Master Cylinder

I've had great success "reverse bleeding" my brakes.
1). empty the master cylinder.
2). fill a 20 ml syringe with brake fluid.
3). open bleed nipple.
4). connect syringe to bleed nipple with plastic hose/tube.
5). SLOWLY inject brake fluid into system until fluid appears in master cylinder.
6). close bleed nipple
7). top up master cylinder
. squeeze brakes a few times.
9). go riding! :woohoo:

Nope,just pump lever a few times and wrap zip tie around it and bar.
You might try cracking a bleeder valve in first thing in morning with lever still pulled in to see if a big air bubble comes out.

Retaining the 14mm master cylinder used with a single front disc, and adding a second front disc, will typically increase the sensitivity of the brake, whereby the former squeeze effort with single disc will produce a significantly increased braking action with dual discs.

Such increased lever sensitivity may be all right where the rider has become acclimated to it. But there are reports of riders being surprised by the increased braking response, such as front wheel lock-up (especially in reduced traction situations, such as wet road, damp leaves, sand, gravel, etc.), causing loss of control and tip-over.

Kawasaki had reasons for using a larger bore master cylinder with introduction of dual front discs, and it wasn't solely related to providing additional fluid for the second caliper.

A super-sensitive front brake could pose a risk to a novice rider who in a tight situation instinctively grabs and squeezes the brake lever with all his might.

Good Fortune!
