So I contacted Yamaha UK, and because mine was originally a US model it was never tested. The BS of it all is the US/UK/Euro versions of the FZS1000 are all the fucking same in the carb, ignition dept.

Avoid going down this route. Yamaha won't issue a certificate if the frame has been changed.
Better off waiting to see if TFL will exempt the whole model
