Hey guys,
Thanks for the replies and info. I’ve been studying what has been said and really wish I had the knowledge and confidence to pull the gearbox out, but looking at options before I end up I’m bigger strife than I already am.
Limeyrob, I assume the only way to get to the sprocket nut is with gearbox removal, and certainly to get an extra spacer in there it would be required. Looking at the exposed diagram, it looks like the sprocket is on a ‘machined collar’. If this is the case, how does this go with moving the sprocket towards the gearbox casing? Is this not a predetermined distance to marry up with the shaft? If it is a case of moving the sprocket away from the rear of inner primary case and the gearbox spacing remains constant, does this push the primary case outwards, affecting the alignment of the clutch/primary chain/casing?
I’m really confused by this, as I said without the knowledge it’s hard to take the leap of removing the gearbox.
I have removed the rear wheel, loosened everything off etc, it’s pretty obvious that wheel alignment plays no part in this, as I was hoping, the distance between the sprocket and the chain hitting the casing is close so it has very little opportunity to move away from the casing.
I have checked the chain, it’s a standard chain, so no movement there.
Cheers Craig
