beats Posted September 13, 2006 Share Posted September 13, 2006 The pump on my '90RR is intermmitently noisy. When the accumulator bleed screw is opened the noise stops but once tightened the noise steadily increases. It (the racket) seems to coincide with fine air bubbles which are in the system. I have replaced the pump and accumulator but the symptoms are the same. Any advice would be appreciated! Quote Link to comment Share on other sites More sharing options...
Highway_Star Posted September 18, 2006 Share Posted September 18, 2006 Bleed, bleed and bleed. Mine was like that until I got all the air out, bled using a Gunsons pressure bleeder and following the instructions in the manual to the letter.
