I'm not telling you to do this......but.. I removed all that stuff over 3 years ago, before I ever started my scooter.
The necessary hoses are, the crankcase vent(from valve cover), the gas tank vent line, and the transmission vent hose(the one at the rear of the air box). A small fuel filter placed on these vent hoses will keep the dirt out. I made a catch can for the crankcase vent, just to monitor what is being expelled, but it isn't a must do.
All the rest can go, along with the attached canisters. A block off plate can be purchased, to cover the opening left when removing large hose from exhaust header area.
