Also after this experiment I decide the drop the sump plug and see whats in the sump. I didn't take a picture but there was 14oz of oil in the sump.
So could it be my oil pump is just not effective enough at cruising speed to keep the sump scavenged? If so then is there some pictures of what I have to do to make this thing a done deal and get it running right?
14 oz of oil in the sump immediately after shutdown is quite a bit. I am thinking there may be a problem with the scavenge side of the oil pump. If the bike sat for a few hours before you checked- then that may be normal.
I see two possibilities. Either excess crankcase pressure before the breather was fitted has dislodged the crankshaft oil seal or the oil pump has damage and is not scavenging the cases well enough.
If you look into the top of the oil tank after the engine has been warmed up you should see oil return squirting from the holes in the tube visible under the cap. It should be squirts of oil mixed with pockets of air .. If there is only a slow stream of oil but no air pockets with the engine at 12 to 15 hundred RPM then the scavenge side of the oil pump likely has had some foreign material run through it and has damaged gears. Removing the oil pump and inspecting it is easy. The hardest part is re-setting the timing.
Set the engine at the timing mark in the primary chaincase and then mark the position of the timing rotor in relation to the timing cover before you pull the rotor to help get it back where it was when you re-assemble it. Feel free to call me if you want to discuss the problem. Jim 719-821-5708
Yeah I am thinking now on the lines of the oil pump being buggered up or something. I have the primary cover off though so it doesnt take me longer than 15 min to get to the crank oil seal as well. When it cools down today I may just get at both of them to see if the oil seal is messed up, then I will take the timing cover off and get to the oil pump.
I have electronic ignition so its pretty easy to set that back up. I also can do the mechanical timing as I have had tons of practice with that too. I usually get something right by doing it 15 times.
When I get the oil pump out I will have to learn as I go though as I have not seen a good walkthrough anywhere on servicing one. I just see lots of talk about the grinding, lapping and such.

No actual detailed articles with pictures for me though. I guess not everything is idiot proof.
Now for the Sump breather, I am thinking I need to search for root cause and see how it performs without the breather. I only want to add it if it enhances the performance or function. Of course I am open to understanding how the experts weigh in on the situation.
So in this order I will
#1 remove primary chain and pull/inspect the crank oil seal.
If seal is messed up ripped etc I will reinstall new one and button it up to give it another whirl.
If seal is good I will go on to #2....
#2 Pull timing cover and take apart oil pump. Take a bunch of pictures and figure that deal out.
