Will you be fitting acetylene lamps, leather belt drive and a nice sharp pedestrian cutter front number plate while you are at it? Regardless of the legality, the MOT is just a scheme to sell non-strident horns and replacement light bulbs. They won't spot anything this technical and won't start the fight as the fix isn't just a case of selling you something. Faced with a fail you'd just find another MOT station although for such a big fail you may actually complain and highlight that they don't know the rules themsrlves. This may change, ending tests on 40 year old machines they don't understand is the start of the clear up, but it will take years before they stop trying to test a computer with a slide hammer. What I don't get is why you would remove a working system with built in blink code diagnostics and fit a tin can full of swelling bits of rubber that is set up using naked dancing in the forest at the full moon and rituals involving dead chickens? The FI is more efficient, more reliable, less polluting. Leave it alone IMHO.

I suspect the first time someone who thinks rules and regulations don't a apply to wise men take what should be Euro 4 compliant motorcycle, for its first MOT will be in for a shock.
The emissions testing kit computer will have like car MOT emissions tests a direct link to the government vehicle data base.
Any modifications will make a bike not possible to sell and also nullify the insurance.

I suspect most of this is done with the sole intention to lose weight off of the motorcycle to improve its acceleration. < br> Anything short of the rider going on a diet seems to be fair game these days in an attempt to get to the pie shop a little bit quicker. Certainly something I’ve been guilty of in the past.

Personally I shall probably stick with pre Euro IV bikes. At l ast they do not have to meet current regs (yet). The single best mod I have done to my C5 is the carb replacement. Maybe I was unlucky but I had a few issues with the EFI on mine, mostly down to sensors and connectors. I am no Luddite; EFI has advantages several advantages and, actually, my C5 is my first non-classic bike to have a carb in nearly 20 years. I have to say, though, that I usually want to adjust the fuelling for different exhausts, air filters etc and in this respect the Keihin system fitted to the RE is pants. AFAIK you can’t reflash the ECU like I have with my Triumph (and remapping that to suit aftermarket exhausts and air intake, removal of secondary air injection junk etc has completely transformed it). You therefore have a choice - spend loads on a PCV and map or bung a carb on. I chose the latter. It now ticks over reliably hot or cold, sounds better with an air intake where it should be, looks better and more like a classic and needs a little ritual (tickling the carb) to start ( which it does first time). No
MIL to worry about either ( in fact I shall probably replace the MIL with an ammeter- I lose the low fuel warning light but I have a reserve position). The only slight concern is ethanol, but that can be dealt with. Ultimately there is nothing that I have done that cannot be reversed (I’m hanging on to the EFI bits for that reason). Basically I like modifying my bikes; the options with a IV one may be more limited, they certainly will be with Euro V.

Yes, pre EuroIV definitely seems the safe way forward for anyone wanting to a run a modified motorcycle.

I read somewhere that some EU bright spark wanted to harmonise motorcycle and motorvehicle Gaseous pollutant levels.
The bike ones are to be advanced to catch up with the EuroVI regs imposed on cars. Although it didn't make any mention of motorcycle emission testing as part of any future motorcycle MOT its not a giant leap to think it could be included at some point. New bikes over 125 ccc already have their emission data printed in the V5c, my 2015 Enfield certainly has.
It's therefore not too giant a leap to think some retrospective legislature could also be thrown our way in a few years time for those (EuroIV) bikes originally manufactured with a catalytic device within the exhaust system.
Just hold onto those OEM silencers and Evap canisters...

[stinkwheel]

Yes. I read both articles article on euro regs thoroughly. Setting aside why you may or may not want to, I see nothing in them suggesting tampering with your emissions control equipment would render your bike unroadworthy or in any way illegal. These regulations apply to manufacturers of NEW bikes. As in, when you design and sell a brand new bike into the UK market, it must be type approved as being compliant with the relevant emissions regs. What happens to it after that is up to the owner.



Part of the EURO 4 regulations are that they have to show that that engine DESIGN, as it came off the line, will still be compliant after several years. They are not actually testing peoples bikes for emissions, nor am I aware of there being any intention to.



For a third time I reiterate that I am aware of NO REGULATION AT ALL which allows for emissions testing of a privately owned motorcycle in the UK, nor am I aware of one which prevents the owner of said motorcycle tampering/tuning or in other ways mucking about with their bike. Motorcycle MOT stations are not equipped to test emissions anyway, nor are they equipped to read ECU codes. Given there are still some which use spring or sliding floor brake testers, I suspect there are bigger fish to fry. My local guy was hacked off when he was made to get a computer in to do MOTs.



There is a part of the EURO 4 regulations which puts an onus on the manufacturer to make it diffcult, by design, for the owner to tamper with the power train but they are regs for manufacturers, not owners. If I'm prepared to drill out antitamper fittings, re-flash the ECU and fit a sensor bypass device in order to fit a de-cat pipe to my sportsbike, that's still my business.



In fact, If I were to build a one-off, brand new bike from the ground up, I could register it for road use under MSVA rules and nobody would test it for C02 or evaporative loss emissions at all. They only check carbon monoxide emissions are less than 4.5% and that it doesn't pump out visible smoke for more than 5 seconds at a time when returning to idle. Frankly, even with a performance 2-stroke, you'd be wanting to sort it out if it was that bad.

[papasmurf]

Stinkwheel if you buy a NEW motorcycle, that HAS to be Euro 4 emissions compliant, it will have to STAY compliant.
So any modification that make is non emissions compliant will mean it is not road legal.
This will be tested at MOTs and also roadside checks.
The local motorcycle mechanic is grumbling because of the expensive kit he will have to buy to make sure bikes that were delivered as Euro 4 compliant are compliant at MOT.
Is that clear now.

I’m with Stinkwheel on this one. I have found nothing to suggest that bikes are to be subjected to emissions testing. My reading of Euro IV is that the manufacturer has to provide the technology to enable it to be demonstrated that the fuelling and ignition system has the means of showing when they fall out of the specified parameters ie they have onboard diagnostics and an engine warning light. That is not the same thing as saying that emission testing will be introduced or outlawing owner modifications per se. (Remember the outcry when the Germans wanted standardised MOT testing and to ban ALL non type approved mods?). This is no different to fitting a pair of megaphone silencers on a Bonnie back in the sixties. If anyone can point to an accredited source explicitly stating that emissions testing will apply to bikes then I’ll be persuaded otherwise.
