Hello. This is my first post. I searched for other posts about this but i couldn't find anything. I have a 2000 yz426f. The O ring/wire mod was done, and it completely eliminated the yamabog. Awhile later the bike was running great, then one time I cranked on the throttle and it bogged out. I pushed the bike home, started it and it ran. It still bogged out. I know the problem is with the ac pump because when I twist the throttle slowly it revs up but when I let off it drips/dumps fuel out where the push rod comes through the carb and meets with the black actuator arm. I know a seal or gasket is bad i just don't know which one or what caused this. When the carburetor is off the bike, the stream of gas that is sprayed when you twist the throttle isn't a nice steady stream anymore, almost like there is a little bit of air coming out with the fuel being sprayed. Any help would be appreciated thanks.
