It's long since I rode my '9 from last time (2007 model with 55K miles), but now I'm planning to get back to it pretty soon, after some important fix .
I brought her to my mechanic in NOV-2019 due to a weird "zzzzzz" noise coming apparently from next to my left feet when using the bike aggressively on twisty mountain roads ... next a couple of weeks later I crashed with my Kawasaki Versys 1000, had the left hand's bones misaligned and fractured my left big toe .
Now I'm fine again and could ride, unfortunately the lockdown due to the coronavirus is still preventing me from doing it.
The mechanic is working on my '9 in these days to understand what could be the reason of that weird noise, which seemed as caused by two metallic surfaces rubbing on each other.
What he found explains well the problem, as you can see in the pics of the clutch sleeve hub and the drive plate No. 2. What is even more weird to me is that the previous mechanic changed the plates only 14K miles ago (I had plates slipping upon revving above 4000 rpm in all gears), so I really do not understand now what he really changed. All the plates or only a few??
Perhaps he only changed some of the plates and not the drive plate No. 2? I do not remember now.
For information I've attached a pic of also the other plates and the primary driven gear assembly:
Not only the drive plate No. 2 is fried, also the other plates appear quite worn (we're going to measure the thickness).
The gear assembly was quite dirt inside (in the pic is after it was cleaned).
What surprised the mechanic is that the gear assembly appears very little worn (where the driven plates' claws seat in), considered the high bike mileage.
I would like also to change the sleeve hub, because the springs are very loose and rattle a lot. It should cost around 300 Euro, but at least I will get the hub with the new design and reduce the rattle from the stock hub
Have you ever seen such a fried plate?
