    May be rings. I would check the valves first

    when You get it started and it gets warmed up. Does it start easier?

    Mine did that. It was the valves. Get it apart andf check them. My exhaust valves were staying open.

    Mine is being a bitch to start now too, and I know the valves haven't been touched in over a year...if ever. So that should fix mine...

    most likely the valves, but monster jumper you may have burnt a ring. Oil in the airbox means your building crankcase pressure which is usually caused by blowby past the piston rings. I just so happen to have a brand new cp piston and top end kit for an ltr450 sitting in my garage if your interested lol Ill even install it ANDD adjust your valves!
