Oil In my Air box. Is this normal?

[RX-1 Thunder]

I have a 03 RX1. The only mods include a Bender exhaust and a Hauck stage 3 clutch kit. I am getting oil in my air box and am not sure where it is coming from. Is this happening to any of you guys? My dealer told me to cut a 1 inch slit in the big breather hose that comes from the motor into the air box. I guess it was an update for the 03's. The sled runs great. Punished a few F7's this weekend! Any thoughts?

Thanks

It's normal with High RPM running. It's coming from the crank case breather tube.

Thanks. It sounds like it is normal then.

RX1 Thunder- curious, what is a Hauck stage 3 kit? Wts., springs, helix and gear change? Tx Longshot. Also, are you happy with it?

It just comes with a primary spring, secondary spring and helix. No weights and no gear change. I am pretty happy so far. It pulls about 3 sled lengths on a stock RX1. I really need weights though. It is rpming at 10,400 to 10,500. I think the exhaust is causing that.
