    I just finished changing my oil on my 310. I started it will the fill plug out and noticed alot of pressuer blowing out of hole. I removed the valve cover breather hose and it did not reduce the pressure comming from the oil fill hole. I rechecked my valve adjustment and they were fine. My question is it this normal or do I have ring or valve issue? Thanks.

    For one thing, your clutch basket is spinning very close to that opening, so you probably are getting a little "wind storm" off of that.:D I'm surprised that oil didn't come splattering out of the filler too.

    Lots of reciprocating bits inside the engine down low near the level hole. About the only way to stop that is to stop the bike ;)

    Oil was spitting out. I started bike with the plug in and the turn it out and when it got to the last thread it popped out from the pressure. The bike runs fine so maybe it's normal from the spinning clutch. Thanks
