Welcome to the forums Brendan, I hope you understand that your post is exactly what we would expect from someone who has stolen a bike and is wanting advice as to how to get it to the point they can sell it on, or from someone that has bought a stolen bike on the cheap and who wants to make it appear more legitimate. Not that I'm suggesting you are in either position but I hope you can understand why folks here might be a bit sceptical, and by answering your question we would be publicly making available information that would potentially be useful for the criminal fraternity so I'm going to suggest that you contact Yamaha UK on 01932 358000.
/Edit - Oh OK, so now you and everyone else who happens to find themselves in possession of a Fazer but no keys has the info you need from the above post which was put up whilst I was writing the above........Suddenly I feel less safe about leaving my bike unattended :groan
