Crankcase evacuation valve

[Krandall]

I gotcha. It sorta makes sense.. It makes the most sense on the up stroke creating the vaccum making a better seal. But what's wrong with just letting it breathe like it is set up stock?  I mean sure you don't get the vaccum, but it'd be letting out the pressure just the same correct?

Someone eles said expained it as if you were to put a brick and a feather in a jar and suck all the air out of it. They would both fall at the same rate. Its all about resistance.

As it is set up stock, it sucks and blows with every stroke get your mind out of the gutter, that is the best way to describe it.

I was just thinking about that statement was all.. But in a nutshell the whole thing makes sense to me now. nice work kenny

Have you tried yours yet?

I  gave mine to my buddy with a Z400 to try & he hasn't yet installed

So... I'm on my second clutch cover gasket.  Any chance this baby will keep "pressure" down on that side of the motor???

word for word in what it does it's just not routed back into the air intake for emission reasons....

I have both types of valves and love them both.
They definitely have a great product at a great price.

Love that quad Rich 

BTW, wasn't it just in July Dirt wheels?  :grin_nod:

[richw3533]

It was actually.  My R1 bike will be in there soon also.

Thank you very much for noticing.

It does perform the same function, but the internal design is far superior. The guy that builds these for me has a patent on the design. They are far more sensitive and durable. They also withstand nitromethane and methanol. A PCV valve off the shelf doesn't seal like these do, and they fail every time. So in the strict sense of the term it is, but the performance is nowhere close. I've already had guys trying to save a few bucks, and getting covered with oil when a PCV valve fails

hmmm same idea kinda but not so much

So, is anyone installing a filter on this thing to keep dirt from settling in there? I have to install mine and I bought a stainless mesh breather to put on the end of it.

Any Thoughts?

Yes, there should be some sort of precaution taken to keep dirt out.
