Your assesment of the oil problem is pretty much spot on, something a lot of fellows haven't stumbled on to yet, sounds like. Back in the late 60's, Cummins Diesel had just ventured into the V series of engines, and were experiencing some oil related problems, so we bought a large tilt table, about 8' square, and about 6' off the floor, and it also swiveled, which allowed me to not only tilt the engine, but tip it at all angles. I took oil pans, valve covers, gear covers, anything I could put a window in, and ran engines on this stand for over a year, and you can't imagine what goes on inside an engine. At some speeds, everything was as it should be, but increase it even a little bit, and the rear gear train would pick up oil, and suddenly the overhead was full of oil, and the oil pan was dangerously low, then it would stabilize, then it would just be a mist, all the oil was in suspension. To make it short, I finally got vents located where this was manageable, and the problem was solved. In these modern bike engines, especially with a wet sump system, probably close to 80-90% of your oil is in suspension, very little left for the pickup to get to, hence blown engines. Anything you can do to help this oil vent, and get the air out of the crankcase, will let your engine live to fight another day, more baffles around the pickup, better locations for vents, bigger vent hoses, more oil capacity, sometimes it doesn't take much, just in the right place, the cam chain carries up a lot of oil, and also adds air to it, making it hard to get back in the sump. Look at the inside sometime, and imagine where you could make it better for racing purposes, it just might make your engines last longer. Bob!
