Great pictures Rixington43, sounds like a fab day out.
Bike reassembled and back on charge as the voltmeter was showing 9.8v by the time I finished faffing around with the bike - still started albeit sounded like it struggled. Might be new battery time as this one is from 30 Jan 17, having been replaced by Newcastle Suzuki when my bike died in live traffic on the A1 - no hard shoulder
(They couldn't find the fault as bike started for them, so changed the battery saying the original was weak. The actual issue was the wiring loom near the frame being knackered as per the warnings of wire loom damage in that area)
Might bunk off work in the morning for an hour and give the bike a test run
