There is no way of knowing what is inside the crankcases, or has contaminated the oil passages and bearings.
If it were my bike I would not spend a penny on that engine until it was completely disassembled and inspected.
I'll second that. With all that debris sitting in the bottom of the cam chest, plus a locked up oil pump, I think the whole thing needs to get pulled apart. Including splitting the wheels and going through the con-rod bearings.
Those marks in the oil pump that Daven9113 posted seriously look like a cam needle bearing mark in the housing AND...
Dan89FLSTC is absolutely correct....
How should a cam needle come into the oil pump?
I never heard that and also don't see how that should happen.
Of course the mark looks strange but I can't believe its from a needle.
To me, that mark looks sort of like the pump gear got wonky and banged it when something got stuck in the drive gear in the timing chest. The 2 marks look spaced like 2 cogs of the pump gear. The bore that the shaft runs through may be toast now. Probably best to just replace the pump.
