    @calum oh now that you say it I remember.
    I mean I would not be surprised if my previous piston has expanded a bit too much in the cylinder.

    As you can see on the link there is like a mirror finish in the exhaust and inlet side. I don't have a clue where the ticking/rattling sound came from though.

    @irongamer727 Sounds more like glazed bore which is due to incorrect run in procedure.

    I've switched from Wossner now, after PJME have advised they've started manufacturing their stuff in China.

    Now China has some of the worlds foremost engineering plants in the world. It's their QC that lets them down.

    I've now switched.

          @calum is that cylinder scrap? The piston was 58.4 mm. So I guess it is soon no point boring that cylinder? Not that I will use it again.

            @irongamer727 You can go overbore. Really need to modify the valve when you do. And you can have a new liner put in.
