2006 Kawasaki Prairie 700 Rear Carb Leaking out the side , not bowl overflow

[Venom]

Hi All,

Hoping someone will be able to help.

I have a 2006 Kawasaki Prairie 700 with twin Keihin Carbs CKVR D32. The Rear Carb is leaking out the side during cranking. it is not the float bowl overflow. It is on the opposite side of the carb from the diaphragm. 

I got this bike not running and someone had already messed with it. I took the carbs apart , cleaned and rebuilt. Everything went pretty easy.  It looks like it could be missing a small tube between the carbs but I have all of them listed in the service manual installed. See the pic for where it is leaking from...

Any help would be much appreciated.. Thanks.

Have you looked on the other side of the carburetor to see if there’s a brass plug ? 

My guess is if someone was tinkering around with it then maybe something was removed.

I'm thinking wrong routing of hoses or could very well be missing hoses.

Ok, I took it completely apart. that hole looked sealed. I blew in it and it is sealed. The only other place gas could come from would be the pass through tube just above it. I took out the pass through tube and looked at it under a magnifying lamp... There it was... A small crack in the o-ring. I put new o-rings on it and put it back in. That fixed it... it was leaking down onto that other opening that made it look like it was coming from there...

Good find.
