Im goin up to flagstaff from phoenix for the cinders race. Anyone know the exact size jet I need? I dont want to get an entire jet kit as I wont need all of them. SOoo... I got the HRC kit, jet and needle from it as well. I forgot what jet came with the kit though.

I live in Tucson and whenever I go up there I drop down 2-3 jet sizes depending on the weather, i will be up there this weekend as well, I'm not sure about the 08 but the 04/05 H.R.C. kit comes with a 185 main jet

I did a search and found a pretty helpful chart, for Flagg. take your main jet size and multiply it time .94 usualy will come out to about 2 jet sizes wokred great for me, with the Ethanol I run a 230 main here and a 220 up there and it runs great
