Behind the left hand side panel appears to be a relay that has a permanent 12v live going to it, live even with the ignition switched off.
Can I wire in a permanent Optimate lead here or, will this electrickery canbus wizardry throw a wobbly and tantrum if I do so?

don't know about the specific bike but it looks to me as if there are 2 big wires 1 will be from the battery and 1 to the component it operates. The 2 smaller wires are to control the relay so I can't see you would have a problem joining into the larger wire via a fuse.

Probably a good starting place to get a feel for how the electrics are laid out before you go experimenting too deeply.
