Yep, suffered this on the IOM. Martin, the sender will (if CC haven't changed it) light up (at the back where the cable exits) as the teeth on the ring pass past, my new one seemed to be quite relaxed on the position (ie it worked with up to 4mm gap) I'm on call this weekend and am picking up the new Motor on Saturday, but if you want to come past on Sunday, we can take the sensor off mine and test if you like? I'm also 1/2 days most of next week, so can do then too. I had a tidying session in the "Mancave" aka Garage up, so we can work in releatve comfort with both 7's under cover!! Mike
