decon Posted March 1, 2012 Report Share Posted March 1, 2012 My buddies bike has been acting funny lately, everytime he rides it the breather tube spits up oil all over his exhaust and motor. It only does it when the bike is warm. At first we thought it was leaking from the gasket so we changed it and put in fresh oil but come to find out it was coming from the breather tube that runs to the engine case. He has a lockout so the tube coming from the clutch case has been eliminated, my question is what could be causing this? Prior to this the bike has been running fine with no problems at all, what would make this happen and how can we fix it? Quote Link to comment Share on other sites More sharing options...
Boston Posted March 1, 2012 Report Share Posted March 1, 2012 maybe plugged or adding to much oil? Quote Link to comment Share on other sites More sharing options...
ticktock Posted March 1, 2012 Report Share Posted March 1, 2012 Leak down test that bitch. If you have oil in the breather tube it's not a good thing. It could be right side crank seal is bad. Adam Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted March 1, 2012 Report Share Posted March 1, 2012 Yeah I'm leaning towards the crank seal. It's putting pressure in the case so its spitting out oil. Quote Link to comment Share on other sites More sharing options...
decon Posted March 7, 2012 Author Report Share Posted March 7, 2012 Thanks for the replies, my buddy decided to drop the bike off at a local shop to get fixed. Hopefully the crank seal is the problem. Quote Link to comment Share on other sites More sharing options...
wfobasheeboy Posted March 7, 2012 Report Share Posted March 7, 2012 Sound like the oil is over full. When I first got my Bike the trans oil was over full not by much & it would push oil out the Breather. If oil level is good then its time for a leak test. Just my 2cents Quote Link to comment Share on other sites More sharing options...

Just my 2cents We thought that was the problem as well but not in this case, it leaks so much that it will actually cause the oil level to drop pretty low. Even when we changed the gasket on the clutch cover and put in new oil we made sure not to over fill it, it still would leak out of the breather tube. So like they said something is putting pressure inside of the case. Quote Link to comment Share on other sites More sharing options...
