ignition switch


Post by kk1340 » Tue May 25, 2010 9:10 pm

i was wondering if it is possible to switch out the key tumblers on a 1963 switch. i have to replace the old one but want to use to old key as it works the fork lock. also where is the the best place to buy a replacement switch. the old one is doing crazy stuff. i can move it around and get different lights to come on. when i turn the bike off the gen light stays lite. any help would be great. keith

If your lock is original you can rebuild it. None of the current aftermarket switches use the old style tumbler. And they are all pretty much junk. Turn your lock upside down and you will see a brass roller bar held in place by a a spring loaded steel pin. If you pull the pin towards you it will release the bar. The contact plate is then removable. Beneath it is the locking mechanism. Often you can make the switch work again just by rotating the roller bar 180 degrees to provide a new contact area. I would try to fix it or look for an old original but would never buy one of the repop junk!

in addition to robbies suggestion check the terminal plate for loose rivets. you can repeen the rivets and get some extra life out of an old switch.

nos replacement bars and terminal rings do show up on ebay occasionally.
