so i no wat im workin with, i think the stock main is 122 and a 42 pilot.

i have a K&N filter on and if i get a sparks pipe wat should i bump the jetting up to.

im thinkin 165-170 main, 45 pilot, a HRC needle on 3rd notch, F/A screw out 1 3/4 to 2 turns out. does that sound good or wat do ya'll think. help me out im new to the R's cause ive been workin on a EX so i no kinda wat im doin!!

just dont be afraid to adjust it again, too many people try to set it and forget it....jetting needs minor tweaks from time to time depending on conditions, and every one is in to big a rush to make it right.....take your time and take it apart as many times as it takes to make it perfect, your piston and wallet will thank you
