the parts found looks now that you mention it like the cage around each ball in a ball bearing unit.
all the bits were found in the rear screen everything else is clean I filtered the oil and nothing was found in the pan nor in the oil I have not removed the oil filter but my guess is there would not be anything there . I kind of limped back home after about 15 miles of riding this morning taking it very easy so nothing grenaded , my regular shop tell me they cannot look at the bike till the snow fall!! so plan number two go to an independant and cross my fingers
I am not confident enough to start pulling part of that engine anyway just as I was planning a trip to jasper
