whining noice at 2000-2500 revs

[Virhiryu]

Hi, sadly me 2011 tenere start making dissturbing noice what starts at 2000 revs and peaks at 2500 and then going down again at 3000k and then cant hear nothink due to engine and exaust noice. Starting getting worry about it what can be in issue, its happens all time, riding standing gear no gear clutch no clutch. I had changed a clutch basket for next gen and it dont sound like clutch basket issu as it coming more from a top of the engine, i have a manual tensioner in it so i think it might be a cam chain or slide or a bearing somewere, but tension was set up correctly and check it on slight loose with cam chain knock noice will still doing whining noice on same revs. any ideas or recomendation before i start taking top end apart?

I don't hear anything unusual, sounds a lot like mine normally does. A whine could be a failing stator.
How many miles on the bike? Is your battery voltage while riding staying around 14v?

phone dont pick it up to much but can be heard on the background slippy whining noise... its more on the top part of the engine and didnt had any issues with voltage.

You can play doctor with a plug in one ear and a hose in the other, and so you can centralize the noise
