I change my main to 158 and my pilot to a 48. My needle is one clip richer and my bike runs great. I'm in iowa :)

I put a 215 seems to run great, check your plug and when it stays brown thats what you want.

Is your snorkel removed? Mine is and I run a 160 and 48 in NJ with excellent results. The snorkel restriction could cause it to run a little fat.
