not the Lunchbox... I know what that is.
What filter is that on the breather line? Is it required?
It's a vent filter like a PCV valve on your car.
PCV vent filter, helps keep trash from going back into the engine through the PCV hose. Wouldn't run without something like that, as there can and should be vacuum every now and then through the hose (at least, there will be on an auto engine).
That's a K&N breather filter. Mine has the same thing. Yes, it's required.
No it is not required. There is a filter (kind of looks like steel wool) in the top of the valve cover that the hose connects to. It does not hurt to have one though.
If you want to get one, the part # is on the wiki at the bottom of the air filter page. Paulin8r used the K&N 62-1320.

That little mesh screen is the perfect place for a small nest of mud daubers. They like small, warm, confined spaces with long, narrow passageways.
Most aircraft engines have open breathers with the mesh vent. Mud daubers love 'em! The only solution is to install a rubber plug and another "remove before flight" streamer.
So true, it's not really required for operation. It's more of an insect barrier.

Right-o I bet 9/10th of Gs rider ride everyday without one.
YOu don't "have" to have one, but I would highly recommend one to keep small dirt particles out. The steel wool like filter that is in the top is supposed to trap and hold oil and then removes particles that way. But even on a stock bike that line is then routed to the airbox

The hose is routed to the airbox to allow any escaping oil to be burned, an emission thing.
I am currently using an inline fuel filter for my crank case breather

Is working well.

Would it be better to use a longer hose and route it somehow so that it doesn't rest on top of the lunchbox? Just wondering...
What would you suppose you would gain, if you did route it further away from the open air filter?
Not necessary, nor desired, in my book. I'm using an old K&N Pre-filter zip-tied around my hose, chopped short. Might as well have it out of the way while working on the carbs.
