Fausto, thats a thought. Inside the wheel is the bearing and in the sprocketholder some kind of spacer. Could be that the spacers in the holder is fitted strangely (how that could happen..) and touches the bearing too early...know what I mean..? Maybe it isnt the cuschings that is the issue, but the inner spacers...! Hmm, will check that out!

Shoot Kwackerz, Shoot!

Ok, but what was the thought?

Looking at that pic it looks to me like the cush rubbers have expanded, I had that on my Blackbird, the hub needs to be tapped in (or did in my case)

That the inner and outer spacers were swapped round on the sprocket side of the wheel.
If the outer was longer than the inner and they were swapped round then this would put the sprocket carrier and those bolts closer to the swingarm.

Still searching for the diagram and trying to confirm lengths and whether it's even possible to do

Ok you have got the spacer located properly and you would be surprised how often they have been overlooked and left on the floor

.
The gap behind the chain sprocket is not correct, the sprocket must be quite a bit thinner, is it a correct sprocket for this bike and chain ?
The sprocket bolts have a shoulder behind so it should not be possible to get that wrong. the extra bolt length looks to be caused by the lack of width in the new sprocket.
The sprocket carrier would pull in if it could when the wheel shaft was tightened but you could try loosening the sprocket nuts to see if a repositioning will get it to pull in a little further. My best guess is the sprocket has been wrongly supplied.

I think Thumper is right here. The sprocket is too thin making the inner spacings of the carrier touch the wheelbearings too early, not making the bolts protrude all the way in to the cushings.
Will try with five thin spacers for the sprocket/bolts and se if it helps. Think thats bad..?! Or should I just reuse my old sprocket ?(it really isn`t that worn out..)
Thanks for your help!

Forgive me for stating the obvious but the sprocket carrier does look like it seated right in the cush rubbers. See this.

When you fitted tthe sprocket did you align the hex bolt heads (no.9) on the rear of the sprocket correctly so that they fit in the cushes correctly. From your pic it looks like it is them what is stopping it seating right.

I know this cos I just had my rear wheel in bits to replace the bearings.

Sorry if I'm wrong.

Falcoholic, Thank you (!) for the picture!
And, if the hex bolts are supposed to be in a specific way, then they are not! Just mounted them and tightend them up. How should they be..?

Will take a closer look at the rear wheel, might be the hex bolts then, and not the inner spacers...! But I do thinkt that a thinner sprocket also could be the case though.
