Phone a Ducati dealer with the engine number, if you ask nice they might find what it came out of. (Ducati Manchester did this with my frame number so I could get Badger's reg and V5)

If it's not what was advertised take it back and get your money back.

Buy mine with the recouped cash.
Easy!

I am tempted to buy your engine; but on one level buying your winnng engine would create a sense of expectation and keeping this engine is easier than taking it back to Epsom.
I did try my friendly Ducati dealer (Seastar superbikes)they only work of frame numbers and not engine numbers.

Can people let me know their valve clearance on openers and closers please and state if its in inch or mm........ thanks in advance.

Thanks Kev,
what is the significance of the left and right column? Is it hot and cold engine?

go with left column cold- forget the right- easiest way to adjust them is with head off then you can lap them in with grinding paste before you set them- also you can spin cam with opening rockers pushed out of way and check cam turns free without dragging on closers- california cycleworks vid "valve adjusting on ducati 2valve" on youtube makes all very clear

Thanks for the heads up. I have now dismantled the engine and I am currently lapping the valves in before taking the heads to a ducati man on Friday who will sort the shims out for me.
I have spotted that the engine barrels are from different engines and the lower one has been re bored. I can still even see the honing marks. Its strange that this lower piston had the low pressure. The piston, rings and valves seem ok; but the vertical piston with all the pressure hasn't been rebored and both valves seats were ropey; has this all been in vain?
Maybe it wss the pies and guiness al along?

on the Left we have what Ducati recommend you set them to and on the right the tolerance
