    Happy days, long may it run and welcome to the elite proper job 'man made in shed' fixer upper club.

    I did my first engine strip and rebuild half a century ago. I bought a 22,000 miler '74 Cortina 1600 XL for peanuts with a failed camshaft. Full strip included re-honing of the cylinder bores, over size piston rings, replacement camshaft, 'man made in shed' modified camshaft oil feed pipe and then some. Me and my father used it for mini cab and courier work before I sold it for more than it cost me 150,000 miles later!. Like most previously owned motor vehicles I wish I still had it.

    Hey, they don't make cars like they used to, thank god. Back in the day 100k miles was astronomical, now it's an expectation. My 2014 Mini has 130k on it already.
    I can't claim to be doing much of anything 'half a century ago' Action Man was still my thing in those halcyon days of my yoof.

    It was the difference in hand assembled with care on mum's kitchen table vs a Dagenham production line

    Some pics from the stripdown;
    Showing the broken head gasket
    The bore of cylinder #3
    Transmission comes out as a cassette, bonus
    With as much removed from the engine as possible it was easily lifted from the frame

    The first two photos are gruesome!

    Thankfully that was the extent of the initial engine damage

    What a good read Keith, I love the way you work through the (bloody hell) issues.
    I only ever had to rebuild a 2 stroke that I got as a project back in the day a Suzuki GT 750.

    Thank you, I definitely get the impression the CBF engine is generally a tough old beast.
