Next steps.
Ordered some exactfit belts and tensioner bearings. Pick up battery, filter and oil locally.
Blow carbs through just in case, oil and filter change - see how she runs.
If that's successful, change brake fluid and chance an MOT.
I think the chain and sprockets may need a change or maybe just the chain (I know but dicking around with gearing has got them out of sequence).
When's the next WDW?
