250-500cc 2010 wr300 oil leak out of breather hose

so my bike when layed over on it side 40 hours into a full bottom end rebuild starts too leak oil out the breather hose anyone have any idea why it would do that?

That's pretty normal if the bike is layed all the way down on its right side, what I did was re-route that breather tube up , next to the shock hydrogen body and into the upper part of the air box, where the rubber part is, than back down and zip tied it to the bolt for the right side cover inside the air box.

I can get you a photo is you want...

That way no oil is spilled, and more important, no water get in during some 'snorkeling'

sweet thanks thought so haven't touched the bike for a couple months just wanted some input

everything looking dialed
changed the oil headed towards a hangover scramble in the am!
happy new years
