It will cause the oil to puddle between the top cover and gaskets and the oil will come out the tube.
Usually when you run above idle. ...........lm

Have you taken the top cover off the engine?. .........lm

The oil level is correct (it was down), took the side cover off cleaned everything up and rode it 1/2 mile no leak, ran it two miles at 55 and it spewed again. is there a vent that could be plugged and causing it to overheat?
I'm confused!
If I'm looking at it correctly, that's where I was thinking the oil was coming from, that dumps into the side cover through a rubber line. Am I looking at that correctly?

Thanks, I will check that and adjust the tappets and see if that clears it up

Not good, poor compression even after adjusting the tappets, checked the top cover, that was correct. Thinking its a ring or valve...

Do I have the same problem? Lost power and stalled after running about 20 minutes at pretty high RPM's. I noticed oil leaking from the right side cover so i trailered it home. When I removed the right side cover this is what I found. The bike has been in my family since new and has about 27k miles on it without any motor work ever being done. Hopefully I can get it up and running again.

Thanks,

Brian

I thought i must have blown an oil seal but when i read this post i started wondering if it came out of the vent hose. It was quite a bit of oil and seems to be way to much to have come out of the vent house. The oil in the pic doesn't show all the oil that leaked out onto the ground.
