Keihin PWK Carb No.

[randy2112]

I want to know whitch carb I have, It is a PWK and I think it might be a "AirStriker" but dont know...
Here are the markings:
PWK
Keihin
g095 aih8
It has 4 vents and the 2 fins around the needle jet.
Inlet is 3.18"
Outlet is 1.63"
If anyone can point me to a tuning guide also that would be great.
I am legally blind and cant figure out how the needle is removed from the slide.

Thanks

those numbers don't match to anything. look for numbers like 72r,73r,70r etc.somewhere on the body of carb or possibly the numbers 29s,s46,s66 etc.

Thanks, I will have someone look. If I am running a 310 main jet in the Mikuni would I start with a 310 in the Keihin? Or are they totaly different numbering systems?
Oh yeah, I figured out the needle jet...

the numbers from a mikuni to keihin are diff. i've seen just a general cross reference between the 2 carb brands i'll see if i can find it and post it here.

Thanks, But I am still confused! LOL Flotek posted up that a guy needed a 165 for a Keihin PWK when he was running a 370 in a stock Mikuni.
Thanks

 

[244blackblastard]

opps sorry i posted the wrong chart.

 

[randy2112]

Oh, O.K. Thanks anyway.

 

[244blackblastard]

can't find it right now but depends what carb your using. kiehin ,mikuni brands depending what carb it is have all different jets. some brands/jets rate on flow and some go by the actual hole measurement. when you do a cross reference it depends on what style the main jets are. only way to know is what carb you have and what carb your trying to cross too to get in the general ball park but then it is still hard because different carbs work diff how it meters fuel and also depends on altitude(sea level) that's why you do plug chops to figure out if your running lean or rich for your riding area.

Thanks I just need a starting point so I don't fry my new engine. I asked the guy doing the port work, Hopefully he will have a idea of where to start. Thanks again.
