got a 550 xp and was going to burn around the yard today and the temp was -20 celcius, turned the key and the machine just turned over and over and over it fired but didnt keep running. I did that five times and eventually keeped running.

I thought for being fuel injected it would strart a lot better, I was not to impressed.
Has anybody else have that issue with cold starts.

 

I have had no trouble. The coldest I started mine was 0 degrees f. I think it should start easier for you.

 

thats what i thought because when your hunting it has to start. i will phone the dealer because its still under warranty and see what they say.

 

My guess would be the dealer put regular oil in at setup rather than cold weather oil. Change the engine oil to the recommended winter viscosity for your temps, and you should be fine. When the Grizzly 700EFI came out, many owners had problems with hard starting Grizzlies in the cold.

It turned out Yamaha required 5w-30 in winter. The Grizz was designed not to start in severe cold without the proper weight oil installed. This was done to keep the engine from seizing before the oil was flowing. Once the proper oil was added, the Grizz would start in any temp without incident.

It could be Polaris did the same thing. Read your owners manual.

 

Yes that is what I would do too- talk to the dealer.. Keep us posted on what happens. This is my 2nd efi from polaris and i have never had a problem starting and it gets cold here too. Polaris only reccomends one oil so i doubt that is the problem.

 

well the oil im running is still the break in oil then after its the recommend 2w-50 but my 08 recommends 0w-40.
It only has 20 miles on it.

Im thinking it could be condensation in the tank because it has a half of tank and the day before it was -10 celcius. when i was driving it.

 

It may be that your battery isn't handling the deep cold very well. The reduction in battery output may be keeping the electronic ignition from working properly. My carb version (rejetted to improve cold weather starts) was doing exactly the same thing, so I used a bit of starter fluid. It started right up all was well after that. You may just need to help out your battery a little bit in the colder temps.

Keep in mind that the dealer will probably keep it in the heated shop while testing it, so his results may not match yours. You may want to try the starter fluid before going to the dealer.

Report back!

 

Have started mine @ -10 kicked right over, was a bit ruff for a few seconds. Could have some moisture in fuel, maybe put some iso heet in full tank.

 

ya im going to try putting fuel deicer in the tank. You could be right about the battery that its not turning over fast enough my 1997 used to do that.

Talked to the dealer he told me that its to cold and the windchill was to high, -25C
and its the first winter for these machines and they dont know.

I guess some people think im just to crazy to be going out quading at that kind of temps.

 

EFI should prevent the ignition and air-fuel ratio from being affected by low temperatures. That's one of the biggest reasons for EFI. So the problem is likely elsewhere... battery, poor/contaminated fuel, perhaps a combination of factors.

How full is your fuel tank? If there's any room at all, top it off with fresh fuel to reduce the ratio of water/whatever. Add the deicer. Temporarily jump in a room-temperature car battery (lots of CCA's) to assist the existing one.

But I betcha the starter fluid will get it going almost instantly....
