If it's not leaking out, it must be blowing out your exhaust.
Stick a piece of white paper or a white towel behind the pipe with the motor running and see if oil is blowing out.
Maybe bad rings or valves not seating or both?

My guess is that this guy Image took it. Thats the same look my 3yr old has when he's done something he shouldn't. I'd start by putting him in time out until he's ready to talk.

Since you eliminated your stock air filter box, where/how are you venting the crankcase? I assume that that K&N looking filter in the lower left of the picture is attached to the valve cover and is part of your vent system. Are there any others?

The oil can disappear in one of four ways:

1) Leaking out the crankcase.

2) Getting blown out via any crankcase vent system(s).

3) Getting burned in the combustion chamber due to oil getting pass either the piston rings or valve seals.

4) Someone in your neighborhood/family is playing a mean trick on you by draining your oil while you're asleep.

Now if your crankcase vent system is not allowing enough pressure to escape, then you can have excess pressure build-up in the crankcase which can potentially force oil pass the valve seals or piston rings. If this is the case, then it should show up on your spark plug (very black or oilly looking) or a very carbonized exhaust and/or wet oilly looking exhaust tip.

Breather filter on the valve cover. There are no other other vents. #4 thats probably it. Image

I'm gonna try and put the valve cover vent into the UNI filter neck with a hose and a coupler.

Are you talking about crankcase oil or oil on the Uni filter foam?

I'm Sorry.

engine oil is low during an oil change. I use 10w40 weight oil. My guage cluster reads kilometers and it says change oil every 1000 kilometers, or when the red number apears on the odometer.
