Well, what's kept me from one way valving the crankcase is an unknown in the design. Take any single cyl or variation of a v twin and just about all of them have a one way valve in them to bring the case to static or slight vac. The unknown here is why wasn't it done with the Revolution. Is there some underlying design intent regarding long term lubrication in some part of the engine or trans that a one way case venting could screw up some? I've not come up with the answer yet.

A quick search located a few threads where other forum members tried check valves to improve on the OEM crankcase vent system; e.g. this one.
In this thread an aftermarket oil catch can, check valves, and the MotoHooligan airbox are all discussed. (Ron, you posted in this thread).

Thanks for reminding me about repeating myself.
I did however come up with a one way breather valve head that replaced the existing cansister cap which a hose could exit out the bottom of the breather box and either to a catch can or just under the bike. Got as far as a quick sketch but no actual prints. I'm retired now so no machine shop available and not a lot of interest to pursue it. Me personally I get very little oil in the box but I do see some carbon on the intake valves from oil misting.
