Jetting for the winter

[blastermaster01]

I live in NC on the coast and the lowest it gets here is like 20 or 30 the whole winter and it's usually like 40-50 on average and I was wondering if it's still necessary to re-jet..oh and its been like 23 here the last week and its gonna snow thursday so if that helps any

I would go up a size or so just to be careful. Check your plug to see what it's telling you. When it gets warmer, the bike will bog with the larger jet, so you'll know when to switch back down to a smaller size.

Just like xjma said its best to go up a size or two... even more sometimes.
I have ran 60-80* jetting when its -6* and was fine, but I never really pushed it. If you plan to do anything serious I would go up a size or two and see how it feels.

every 20 degress colder you go up on the main jet 1 size.
