Any idea what this is supposed to do? It comes up in the list of parts for a YZ 400.

It looks like a muffler bearing. :)

I think its a vent canister for your carb vent tubes. You put a "T" in the vent tubes and run another line off each side of the carb to the air box and into that canister, which is probably nothing more than a mini air filter. It is supposed to help your bike not bog off big landings and not stall when going through deep water. PC racing makes a similar kit.
