excessive play ?
 

Hi

I've have just noticed that when i have my bike up on the center stand and hold the back wheel i can move the rear sprocket and hub back and forth with out the wheel moving, not a lot but a bit, is this normal ? does it make sense what i'm trying to explain ?

The sprocket carrier mounts in rubber bushings. When they wear out, they cause the carrier to be loose.

Time for some new cush drive bushings.
Super easy to replace too. Just take the wheel off and remove the carrier. They probably will just fall out

Cheers pal :)
