Excessive oil in airbox and cylinders?

[duc848]

I had noticed last week before going on a ride there was alot of oil under the manifold on my M8. I wen to take care of it yesterday and ended up pulling the y pipe off as there was oil leaking from the bottom of the gaskets.
I have never seen so much oil in a sled ever. The pistons, cylinders, and y pipe are full of black burned oil. So I decided to look in the airbox. I removed the airbox an there is raw unburned oil all over in front of the throttle bodies. I mean there is a small puddle in there.
I checked the oil pump and it doesn't seem to be sticking.

I guess my point is that I am done with the oil injection. I am going to pre mix. Anyoneelse have all this excessive oil?

Thanks

My wifes 08 M8 has some raw unburned oil in the intake, but the thing runs fine so I dont worry about it.

I had two M sleds a 7 and 8 that when left to sit for an extended period the check valves on the front of the oiler were leaking. Had those replaced and the oil puddles stopped.

I had the oil pump check valve replaced under warranty awhile ago on my 09.

Airbox was full of oil after it sat for a while.

Also like to spit oil out of the y-pipe.

Check valve replaced and no more problems.
