PJ 34 single carb

[Ruko]

OK I have been fighting with this for a couple weeks now. I put a single pj34 on my girlfriends Banshee to get a softer throttle, and this is being a real bitch to get set up. It's a Trinity intake that I bought used, and I got the Keihin pj34 off a buddies 250r. It was way off when I started... It had a 38 pilot with a DGK needle and 260 main. I switched to a 55 pilot and now it idles nice... then I went to a CEK needle and stayed with the 260 main. I tried running it and it sputters bad from 1/2 to 3/4 throttle, then smooths out and pulls good in the power band. I tried moving the clip up and down in each postion but it didn't seem to make much difference. It also popped through the pipes once in a while so we thought it was lean. I then bought DEK and EEK needles to riched it up. I tryed both needles in all clip positions but it still has a sputter. The best it seems to run is with the EEK with the clip at the bottom to make it all the way rich. I doesn't seem to be popping now so I think I am going in the right direction... I think... oh and one other thing is, it runs way better when it's cold, the hotter it gets the more it sputters... don't know if that means anything. So I think I have to go to a richer needle yet... I'm just not sure where to make it richer... taper angle or length... I don't mind buying more needles... they're cheap... but they take about a week to get. Right now I am thinking of getting a ECK, which is shorter... or maybe a FEJ, which has more taper angle... Sudco's chart doesn't have an F taper in a K diameter. :shrug: If anyone has any suggestions that would be great...
