Pigtails or Hayden oil fix

Looks an interesting item, but guess it is just a ribber flap onto a seat. Mine is bottom breathing and I just run the pipe to a small filter under the bike.... Will this improve anything? it may help create a bit of negative pressure maybe?

My Evo, Shovel, and Indian are all case breathers, and I have one of these vent valves in the vent line on all of them. This essentially copies the same idea as head breathers, in fact the valve (which is replaceable) looks just like the valve in a head breather. It's just a one way rubber valve.

What's the difference between this and a $5 inline PCV valve, I get the concept and don't disagree with the idea.

What type of valve?.. like a one way valve with a ball and spring, or a rubber disc type?.. they may be available where as these arn't

The automotive PCV valve is not a positive seal.  It will bypass in the closed position.  It was a topic of discussion here a couple of years or so previous.

Okay, pigtails made.. just wondering how long the head is.. don't want it too long as it will take on heat and creat a hot spot... any idea what thread length you've used as I could always make these a tad shorter

A little late, but here ya go.
