I ended up trying one of these instead of the speed bleeders - Robot Check It's basically a fluid check valve with some vinyl tubing. Used it today to flush/bleed fronts and back. It worked well. I'm wishing now that I had found this thing earlier. I had installed speed bleeders last year on the FJR and that machine (with hydraulic clutch + linked brakes) takes 5 of those little jewels.
The front braking force on the V had not been very smooth. It went from not enough to too much with slightly more pressure on the lever. Before swapping out the old, dark fluid for fresh stuff, I pulled each caliper, hit the pistons with brake cleaner and worked them back and forth a few times. That plus new fluid smoothed things out rather nicely.
They can be flushed and bled with the stock bleed fittings... The trick for the front crossover line that runs over the fender is to remove the calipers to allow air trapped on top to make its way up. Holding them over each other while tapping lightly on the caliper lets all air bubbles out... I can no longer squeeze the front brake lever anywhere close to the handgrip as it was since new. Great improvement in front brake power and feel as well.
