Could someone identify the switch and its function on the right hand side between the starter button and the engine kill switch. I have no manual and cant find the info anywhere, The switch has a dipped light and arrow on it and I expected it to be a self returning head light flash switch, but this has a definate on and off position and nothing seems to happen when I move the switch. please advise as the bike is new to me so Im still finding my way round it all. Cheers
