you say you put in a kit. what kind of needles. anything but mikuni you will have to jet to the instructions that come with the kit.
everything you need info wise is in the jetting section of the lincs.....17.5 or 20 pilots.. depending on the exhaust, weather modified or full performance the mains are 147 for modified and 150 for full performance.. two shims total they mic to .05. i'm not a machinist so i don't know if it's tenths or hundreds. the info is in the linc and there's a picture of the needle and washers.the pms screws should be 3 to 3.5. i'm not sure about the needle you have but i think if it's a dyno needle the bike would run pretty bad. and when you turn the screws all the way in you should feel the tip protruding into the venturi, make sure the threads are not bunged..... you can get needles from partzilla for $18.00 each or jets r us. be sure to get pre 2003 they';re easier to use.the problem might be needles or pilot error,..... i've been tuning (sincing) a 650 suzuki all week so go over and over your work
