When i built my F27 with a ZX9 motor in it i wondered why it had to pass car emissions test also,but it is a car no matter where the engine is from.
Anyway i failed the emissions test 3 times and got real pissed off with it all,i even had the company recommended cat in it.What i did was get the emissions set up properly on a gas analyser and it passed easily,so dont give up because the first time you drive it all the dramas will disappear in an instant.

Spud,do you know something I dont ?

Ive put two cats in the exhaust system now and its not made any difference.
I dont want buy a power commander and have the hastle of the rolling road. The engine in the car is nearly brand new its only got 1,500 miles on it and thats also more cash i need to through into it.

Hello Mick,

Track day at teesside is usually £95 for the day inc breakfast and lunch, they are very easy going and i've never seen them bother with noise reg tests. The one planned for the 1st April, hopefully, is a track day to setup the track day, the man behind the project is hiring the track for the day and there should be room for other cars.

FLYERNCLE, we where both there on Saturday afternoon when Jim asked when the car will be complete - you did say end of the month and he replied "right i shall book the track for 1st April" You said it....... BTW i'm doing a new set of white bodywork (exc bonnet which you've got) this week. The painted second hand body he had looked crap - we don't want that on the car.

Regards....Andrew

Thanks andy im gona try to get a loan of a trailer to get it down there if i manage to get a trailer youve got to have a go of my car. I think you'll be impresed with how qiuck it is from 0-60 its a beast of a car. Im gona try wraping the cat with heat wrap and use a few of these lads ideas to see if i can keep the cat hot as a lot of people are saying that the cats not getting hot enough.

what you running engine and fueling wise i would be surprised if you could not get a bike engine thu a cat test you would need to have some form of fuel inj running closed loop lambda (narrow band would be ok)
megasquirt/microsquirt springs to mind
if you have say a newer bike engine it would have inj and a sensor in the exaust it should get through ok

thing is with cats is you have to get the fueling fairly lean to get good gasses out
you would need your pre cat co less than 0.50 to have any chance of the cat dooing its work and have it close enough to the engine to get hot enough to work its magic
this will be almost impossible with a carb setup in my opinon
as you not only have to idle but fast idle bit of the test too

I had the cat just past the primaries and had the mixture leaned a bit to pass the emissions,this was all done on a gas analyser with a zx9 motor on carbs and passed easily.Just takes a little know how on behalf of the person setting it up for you.
