I picked up a "new" master cylinder with remote reservoir from China cheaper than I could get a used one, mounted it with a stainless steel hose from the master to the caliper, and it works fine but the piston doesn't retract fully. I rebuilt the caliper but I still get drag. So I made a tool to retract the piston from a piece of 1 1/4" tubing that encircles the banjo bolt. Pushing on it forces the piston back into the caliper, then pulling on it slightly creates the clearance I need. Only drawback is that I have to pump the handle 2 or 3 times to get the brake back. This should be OK unless a moose runs out in front of me at Loring next weekend, in which case they don't make brakes good enough to save me anyway.
I sent the rotor down to the only machinist in town capable of grinding it in hopes that the reground rotor won't need as much pushing & pulling to get clearance.
I also had to bore a hole in the rear fairing to access the caliper with the new tool or I would have to remove the rear fairings to do so.
Looking forward to next weekend, although I haven't done much to the motor this year. Changed the timing a bit and I'm going to try the ram air airbox again with all the vents hooked up to the airbox. I found out I have to seal off the keyhole in the gas filler cap to seal off the tank, which is also vented to the airbox.
