Whats this and whats it do? I noticed not all scramblers have this box. Even pictures of the same model don't all have this thing. What does it do? I looked through all of the OEM diagrams and can't find it anywhere.

It's a carbon canister that catches petrol fumes from the fuel tank so that it's not released into the atmosphere thus making your bike an environmentally friendly machine.

You see it on some and not on others because some governments require it and some don't. Also, some owners simply remove it as it makes no difference to the performance of the engine.

Edit: nvm, used search and found the thread to remove it. Thanks Phil!
