- In this part, I deviated from the manual in a few ways.
1) I conducted the battery charge test off camera (simply using a multimeter-- it was fine)
2) as mentioned in the video, I did not compress the calliper pistons in the front like the manual calls for (I cannot seem to find my compressor)
3) I did not bleed the front master cylinder , since my bike does not have a bleed nipple at the top like the 2011/2012 models did
Also - i did not install the speed bleeders up front because the size sent was too small, and I only realized this as I tried to screw them in.
Regarding compressing the pistons- the reason we do this is to squeeze out the pooled fluid in behind all the pistons up front. A simple bleed like the video shows doesn't scavenge out that fluid well. The manual has you remove the brake pads, then compress all the pistons back into their bore after you empty the reservoir up top with the baster. When you do this compression it will squeeze old fluid back up and probably fill up the reservoir, which you can in turn draw off and dispose.
You keep the pistons compressed while you do the actual bleed, and then afterwards put the pads back in and pump them out with the brake lever..
It is a good idea to do this extra step, and i will re-bleed the front when the proper sized speed bleeders arrive.
The entire service can be relatively quick , (maybe an hour and a half if you are very fast and have done this before), but I would plan on a morning or afternoon when you include clean up and unforeseen interruptions.
