lol<<<<<<<< any waaays we figured out the problem it was the sync tube IT WAS IN THE WRONG PLACE i had it between to over flow tubes jesus im an idoit any ways the things is stupid fast my buddy caried the front tires in fifth hehehe any ways the 35 pilots work awesome so far it feels good on the bottom but a little slugish in the mid range but i got the needle at the bottom click any ways i apperciate all your help and i am sincerly greatful for a website like this once again thank all of you that posted for me!!! ps. ill keep ya posted on other goodies i do to it i think i am going to give it some giggle gas in the spring hehehe>> phat andy~

carb cut awaay is to the intake side i know that thats not it. but what does the little holes in the throat there in the back to little tiny holes if those were pluged would it starve for fuel?? becasue when i choke it with my hands and it gets more gas than air it idles down but then when i take my hands away and it gets more air it revs up and dies like its runing out if fuel at idle~~~~~~~~~well any ways i got sick and tired of it tonight so i played with my nitro car hehe took my mind off it for a while well im going to hit it up again! tomorrow thanks again banchetta appreicate all your help so far....... phat andy~

the k&n's are brand new, factory oiled, it still has the stock carb tops, the tors wires have been cut and twisted together. the bike doesn't start cold without ether or gas squirted in the carb, it idles up and down but always high, and its starts hard as hell if at all when its warm. when you get it warm and gas it it runs fine.. and it'll idle high as hell when its warm, bogs just off idle, you play with it a little and get some r's and it cleans up and runs perfect... if not a little rich.. the airscrews are turned all the way in, if you turn them out it gets worse, it won't idle or rev once you get it running, it runs out of gas... i still think i need a bigger pilot... i'm going to take them apart and go over them with afine tooth comb and look for shavings or something stuck in the passages.. thats the only thing i can think of that might be happening.

ok i checked the bowls and is the one with the needle jet suppose to go in the one with the choke or the other one and yes i do have the equilizer tube in place and i blew out all the orfices also did compression test and air leak down test everything is kosher there too. it all commes down to the idle its lean at idle once i get it past 1/8 throtle its ok and it throws smoke and revs quick but at idle is were my main problem is. i apperciate all your help banchetta got any other ideas?????? thanks ill be watin for more info i am cheking this forum on the hour!!!~~~~~~~ thanks, phat andy~

ya but when i get it started mind you 35 pilots in it and 340 maiins and the needle jet is in the 5 position air screws are all the way in now it starts but its got an eratic idle and it revs out when i choke it with my hands it starts to cool off and run regarly i think honestly that i need bigger pilots it only makes sense dont it? i dont know i need some hella help here!~

So, i get my carbs bored 2mm, get jets, a 280 main and a 35 pilot, (did have a 260 main and a 25 pilot, needle in the 5th position, and this was slightly lean for the cool fall weather in MI) and put it all together.... try to start it, and nothing.. no fire... not even a fart, so with a little persuasion i get it to start and its dead lean.. i mean it won't even run for 30 seconds, changed EVERYTHING.. it seems to run the best with the 260 mains and the 35 pilots.. needle in the 4th position still lean as hell, but at least it starts when you kick it. when you go up to the 280 main it gets even leaner which makes no sense at all to me, tried air screws in all kinds of positions from closed to open 2 turns.. i've been doing some reading and i'm pretty sure i need a much bigger main, something in the 300- 340 range, but i'd like some advice, it has; pro circuits, boysen reeds, spacers, twin k&n's (no airbox), .020 overbore, prolites, 2mm bored carbs. has anyone ever heard of drilling jets? when i look through the mains the 260 actually looks bigger... now its REALLY hard to tell, but i swear they're bigger... the previous owner re-jetted it when the pipes and reeds were done.. but since i've bought it i did the top end, carbs and k&n's... but i have no idea what he did exactly, it has 5n-7 needles in it, i haven't moved it up to the 5th position, i got tired of messin with it and its 4am... ANY help is appreciated, thanks, Andy 'Phat' Wirgau
