I own a 1991 KDX 200 with which I am really pleased with its performance. Recently, I got the bike out to ride and found fuel to be leaking from the bowl vent. I disassembled the carburetor and checked the float height and it was ok. I suspect the choke valve but cannot be sure. I checked the float for leaks by submerging it in a container of water for several hours to see if it would sink. The bike has a FMF Fatty pipe with the big legal spark arrestor, Boyesen Power Reeds and I'm currently running a 158 main jet. I've also replaced the needle all to no avail. Still loading up with fuel to the point if I do get the bike to run, raw fuel blows out the pipe on startup. Any suggestions or recommendations as to who I might send the carb to for repair. Would I be better off replacing the carb altogether? Thanks for any help!!
