Need some advice please. K8 Busa standard been stood for a month or so battery went flat tried to start and gauges stuck Speedo and rev counter and no digital display fuel and temp at max. Managed to get the battery back into life and start bike. Gauges still stuck with no display. Disconnect battery and all gauges now back to zero. Bike starts although sometimes stalls at tickover. No gauges work or display but everything else works ie neutral light indicator high beam. Fuses all ok Any ideas ? If I replace battery will the dash reset ?
