Dene,
as far as i have been able to find out , you cant transfer he certificate to a diffrent bike or all you'd have to do is find someone with a kit fitted and "borrow" there certificate.
the certificates contain infomation unique to the bike tey are fitted to eg reg number frame and engine number etc..
the only ay you can get proof of restriction is a trip to a local dyno center and get them to certify the bike as 33bhp
If anyone knows any different id love to know
cheers
Andy
