2Strokes>4Strokes

Hey guys, I just bought an FMF SST exhaust system and I was wondering if anybody has an idea of what to run for jetting. It's winter here and the temperature ranges from 0-20 most of the time and I'm right at sea level. I also have stock porting, V-Force 3 reeds, boost bottle delete, and a K&N air filter with the air box lid off. If anybody can give me a heads up that would be great. Thanks.
