	Alternative supplier to Aprilia, both versions do the same thing but are slightly different designs.

	I think they are still colour coded though. Black one side and white the other side. Black side faces wherever the vacuum is coming from. i.e. the intake throttle bodies. Basically the way I see it is the throttle bodies can create a vacuum to the pipes that are connected to it by sucking air in, but cannot put pressure back down the pipes because of the valve. The flapper valve works on vacuum and so does the clutch, so as long as the valve allows air to go to the throttle bodies only, then all is good. There are lots of different types and you can also upgrade them to better ones instead of using the OEM ones that can fail and cause running problems. I'm not a mechanic just something I picked up from working recently on my bike so don't quote me on any of that, but I believe I am right.
