Strictly speaking with any branch system you should start on the longest leg, so in the case of a Fazer's front the left. But as mentioned it makes little difference, as the branch is just a tube. That said I always do the leff first with standard lines and give the branch that joins to two lines going down to the calipers at few taps during the process, while the leaver is in the at rest (fully forward) position. This will help push any trapped air up and out of the master cylinder
