If you want a bolt on breather that helps to manage (NOT cure) wet sumping, then this is my advice:
You still need to keep an eye on things, and if the bike has been left long enough for the oil level to drop below the gauze in the tank outlet, then you should still drain the sump by removing the drain screw and kicking it over a few times. But, in normal use inc being parked up for 2-3 weeks, this breather does a perfect job of evacuating sump oil back to the tank.
