RACxEMxWILLIE Posted July 3, 2012 Report Share Posted July 3, 2012 Does anyone know how hard it would be to convert my 2-1 keihin stage 4 setup to the stock twin carbs. This includes everything involved with the stock carb setup (air box, boots from intake to carb, carbs, boots to intake, and throttle cables). Would this be a pain in the ass to convert over? I ask because the carb i have now is a 34mm pwk keihin and I'm beginning to believe its way too big for a stock engine. Any suggestions or if anyone has an old set of carbs with all the bolts, boots and air box, list your price in a pm. Thanks guys! Quote Link to comment Share on other sites More sharing options...
Dahl87banshee Posted July 3, 2012 Report Share Posted July 3, 2012 What kind of 2-1 intake do you have? Maybe we could trade Quote Link to comment Share on other sites More sharing options...

RACxEMxWILLIE Posted July 3, 2012 Author Report Share Posted July 3, 2012 I ask because my setup seems to be getting too much fuel, it shoots out blue smoke even after its warm, still a little boggy before power band and it won't idle right after i re-jetted it. Im running 4:1 fuel. Im beginning to think that theres a leak on the boot that connects it to the intake. Looking for a new boot and neoprene fuel hose from the petcock. Also, the guy i bought this thing from fucked up the air box and I'm having a hard time finding one on ebay. Quote Link to comment Share on other sites More sharing options...

Dahl87banshee Posted July 3, 2012 Report Share Posted July 3, 2012 Yeah I didn't read the stage 4. I'll have to pass. I may have been interested if it was one that performs a little better. Post some pics though of the whole setup I'm sure someone will be interested in it. Quote Link to comment Share on other sites More sharing options...
RACxEMxWILLIE Posted July 3, 2012 Author Report Share Posted July 3, 2012 what is your jetting currently at? also what needle are you running? The main jet is a 175 and 48 pilot. Not sure about the needle. Air screw is 2 1/2 turns out and the idle screw is all the way in. You have to tap the throttle for it to crank and when you let go, it dies. Also, its not really responsive when in neutral when you rev it. I absolutely hate this carb but its the one it came on it. The guy that previously own it was an absolute dumbass.

registered user Posted July 3, 2012 Report Share Posted July 3, 2012 sounds like your just 1-3 sizes large on the pilot. with the a/s 2.5 out and it wont idle generally that means you should drop it down. not sure if your familiar with the pj but every pwk ive used needs several sizes smaller pilot than pj Quote Link to comment Share on other sites More sharing options...

registered user Posted July 4, 2012 Report Share Posted July 4, 2012 seems like you mentioned a 48 in there now. most likely your not far off thats why i mentioned drop 1-3 sizes. if it was my bike i would throw in a 42 and see what happens. got several bikes with pwk and one is using a 40 and the other 45 and have another bike with pwk but cant recall the pilot size. probly around 42. if its a newer carb with the plastic idle screw they usually put loctite crap on the threads at the factory. make sure you can turn the screw all the way in because that stuff on the threads is so it dont vibrate out but some people get confused when the screw gets tight about half way in and they think it wont go in no further but it does Quote Link to comment Share on other sites More sharing options...
