I sold my RR8 recently.... they guy mailed me tonight and said the rev needle has come off ?? I've never read or heard of this happening anyone had or know of it happening elsewhere ?? His concern was that clocks might be from another bike......do replacement clocks read mileage from ECU or show previous mileage as they were removed ??
Clocks keep the mileage, tell him to go to: https://www.gov.uk/check-mot-history there should be a record of mileage on there that should put his mind (and get him off our back) to rest.
