Hi All,

My powervalve coupling has fallen off entirely and gone back through the fan at Towcester. Does anyone have a spare i can buy? In the likely event I've used the wrong term, it's the bit that holds the power-valves in the two cylinders together (the bit which you can see at the side of the engine which cycles when you switch the power on if you have the valve servo controlled.

Any ideas (other than not to have undertightened it in the first place) welcome!!
