Crankcase ventilation: suggestions now that my air box is gone

[MotoPsycho]

That one looks a lot like a Nichols the way it is made. It'll work just fine IMO. I neglected to mention 4 1/2 track days with just the hose. The 1/2 was due to a low side on the left side. No spillage or anything.

So all the crankcase breather filters have a leaf valve?  Besides K&N what other options are there for those breather filters?  I'm a bit worried about the oil leaking but I don't think I have any other option if I relocate the volt regulator the way its relocated in the TPO kit.

The filter is just that, a filter.  The reed (leaf) valves are in the breather valve that screws into the rear of the engine:

Pardon the slight thread jack but with stock airbox setup can a long tube connect the breather to the back of the airbox & ditch the other box/tubing, thats under the seat?

That box under the seat also works as a vapor separator.

From what I remember, vapor in suspension has a tendency to stay in suspension given temperature is high enough. That little box slows down velocity enough that what liquid is there if any will collect in the box and vapor will continue as the air box puts vacuum on it. What I don't know is if any liquid can run back through the valve to the engine.
