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?

the tolerance/ service limit given always seemed so wildly out to me seems better to keep them closer than that- 0.05 and 0.2 seem a world apart??

I took my pistons, rings, barrels and heads to a local "ish" Ducati Ninja to cast his eye over and shim my valves that I had previously lapped in.
He said that everything was good now the shims hasd been done as there was no gap on the inlet valves and the rest of the engine was in fine shape.
He patiently listened to my perceived lack of acceleration problem, looked me up and down and said "lose some weight fat lad", the other option is to throw more money at it and adjust the compression and valve timing.
I think the money will be better spent on guiness, pies and rolling in last as someone needs to take one for the team.
Just got to put it back together now.

Hi Kev, I am unsure. I have looked at the embossed date stamp which looks like 93, the cylinder head has 8S, the belt adjusters are on the barrels and it has the rounded belt teeth.
perhaps I should try a 44 rear sprocket?
