Technician from the dealer got back to me today, as they didn't get to look at it on Friday.

They're replacing the clocks and entire wiring harness under warranty as they're badly corroded internally. Water ingress into the back of the clocks via the connector, the right hand switch block (hence issues starting), wiring harness connectors at left of fuel tank and relays.

Bikes never been pressure washed by myself but I do use it Mon to Fri every week for the last eight months.

At least I have way forward. :-)
