Well, looks like WUN lost that bet...

    I finally got around to ripping apart the engine of the first Motosport
    I bought a few years back - the one that "just needed the electrics
    hooking up" before it would run. Which it never did, despite having a
    spark and fuel. And kicking over a lot easier than the decent one I
    acquired later on.

    Head came off without too much fuss (well, once I found the hidden nut
    that held the whole thing on after I was sure that I had removed all of
    them...). I'm pretty sure the engine's not been opened by the previous
    "restorer", given that everything was painted over in what looked like
    silver Hammerite. Head is not looking too bad, some light scoring on the
    cam journals but "good enough for ebay".

    And yes, WUN, there is a piston in the engine. And some seizure marks on
    in the barrel, plus some rusty water marks. Unfortunately the plonker
    who "painted" the engine painted over an already seized in fastener so I
    can't take the barrel off until I ground off that bolt
    head. Great. Especially great because it's one of those cheesehead
    bolts, and Mr Honda put it into a location where you can't get a ring
    spanner on it. So that looks like Dremel or angle grinder time, and at
    the moment I haven't got either...

    I'll use a few parts on my 'good' Motosport and the rest goes on ebay or
    the bin - engine parts for these seem to be fairly sought after.

    Oh well, and I thought I'd manage to strip the whole thing in an
    afternoon. Yeah, right.

    Try the hot spanner.

    I will, even if it's just to burn the paint off around the fastener and
    hopefully loosen it a little.

    Get it nice and toasty, wire brush the paint, reheat red, squirt plenty of
    oil. This will a) make smoke and b) suck oil into the threads as it cools.
    Have an extinguiser ready justin case.
    When it cools tighten slightly to help break the seal before loosening.

    If this fails heat it up again and chisel the damn thing off, you have
    nothing to lose at this point.
