    Worth hanging on to for the future. A lot of the internals I've had in old British engine restos have been far, far worse than that to begin with and have come up fine.

    Reminder to myself, never store bike below the high tide mark...
    Nice work saving that one...

    I don't know how or where it was stored, but there was zero oil in the engine.
    Apparently it had sat somewhere for over 20 years unused.
    I have opened up engines that had sat for decades unused but because they had a coating of oil over the internals no rust or damage followed.

    It looks more like condensation rust than immersion damage, so it has probably been left out in the snow for years. If there wasn't any oil, do you know why it was parked in the first place?

    No, I was told the motor was freshly built then left in storage for decades.
    I find that hard to believe as there was a lot of carbon build up on the piston crowns and combustion chambers.
    All I know for sure is it had no oil in it and it had been stored extremely badly.

    Is that the recognised way to instal the triple motor?
    Because my motor had been a complete mess, I had it completely together, laid it on its side then lowered the bare frame on to it. Both seemed surprisingly heavy at the time.

    If I have a bare frame I have often lifted the frame over the engine on it's side.
    Easy once you get the knack and literally can take 20 seconds to do unassisted.
    But it is not practical to totally strip down a bike just to fit or remove an engine if it is only in for engine work.
    So, the engine hoist is used.
    I used to manhandle it into position with a friend but there is more risk of scratches to the paint even with foam pipe lagging and rubber caps over the exhaust studs.
    It was my first time lifting an engine back into a frame using the engine hoist but I have removed a couple with it. Only bought it recently as I wanted to make the bike work less labour-intensive and heavy lifting is not best in the long run.

    The rubbers on the exhaust studs are a great idea, they bite hard. Its a bad hand lift on your back.Been there too often.Looking great as usual Grant

    Aye, they gouge deep and very easily.
    The engine isn't that much, around 70kg I think, but it's awkward to get hand holds and easy to crush digits. (and pop discs).

    I bought my Mirage in parts. The engine was finished first, only the head was ruined.
    The bike had been torched so the frame took longer to source all the smaller bits that were destroyed.
    After trying to lift the engine and manoeuvrer it on my own, the laydown method was the only way to do it (outside in my front garden).

    Working at Dunlop, we used bits of rubber tube over threads and studs all the time.

    So what was the story behind that 1200 engine? Had someone left it outside for 30 years?

    Maybe my fault for flicking back and forth between different bikes as I waited on progress with 007.
    007 arrived to me as bare frame, bare crankcases and a rusty crank.
    The destroyed engine I showed earlier wasn't for this bike.

    I built all of 007 from spares I had accumulated and a donor bike that gave up it's wheels, forks, yokes and instruments.
    This is what I started with:

    Fitted exhaust system today and chain guard, then moved it into storage for a week or so as I have big plans in the coming week for the workshop.

    The green bike is for sale too by the way.

    The valve cover is so clean looking ... I mean there are no bolts, apparently. How is held in place?
    I was curious too about the bottom races for the camshaft - I guess they're bolted in with the tops and camshaft itself.

    I really like the shape of the green tank. Is it the same as the red but looking different due to missing graphics? The Laverda badge is nice!

    The cam box cover is highly polished as standard. It's secured by 6 Allen screws to the cam bearings.
    I'm still waiting on new cam bearings arriving so the cam cover is just sitting in place to keep dust and small children out.
    The cam bearings are separate from the head and can easily be replaced.
    They are secured by 6 through bolts from crankcase to head. The end ones slide onto the camshafts, the middle 2 are split.

    The green tank is an early 3CL style tank with round badge recesses.
    The red one is a completely different style (but interchangeable) for an early 1200.
    Later 3CL and 1200 tanks had no recess and used a rectangular badge.

    Today's update was unexpected.
    Got made an offer I couldn't refuse and the bike is now sold pending completion.
    The deposit will help me to finish it off quicker than fitting it in around other jobs.
    I will still document the build, but once finished I have another project in mind and that one will be wild.

    Do you include your rebuild blog with the sale? Seems like a buyer would appreciate having it, you know, it's part of the bike's provenance. :-)

    Of course I do.
    The owner or buyer receives regular updates with plenty of photos.
    Several visit a few times over the course of the build too.

    The new cam bearings arrived today.
    Pure bike porn.

    The reason I'm not working on the bikes at the moment is that I have a new wee project in hand.
    Installing 3-phase power and building a couple of rooms for the vapour blaster, compressor and polishing wheel.
    Hope to get it done in about a week.
    Started installing the 3-phase cabling today. Yesterday I scored some great wood as a friend was having a decking removed. This will give me a help in keeping costs down.
