Howdy.......sportster XL883C and something wrong with master cyl on rear. Won't pump fluid. Looks like new. Fluid clean and clear. Removed discharge line from Master Cyl body and it still won't pump. Acts like it is not getting fed, but removed res. hose and fluid pours out ??????????? Anyone ever worked on one of these? Thank You ..........Pete/MS PS: Master Cyl (on rear) is metric !!! First nuts and bolts I found on bike that are metric.
