Default crankcase breather??

Okay so i have my 01 CBR F4i and the right case cover leaked so i fixedd that with that RTV gasket maker because thats what the honda dealership in town said to use. So i fixed that and no leaks. also did an oil change when i did it. rode it for 3 days with no leak at all and one day i was out doing wheelies and i noticed when i got home it it dripped and when i came out once it cooled down there was only about a 3" circle that was wet under it. so i took it apart looking for the leak and i still couldnt find it. so rode it again and was being good on it and it didnt leak again. now yesterday i went to grad parties and drove nice there. didnt leak at all. then on the way home i raced a buddy of mine that took off in his car to town and thought he'd beat me in his car if he left 5 minutes before me. well got home and it leaked the exact same amount. Is there some sort of breather that oil comes out of or something? its like if im kinda hard on it or run above 10 grand in rpm before shifting it does that.
any sugestions??

you probably just have a crack in it still and when you push the bikes rpms im pretty sure that oil pressure goes up and it just so happens that ur crack is small enough not to leak when ur not going over 10k rpms

could be wrong...
