Has anyone tried to clean or repair a handlebar switch? I traced the cause of my headlight not working to a faulty OFF<-->ON switch at the handlebar. I was thinking of removing the small metal plate above the sliding switch to maybe try to check / clean the contacts but am worried that if removing it springs / ball bearings might fly out, probably never to be found again, (as happened to me many years ago with a Fizzy Yamaha). I have been looking for a while for a second hand replacement but there haven't been any up for sale, any for sale are all left hand switches not right hand switches, (1981 CB100N). Thanks.
