I phoned yamaha, mine should of been a 2001 by information I was given and by guides telling you about what the numbers and letters mean and yamaha told me it was a 2002 and was imported to the uk from France, I needed the information for registering it for road use so they printed it out for me at a huge cost of £45 about $60 something dollars for a single sheet of paper, most people obviously don't need that so it's just the price of a call, so if your not too sure you could try yamaha of whatever country you live in. Only takes a couple of minutes just ask for a vehicle check.
