i know there are at least 5 people here who are running or trying to run the keihin 34mm pj. either if your running duels or single post here. has anyone succesfully got there engine to idel and run good with these carbs? is there any trick? its either really fussy or they just aint ment to run on the the banshee. because i cant get mine working right. though i havent spent too much time with mine, i would like to know if its even possable.

Mine idle just fine, just turn them out counter clockwise 7 1/2 turns like Banchetta stated. I just turn mine out by clicks and i think im out about 30 clicks...

i dunno maybe its just my ill jetting skills. but ideling the engine isnt so good. i got .02 shaved head, lightend flywheel, advanced timming +3, 2-1 cv intake with 34mm pj.

 

im gonna keep messin with it for now. 7.5 turn seems like a lot. and you guys seem to think about 4 turns or so on the air screws?

 

if i had a choice i would buy the pwk's but... ill figure it out eventually. about the one who is buying the 34's i heard thay dont even make them anymore they stoped in 2000 or 2001. i dont know if thats right or not. people seem to have problems with ideling them thou.

Check duncanracing.com, they have easy to follow jetting info. sounds like your piolet jet is wrong. Good luck.

mine runs fine.

Adjust your air screws to the best throttle response and let me know how many turns out from seated they are....You should be between .5-3 turns from seated, but let me know where your shee likes the settings..

The only way to get pj's to idle is to turn up the choke a bit.(the nut at the base of the choke knob) I run two 34's. They are great carbs, but the idle issue seems to be a bit of a downer. I run em' with the choke completely off. I just can't seem to get over the mental stress of running my Banshee under a slight rich condition. Yeah, I won't idle more than a couple of seconds, but my jetting is spot-on, and it runs great across the throttle.

Off topic a bit, but do you guys have much bottom end with your 34mm PJs. I bought an 88' with them on it and I think it also has the old school fmf pipes and I don't have hardly any bottom end. I assume that it has some porting due to the larger carbs, but I don't know for sure.

Its a matter of jetting, porting, pipes, and the combination of it all will give you great throttle response....Tooo big of a carb w/ no porting will cause poor response, so you need to find out what you have.

I am running 2 34mm PJ's on my bike. Setting the idle was a little tricky. I had to turn them out 21 clicks. I port and polished my bike when i put the PJ's on. I did lose some bottom end, but mid range and top end are great! I have a coolhead with 19cc domes toomey T5's, +4 timing, dual K&N's.

You shouldn't have to turn out your idle that much. Your pilots are way off. I'm guessing your too rich on the pilots. How does it start when cold? w/ or w/o the choke? How does it start when warm? Does the air screws like to be .5 turn out or 2 turns out? (throttle response)
