Replacing Chain

[Dead Eye]

So had some fun with not being able to get the chain off nor the swingarm and ended up asking for the assistance of tony22 whom ground off the rivet heads and then finally managed to remove the old chain

So, new chain fitted, sprockets changed and rear wheel back on BUT I can't seem to get it to align correctly. The wheel is effectively pointing to the right hand side of the bike if looking at the wheel from the rear of the bike. There are about 5 adjustment marks before the washer on the left hand side and more like 8-10 on the right but I can't get the right side to move forward and line up equally. I tried some persuasion with a hammer, but it doesn't want to budge I have made sure there is ample room for it move in regards to the adjusters.

I'll try and get some photos up to illustrate
