Despite the threads on the subject, I can't quite get my head round what is needed.

Have an Indy on a G plate, no emissions on the V5, no CAT and its a 2003 R1 (injected). Car originally had a GSXR engine in before it was swapped out for the R1 (before I bought the car).

Had a "friendly" MOT man before but he is not available this year and the two nearest garages to me had no idea how to put it through.

What emissions test will it need and will I need to put a CAT exhaust together? AFAIK the 2003 bike didnt have a CAT?

I would of said whatever it lists on the V5.

If you have declaired your engine swap but they haven't changed the emmisions on the V5 its their loss!

It would get tested as a G plate I'd assume? 1989-1990, so 3.5% and 1200ppm according to http://www.motuk.co.uk/images/7.3page6.pdf

mines on a "N" visible smoke test.

edit to add 74 N.

3.5co% and 1200ppm HC

Ta all. Will it make that without a CAT ok?
