| 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? |
