Keihin PWK carb experts?

[Milhaus]

Trying to figure out what carb I have i.e. bore dia. and what jets are original as the bike seems to have a mix of stuff on it.
Its leaking quite a bit of fuel from the "overflow" tube.
marked with V790 QJ13

Thanks in advance

What year and make is the bike it's on?

Sorry Its a 93 KX125...but I wouldnt assume its the orig. carb,

Sounds like you'll need to adjust your float level to get rid of the overflow situation (fuel level too high). Also check to see that your needle and seat assembly is sealing properly.

Thanks guys.Rhodester, I just adjusted the float according to the manuals specs and instruction. The float needle tip looks fine, but how do I know if its sealing properly?
Interestingly John, my main jet is a 168. Could this be why I'm running pig rich i.e. pipe full of oil? What jet should I try now considering I also have carbon fiber reeds, pro circuit pipe?
Sorry for all these questions, but I didnt get a lot of info from the guy I bought the bike from, and I've never been good around carburetion (cant wait till fuel infection hits the dirt masses).

Its hard to say without a wot plug chop. The main jet is mostly for 3/4 to full throttle. Maybe your rich on your pilot and needle. Unless you rider wide open alot. :ride: :laugh:
