Will temperatures in the low 20 damage the Polaris sportsman 450

Hello, -

I tried to find information on the outdoors temperature range for a Polaris Sportsman 450, but did not find anything.

This is the number for Polaris Customer Service:
1 (888) 765-2747
Hours: Monday-Friday, 7 am - 7 pm, Central Time

They have a convoluted process for sending an email, but I suspect no one will be checking emails outside the Customer Service hours for phone answers. See this page:

To send an email, first you need to search the Help Center. I used the word "temperature" and clicked on Search. Then the form to fill out to send an email appeared.

Atv charging problems

115 ac volts at idle seems very high to me. if all 3 coils are putting out the same voltage I'd say its ok.

How do I replace a fuel filter on a 2006 Polaris Sportsman 450

The part you should have got would be #2520464 from polaris, this is a quick disconnect filter that is located not in the tank, but under the frame just behind and above the radiator. if you take your front box off you'll be able to get a good look at it. pretty easy to install. As for the tank, polaris doesn't offer service parts for thier pumps, which have a screen on them

Engine won't idle /sometimes backfires

Check the MAF-MAP SENCER or it's a throttle position sencer is bad check both by replacing them and see if it works or the last result is idle control valve

2004 sportsman 400 4x4 shifts late and hard going into high end

polaris drives are variable speed. they only have 2 ranges plus reverse. it sounds like either the driven clutch is slipping or the trans is slipping. the gear cogs inside may not be locking in properly and the shifter rods may need adjustment.

2006 450 sportsman. Will start&idle. Increasing rpm will kill it sometimes.Is the slide in the carb vacuum activated because sometimes it will move sometimes it wont. Seems like not enough air and it...

Yes it is vacuum activated, I would check your vacuum lines for cracks and make sure they are snug. I would also check your air filter. If all looks good and it still happens I would clean youe carb because some dirt, rust or debris could have made its way there causing the inlet needle valve to be stuck open or it could be worn. Hope this helped
