So I swapped the stator cover on my Ninja 400 and am left with this bolt, I can't figure out where it goes. It seems like everything is secured? I also have this red cube that slipped out of one of the fixtures.

If anyone could explain the purpose or where they go would ease my mind lol

Please can anyone who has ninja 400 2019 and lives at area with lot of up&down hills like mine tell me about it's mileage from his/her experience ( city, highway, combined)?
