Despite having removed the rear wheel several times before, without incident, the other day I managed to knacker the speedo sensor of my F8 when I rushed a tyre change. For clarity, I'm talking about shearing off the little magnetic nub that is secured with a torx-headed bolt and reads the metallic speed/ABS disc on the LHS rear wheel hub. Bike is a 2009, non-ABS one. I've ordered a replacement from the shop, which has now come in and am debating whether to pick it up and try fitting it myself, or live without a primary speedo for 2 weeks (relying on my GPS one) and have them fit it when my bike goes in for a service in 2 weeks' time. I don't have the shop manual with me here so can't check, but I need to make a decision as to whether or not to bother going to the shop to collect it. Can someone please advise on how hard it is to fit and if there is any need for any reset of CAN BUS, etc. (as I don't have a GPS-911/similar) in order to get it working? Many thanks in advance.
