yep.... run low on oil. somebody cleaned the oil filter because it would normally be full of aluminum after this type of failure. I have rescued a couple of these. as mentioned above, pull the screen. flush everything out with kerosene & it should be OK. oil comes to the top end through a metal line at the back of the intake cam. pull the line & flush it. I anneal the copper washers & reuse them. now would be a good time to upgrade to a 685/688 piston too. the early (Gen I) piston rings are no longer available, so if you want new rings you have to buy a piston anyway. might as well get one that don't burn oil
