If I put my key in the ignition switch, my steering lock is sometimes reluctant to come off again (goes on no problem, and putting it on "park" with sidelights is no problem either), and sometimes sticks slightly (though to a lesser extent) when turning the ignition on (does it with both black keys). FWIW, I do have a fairly hefty bunch of keys.
Other locks (seat) are no problem.
At the moment I'm reluctant to simply spray WD40 or similar down it (fear of damaging the immobiliser transceiver).
Anyone else experienced this problem? Its a 2008 Fazer 600 S2 ('58 plate).
