Honestly can't say. I opted to leave my Pair Valve and Air Box intact, so never really bothered investigating the removal process. I'm not a reliable source for you on this. I'm literally learning about it along side you.
I did confirm that you need to perform the Air Box Mod though. I'm still digging around for information, but maybe this can help you....
The TL1000R is the only bike that makes me nervous, because in my dreams it's the only bike I die on
