check the oil level 1st, overfull conditions will blow oil thru the breather into the box.

Next, why is it overfull? don't know how to check? gas in crankcase?

the crankcase only take 2 qts

I just changed the oil B4 the ride of 40 miles and only put in 2 quarts pet the specs. Oil level on the sight glass was a little over half and now does not register on the glass at all. seems like its pumping it out through the carb and exhaust? Is there a problem with piston and rings on these bikes? Or am I looking at other isssues? I'm a little puzzled. Thanks for you info in advance.

Sure you got the oil drain plug?... Open your airbox and see how much liquid is in there...

I'm sure I got the right plug 2 qts. came out when I drained it. The air box had so much oil come out of it I had to put a drain pan under it. When a helper tipped the bike about a quart total I bet. I drained the oil again and only had a quart left in it after only 40 mile trip. I may be a noob to this machine, but have owned and maintained bikes for 20 plus years. I'm confused by this one though.

Is there a plug for this?
not thru the carb... thru the breather.

The breather on the rocker cover? It appears to be a hose that goes to the middle of the frame of the bike. Maybe I'm missing something?

I didn't drop the bike and am unsure

Usually, the only thing that causes this is overfilling the oil. Possibly, they left the scrubbie out of the head cover when they did some maintenance.

The hose is clean with no trace of oil. I then removed the carb. to find oil in the intake boot from air box to carb. I then dis-assembled the carb ad it's full of oil also. It seems as if I hade bad rings.

I would disconnect the breather hose from the head, then install a temporary hose to the breather and just run it down to the bottom of the frame. Then go for a ride and see if the oil and/or combustion mix comes out the pipe. If there is a lot of blow by - then it could be rings and/or the missing scrubby. If there is little or no blow by and no oil comes out the breather pipe - then maybe the valve seals are letting oil into the intake tract.

Teggy, we are talking to you about overfilling the oil, and you are talking back saying you don't have that problem.

But it occurs to me you have never told us exactly how you do judge your fill level with the bike being held straight upright & vertical.

How do you manage to see inside the little oil window while you are holding your bike straight up & tilt-free perfectly upright?

Sounds easy, but sounds easy isn't always easy to do.

============

I like Dave's idea about re-routing your top of head big round rubber huff tube temporarily, except I'd put it going right on up to the handle bars so you can see what it is doing going on down the road.

I'd tape off the mating nipple on the airbox shutting it off completely and I'd clean all the oil out that is in the air box now, as well as the half carburetor of oil you say you already have gotten. Start off clean on this test pass.

Wear old clothes and carry a rag to stuff over it if it gets nasty -- the huff tube is called that for a reason. It huffs (puffs and then inhales) one full displacement worth for each RPM done.

Then take a spin with your oil level set correctly with the window and vertical upright bike and the readily visible huff tube, then report what you see after doing that test.

Required test

Feller's... there's a little tube that drops down from the airbox under the bike... it's just in front of the swingarm.. should have a little cap on the end... every oil change,.. you should pull that cap and let the blowby drain... it ain't usually much, but it adds up...

If'n we had us a chain,.. we could use it as a drip oiler...
Highly EPA illegal of course...

Is letting the blowby drain through that tube all that needs to happen in order to drain the airbox? That, I do, but I've never done anything else to drain it.
