Some oil mist out the breather is common because the oil is aerosolized by the crankshaft, ans comes out the breather with the air.
If this is too much, the rings might not have sealed well, or you just might be getting more oil thru with the roller bearing.
Anyway, you can always put the catch can on to catch the oil if you want to.

...and don't over fill the oil tank. No more than half way up the dip stick with the cap resting on top of the hole is plenty of oil. Check it about 15-20 minutes AFTER your ride.

Thanks for the tips, Gents.
I didn't mean that there is a big oil leak or it is spewing oil or anything like that, just that there always a couple drops of oil on the ground under the duckbill and that the rear mudguard licence plate area is a bit dirty from dust sticking to the oily mist.

My oil is half way up the dipstick and there is no smoke or wet sparkplug when riding, so I don't believe I have anything getting into the combustion chamber.

A good improvement overall and a worthwhile modification.

The whole rear half of my bike ends up getting sprayed.  She's messy but she never rusts either.   ;)
