this post...I have never taken my 9 out yet and was wondering the same. My rad is still in, is it a must to remove? I ride in the upper Michigan groomed trails, am I setting myself up for disaster?
Definitely get some scratchers on that thing NOW before you burn something up. The 900 is designed to run COLD by motor standards, as mentioned, it is happy at 126*. Once you get around 200-205 (not positive on the exact number) it will go into limp mode and kill one cylinder to try to save itself from damage. If you get it any hotter than you did, you run the risk of melting things... there was a post about a week ago someone got their 900 up around 225 I believe and they melted the o-rings in the head.
Personally, if I was to ever see temps over 180 I would stop and start packing on the snow on the boards just to be safe.

Do you have good circulation? I fought and fought with a VE tunnel and it kept air locking. I finally fired the sled and lifted the front straight up with a skid loader to get the air out.
I had two tunnels like yours and faught with it on both. It just seems with that set up there is a lot of corners and bends for the air to hide.

Most definitely!!
They're not so much for the hyfaxes as they are for your cooling. I broke off a scratcher on Sunday and my temps on the trail going down were 15 degrees higher, just missing one of them.
I dont have a front radiator, I installed a SLP airbox. When I'm on trail, my scratchers are down, no exceptions.
And 1 more thing I've heard over and over and over again on this site..... Vents, vents and more vents.
If your a trail runner, your better off to leave it in. The RMK guys that ride the mountains take them out for 2 reasons: Weight savings, and when riding in the trees the radiator setup only makes heating problems worse as the nose cone is often under the snow, preventing air flow to the radiator and causing it to 'boil over' and return that hot coolant back to the motor.
Cool! I'm cuttin' the side panels out in the morning for the FNI vents and the shock wells too, also 2 SLP vents in the dash, I have the FNI air intake and clutch gaurd already Dynoport pipe and can. So I'm thinkin' I should be good to go.
i have been wondering the same thing as i bought a new 06 switchback 900 and i will pretty much be doing all of my riding groomed trails up in the upper pennisula of michigan. the sled is all stock. i havent decided of what to add or what is good to add to not only keep the heat down, but also try to prevent any of the other problems that come up frequent in most of these sleds. of course i will be looking for any powder i can off trail but most will be on trail riding in the u.p. of michigan.
any thoughts or ideas would be great.
thanks

Good advice.
ok thanks thats what i needed to hear. ya i will only see temps 150+ if im on really packed trail....... I try to stay clear from them in all honesty but some times unadvoidable. any time i got to 160 i packed the hell out of every thing that conducted heat lol. but i had some near dirt trail to drive on to get to hunters range and thats when i got hot. other wise im fine. just wanted to know then to emergency stage left to the trees in search of.... anything
currently making a set of wire rope scratchers, where on the skid is best for them? mid or front of the skid? again thanks for the help... i promise i will not let the big 9 see that kinda heat again

The 9 will start to go into limp mode at 176* if your flipper is squeezed to the handle bars. If you are varying your throttle use you could take this motor to over 220* with out it going into limp....been there, done that way back when it was on warrenty...
You probably won't see the temp light come on untill you get to 230*....
Then I removed the radiator and that was some 5000 miles ago.

Packed trail no front rad but with scratchers 155-160, running extra slow on hard pack without scratchers being able to be effective 200 and goes to limp mode. <--------Limp mode= to hot moral story dont go slow on hard pack, and get scratchers.
Hey Ridehard, check your windows in your track, see if they have plenty of melted plastic. Scratchers do 2 things, keep temps down and save hifaxes. If my temps go above 150, scratchers come down,

I wasn't riding it so don't know when it went into limp mode or if it did. At that temp pretty sure it did. I run mostly trail, not much powder here so left the rad in.
