2002 RSV Mille. Bike starts first time all the time even if left in the garage for a few days but now and again after I stop and try to restart, such as after filling up, the dash resets and a slight delay before starter turns. Changes to kmh, clock back to 00.00, rev limit back to 6k. Probably going to change the battery anyway but is there anything else to check? Voltage on dash usually 13.4 v.
