Hi WER,
looks like I'm late for the parade on this one and you have gotten all the problems diagnosed before I opened the file.
And my mantra that chain and sprockets should be changed as a set and that everybody should run a ScottOiler seems to be well enough known that other folk's posts mention it.
A test for chain wear. Pull the chain away from the rear sprocket.
If it lifts off more than half a roller's worth, you've had your value out of it and it's replacement time.
I've only found two options when removing the sprocket retaining nut.
1) It's so loose it'll spin off by hand after the tab washer is straightened.
2) It's so tight it'll take an air impact wrench to loosen it.
Never anything between. Posts here say if that nut ain't tight the shaft seal may leak.
Note to self:- Best check that, perhaps it's not just that I've owned the bike from new that makes it drip oil like a Britbike
