Bought a 2005 efi 700 kq, no problems starting

 

i just got an 06 arctic cat 400 4x4 auto and it starts right up in the cold but it takes a good 15 minutes to be able to ride it without it stalling when you get off the gas

 

My kodiak allways starts (knock on wood). I've noticed that allot of the folks that have changed to aftermarket air cleaners have trouble in cold weather. The extra flow makes the mixture too lean.

Change your plug once a season and with most atv's you won't have a problem.
