Quick update, the noise is still there. I have cleaned everything, replaced the push rod, top hat and pressure plate bearing. As soon as the bike hits 3500rpm it starts and stops around the 4k mark. High pitched wah wah bloody wah. It's doing my head right in, its that sort of rev range that you have when you are just coming into town or pottering in low gears through traffic. I'm used to people looking at me like my bike is broken but this is taking the pi$$. I don't know what else to try. At the moment I have a non-standard pressure plate with one of those star shaped spring retainers so I guess I could try changing all that back to the factory plate and spring cups. For a change, the rest of the bike is running really sweet so this is taking the jam out of my doughnut.
