i recently purchased a pro circuit headpipe and silencer, vforce2 reeds, 1/2in billet reed spacer, K&N filter and outerwears airbox cover so i could remove the lid but not let in the crap lol... i also purchased vitos jet kit... i dont have a clue how to set up the jetting... the kit came with main jet sizes 290 though 340 but it just doesnt make sense when the stock one is 220... ive tried a few things but it just doenst run right... the plug gets a dark wet look so i think its running rich? please can anyone help me?
