Is the K1100 fuelling system capable of being euro 6 compliant, and if so, what needs to be done, costs etc

I really love the K100/1100 bike, and am reluctant to spend money on a newer bike just to 

comply with tightening emission laws.

I am taking my K100 to an mot station to get her "sniffed" just to see how far away she is  from current euro 6 

requirements.

I think the US versions of K1100s might do OK since they have a catalytic converter but I think the Euro bikes were non-cat.

It's easy to tell if a K1100 has a cat since it will have an O2/lambda sensor mounted in the exhaust on the top under the left peg plate.

Thanks for that Duck.

Is there information on K1100 emissions with a cat fitted , with regards to being euro 6 compliant.

Also, could a UK K1100 be converted

I am not aware of any difference in the engine management as in the Motronic unit.

A US exhaust with the lambda sensor in it is easy enough to get hold of, question is: is that a plug and play into a European model. I have little doubt about the physical fit- just get new rubber mounts and exhaust gaskets.

Not aware of any other items apart from making sure air filter is good and injectors in good shape.

There are cat and non-cat versions of both K1100 Motronics.

13611464649 Early Cat
13611464479 Early non-cat

13611464717 Late Cat
13617651599 Late non-cat

And the non-cat bike wiring doesn't have wiring for the sensor.

I've never tried it but you'd need a different Motronic, engine wiring harness, sensor and cat exhaust.  I THINK that the main wiring harness is the same though.

I don't know any numbers but I imagine it puts out less nasty gases than a non-cat bike.

If you look at the K1100 US marketing literature BMW was very proud that it was one of, if not the, first production bike with a cat.

Early K100 has a fuel pressure sensor [as well as regulator] that has a vacuum pipe and an electrical connection. Removing it and blanking the vacuum pipe has no effect....

I wonder does the EU Motronic have a similar situation with the Lambda sensor but definitely needs to be checked. Anyone access to part nos? We already have odd ones in EU, I think Swiss or Danish Ks are tuned down and use different FICU/Motronic units.

Odds are main loom is the same with just a plug in for the sensor.

Ks have two wiring harnesses: one for the engine (that connects to the L-Jet or Motronic) and a main one for everything else.  The engine harness is the one with the lambda sensor - and is much easier to swap than the main one.

Don't bikes only go to Euro4? And Euro3 complicance seems enough to get around the ULEZ and hopefully other low emission zones when other cities follow suit.

I'll be amazed if you get anywhere near though, they burn too much oil for a start and cylinder head design seems to be a large part of bringing the emissions down to legal limits.

TFL state that all bikes entering the ULEZ in London need to be Euro 3 compliant, not 6 .. my mistake

ie manufactured after 2007 .

We can assume most uk  and European cities will follow with  clean air rules at some point in the near future.

The time has come  for me to find a newer bike to travel around Europe on, or just avoid  the clean air zones.

Will I keep my K100 ?  Definately,   I have invested a lot of time and money in her. to let her go.

The newer bike will only be for summer and trips abroad.

Just to finish of the thread

Motronic 2.1 and 2.2 ignition looms have an extra connector I assume this is for the Lambda sensor.

Pictured is a 2.2 loom, I have a 2.1 loom with the same connector. So to convert you need an exhaust with Lambda sensor. correct ignition loom and correct Motronic.

There is a shop that does emissions testing for motorcycles, it is near the Olympic stadium, they charge £150 for the rest, if your bike passes, they inform TFL and you get an exemption from the charge.
