Hi 
You can check the part numbers for each model year here to confirm if the ECU is the same. I have a suspicion that they changed at some point in the production period. http://www.yamaha-motor.com/sport/parts/home.aspx?sb=4
I'm not familiar with Japanese market restriction methods but is just a lower gear-only thing? Have you looked at this sort of solution? http://www.ebay.co.uk/itm/Nikko-De-Restr...5192cdb777
