Hi everyone. I recently bought a 92 750ss and I'm experiencing some frustrating issues. I put it in the water and it runs like a bat outta hell for 30 minutes to an hour then goes into limp mode. I felt the exhaust manifold an head an they were at normal temp. Brought home and flushed cooling system to he safe and took it back out and same thing happened. So I bypassed the temperature safety switch to see if it was a fault switch and it still went into limp mode. Not sure where else to go with this please help.

 

Update... Was talking to a Kawasaki Tech and he said the symptoms that I have is most likely a bad check valve on the vent tube from the gas tank. Replacing the check valve this weekend an will update when done
