papersniper Posted April 1, 2014 Report Share Posted April 1, 2014 Have a fresh top end with just barely enuf time for break in. Stock bore .Wiseco pro-lites. 21cc domes. Vf4 reeds. T6 pipes. "i know they suck but got brand new set for 300$ "stock mikuni carbs. Tors removed. Stock box. lid removed pro flo adapter with K&n filter with outerwear. Currently at 150 and 152 psi. Elevation is from 600ft to 1300ft. Mixing 32:1 with 93 octane. Stock pilots stock needle on 5th clip 1.5 turns out and 280 mains. Bike starts just doesn't wana idle cold . Do i need to up the pilot to maybe a 27.5 or go on to a .30 To cure the idle problem? Haven't really got to open up to get on the main jet because i smoked the clutch within 30 mins after the build. but I'm pretty sure i need to fatten both main and pilots?? Temp is bout 60 to 70 here in middle Tn rite now .Thanks for any input Quote Link to comment Share on other sites More sharing options...
wayne_smith97 Posted April 1, 2014 Report Share Posted April 1, 2014 Main is probably fine but I would definitely go up on pilot Quote Link to comment Share on other sites More sharing options...
Zillaguy Posted April 1, 2014 Report Share Posted April 1, 2014 290 main 27.5 pilot should be perfect for your setup.. Also trya set of aftermarket needles in the slides... Makes a HUGE difference in the mid range... Quote Link to comment Share on other sites More sharing options...
papersniper Posted April 1, 2014 Author Report Share Posted April 1, 2014 ill probably give a 290 and 27.5 a try. i had thought about toomey needles but iv heard so many mixed opinions on them. i do mostly trail riding and a lot of hillclimbs . So anything to help midrange would be a plus. it actually seems to have good bottom and midrange power just doesn't like to idle and a what little i got on the main it kinda fell off but i figured thats due to the t6 pipes. when i got this shee it was bone stock so I'm kinda shooting in the dark rite now on jetting it.

BUILDER Posted April 2, 2014 Report Share Posted April 2, 2014 Your main should be plenty big for your setup. The pilot needs to go up but I would leave the main alone that is a big main for a bike running the air box Quote Link to comment Share on other sites More sharing options...
papersniper Posted April 3, 2014 Author Report Share Posted April 3, 2014 guess i should have mentioned that the air box top is removed. i have a set of 30 pilots on the way. May try needles later on after get it broke in good. Thanks for the help guys. Quote Link to comment Share on other sites More sharing options...
BUILDER Posted April 3, 2014 Report Share Posted April 3, 2014 Main is still plenty big even with the top off the air box. You should have only gone to a 27.5 pilot a 30 is probably going to be too big for that setup. On the pilot it is generally best to try and go up one size at a time.

papersniper Posted April 3, 2014 Author Report Share Posted April 3, 2014 i have a buddy that said hed trade me some 27.5s for the .030s only reason i got the 30s is because i got a kit with 30 and 280/290/300 a mains and needles and gaskets for 17$ . for some reason everybodys bikes around here seem to like a lot of fuel and where we ride and i would rather sacrifice a little power to be little rich "and just keep it piped n cleaned out" because we also have some slower hill climbs with rocks and some slow technical trails and have seem a lot of heating problems and that may or may not be due to lean set ups but with fresh build i dont wana chance it. but i will take your advice with the 27 pilots . Thanks again Quote Link to comment Share on other sites More sharing options...
