Z1B project almost done

greetings all,
Just about done with my Z1B.

The day I got it:




How it sits now:






and here's whats been done:
-Dual front disk conversion with braided steel brake lines
-Rebuilt front forks (with aftermarket damper rods)
-Rebuilt wheels with Alloy rims (Akront)
-mulholland shocks
-Full Dyna makeover
-Fresh clutch
-New Carb boots and balanced and rebuilt carbs
-Needle bearings in tree and swingarm
-Kerker exhaust
-Fork brace
-Clipons
-Tarrozzi Rearsets
-Knoscher Half-Fairing
-Corbin Gunfighter
-Fresh paint (the tank and seat are the same moro blue as my S4 in the background)

Things left to do:
-Swap out the rear tire for a better one (I have an 18x3.00 spitfire that I've been meaning to put on)
-Brace the fairing a little bit more
-Sort out the front brakes rubbing

This last one is my biggest thing... The brakes work fine however the pads don't fully retract and ever so slightly rub on the disk. I had taken the brakes apart and done a quick rebuild... but I may have to do a more thorough rebuild. First however, I'm going to see about wire wheeling the paint off the outer edge of the pads to see if that does anything. Otherwise, is anyone out there selling a pair of Z1 front calipers?

Any help would be much apprecitated
