My mate's yz450f has a 13mm allen key slot in it. I'm in Saudi Arabia. You can't even specify 13mm bolt heads here, never mind find a 13mm allen key! Has anyone got a good idea as to what I can use to get the cover off? Is there something on the bike that, presto turno, you can get it off with? I am going out (again) tomorrow to try and find a 13mm hex bolt or similar to get the bugger off, but any great ideas in the meantime would be much appreciated. And what was wrong with the big straight slot they all used to have in the first place?!
