[QUOTE="John Fewster, post: 129359, member: 4168"] Blowing ferrule joint with return pipe A58. Problem came suddenly. I started bike after few weeks off and noticed the oil return pipe A58 along with rubber section to rear rocker feed was pulsating like a vein about to burst. Never noticed this before. It settled down after a few minutes and I made short test drive. When I restarted, the pulsations pushed the rubber section clean off top of return pipe A58 and the junction with A68 to rear rocker feed banjo. Stopped immediately since oil was peeing out. I have since blown out with airline (no blockages found) and removed all rocker feed banjos and re fitted all new washers etc. Very easy to blow through pipe to tank so positively no blocks. Re fitted all the rubber sections of hose (slightly longer bits) all de-greased and hylomared. Standard push fit (not crimped) ferrules as have been in place for years no problem. Started up. Oil pumping through to tank return straight away no problem... BUT return pipe still 'throbbing' and after couple of seconds oil seeping copiously from ferrule joint top of A58 return pipe!!! Help! - John Fewster [/QUOTE]
