My problem is that my barn find F1 had the insides of the lock rusted to where the key wouldn't turn, like everything else on the bike. I was able to take the switch mechanism apart part way, but could not get all of the rust cleaned out. My switch is working, but turning the key gets very stiff and the key needs to get "jiggled" until it makes contact sometimes.
I hate the thoughts of paying over $200 for an OEM switch, if the other will work.
