With the mods that i have, pipe, rad valve, K&N, and i pre-mix, what size jet should i use during the winter, spring/fall, and summer? I live in wisconsin at about 800ft above sea level. If anything, i want to run a little rich. I also thought about running a 32:1 gas/oil mixture.

 

my blaster runs well with a 280, thats with pipe, scilencer, and k&N
