I should add that was 13.7V with moderate revs I couldnt tell you how many revs as i dont have a tacho!
Thank you for your input I hope so. Im going to start methodically checking connectors starting with the one behind the battery for the RR, and then work my way around the loom (again).....all while hoping someone has a lightbulb moment for me!
There's a 19 pin connector on the right front of the bike that is a known source of problems. Give that a clean with contact cleaner. It's where the front harness connects to the rear harness
