breather problems

hay people,got loads of problems but first off i have got loads of oil coming out of my oil breather on rockercover  it runs to a catch can and that fills up and over flows quite often,just had cylinder head done ported and polished running bike carbs need setting up i think running crap!! any ideas on this??

Well I just thought I'd say I fixed it on own Inishative and for people out there who might have a similar prob there is a plastic splash tray that sits under rocker cover some idot removed it so the oil was coming through breather pipe didn't kno there was ment 2 be 1 but all sorted now so that's gd now just a million more 2 do!!
