What the hell is this?

or this?

I make a start on the left hand cylinder and one of the studs comes right out. I'm pleased. It looks like this. Yay! It's not been apart before.

Joy is short lived when I go round the other side. Looks ominous. Chisel marks below the intake and lots of goop.

And there's only three nuts holding the right hand cylinder down. Huh? Ah - this could be why. Stud fitted upside down.

Now I'm no expert but I don't think this is a proper Kawasaki cylinder stud:

Oh boy. Where do you start?


But weirdly a new genuine standard piston in centre. Not that it would have lasted long with the oilways being totally gooped up.

Poor wee thing!
