interesting find

I was putting a crank back together today and I was checking the timing shaft to make sure everything was ok. I removed the OPR valve and there was a lump of rubber stuck in behind the OPR. It is about8mm long and an oval shape between 8/10mm across the oval. This motor had obviously failed previously because it had been rebuilt because when I originally pulled it down it had mismatched cases and the rockers were filled solid with whitemetal.The new owner only rode the bike a few ks before the scavenge pump seal blew out so I sugested we look at the rockers and sure enough blocked solid. This rubber doesn't appear to have come from the worm nut so my only thoughts are that this has been maliciously put in through the quill bolt, so if you plan on upsetting somebody, keep an eye on your quill bolt lol
