Hiya, I had my mechanic fit a rear tyre whilst doing an MOT on my 08 xt660z today and he said he had to put a new sprocket carrier bearing in because the cush drive was knackered. He said I need cush drive and carrier asap and a new chain and sprockets to follow cos they'd worn unevenly due to the worn sprocket carrier and cush drives.
I'll get the cush drives no prob but is there a way of checking the carrier for wear once I've installed new drives or should I just change both?
Also, does the z share its sprocket carrier with the x and r do you know?

Cheers

Jay
