Where do you have your crank case vent going to? Mine had a lot of oil in impeller housing and actually dripped on the floor after siting for a bit. If you do it they way they recommend the vent hose is actually down hill to the impeller housing and must draw oil out of the crank case especially if you are drawing snow dust to the filter causing more draw on the vent. I took mine out of the impeller housing and went up over the delta box and put a 90 elbow in and routed it back and up. Call G-Force and they will probably send you the small K&N filter that the original kit's came with and install it in the vent hose. I don't have a lot of mile's on mine since the change but i think it will solve the problem. I think i will still have some oil residue but should be tolerable. I had no problem before i put the up date in and changed the vent hose. Keep in mind the stock air box always had oil in it even with the vent going up in to the air box and that is normal.

I did notice oil consumption after the up date. I would bet any thing that is where your oil is going. Mine seems to be back to normal after moving the vent tube out of the impeller housing and up. I don't think the oil was being burned but was ending up dripping off the bottom of the sled. You should not be over 10,800 unless you have the ignition module with timing and rev limiter change. Good luck!
