i got hmf full exhaust and they recomend mikuni small 150 in the left and 155 in the right. i found a conversion table and it said 150 mikuni was equal to a 160 dynojet and 155 was equal to 165. my dyno jet kit didnt come with that big of jets. but it says in the manual that i have a stage 2 jet kit for full exhaust. what should i do

visit your local dealer and get the mikuni mains for like 4.50 a piece. if your pipe recomends mikuni then i would try those first as they have done all the work at the manufacturer in tuning it with that exhaust. JMO

i would use the dyno-jet kit since u already have it, just pull out the old instructions and re-jet according to elevation/mods.
Basic stage 2 dyno-jet kit comes with jets up to 148-150 i believe and im pretty sure thier flow number instead of sized like mikunis are so thier usually "smaller" then mikunis (think prime expample is the jets that come in stage 2 dyno-jet kits which are designed for piped/intake are all in 140's range and most pipe-jetted bikes using mikunis are 160-165+)

Also, the conversion table most commonly found floating around is backwards. The mikuni and dynojets names are on the wrong sides.

Not many conversion table out there are correct, all the way through. If you are going to use the DJ kit, i would run a 146/148 combo. If you run mikuni jets, i would run a 160/165 to start. You will probably have to adjust this per your needs.

krauss, what is your altitude? I run 150/155 but I'm at about 4700 feet.
