I need adviсe for my 900 :-)
How it all began.
At first - I bougth a dual injector nozzle for scorttoiler and began my long long adjusting journey :-)
During it I saw than my new rear sprocket which was installed in winter is not absolutly vertical. It have runout is about 1mm in horizontal plane when wheel rotate.
My first think - incorrect rubber damper installation. I reassemble rear wheel and ... no positive result.
Further I checked all bearings - no noise, no gaps.
Then I changed old sprocket back and see 1mm runout again.
Unfortunately I don't know when problem is started. I think in autumn everything was ok, or not ...
Now I have only one version of failure - sprocket bearing or/and collar, which pressed in bearing.
Maybe collar have a little deformation of contact surface and when we tight all parts by nut the sprocket have some runout.
What you think about it?
How fast can it break my new chain and sprockets :-)?
