Engine Block Offs/ Kleen Air Mod Questions
 

First off, Ive read two different versions of the mod.

There's the mod to where you replace the pair valve with a T connector. Many said this works just fine.

Then there's the mod where you use the included pair valve, rig it up similar to the T using hose 3 in hose 4's place, and unplug the valve.

-Can anyone shed some light why one would be better than the other?
-Is this mod really worth it? I have the bike already taken apart for a CCTL change.

-Also, what do the engine smog blocks do and are they really necessary?
-Where do they go?

I realize there is multiple questions here. Answer best you can.

If you use a tee, you don't have to mess around with taking the internals out of the valve.

If you use the valve you don't have to worry about any blockoffs, because you can use the same plumbing. (I think, Can anybody back me up on this??)

I used a tee, it was easy enough.
