oil quantity strangeness

[Cormanus]

I've never known changing the oil on the CB1100, or any of my inline-4s to be messy.

Heck, the messiest part may have been pouring the used oil into a container for recycling and drying up the catch pan.

@GO: There must be a misunderstanding. Oil change isn't messy at all, very simple job indeed. But draining 200ml of oil through the drain bolt, while keeping 3 or 3.5 L of clean, new oil inside the engine, is - believe me - a messy job. Of course I could have drained it all, collect it, and refill it. But this just seemed ... TOO much for such a rainy day

j3gq, I always change the filter as well as the oil and the bike takes the recommended 3.9 litres.

I didn't want to do the filter as the user manual (EX, 2017) requires the filter change every 2nd year only, but the oil every year.

Sure, my manual says the same thing. I was, however, trying to make the point that, in my experience the quantity of oil specified is correct.
