Well, I think I finally got it figured out. Took it to my mechanic today and he did a compression test. Supposed to be about 150 pounds and only have 60 pounds. My mechanic is really surprised because it runs so good, starts right up and no exhaust smoke. He said anything under 80 pounds will make them usually not start or run. He suggested to try the siphon break and see what happens. I got it today and installed it. In about 10 seconds it fills the siphon break cannister and pumps oil out of the filter on the end of the vent hose. There is too much blow by which is causing a large amount of crankcase pressure which is pumping oil out. He is going to change rings and maybe piston, if necessary. Quoted about $515 parts and labor, sounds pretty reasonable to me. He only works on atv's, motorcycles and quads and is pretty well thought of around here.
