Hi @Ed K (since you replied in my introduction thread) and all,
since a few days, by now 2-3 weeks actually, I have a whining noise whenever I let the bike roll with clutch engaged.When I pull the clutch it goes away (edit: it doesn't go away, it's just less "frequent" and with less volume but same pitch, see post 20, also for more hints to its origin). The noise appeared suddenly and one day disappeared after I topped up the engine oil (it was just at the lower mark), but since then it came back two days later. I put in around 500ml of oil in total, which I think is already a lot. Somewhere I read that a dry clutch seal ring ("the big one") can make such noise.
In the audio file it starts standing on an empty stretch of road, then I accelerate and shift in 2nd gear and then let it roll in gear, shift down once and let it roll until it stops. Then I accelerate again, shift into 3rd gear and let it roll again. I think I stopped in 2nd gear, but it doesn't matter. At the end the noise stays while the bike stands still, this was new to me today. Then I rev the engine a bit because usually while standing the noise goes away, and it almost does (listen to the last 3 sec).
Also I went around the bike with my earbut I wasn't able to locate the noise... (see post 20, it's around the airbox) What do you think that is?
