Want to added my experience with the gear oil change to this thread.
Did mine after 13h 23min, was having to much fun riding the bike and kept missing the opportunity to do the gear oil change.
But was able to remove the drain bolt without stripping it. It’s definitely a tight fit and if the torx bit doesn’t sit in properly it will strip. I inserted the torx bit by hand to make sure it was straight and then used the extension to lightly tap it in further with a small hammer.
For sure that bolt is way over tighten from the factory as it took a lot of force to break the bolt loose.
Had the same results like others here with a milky color oil which seems that is the result of water getting into the gears. I have done around 6 washes with a hose and a shower nozzle. Going to use a clamp to seal the breather hose when washing to see if that helps with not getting a milky oil since I don’t ride in wet conditions.
Overall taking it slow to remove the drain bolt and then tightening to 12 nm felt plenty tight to me.
