Hello, new to this forum. I was trying to bleed my VFR800 1999. I blead the front right caliper outter nipple and it blead fine. I blead the front left caliper outer nipple and it blead fine. I blead the front right caliper center nipple and it blead fine. I blead the front left caliper center nipple and it blead fine. I tried to bleed the PCV nipple but no air or fluid would come out. I tried to bleed the rear caliper center nipple but no fluid or air would come out. I blead the rear caliper outter nipple and it blead fine. Any ideas why it wont bleed, I'm thinking there might be a blockage in the line.
