Interesting. I doubt that the anti-roll sensor has anything to do with the ABS system. The one on the RE is basic by modern standards and doesn’t work while cornering. The higher-end bikes that have cornering ABS use an IMU (inertia measurement unit) which basically tells the ABS control unit the angle at which the bike is sitting. I believe the sensor you are referring to is probably the one that cuts the ignition if the angle of the bike is more than a pre-determined limit. It is a safety feature to stop the engine revving itself into oblivion should the rider crash and the throttle stick open. This isn’t unique to the Euro IV bikes; my 2015 has one. And, yes, they have been known to cause issues so it could be that. I had thought (hoped) that the better QA of the Euro IV bikes had put to rest the gremlins caused by el cheapo relays and fuses and their connections. Oh well. I’m sure we’d all love to know what the problem turns out to be.

Since the MIL light went out when I lowered the sidestand, I have ridden about 50 miles without further problems. With the ignition on, you can hear the two relays in the LH tool box operate as you raise and lower the sidestand. I have not lowered the sidestand with the engine running since or started it with the stand down. I still think that starting with the stand down confused the ECU somehow and it took a few starts for this to clear. Of course,I also checked all the sensor connections too but it is odd that the misfiring started when I did something I had never done before -start on sidestand.

Just as a preventative measure, it's best to adjust the side stand switch so it cant engage/disengage until it's traveled at least half way through its arc of movement.

I have a Euro 4 C% from the same dealer. Hosts exhaust system which retains the O2 sensor, and K&N filter, plus the Air injection elimination kit. Running fine then like yours, last Wed stuttering and dying at low throttle from the off - I revved it and it popped and misfired. Persevered and it ran fine after about 5 minutes and then onto the motorway. Started it yesterday, seemed OK - and I narrowed the spark plug gap which looked far too wide. Arrived at pal's house, and then same stuttering began, and surging, happened twice more AFTER stopping and on to side stand. I was thinking of the performance kit and power commander to get things set up properly as I thought it was a fuelling issue. Can you explain what to do to 'clear' the sidestand issue, if that was the problem?

After a few days of misfiring and after checking sensor connections, the MIL light was still on. I then started the engine with the sidestand down (which is what I had done when the MIL light first came on) and the light went out and I have had a few runs since without misfiring. I have avoided starting or running the engine with the stand down. Of course, it could be just coincidence and the MIL light may just have cleared itself anyway. But it was odd that the problem started when I started the engine with the stand down - a thing I had never done before.

My 2018 Euro IV C5 has what appears to be a PAV (pulse air valve) on the front of the cylinder. i understand this is supposed to re-direct unburnt/partially burnt fuel back to the intake and operates at speed and not when idling. I'm suspicious of add ons like this as it reminds me of the 70's when cars were coming out with environmental stuff bolted on resulting in sub par performance. When my bike was playing up I wondered if this could have had something to do with it but the dealer and importer were not familiar with it. I also understand some Electras had a similar item and that it was possible to remove and blank off the port.

Your "pav" feeds air into the exhaust port to help burn any unburned mixture that might be there to help clean up the emissions.
It's not an EGR valve which is used on some cars to recirculate a small portion of exhaust gases back to the intake manifold. Yes, your pav can be removed.

While the bike is at a standstill - different to previous models - it will start with the sidestand down, it will only cut out if you try and pull away.

It seems to be similar to the SAI system on the air/oil cooled Triumph twins now superseded by the l/c ones. A lot of owners, including me, disable or remove it with no ill effect. If I had a Euro IV C5 that’s what I’d do.
