Now working on block and head modifications but it may be a little while till these are completed. I need to get back in the garage as after my recent Phillip Island Historic races Ii have a whirring sound from the clutch when its depressed. Sounds like a throwout bearing which would surprise me as it is relatively new and not one of the dodgy noname ones. Anyhow the engine needs to comeout to investigate

Is it a twin plate clutch?
The reason I ask is that on swapping to a twin plate clutch mine makes whirry noises on depression
Its a single plate AP pressure plate and execdy heavy duty clutch plate. Everything works and feels fine apart from the wirring sound when depressed
