blue-banshee Posted August 1, 2011 Report Share Posted August 1, 2011 Hey guys havent been on in a long time but i just bought another banshee and i need some help, that guy had dual kenith pj's on it set up with stock pipes and aftermarket slincers, the bike didnt run worth shit, so i took the carbs apart first the one air/fuel mixture screw was missing and there is differnt jetting in both the one has a 145 main and the other has a 175 main ? that cant be right? also the piolts are diffrent couldnt make out what they where though. anyway i was just wondering what a good base line to get thing thing going would be? anyhelp would be awsome i wanna rip lol. also has no air box just k&n clamp on's -Stock pipes --K&N clamp on's -kenith PJ's -Pro desing intake and "boost bottel" Quote Link to comment Share on other sites More sharing options...

sangheraent Posted August 1, 2011 Report Share Posted August 1, 2011 I got 162s on my 34pjs. I got a 4mill stroker 190psi toomey T5s, Pods, agressive trail port, Vfroce 3 reeds. On a stock motor with stock pipes your carbs are way too big. the 145 is probably right. the other one is probably jetted for the airleak. order an air/screw mixture.

jbooker82 Posted August 1, 2011 Report Share Posted August 1, 2011 I woudlnt have a clue for stock pipes and porting. I ran 162 to 165 mains, CEK needles middle clip, 55 pilots when I had a ported 350 with pods, and FMF SST's and T5's. I now run PWK's because I got tired of messing with the idle speed / choak nobs. The pj's needed larger pilots than the pwk's. I think that is because they are not as efficiant at pulling fuel up from the bowls and atomizing it.

SandmanPNW Posted August 1, 2011 Report Share Posted August 1, 2011 I woudlnt have a clue for stock pipes and porting. I ran 162 to 165 mains, CEK needles middle clip CEK? I thought there were CEL or DEK? Is that a hybrid jet? Quote Link to comment Share on other sites More sharing options...
camatv Posted August 1, 2011 Report Share Posted August 1, 2011 pj's have a differnt idle air circuit than pwk's it's part of the whole retarded idle screw/ choke knob thinngy. Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted August 1, 2011 Report Share Posted August 1, 2011 CEK? I thought there were CEL or DEK? Is that a hybrid jet? There are 50+ different needles you can run in keihin carbs. First letter is the taper angle, middle letter is the length, last letter is the diameter. CEK and a CEL have the same taper and lenght but different diamters. The diameter controls the amount of fuel in the 1/4 throttle area. As you work your way down the alphabet they get leaner in the 1/4 throttle range. So the CEK is a little more rich in the 1/4 throttle range vs a CEL. Quote Link to comment Share on other sites More sharing options...
blue-banshee Posted August 1, 2011 Author Report Share Posted August 1, 2011 Okay guys thanks im think im gonna go with 145 mains and try that, and also look for an air leak, couldn't see one when i was looking at the other day but its got a dumb ass boost bottle some im sure its leaking from that where its going into the intake. how do i figure out what size of carbs i have? just measure them?

blue-banshee Posted August 2, 2011 Author Report Share Posted August 2, 2011 Turns out there 34 mm carbs will they not work at all with my set up? i think im gonna go buy the air screw and another 145 main and try that unless some one thinks thats not gonna work/bad idea. or should i just be looking for a set of stockers?

Its not that they wont work they are just not Ideal. They are a pretty large carb for a stock motor / stock piped banshee. I would look for a set of Keihin PWK 28mm carbs. They are much better than the stock carbs and wouldnt be to large for your setup. Their are people on here who run the knock off OKO 30mm carbs but I wouldn't. A junk carb can cause way to much head ache for me so that is why I would stick with genuine Keihin carbs. Quote Link to comment Share on other sites More sharing options...

That and any mains you buy for the PJ's should be the same for the PWK's. Quote Link to comment Share on other sites More sharing options...
blue-banshee Posted August 3, 2011 Author Report Share Posted August 3, 2011 okay did the jetting today thats all good, but now ive got some bigger issues, the bike smokes a ton out of the right cylinder and feels like its not firing on the left its not a carb issue because i switched them from right to left no difference, also not a tors issue dont have that, not spark either because i switched plug wires and no change from cylinder to cylinder. so im thinking the worst maybe a dead cylinder? i took the pipe off and looked up there the bore looks good and from what i can see of the piston it looks alright to. so im clue less. its got me stumped. Im thinking maybe not enough compression? when the bike does get running and you ring it out a bit the left side back fires and you can see flames from the back of the carb. also its pretty hard starting anyway now you know as much as me. im totally lost maybe one of you guys has an idea.

Larry's Shee Posted August 3, 2011 Report Share Posted August 3, 2011 Excess smoke out right side is probably bad crank seal sucking trans oil. Do leakdown test to confirm. Not real sure about left side issue. Could be bad reeds or leaking seal on left. What's left plug look like? Check that flywheel is tight and pick-up gap is good.
