Best way to sort R1 emissions
StevieB - 5/6/08 at 09:35 AM

Hi all,

whats the best way to sort my R1 emissions for SVA - thinking cheapest and easiest to sort out for every MOT.

Also, how have people addressed the cat issue?

Cheers

Steve

by fitting a cat?

are you injected or carburetter ???

I opted for an injected R1 with a power commander. This means that I can have a map for the mot.
Cats will be required on any engine made on/after 1995.
I bought mine fron a USA supplier on ebay for £50 including delivery. MK engineering do the same one for £80.

I got my carbed R1 through by fitting a cat and adjusting the idle fuel mixture screws at an MOT station until the readings were right.

I'm running a year carb'd 5JJ engine.

I'd seen the cats on ebay and was wondering how to tackle the slight kink that's in my exhaust - maybe it's worth the bit extra for the MK version of the same thing, assuming that it can be suitably fettled to fit.

you will probably have a dynojet kit in your carbs ??
iyour best bet is to have a cat made or altered to suit your car ( doesnt need to be stainless for mot time get one off ebay ) and a spare std set of carbs ( i.e std needles, mains etc ) and just swap over for mot time.

Cheers - I've got a set of TTS BEC needles in the carbs already, it was more the cat and setup that I was querying.

I'll have a search on ebay and see if I can find mild steel cat to use (at least then I can get it fettled with a mig welder by my mate)

Any particular car that would be suitable to source one from?

id be suprised if it will pass emmisions with those needles in you need std ones normally

any cat fitted to a 1 litre or upwards engine will do the trick,
once you have got it fitted have a run over here on a saturday and you can hook it up to our gas analyser and see if the tts needles will pass emmisions

cheers
