    Got the handlebar fairing, mudguard etc for the blue bike back from the painter and rebuilt.

    The laser welded crank cases for 007 were finally collected from Germany yesterday, so they should be here next week. That build will take priority over the blue bike. The blue one is for me and the 1200 is to be sold when ready. I was going to keep it but decided it was too samey with my own bike. The blue one has a 120 degree crank, left foot shift and more relaxed ergonomics compared to my own 180 bike so it will complement it better.

    At last!
    007's cases arrived this afternoon.
    I'm pretty pleased with the laser weld repairs.
    The cracked upper rear engine mount is solid, the hole where the chain punched through the upper half has been filled, and new bottom engine mount lugs fabricated and laser welded in place.
    Still waiting on the barrels and pistons to come but at least I can start the bottom end rebuild when I find the time.

    Had a run out on a bike I just finished. Some running-in miles before first service and re-torque the head.
    Difficult job but somebody has to do it.

    It's great that the case could be saved with the laser welding.

    Yes. I have another case to try to save.
    Cracked cross the main bearing seat, previous bodged weld that seems to have cracked again.
    Further complicated due to being an oilway as well.
    Will send it off next week.

    Must have run very badly. Co-incidentally, or not, the small end bush literally fell out of the conrod at this cylinder.

    They are incredibly tough engines and can stand dogs abuse but some DPOs seem hell bent on torturing them.

    By the way, this leetle beauty turned up today. Very cute and very rare.

    One of 6 second series Formula 500 imported into the UK by Slater Bros (the UK importer at the time).
    Has forged pistons and a close ratio box (60mph in first).
    First series had one piece tank/seat and second series had them separate.
    Original Menani clip-ons, almost zero steering lock.

    I've always thought that Laverda built very attractive roadsters, which get completely overshadowed by their more sporty cousins. The 500cc models are quite rare, I can't remember the last time I saw one. That's a nice example, with a non-stock paint job and indicators I believe?

    Should have a black frame and there were various colour options on the bodywork. I have seen black, light blue and red, maybe more but the Alzheimers light is kicking in.
    Apart from the very first batch of Montjuics they were all pretty much the same spec internally as the Alpino.
    First batch had a close ratio gearbox and forged pistons from the Formula 500.
    Main differences for the Montjuic vs Alpino were the straight through Sito exhaust system, no airbox and carb internal changes, oh and the fibreglass handlebar fairing and seat unit.
    The Formula 500 is a rare beast, and becoming very sought after these days. The factory ran a one make race with only Formula 500s in Italy.

    From my experience, the brand does not matter. Torture/abuse is mandatory for alot of PO's.

    Back on the blue bike engine again (project Phoenix).
    Some parts arrived today that allowed me to do some more on the engine.
    Fitted new spacer and circlip to the clutch drum, fitted the primary drive sprockets and Duplex chain. Better and quieter than the previous Triplex chain fitted as standard, as this is a Mercedes timing chain.
    Then the outrigger bearing and support, and finally the primary chain casing and tensioner blade.
    Next will be to fit the alternator assembly on the other side but then things will slow down as I'm still waiting on the cylinders/pistons and I need to save up to get the damaged head (smashed guide, broken valve, damaged combustion chamber, buckled cam bucket and potentially bent camshaft) repaired.
    Poco a poco.
