carburetor help


Recommended Posts

Alright guys, another question on my "can't get right banshee."

 

34mm pwk single keihin

175 main jet

42 pilot jet with air screw 1.5 out (air screw has no effect)

#6 needle jet and not sure of position, can't figure out how to adjust it.

sea level is 550-650 ft and its hot as hell outside

 

Banshee won't idle and idle screw has no effect. Powerband is virtually doesn't exist in 1-3rd gear but when i hit fourth it has all the power in the world. Im starting to wonder if my pipes are causing this or if the carburetor is just a flat out piece of shit. And if anyone has any clue whatsoever, let me know. Its driving me crazy.

 

Also, if anyone has any stock twin mikunis for around $100, let me know.

try a 50 pilot, and your main is too big. should be around 150ish.

 

and what needle are you using? never heard of a #6

 

 

well i changed out the main. the guy had a 200 main in it and i read that i needed around 170. As for the needle jet, thats what it said on the slide valve. Im not too familiar with these types of carbs.

take out the needle and see what it says on the side. and also what clip it is on.

the #6 isn't really useful info.

 

and 170 is still big for a 34mm carb when it is 90F out.

 

Well i looked at it and i don't see how it comes out. I know how to do it on the mikunis but not on this one. Should i buy a 150-160 or 145-155 main jet.
