Hi Dazza, I gave you the wrong info! It was Yamaha UK i contacted regarding the origins of the bike. I tried the dvla first and they were utterly useless. Yamaha couldn't have been more helpful 
Yamaha UK - 01932 358000. The bike makes approx 25 hp more once derestricted and makes a BIG difference. It's really easy to do. The only thing you need to be careful about is on one of the inner carb tops (No 2) there is a tiny o ring that can pop off. My bike had been in the UK for years and nobody had checked to see if it was restricted :rollin It was a great feeling removing the restrictors and letting her loose for the first time!

If it's broken, it's not fixed.
