No. Mine doesn't but it may be overfilled. When you check it how do you check it. And I don;t mean "with the dipstick" What are the otehr conditions?

I had oil come out of my crankcase breather. There are 3 reasons for it. First is simply too much oil in the bike. Second is extended high rpm full throttle operation. Think racing in the baja 1000. Wide open at 90+mph for extended periods. This will cause some oil to blow out the crankcase breather even in a properly operating engine.

Third is the combustion gas blow by. This happened to my 600. Oil was running out the breather every time I stopped. I had to add oil every ride. Mine was worn out rings. When I took it apart the ring end gap was huge. It must have been .150 if not .200. I put the ring in the bore to measure it, and just started laughing when I saw it. Since I know that you just built your bike, perhaps the rings haven't seated yet and there is still excessive blow by. Keep riding it and see if it gets less. Sometimes rings never seat and the bore has to be honed again for another try at seating. Try a compression check. If it's bad enough to blow oil, the compression should be a bit low.

Proper technique helps with ring seating. I read that a dry assemble (for the rings) helps a lot. It goes against everything that I think is right, but I tried it. I also did the harder break in. I parked at the base of a 200 foot tall hill and did hill climbs for the first 1/2 hour. My bike has never blown oil out the crankcase breather since.

If you are talking about leaking from the head cover, and leaking down, it is fairly common. Sometimes it means that the threads in the head are bad and need a helicoil. If the gasket surfaces get dinged then they don't come together properly. A little sand paper can fix that. I've also had rocker shaft leak. I had to replace the copper washers (gaskets) to stop that. Mine leaks a little from the head cover and I just live with it.

What year is it?

Basically totally drain the oil from the filter, and crankcase. Put in 1 quart, then most of the second quart. Start the bike and let it warm up then let it idle for about 30 seconds and turn it off and check the oil via the dipstick, top off as needed by the full mark on the dipstick. DO NOT OVER FILL!
