Default Cold weather Questions on 700's

my 600 is the same way, but i find if you pull the choke all the way out to start it then push it back in to the point where the choke rod is only a quarter inch out it will not stall. it won't idle as well as it will with the choke out a half inch but it won't load up and stall.

EFI's don't have chokes. only carbed models do.

I would much rather deal with a minor problem such as a slow idle in cold weather than have the expensive and hard to deal with EFI problem you are sure to have later on in the life of your quad.

if u ride in alot of snow check out your air filter sometimes snow will accumulate around your filter melt, then freeze making your engine starve for air

Polaris has 'cold weather upgrade' bulletin for carburated machines. Essentially it involves removing the brass plug which prevents adjustment of the idle circuit screw. Basically, the EPA mandates this screw be adjusted at the factory to meet EPA exhaust emmission standards and then they "seal the deal" by installing a brass plug over the idle circuit adjustment screw so that it can not be changed.

The cure is to drill a hole in the brass plug, screw in a sheetmetal screw and pull out the brass plug with pliers. Once the brass plug is out you can then adjust the idle circuit screw. Polaris has a bulletin on this and the adjustability of the the idle circuit screw is what solves the cold weather starting and cold operatring problems.

All of the carburated machines have the brass plug. How poorly the machine runs in very cold temps is just a matter of the adjustment screw was set at the factory. Mine runs like crap in temps below freezing until it's 100% warmed up. I'm bringing it into the dealer to have them do the fix before winter.
