No one is going to be able to help you if they can't understand what you are trying to ask. Please try to use complete sentences and we'll see if we can make heads or tails of the situation.

sorry man, it looks like a blown rear manifold, isn't that what they call the rubber boot on the carb.? blew oil back into the uni, foam pod style filter and the filter is dripping. rear cylinder was knocking a little before not a cam chain thing I don't believe

Hmmm... There shouldn't be oil in carbs. Unless you have blown out piston rings. The carb boot would be massive air leaks and really bad running condition. Could be a blown head gasket but usually that would cause overheating first. Someone with better diagnostic skills will chime in.

It's called a rubber boot! One of those goes bad, highly unlikely. Definitly would not have oil come back good nor bad ever! Oil coming back, sounds like the rings are fried, try a compression check!

shooting oil directly on (outside of) filter & carb??
seems more likely than oil coming back thru the carb if it was still running at all.
compression check never hurt anybody though, especially with the miles you got on that beast.

Guess if your carb boot was leaking, oil could get all over the outside of the carb, if that's what you mean. pull one of the rear plugs - if it's filthy with oil, you know where to start. 52K could be a lot if you don't know how well POs took care of it....it's a lot of miles if the oil was changed only 2 or 3 times, or the coolant wasn't checked and overheated a few times.
