Water

[Mike52]

I am working on a later model 4/s Kawasaki and the owner has left it out in the weather with the top off.
It had an inlet insert falling to bits which is something I have never seen before.
Fixed it all up and started it only to find that it had water hidden away somewhere  :'(

Anyhow what do I wash the crap out of the motor with.

I would use some diesel and if you are talking about in the motor 4 stroke. diesel and oil give it a run then drop it out.
