ignition (key) problem.
 

So riding in to work today, I stopped for a fill up. And as I went to leave, my key would no longer turn the ignition.. Felt like the wrong key, simply would not turn.

Spent about 3 min fiddling, removing, reinserting etc, till finally it turned.

So I rode home and grabbed the car.

When I get home I will spray some WD or similar lube in there to see if that helps.

Oh the joys of older bikes :D

Noooooooooooooooooooooo WD-40! Sorry just had to stop ya. Make sure you use a proper "lock" graphite/lube. WD-40 or simalar oils will work for a short time then just gum up and collect more nasties to screw up that ignition further.

Check that the key is flat... I have once made mine slightly twisted due to not pushing the filler lid enough, and had similar problems...

Key is flat.

I have some Gun oil, and some lithium based spray.. Would either of those work? Or do I need to track down some graphite stuff?

I'd stay with the lock specific dry lube, ie. graphite type lock lube. Thats what it's made for.

Just to let everyone know.. some graphite worked great.
