Well, the colder the air the more air flows trough the engine. I`ll probably ride my quad as low as -15 degreas celsius. The jetting is stock now, should I rejet my carb for the winther?

If the bike is all stock you should be fine!

Colder air requires more fuel. I would rejet richer for the cold. Your bike will run better and your motor will last longer if it's jetted properly.

I have already went up one main jet size since summer.

Thanks. I have a 05, what are the stock main and pilot on this? What would you guess I would need for temps below zero? As you might see I don`t have a clue bout this. Just ordered a shop manual to help me out a bit.

Hey roundsy you should give a 45 pilot a try I like it better than the 42,and now that it is getting colder its even better. (just a thought):D the 42 is pretty lean. ever look at the header at idle at night. mine was red hot about 12 in back. know only about 4 in
