I f you are having problem with this carb at topend seem to be running out of gas an sputring I have found out through who is at HPD all the time helping test stuff. He was haveing this problem an so was my friend. Daryle at HPD has figured out the problem there is a brass pin in the bottom of the float bowl. This pin is stoping the float short an makes it starve for gas at wid open. The fix is to remove the pin pull it out is what I was told to do to my friends an will fix the problem well hope this helps you out there

 

This information is correct .

not sure what you mean on this brass pin?

 

Take the bowl off of the carb,hold it in your hand .If it has a brass rod sticking out of the bowl,take some pliers and pull it out.If you don't have a brass rod in the bowl,you are ok.

 

wich one? i got them both,the pwk HPD sell is not the new design "race only" carb and don't have that problem,but the older i bought from them
was doing the same thing at wide open,the newer pwk is a lot more efficient with a pre-otimized vent tube through the float bowl,at 170 main jet plug is perfect tan brown even on the rich side.i bought
the newer version from keihin themself.

 

i will have to look for sure but what if it does not have the brass piece and still sputters? well i seen this thing that was about 1'' long that was on the bowl side kinda looks like rounded top with a pin? well i hope that was it as i RIPPPPED it out but that was all i seen in there now i need to test cant wait

 

Would this affect the float level as well? I've had hell with gas sloshing out of the bowl overflow vent. I've adjusted it till blue in the face. I've gotten it somewhat better but still have some spilling out but not as much.

Thanks, X Scram rider. This is what this forum is about. Letting others know things like this.

 

I was told to do this a while ago so I did. As soon as i turned the gas on it just poured out of an overflow hose.

 

123, is your carb the newer one? I got mine last year, and the first thing I did was took the bowl off, and clamped a pair of vice grips on the "brass rod". But then I looked at it some more, and realized that I was fixn 2 pull out the over flow tube.

 

i'm mnot sure if its the newer one or not, but if that was my overflow tube that would explain the leaking.
