Trying to learn something here...
So the suction side of the oil pump is able to pull oil and air without affecting the discharge flow or pressure. Seems that the pump would "gas off" or for lack of a better explanation loose suction and cavitate.. Further; I would think that an air mix would create a false high oil level.
Guess I just don't see what's going on internally, I'm not a mechanic

I rode mine most of the day and checked the crankcase oil (many times) and just didn't see this foaming business as I did when the bike was stock (CC temps 260-270). Today, no foaming, didn't matter if the engine was running or not... Ambient temp was 65 and the crankcase temp didn't get above 230.
I'm confused bout this issue. Geezzz, I've got a lot of respect for you guys. Are you sure this oil foam is normal ?
