    Engine Trouble Cylinder coating question

    Can anyone tell me whats going on here what is that residue on the cylinder ,also is this cylinder coated, and if it is how thick is it, can it be bored to remove the old coating and re-coated ?, its a Kawasaki cylinder from the 70s , were they originally coated from the factory ?

    ceramic outside coating?

    does the coating keep the heat in or let it out faster if in that is why you get a lower reading when checking the cly temp. but internal temps would be more not less I have to laugh how many give advice that don't know what they are talking about
