Oil overflow.

[Trick2stroke]

After a while of riding my case vent hose seems to act like a syphon and steadily dumps out my oil untill it's low enough that my shifter get's stuck and won't shift up more then 1 gear and won't shift down at all.

 

Seems like I've seen where other people have had this problem of their oil being syphoned out. I did a search but didn't find much of anything. I need to find out why it's doing this and what I need to do to prevent it.

 

Anyone have some insight to this problem?

have you solved the problem yet because my o3 special edition is doing the same thing? i was told it could be the oil seals on the crank so i checked and they dont appear to be bad. i was also told that the yamabond between the cases has blown out and slowly causes crankcase pressure to build up and start pumping out the vent tube i havent checked this yet.

How did you check the crank seals, visually? You need to do a leakdown test to check those babies, as well as the head, cyl's, cases.
