Ok I've got som fancy doodads to go on my speedo for hte Hornet. we've taken the cover off & all the screws out. But we can't for the love of god work out how to get the needle off. the doodads i'm sticking in there mean I have to remove the actual tacho which I can't do without taking the needle off. The needle feels like it won't budge - and I don't want to snap it. does it pop off or what?
