2 weeks ago I left the oil to drain out of my C5 in my workshop, today I replaced filters etc and put fresh oil into the engine. Whilst the bike was still on the Hydraulic bench I was standing on the right of the bike and started it, there was the most horrendous noise until the engine was running, I only get this noise intermittently, and pretty sure they are coming from the left hand side of the engine, surely with less than 8000 miles on the clock its not the Sprag clutch? I am hoping that once the fresh oil as got everywhere it will cease to make these noises or am I dreaming?
