OK What is a EMISSIONS BLOCKOFF KIT ???

[T-Bone]

Looking at buying a CRF250X and I was told to buy a emissions block off kit ... What exactly is it ?? How will I loose 2lbs by putting it on ??

The block-off kit eliminates the smog pump. It is a little plate with a couple of bolts and an o-ring. Seals the hole where the smog pump connects.

I read on a couple sites that some riding areas in California are inspecting bikes for smog removal kits.
