Make sure you didn't overfill your oil amount.

Please be more specific

sorry mate its my first time on a forum

Just had a rebuild 5th 4th and selector fork new piston and rings cam chain oil is spot on but oil is coming out the breather and the bike seems breathing heavy out the same pipe

It sounds like you have too much oil in the bike.  They only take 1000 cc or 1 quart.  The other option is that the oil filter is in backwards or not at all, but that is very unlikely.
