Hi, have a 2021 X4 - there is a knocking/clanking noise - imagine hitting a screwdriver shaft against something - there is no pattern to the noise besides being constant - but not in any sort of rhythm. It comes and goes, but mostly there, it does it on acceleration, climbing, cruising on even ground, braking - there is nothing that duplicates it. The sound isn't cyclical, as in something spinning is loose, so tap tap tap every rotation or similar. I took it to Yamaha, they said it was something inside the tranny and that is normal, but it doesn't feel/sound normal - I took it apart (panels etc, not the tranny or anything) to see if I an see anything - nope, all looked solid to me. It will go minutes without a noise and them it starts - anyone have anything similar on these 2021 Wolverines?
