Yeah you need to be wary turning it over when the battery is that flat- that clicking is the solenoid getting very close to not returning so it would stay making contact trying to turn the starter motor after you’ve released the button, at that point you risk damaging the sprag clutch.

Incidentally, in my experience as long as the motor spins up fast enough i.e. with a fully charged battery, good ground connections and assuming the vacuum tap and fuel pump are both working properly then they should fill the float bowls fairly quickly- we’ll within three ten second presses of the starter.

A couple of years back when I did a little refresh where I replaced the fuel lines and said vacuum tap/pump my bike started almost instantly even with it having to prime it all with empty carbs.

It’s looking really good by the way- credit to you!
