Hey dre unless you got the carb word has,the needle jet is not tunable but there is a spring under the cap in the slide that can be forced up a bit to run a little richer with a couple shims,beer cans work great.Tried to follow your posts back,might need a refresher,but your not running an open air box and stock main jet. all our tuneing is with open air box and BIGGER JETS!!!You want to open the jets up till they sputter than drop down a hair a 95# main seems to be the best start or start drilling,That motor has some life left,you will be suprized,for us with this tuneing We have had to go up in weight to get the power back at the top end if i were to run a 6 or 7g roller I would top out so fast 0 to 40 and be working the motor at meltdown stage if you pushed any harder,might be smoking the tire and wheelying at the same time If the belt holds Ha!So I'd say bigger jets and k/n filter,if it does blow you'll need this stuff for the big bore kit anyway!Forgot what year you had seems the 99 to 2001 have a better stock carb.Word has come to the dark side,these bikes are banned in california!
