Lemme suggest this, do not even use the stoopid crankcase thingamabob. Just take a piece of hose that will connect to the crankcase vent on the side cover then route it and zip tie it so that it pukes onto your chain. The breather/filters are a PITA and need constant emptying and cleaning. And if they get full, they blow oil all over your motor in the hard to clean places to boot.
So the EPA may stop you and give ya a sermon, but the heck with them, I'm a rebel.
