ok new (small) doctoral thesis
at least on the hayabusa (gen2 or 3) the abs block is installed almost directly on the transmission block
from there the line goes uphill to the steering head and from there
- on the gen 2 -downhill again to the right brake caliper
- on the gen 3 to a distributor and from there to the left and right individually to both brake calipers.
the zip tie trick can't work here
because the remaining air, which is still hidden in the system, can never overcome the "high point" on the steering head - without movement of the fluid - and can therefore never be released at the brake caliper via a bleeder
it never falls downhill.
THAT is physically impossible.
___________________________________________
little excurs:
in a drinking water pipe it is completely different - the water flow when tapping water pulls the air with it and thus vents the pipe if the diameter matches the amount of water flowing through.
in a heating system, a bleeder must ALWAYS be placed at a high point of a line together with an air collector
- otherwise the air bubble will remain at the high point and the heating can never work behind this high point.
when a radiator gurgles, there is air - usually at the end - in the radiator and it doesn't get really hot in that area, like in the front where the valve is located.
here the radiator is the collecting vessel.

back to the brake
only possibility, e.g. with a cross over routing over the fender , like on the gen2 , you can fool the air by completely dismounting the left brake caliper , holding it up so that its bleeder is high enough to prevent a possible air bubble from the right caliper to the left caliper - almost by itself - can ascend.
the zip tie trick only works with brakes whose hoses only lead upwards from the calipers to the master - only then can the pressure in the system force the bladder to move upwards to the reservoir.
THAT is also the reason why I ! only install two LONG steel braideds (master to saddle LH & RH) and never more a cross over lining - the (my) system vents itself almost constantly and automatically in the direction of the master / reservoir.
spongy brake by bubbles / air in the system should be now history.
greets from a german craftsman in heating ´n plumbing
plus certyfied engineer in piping etc. for heating / chilling systems.
believe me - i KNOW what issues air in pipes can cause.
