why does toomey include 280s in their perfect jetting kit? that would be on the kinda lean side right? im like in the same boat as you right now, so i have the 280s that came with the t5s, and i bought 290s 300s, 310s and 320s. i have been told the 300s or 310s will prob be best for me, im also going to be running the cfm airbox w/unis and +4 timing.

yeah,I agree with the 310 or 300's. Especially with k&n.I think the perfect jetting kit is for uni and maybe stock box with those silly little 1" filters in the bix.

u guys should post your location in your member info. temp makes huge difference. i started with 27.5's, 310's middle clip, and still too lean. below zero @ sea level
