Hello.
I am still fighting the fight for emission requirement change in Vic Australia. Making progress with high level meetings.
I understand that the UK may of changed its requirements for emissions.
May some one please tell me what the requirements are and where I can source the official information.
Ideally if there is a fair method being used in other areas then it is seen to be better than just making some new method up
for us putting a new / modified / kit vehicle on the road its the Individual Vehicle Approval (IVA) rules that apply for cars and Motorcycle Single
Vehicle Approval (MSVA) for bikes
and all the requirements are all laid out to be fairly easy to follow in these manuals:
Cars: (regardless of engine source - so includes bike engined cars)
https://www.gov.uk/government/publications/iva-manual-for-vehicle-category-m1
Bikes:
https://www.gov.uk/government/publications/motorcycle-single-vehicle-approval-inspection-manual
the emissions bits have flow charts that you just have to follow thorough based on the engine age
(assuming you can prove it - without proof you have to meet the newest standard by default)

Depends on the engine really...
most car engines are fine if you can prove the age as your only testing to the same standard as they needed to pass when they were new
Some bike engines can be a little bit tricky as they didn't have to meet the same standards as the cars when new, eg. A 2001 zx9r was still
running on carbs so getting it to pass a catalysed test has its issues 
(That's why a lot of people build the car with pre-Aug 95 engines)
An injected bike engine would be easier than a carbed. Having said that I got a 1998 carbed XZ9R through IVA and it passed with post 2002 emissions
with a 200cell cat

I believe the answer is yes, with a carefully tuned Power Commander controlling the fuelling.
