Wheel bearings were easy enough, water had ingressed into the hub void and eventually fubarred the non-drive side bearing. The internal spacer has some nice cutouts to allow a drift to fit easily. I also found about half a dozen buried flints and 2 bits of metal stuck in the tyre that would have eventually worked their way to becoming a puncture.
With the rear end dismantled for wheel access, it became obvious why the winkers were dud:

That's my brand new wiring loom too!
So 2 new cables and some amalgamating tape later that job's done.
The exhaust has to come off for the rear wheel spindle to be removed, this revealed some new holes had appeared in the underside - I swear this silencer is now mostly brazeing rod. After a run over with some fresh engine enamel it's back in place again.

Generous applications of Plastic Padding 'Leak Fix' to the tanks undersides and some deft filing repairs the leaks.
Ready to fight again for another few months.

Just finished before the rain started too!
Happy days
Dave
