2003-GS500, I have installed Honda CRF petcock (which has separate res and normal lines) from past 8 months and bike has been running finpe. (With vacuum-fuel line blocked).

From yesterday, bike has been dripping from right side carb and my only solution is to run it on res only fuel and put it to on so that it doesn't drain the whole tank. Pictures attached as I inspected after removing air box.

Bike feels like it's running too rich suddenly with frequent shutdowns at low rpm. No loss off power during accelerating though.

What can be the solution please?

A few possibilities: stuck float, sometimes dirt, sometimes corrosion, sometimes lousy fit of after market needle.

Also, inspect the operation of the float thru the entire range;
the screw that locks the float pin gets pretty close to
the float tang, potential to hang up the float.

Thank you for replying.

I found out that right side carb got its mixture screw fell out. There is only rubber O ring left in there. Time to shop for a mixture screw kit. I guess all the CV carbs have same mixture screw kit if the V shaped wedge and pitch matches.
