keep an eye on kush drive rear wheel !!

[mr-fabricator]

Destroyed mine in 4 track days .

I have shimmed them out to take up the slop and play in the sprocket housing and seems fine now ,

I have never ever noticed kush rubbers going in any of my other bikes . Was shocked for this to happen with just 40hp . And it eventually threw my chain and could have been very nasty at 180kmh . Luckily is was just going into a tight but slow corner ..

Just a heads up and keep checking for play in your hub

That sounds very strange, I've done 3500 kms on mine and its fine.

Strange is what i thought . U can see the deformation in the rubber ( flat spot ) on the drive side , its "squished " and not returned to original shape . I put some 2 mm sluminium spacers on each one to tighten everything up ,

Must be a bad batch of rubber but they probably made 100's or even 1000's from the same rubber mix ( if the chemestry was wrong ) stands to reason others will fail at some point .

Build date on the bike is oct 2014 10/14 .

chemistry was altered by what ever is the source of other issues like varnish look on swing arm?
