Hi I have a Kawasaki GPz 550 1989 (ZX 550) and I have K n N air filters on it and every time I run the engine and open the throttle and turn the engine off, the fuel keeps on leaking from one of the air filters my local motor dealer said it might be the jet sticking or dirty, I'm just asking whether anyone else has had the same problem and what can be done to solve it thanks marc.
