Have any of you taken an ignition switch apart? Mine seems to work once it is in the on position however sometimes it takes a bit of key jiggling to get it to do so. I don't fancy having separate keys for ignition, petrol cap and seat lock. I guess my options are to try and take it to bit's, I have visions of lots of springs and other parts flying all around the garage. Or I could just buy a full set of locks. What would you all suggest? Is it feasible to rebuild one myself, as if it is on it's way out it needs to be sorted.

Mine needs a bit of jiggling and playing about with sometimes, especially when it's cold.

Never bothered me enough to sort it though.....

I could just live with it then if it is a common problem, just didn't fancy having it go on me. I'll try copious amounts of WD40 see if that helps.

Mine spent years being a case of having to try several times before it would turn. Didn't matter if I used the genuine key or a copy that I had as a spare. I got so completely fed up with it that I decided the next time the bugger played up, rather than tell myself the next time it played up I'd replace it and never get around to it, that I'd simply give the thing a huge heave and myself the satisfaction of having killed it and being rid of the bloody thing. That time duly arrived, and after using rather a lot of force, it switched on with a loud crack. Oddly, it wasn't broken, and has ever after operated better than ever before. Thinking about it logically, I wonder if it can now be turned on by sticking anything in it? lol I wouldn't recommend forcing yours in case it breaks in a less than useful manner!

Try a bit of dry graphite powder to lube the lock insides, might not get rid of the problem but will help.

I bought the Chinese lock set £30 delivered. Unsoldered the wiring from the new switch and soldered old loom to new switch works great

Cheers for the advice from you all, much appreciated.

The electrical switch contact part is held under the main mechanical body with 3 or 4 torks security screws.
Remove the switch [2 tight Torks bolts] and take the contact part off and replace with new or secondhand, the key fits the upper part, electrical part is the same.

If the 2 shallow head Torks bolts are too tight [they are thread locked] then remove the top yoke and clamp in vice to undo them, if you round off the heads, removal will be a long job.
