Getting bike engine through SVA?
tegwin - 5/2/08 at 10:41 PM

I know some people have had a few issues with this...

so....

If I bought say, a 2001 ZX10R with injection, would I be likley to pass the emissions test if I use the standard inlet, exhaust system and stock ECU?


If, to confuse things, I got say a 1992 ZZR1100 which is on carbs....how hard would that be to get through SVA?


Any insight into bike engines and SVA/settup would be greatly appreciated.

I can only speak for an ancient ZZR on carbs!
Passed SVA emissions second time around.

Using standard ECU / CDi, standard carbs and needles. Just took it along to my local friendly garage first, hooked it up to there emissions tester and leaned out the mixture screws at idle.

The standard exhaust system would look pretty silly sticking out the side of the car and up!!

Have you searched for this at all?? There are loads passed with an injected engine with the addition of a Powercommander and Catalytic converter in the various manufacturer's kitcar exhaust system.

as soon as the bike engine is in a car then it is subject to the same emisions as a car, so pre August 95 they need to meet 3.5% co and less than 1200 ppm HC which any well set up engine should meet be it bike or car
After aug95 it needs to meet CAT emmisions so0.3%co at 3000rpm
less than 200 ppm HC and less than 0,5%CO at idle
Carbed bike engines can be made to meet this but are a bit of a bugger to set up where as FI bikes with a power commander fitted are much easier to tune to meet the needs of the cat converter which will be required

Even a stock bike engine with all its original exhaust and airbox etc will not meet the emmisions neede at SVA without a proper cat converter and a good setup of fueling

perhaps put a car engine in for the SVA and then the bike one later?

I would, but there is no way on earth im ever going to be able to squeeze a car engine into this chassis!

My Fisher Fury has got a carbed 1997/9 Blackbird engine in it. There's no cat and it has successfully passed SVA and subsequent MOTs since being registered in 2001. I understand that it doesn't need an emissions test - though I may be wrong?
I'm only just up the road from you in Cradley if you want a look at the installation some time.

back in the early days off SVA you would have got away with no cat test at sva but it would'nt happen now, they have wised up to bike engines etc and its up to you to prove its to old for a cat test

After registration a Q plate is in theory a visual check only for excessive smoke only as it is tret as a pre 1971 vehicle

I passed without touching the carbs to tune them at all.

Mine failed miserably at emissions time the first time around and funnily enough the fix was to sort the HT leads properly.

Made up proper copper leads with soldered ends and it sailed through without any probs at all - I think it was 900ppm HC and 0.5% CO (will check if you need the data).
