Hello Tremonte, thank you for your videos and detailed reviews, it's because of you I got a z650 and loving it. Just a quick question if you don't mind, when I turn off the bike and whirring sound is happening, I noticed the other day that the accelerator gets pulled and then it returns to normal, is it supposed to do that ? I tried googling it but to no avail. Thank you for your time, have a great day and ride safe !
