Cold starts (-35C and colder)??

[ski_bum]

did someone say something about cold? I have the inline rad heater on my Nytro, its key for up here... -43 at 9am today.

Its cold like that here most of the winter.

No its not, no where in canada is it that cold most of the winter.

And these are temps without windchill you have to use when talking about an engine, as the engine at startup will be the ambient temperature.. Windchill will only affect how fast it cools down to ambient once warming up, so its unlikely to be much past -30 for many days in a row.

The weakest point in any of this is the battery, followed by oil weight, and then fuel (any water content) If you have any way of keeping the battery warm it would be a huge help (even taking it inside) and run low weight oil.

Exactly, Everyone looks at the windchill and thinks that is the actual temperature, it is not, it's simply a calculation on how fast things will cool off. You need to look at the actual temperature to know how cold it is for your sled.

Who in their right minds rides a snowmobile in those temps anyhow? I rode in 0 degree weather once and decided that was as cold as I can take it and still be semi- comfortable. Hands only. I have Klim's best gloves and the yamaheater and hands still got cold. Also, helmet tends to fog in very cold weather. Do you guys really have fun in -20 and below weather?

If we wait around for warmer weather it'll be summer by then. Just have to ride hard to stay warm.

If we only rode in 0 Fahrenheit (-18c) or warmer , there would be very few days that I could ride. As it is I can only get out on weekends. Even though winter in Canada feels like 8 months long, the riding season can be anywhere from 6 weeks to 4 months. Depends on where you live and if your lucky to get the snow early. Right now we have maybe 3 inches of snow, no way I am taking my sled out in that. I could drive 3 hrs north and get into some good snow but that starts getting expensive.

This is how cold it is.

Only out west you say.

I apologize Mr.Literal,,I guess I should have said "quite often" it gets cold like that. And I am also referring to the temp in the AM hours, when you would be looking to start the machine.

When your group have booked their holidays and you are doing a 7 day loop you keep going and make the best of it. Besides every trip is a new adventure. 4 out of 5 of our coldest trips have been in the Timmins to Cochrane area in Ontario. All of these have hit -40 and that is actual temperature. It is thermals regular layer extra layer, and Klim suit. Klim towagatee gloves and muffs. 0F = -18C and is a lot fun to sled in as we probably do half our sledding in -10 to -20C.

I've started my nytro as cold as -32*C. It'll start and die then usually it will go the second time. This year it seems to take a couple more tries for some reason. Gas in it is 3 months old though. Thinking it may have something to do with it.

-30 to -40 here now pretty much solid now for the last 3 weeks. Had a couple little breaks but not much. With enough layers its not bad to ride in.

A riding buddy of mine, a cat guy, is planning to buy a new Cat and was wanting to get the one powered by the Nytro mill. The issue is he is a trapper and uses his sled for that purpose as well as pleasure riding. This past week at his trapping cabin the temp was -38c (-36.4F) and he needs his sled to start.

I keep my Nytro in a heated shop and most of the time I ride from there or after a short ride in the truck box. I have only started my Nytro in extreme cold a handful of times (and it always started) so I can't really provide him much feedback.

I'm looking for feedback from a few guys who can speak from experience keeping their Nytros outside and staring them in that -30 and colder range on a consistent basis.

Thanks for any feedback

NOTE: No power at the cabin for any kind of heater for the sled.

I have left mine out doors in -30 and coler for weeks at time here in labrador city the last 3 weeks its been coler then -30 and every time I go out I switch on the key wait for the fuel pump to prime and start her. Usually she wount go first try she will catch and stall second time she runs perfect.. Very good skidoo in the cold... Last year it was -47 up north at the camp left out side all night and half the next day same thing second time started like a charm unlike some other sleds that wount start at all...

Thanks for the info guys, kind confirmed what I have experienced with mine.

I am aware there are inline coolant heaters and such however this is a remote trapping cabin with no extra power. The solar system is taxed as much as it can be and can't support a heater for the sled.

I will pass on the intel

Don't give up yet! Here's what I'd do: Buy a 12' x 20' insulated tarp (https://www.acklandsgrainger.com/AGIPor ... F392122000) to cover the whole sled, pick up a couple Anti-Gravity battery packs and hook them up in parallel to a 12VDC heater (http://www.roadtrucker.com/12-volt-heat ... eating.htm) mounted inside the engine compartment nose cone or near the oil tank. About an hour before you need to start the sled, run the heater. You'd be surprised at how little heat you need to make the sled start easier. Make sure you let us know what you end up doing and how successful you are.

Giving up? Just collecting info and passing it along.

Again remote trapping cabin, no insulated tarps, batteries or heaters. Just a sled parked in the bush that needs to start in the cold. If he has to do all that then he'd just buy another 2-stroke. His crossfire has never failed to start, if I told him to do all that he'd laugh.

 

[hypnotiz3r]

I leave mine parked outside all winter and on the nights it dips to the -40 mark, I have issues starting in the morning and need to put some juice on the battery. Just got the sled last January and not sure how many miles on the spark plugs but I know they play a big part and should be changed every season. I'll be doing the spark plugs on mine very soon...put in a new battery this season as well.

 

[Sled Dog]

Thanks revster in a pinch and you need to get it to start I would pour water over mine too. The sled gets wet all day long so I don't see any real problem sometimes my rx steering gets a little stiff from the half frozen snow and ice built up from snow melting on the engine all day. Good tip to know!
