Emissions

My Cafe Racer is fitted with the short sport "silencers" and has been remapped to suit. In a couple of months it is due for it's first MOT and here in Germany an emissions test is part of the MOT. I realise I will have to refit the original silencers but the question is: will the remap have affected the emissions to such an extent that it will no longer pass the emissions test (Euro 3)?

I have asked Norton about this and Ihave only received a very unsatisfactory answer so I'm throwing this out to the panel.

Will it be possible to have the bike emissions tested with the original pipes fitted prior to the MOT? I suspect that may be the only way to get a certain answer on this one.

Thanks Lee, but that is one option I was hoping to avoid, as the MoT testers here have the power to declare a vehicle un-roadworthy there and then and scratch the MoT stamp off the numberplate. Whether they would do that or not is an unknown and not a chance I really want to take.

It will depend on the remap and the standards its tested too, last UK MOT on my fuel injected car with no alternations showed its emissions as 95+% below the permitted max's 120K miles and 10 years old.

Thanks John, there's maybe a ray of light there.

I took the 961 to the MoT today and it failed the emissions test. The test showed a 7,5% Carbon Monoxide content, the maxium permitted content is 0,3%. Further use of the bike is prohibited till the fault has been rectified.

You can't win with these technocrats, they make new vehicles wear a cat converter to turn the Co into Co2 and then they claim the extra Co2 they enforced is causing catastrophic warming. Barmy...

Still, it keeps a few jobsworthsoff the streets and on our backs!

Hope you get it back on the road soon David.

Sounds like you need the bike re-mapped to original! Did your Local dealer do your re-mapping or was it back at the factory in UK.!

I suspect that is what the problem is. It was remapped at the factory at the first service.

I've fitted the louder longer silencers (the ones looking like the originals)without any remapping - bought and fitted myself. Bike runs fine and after asking Norton whether it really needed remap they said if it's running OK , leave it. When the time comes for MOT plan to just swop back to original silencers to cover emissions test.

So I guess my real question is can you re-map locally or do you need to go back to UK then home for Mot then ???

My bike has the latest closed loop fuel injection which I believe is compensating for the sport pipes I have. It runs great but I never tried it stock!

I've been in touch with a dealer today who assures me he can get it through the MoT. At the same time he is going to carry a service (2 yrs).

It might only be me but I think it runs better with the present map and the original pipes but it's much too quiet. In hindsight I think it would have been better to have bought the long open pipes and have left the mapping standard. Experience is something you get just after you really needed it!
