CBR 125 problem
 

Hi guys I have a new problem lol. Well basically the other day I replaced the head gasket as the old one had blown and now water has started to leak into the oil. I have checked the pipes are correct and I think they are. And I am losing water way too fast ofr it to be a crack in the case, Has anyone got a coolan system diagram? Or maybe an idea what it could be?

As an example of how fast I am losing water after a 15km trip all water from my back has gone.
