2015 XMR 100 hr service issues

So today I tackled the 25, 50, and 100 maintainance items. Got a couple of wtf where they thinking on this bike. First of all look at the photos below. Owners manual says 75/140 oil for the rear dif yet it is stamped 75/90!? Filled it will 75/140 but wonder why they have that stamp…..

How the F do you replace the front cylinder spark plug? It appears the cvt exhaust "redirect" is in the way and is impossible to remove. Stock cvt snorkels are also in the way and sealed so I dont want to unseal them…anyone replace theirs yet?

Just FYI. The service manual says to remove the 2 rear bolts from the airbox to remove the throttle body…. Yeah well that plastic will break when you try to pry the throttle body out. Also you have to loosen the front bolts of the airbox (nut is hidden and difficult to get to) in order to reinstall it. Won’t be doing that again as it was spotless at 93 hours.

Everything else was ok to figure out/ service. Didn’t do the pressure tests as everything is spotless and running perfect.
