Great write up Kim! But I'm wondering if I'm wrong here.

I thought the kleen air system was designed to vent valve-train pressures and vaporized oil to the airbox and thus get burned through the engine, instead of venting to the atmosphere. I thought the extra oil in the air/fuel mixture is what caused the popping in the exhaust?


I didn't realize it injected air into the exhaust system? I thought the valve train was sealed from the combustion chamber? Isn't that what the valve seats are designed to do? And I haven't seen a port leading to the "chimney" on the valve cover from the exhaust ports. What am I getting wrong here?

I removed mine a while ago, simply because it makes maintenance easier. I then put one of those little K&N breather filters on there, and I think it makes it sound awesome. Valve train noise is a little louder, and it makes the thing sound like a machine.
