I was just wondering what size jets,I should run in my carb? I have a stock cv carb with a stock T88b motor.The only up grades are a free flow air cleaner (Big sucker1)and free flowing exshaust. It has a 45 slow jet now and a 190 main. Should I just move the slow jet up to a 46 and leave the 190. I live in iowa so altiude would be of no concern.Just wanted so opins on the subject.Thanks SM 2005 FXST

 

if you have a free flowing exhuast you would def want to change your main jet to to at least a 200. it will make a big diffrence. you have more air now so you need more gas. the secondary jet i would change to 48. i have played with jets for days and i think that is the best mixture for free flowing. if you really want alot more peformance the minkuni 42mm runs great too. easy carb to intall too
