Sorry if this has been discussed before, I have tried searching but the function seems a bit limited (unless I'm doing something wrong). My 7 (08 CSR) has a really annoying transmission whine when the throttle is being feathered (disappears with no throttle or when you are starting to push on) I had a chat with Road and Race who had recently rebuilt the diff, their view was that this is caused by the engine being slightly inclined, and they thought that somebody in the past had made some spacers for the gearbox that remedied this. Does anybody have anymore info? Thanks G
