So I tried to get a TC airbox cover for my TXC through the various dealers and they couldn't get me one. After 3 months waiting I resorted to the following:
Ace hardware sells a bag of 6 3" aluminum vents for 15 bucks (enough for 2 bikes):

Short story is drill holes and secure in place with RTV silicone, making sure you leave enough space above for filter cage and sponge filter. I used a metric 74mm hole saw and the vents fit so snug, they probably don't even need the silicone to secure:


The thing I like about this design (since I still have my Zipty crankcase breather routed to the airbox) is oil doesn't drip out of the aluminum vents because of the internal 'lip'.
