picked up some 310, 320, and 330 mains and 27.5 pilots today. after playing around with several combinations, ive found that the 310's with the 27.5 pilots give me a really good idle and almost flipped me off my shee as it came up almost vertical on on a wheelie. has great throttle response an pulls and sounds terrific. put the clip in the 4th position down from the blunt end and 1 turn out on my airscrews. even though i still have not broken in the new piston's and rings and have'nt been able to open it up all the way yet, this set up feels really good. i'll be takeing it to barstow on new years along with my other mains. i'll do one of those plug chops as suggested by banchheeta and send in some pics. hopefully this set up will work. nothing worse than spending a whole weekend working on a bike and not riding it. thanks again for all your input.

i'm starting to get a grasp on how the mechanics of each circuit effects one another and i actually think i made some progress today. although i was'nt able to pick up the new pilots and mains, i did get to toy with the needle clip position. i have to admit though i can only blame myself for my slow progress. turns out, i had originally essembled the carb slides backwards (or swapped one another) and that made a big difference on the bottom end. so after i re-assebled, i started from the beginning again came up with the following; 340 mains needle clip on 2nd groove (lean side from blunt end down) 30 pilots airscrew out 1.5 this gave me a very good idle, it had a fairly snappy bottom end, good mid but i've felt it pull harder, and a good top, although i still havent been able to open it up completly yet. when i tried moving the needle clip to the 5th groove (on the lean side )it was'nt as snappy on the throttle response but still pulled pretty good through the other circuits. i think i need to richen it up a bit on the mid section to get it where it should be i know this setup has a little more than i' getting out of it. thanks for all the follow up, it has been key to helping me through this.

well, tried moving the needles up to the 4th clip position and left everything else the the same. it seems to hesitate worse in this position. turned the airscrew out to 2 then 2.5 out and again worse. it also didnt idle as well as when i had the clip in the 2nd position from the blunt end. will be getting some 27.5 pilots tomorrow and some 320 and 330 mains. if i have time i'll try playing with the clip position a couple more times before dropping the pilots. like i said before, ive never tuned a carb before so this is all trial and error for me. does it sound like i'm getting close though.

thanks rocket boy, went to the dealership and all they had were 340 mains,got em, installed em and it pulls awesome. only able to get it to 4th gear (short residential cul-de-sac). however seems to hesitate a little out of the box, have to finger the throttle to get the rpms to kick in but when it does it pulls very hard. tried turning the airscrew out 1/2 to 1 turns , seems to make the hesitation worse. not a noticeably better response when i turn it in either. this is my first time ever trying to tune carbs so maybe i'm takeing baby steps here but your input would really be appiciated. currently at 340 mains 30 pilots 1.5 turns out on airscrew needle clip (blunt end down) 2nd groove. (lean side)

been reading the posts and it sounds like you guys could help me with what i'm sure is a pretty standard setup. have a 95 stock shee. just added vforce3 reeds, fms sst's with turbine core's,boost bottle, reed spacers, k&n dual carb mounted filters and removed the airbox. just rebuilt top end with wiescos (std bore) and run 40:1 super unleaded. i have rebuilt the carbs as follows: 300 mains, 30 pilots,1.5 out on the airscrew, and needle clip in 1 leaner than stock(4 up). does this sound about right or am i too lean on my mains. would greatly appreciate any feedback before i destroy a brand new setup. thanks
