New to this whole jetting thing. I got a 99 banshee just put on a pair of toomey t5s with there "perfect jet kit". Did the whole drill out the air box and put those vents in. I put there 280 mains and there needle clip on the 4th groove and adjusted the floats. The bike runs mint from 60 to 90 deg. My question is where I live its starting to get cold mid 20s for the highs. Am i better off re jetting or is there any other way i can get by the rejetting process by sealing off the air box holes and adjusting the air screws. Prolly a stupid question i know but i dont know much about these crazy a$$ machines.
