Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Technical inspection of three-wheelers in France

the technical inspection for three-wheelers and motorcycles has been mandatory for about four months in France. I managed to get it thanks to the goodwill of the inspector because the CO level was not good despite having put back the original exhausts with the catalysts in perfect condition, it could not reach the right CO level for the euro 3 standard. I think the cause is the 569 camshafts. The inspector told me not to put back the entire original exhaust system for the next inspection for the CO and the noise in complacency with the three-wheeler. Moreover, it did not even get into the TW. He just asked me for the lighting and to accelerate to 2500 rpm for the CO. So my question is whether others have passed the technical inspection with 569 camshafts.
So at the next technical inspection I'll go with the 132 cub transsexual engine with 618 camshafts.

In the UK Three Wheelers do not have to have the MOT emissions test. Which is a good thing because the M3W is vey marginal and likely to fail even as stock. Tuned with 569 cams it will be fairly well out of range.

Bad idea
I boycott mot

Unfortunately it's a legal check to be done every year once the car is 3 years old.

Hi, this is my first post!
I passed the technical inspection in France at the end of April. My tricycle passed first time, the CO2 level was good. It's a 2016 with a stage2 upgrade from Garage 56.

Do you really have 569 camshafts? and have you really seen the CO values ​​on the control device.
My 121cub is modified at the volumetric ratio which must be about 10.8 instead of 9.75 as well as the combustion chamber a little modified with original exhaust it is imperative to have octane booster to drive on the circuit so as not to damage the top engine.

Oui, j'ai les AC 569. Je te communique demain la valeur en CO2, c'est écrit sur le rapport de contrôle.

569 cams are fine with the standard compression but do need a modified ecu map either from an unlocked Morgan ECU or a replacement such as Emerald.

The technical inspection report states that the CO content is 0.05%. The maximum acceptable level is 4.5%.

Germany here: we have to do the HU (Haupt Untersuchung, the german MOT) every 2 years.
The m3w is classified as vehicle class L5e (that means a vehicle with 3 wheels and quicker than 45 km/h);
in march 2024, the CO Value was (engine warm and turning 2.000 RpM, allowed between 2.000 and 3.000 RpM) 0.14 [Vol.-%], allowed is max. 0.3, so the "car" passed the test.
