Hi all, heads were removed from the engine and the guys at Ducati found signs that a metal ring/washer something was inside the horizontal cylinder and was beaten between the cylinder head and the piston. The problem is nothing was found inside so they assumed that whatever it was it was thrown outside on the exhaust...
Piston rings are all fine, so what entered the cylinder definatelly came from the admission...
They checked underneath the tank/fuel pump/throttle bodies and everything is in place..
Sorry, If I'm picked up any of this wrongly : this problem only started or was noticed after the bike had been in for work to be done, viz on the throttle bodies/linkage ? After which you found some evidence of lack of attention to detail - missing seal ? Yes/no ? Then a foreign body is found in cylinder, - well, call me old fashioned etc, and whilst one wouldn't want to speak on the specifics of this case, one could make a pretty powerful case for the theory that something plopped in to induction when throttle bodies were exposed (airbox removed), - you are very lucky that this apparently did not cause damage - you might want, out of interest, to get compression checks done (if not already) on each cylinder.
Where did the foreign body come from !! It cant get in past filters in normal operation, and it didn't drop off anything inside airbox.....
Very curious, but I guess kind of re-assuring that they found something.
