just replaced the switch in my 77 550f and rode my 650c to work. The 650 is still in shakedown mode but runs good, normally. Guess which bike now needs a switch, I think. The lights come on in between the switch detents. cannot get it to stay on. Runs great if you hold the key so the lights are on. Will see what I can do after work. Ordered a new switch on ebay. Any suggestions on jiggling the switch ar wiggling the wires? Atleast I am not 7 miles from the nearest exit in the pouring rain.
