hello no i didnt get the pistons out .. like i said its my first project so onley the heads ported and new cam .. and clean up everything.. if you feel on the edge of the cylinder wall you can feel a little ridge on it .. but onley the dark ridge .. its not much and by looking the piston isnt touching it at all..
i looked a few days ago on the internet and I found a few pages that says that an interference fringe an accepted phenomenon .. but what will happen when I let it sit there is not a scratch or feel visible in the cylinder wall .. there was on that edge a little black attack like the pistons .. I HBE and edge gently cleaned the pistons also schooingeborsteld .. I have the pistons leave because this is my first project and I still do not know everything and I piston rings and bearings risky find ..
mn engine has basically always nice run. but had a leaky koppaking. and did only what cylinder machining done and everything cleaned e camshaft replacement for others
