yes. 2, but the key one is this:
The HU has a self test mode. You find the ABS terminal in the rear under the seat.
Connect 2 wires (you can tell which two by looking at the shop manual for this
section. They talk about a special tool, which is really just a plug that jumps
two wires.) Once that is done, there is a procedure to cause the ABS pump to
go for first the front, then the rear. it's all in the manual.
When you've added fresh fluid, my advice is to have someone help bleed, and then
kick the bike into "self test " mode while you bleed the front, then the rear. This
will
open up a passage that normally holds fluid in reserve and will flush it through.
It only self tests each lever (front lever, then rear pedal) for a short moment, So
I would do this several times front and back to be safe. Anyone have any other input?
Part B: Front caliper. I believe this thing has to be brought forward to be bled,
since the bleeder is
not in an ideal position. Yamaha has some dumb tool to allow this. Someone probably can
suggest a better way. Speed bleeders might help (little one way bleeding valves that
take
the place of your normal bleeding valves).
What do y'all think?
