-25°f! Damages found today!

To start, not good to ride in that cold of temps. I discovered today that my PTO side has been whacked! The only thing that we can determine was that my sled was running a tad too lean in the super cold temps and that caused my ring to catch the intake port, this scraping off approx. 2.5" square of the cylinder wall nikisil. So, sled is at the shop waiting for the warranty inspector to approve the work.

Dealer told me that they had at least 8 sleds in the yard that needed new pistons. All failed last Friday and Saturday. So, lesson learned, when it's that cold again. I stay at home.

Holy ****, it was 25 below up there today?!?!?

Dude that sucks my friend from Vernal blew his 900 1M up last week due to the same reason. Jetted for 0 degrees, not 25 below

 

[powdersnobb]

Yeah I don't go out when it's cold. I'm a puss these days. It's pretty much gotta be +10deg at least. Good luck getting that fixed. I think I'll be doing my top end at the end of the season. Just in case.

 

[Dogmeat]

Yeah, even with an EFI sled I kind of frown upon riding in sub-zero temperatures.

I've done it before, but it wasn't fun.

What sled was this on? We were riding M1000's, Mountain Cat 800 (carbed)+600(EFI) and a Mountain Max 700 (Carbed) in 15-25 below over new years and lost the 800.

If not for bad luck you would have no luck at all....


WTF did you do in your past life??????



My cluster gauge went fubar today for no reason....spent a blue bird powder day in the lot kicking the sled. It was awesome.....met another guy who melted down..chilled and drank adult beverages watching sled vids in the lot all day.

Guess its all part of the game....and I am playing to win!

Fawk Dizz. I don't know.

Spoke with Donovan for over an hour yesterday and that's the only thing we can think of. There are no signs of deto on the head. I went out to she shop and checked out my other head and there were signs of deto on that particular side's dome. So the only thing that I can think of is that the ring on that piston was fatigued enough that the minus 25 temps became the straw that broke the camels back. It was fine under normal circumstances and had I known, all I would have done is replace the ring and been riding today. But since we can't see through our motors...

And to the other guy, it's an 2009 XP, so in two weeks, I'll have a new motor basically, I got a new crank last year.

I went riding in -27*C on the 1st, and that was too cold, going 120km/h (70mp/h) through a wide open field for excessive amount of time, means you get some nice frost bite on anything thats not covered. We lucked out and didn't have any damage happen to our machines.

sorry to hear that. i did a little trail ride last sunday up to corona. noticed a little extra heat on the egt.......i know lots of guys use F/A readings, but the ole standby egt has kept me from torching a motor, even in the "lean" times poo has had recently. cheapest insurance i have ever bought. of course, that didn't help when my brother took a TOTALLY innocent "off", just stepping off the sled at 5 mph and tweaking his knee.....turned out to actually be a fracture of his fibula condial. feck.

 

[PJ-Hunter]

Ya. Guess I'll see about getting an EGT gauge. Maybe I can finagle my old Avenger from the kid that bought my old 670mod.

 

[LabRat]

Not sure about the '09 XP, but my REV has a valve you can turn to recirculate some warm air back into the carbs for ultra-cold days. I've never used it as I've never rode in that low of temps (outside of growing up in WI), but I may read up on it now in case the need arises. Do XPs (carb'd) have that same valve on the carbs?

 

[tudizzle]

yes

 

[Engine Pro 5x]

And I thought that was a trick to keep the old sleds running. My 77 Liqufire had a hose on the air-box you changed over to heated air for those colder days >>>>.

 

[bushy]

mine has efi

 

[PJ-Hunter]

mine has efi

But it blows up just as much.

According to the dealer, lots of sleds (not just Doos) got turned in to them with the same problems.

 

[Tec]

It's kinda weird that is happening? It's definitely colder in AK and people ride there sled all over the place to get around.

PJ:

Your sled is carbed?

Hey now, lets keep the questions simple!

 

[Ox]

Just hopin' that a fuel infected motor doesn't have this issue!

Oh no, my record puts yours technicians to shame, but I do ride a lot and do my own wrenching. What's your excuse? and I haven't burnt down since may of 08..
