R1 Sprocket adapter free play
Should there be any free play once the sprocket nut is done up?
I've torqued the nut up to 86nm but the adapter can slide forward and back a couple of mm.

It shouldn't move, i was told by ST that if mine moved i should use extra lock washers to pack it out, as it was there was no movement anyway.
Better to be safe i reckon, as it shouldn't be too difficult to make it lock on solid.

No movement at all...
It needs to be spaced out using spacing washers or rings to enable the securing bolt to 'pull up' tight. Removing the play will stop
inevitable vibration and the chance of the bolt working loose.
The last thing you want is a long piece of tube wizzing round at a million miles per hour inches from your legs...
Make up a spacer - our's was 1.3mm wide FTR

Yep you definitely do not want movement! Ive heard of several sprocket retaining bolts breaking because of loose / ill fitting prop adapters, I guess
because it could in certain circumstances almost act like a slide hammer and whack the back of the bolt

Check that you have the sprocket retaining nut on the right way around.
Genuine Yamaha nuts have a counterbore of a couple of mm on one side. This allows clearance between the shaft spline and the sprocket face,
effectively allowing the nut to lock the sprocket on the shaft against the back face, before any interference issues.
If you have an alternative nut, then a spacer may be needed.

That was exactly the problem.
Turning the nut the other way round gives me a rock solid adapter.
