PJ I am dealing with a repeat problem on one of my Super Zs. It has the 25 Kaw on it and it leaks from under the top cover. I have had it fixed by Pro Mower and myself. It has less than 100 hours since repaired by dealer and is leaking again. The machine one has just over 600 hours total. Mike said this may be an ongoing problem with this engine. Have you seen more of this? I can't justify repairing the same problem twice a year. Do you know if Kawaski is doing anything?
