    Cheers guys!

    So, I can't put it off any longer, I've started cleaning up the engine. I don't interned stripping it all down at this point in time and having it vapour blasted. It does have to have the clutch side off to fit the new generater but I'll give it deep clean with good old petrol, a tooth brush and green scourer first.

    It comes apart real easy because Ducati screwed it together with Allan bolts back at the factory

    But what a mess!

    Three hours later and it's looking much better. I've only done this side but It's coming up much better than I expected, the quality of the alloy is very good, much like BMW alloy was before the 1100 oil heads.

    Quite a way to go yet, but if I get it as clean as I can then add some shiny new allan bolts I might just be able to fool the public (from a distance)

    That looks a fun job

    They really are (well to my eyes anyway) such beautiful looking engines

    You may want to rethink that.
    Andys engine was in a right state,mind you,it did turn up in a box
    That said,in 30 or 40 years who knows what’s been messed with.
    I’d like to think we have seen it all but ,,,,,,
    For the cost of gaskets and seals ,to me,it’s a no brainer.
    If all is good inside just clean it and rebuild it.
    If there is a horror lurking it’s got to be better to address it now than have a trashed motor

    Not wanting to worry you unduly, but the roller big ends can and do go bang. I have personal experience of such a mishap while travelling at some speed. Stayed upright fortunately. It can be difficult to 'feel' for play. Crank has to be separated to check/replace. I had Alpha Bearings rebuild a crank with new rod and bearing. The price was reasonable, but it was some years ago. There's a sludge trap in the crank that requires cleaning too.

    Cheer's Paradiso, I had heard of the sludge trap, If I stripped the engine down it would at least be done with. I'll think on it.

    PS, the head light mounts have been swapped over

    I've made two new clipon extenders as the old ones below are kaput (loose fit and one has a hole from a previously fitted bar end mirror).
    You can probably work out from the picture how they work, The 6mm expanding bolts are a cheat but I didn't know a way to cut a suitable tapered hole in the alloy.
    Anyway, they look good and know one knows but us, OK

    They used to say the engines were more shiny inside than out - and it's true!

    Keep 'em going-
