I don’t know if this is of any help but I had a problem with my speedo and trip meter when I used my bike for the first time after a lay off over Christmas. Both speedo and trip were significantly under reading. I e-mailed John Drogan directly and had a quick response from him saying he had passed the information on to Steve.I had an e-mail from Steve within half a day telling me one of the technicians would contact me as soon as possible. The following day Ben rang me to discuss the problems. He talked me through the settings in the instrument panel and found one that wasn’t as it should be. It was easily corrected following the technicians clear instructions and everything was sorted in 48 hours.
Might be worth contacting Steve or John directly and try and have a chat with one of the technicians.
