I was one of the guinea pigs for the GG's. I first started with a Magura Master Cylinder, and had nothing but problems. Then Allen came up with the window fix for our MC's and things went better. Make sure U back bleed the clutch. This is key.
Allen sent me the shims and a new knob with a packet of special grease. The grease eases the turning of the adjustment knob and lubes the O-ring. He actually walked me thru the adjustment over the phone. Good luck. Let us know how U like it.
