i have a euro4 bike and i've now had my 2021 gt650 stall a couple of times going off the line at stop lights. today the light turns green, i give some throttle and ease off the clutch as per usual. bike just dies. i've had this happen maybe 3 times total on this bike with about 2500km. which isnt terrible. but thats about 3 times more than its ever happened on my other bike with nearly 20,000km. i've never stalled just trying to get going and its embarrassing since cars are behind me.

i also cant tell from the analog dial, but it seems my bike has been idling closer to 1000rpm than 1200rpm. it kinda dances a bit. the temp here in canada is definitely getting colder recently (been riding in 0-10C or 32F-50F) so i dont know if that has anything to do with anything.

i did replace the exhausts with a pair of scorpions, but this also happened when i had stock exhaust still on there.

does this have something to do with the ecu and 'quickly switching from idle circuit to its low-speed circuit, and back again'? each time i have no idea if its 'dipping below to 800rpm' or anything since i'm not looking at the tach while riding.

Hi All, did anybody solve this issue? I’m facing the same situation with an almost brand new interceptor and it’s quite annoying.

Mine did exactly the same thing from new. Went back twice to the dealer who replaced the ecu. Completely different bike now with no issues. Good luck.

Hi guys

Same issue with my new 2021 EU5 Continental GT 650... it did it in the very same day I went to the dealer to pick it up! I tought it should be down to the bike being in the break-in period, but with all these comments here in the forum, I guess it´s not.

Still with only 200km (124 miles for you UK folks out there  ;)) it has happened 2 more times, always under the same circunstances. Small blips in the throttle at low revs, the rpm drops to 800 and if the blip occurs when the rpm is in that low range and it stalls. It always happens during very low speed manouvers, like in heavy traffic when you are squeezing through cars. It makes sense, because that´s when you´re giving small throttle inputs.

It seems it has to do with fuel managment by the ecu and not with any faulty sensor.

I guess I will wait for the post break-in first service at 500km (310 miles) to inquiry the dealer if they are aware of this issue and if there are more complaints from other owners or even a service bulletin issued by Royal Enfield regarding this issue.

I´ll be following this post and reply when the time comes.

I had the same issue on my 2021 euro 5 spec conti GT....especially on the way home after picking it up new from the dealer, happened a few times on the 25 mile journey home. It did get better after about 400 - 500 miles (650 - 800km) but I did find that on the end of the throttle cables, under the side cover to the throttle body, that the tiny rubber end caps had come off the adjusters and got stuck in the groove of the throttle body cam and was effectively changing the position of the throttle...I fitted them baack onto the ends of the cable adjusters and also adjusted the cables as they had way to much play and that improved it a lot, never stalled since...... might not be the issue but thought I would put my experience out there.

When using E10 fuel my bike does not tickover as smoothly as when running on E5.

Still young enough not to care, too old to remember why.

You mean like this? I posted this a while back. Mine was the same.

Well, doesn´t hurt to check it out! Thank you guys for sharing feedback and also for the picture... it helps a lot in knowing what to look for  ;)

As for the type of fuel I´m using, it´s premium E10... that´s what the dealer recomended.

This sounds like a similar issue the early GT 535's had. Yes, different motor but very similar issue. I cured it on my 535 by installing a PC 5. Not suggesting at all that is what you need to do though.
I agree with others that have said take it to a different dealer for diagnostics.  Good luck!

I´ve checked my throttle cable and sure enough, it had the rubber nipple out of place and jammed.  :o Dispite that, it didn´t seem to affect the normal functioning of the accelerator. I´ve put it into place, but the problem still persists. Still stalls when minimal throttle inputs are given.

As for the Power Comander V sugestion (or any other piggyback solutions) sadly being an Euro5 model (2021), means that those devices are not compatible, since the ECU´s are built with extra security measures that monitor and detect suspicious sensor reading values, wich would trigger fault codes and impair the normal functioning of the bike. At least, that´s what I read somewhere... .

Oh well, it´s not a big deal, I still enjoy riding it and I can get around this issue with a slight change in my riding style. I´m still going to bring this matter up to the dealer when the time comes for the 1st service.

honestly that sounds like a pretty big deal to me and super annoying. its a brand new bike. having it randomly stall on low revs is unacceptable, nor should a PC be the solution.

Thinking of buying from Alcoa Good Times in Tennessee? Don't! Message me and I'll tell you why.

I’ve just had the same problem with my new Interceptor, 140 miles.
I checked the pipe connections to the throttle body and the cable connections to the throttle position sensor- all seemingly OK, but then found that the throttle body butterfly stop adjuster (located on the bottom of right hand throttle body) had not been screwed in enough to contact the throttle cable pulley, thus allowing the butterflies to bottom out on the Venturi. A small increase in the idle speed by tightening this a little has much improved the problem. I think that with Euro 5 specs a warm engine is always going to be touchy at low revs with such a weak mixture. I noticed the problem didn’t occur when the engine was cold and automatically enriched by the ECU. Good luck!

I got bike back from dealer, they did some "adjust" to ecu....problem still persists. I couldnt talk personally to the mechanic...i talked to some helper who didnt even look me in eyes....i didn´t like him.

Bike is going dealer again....it stalls on decelaration when i press clutch... on idle once...

But worse is that theres a new problem ! Now gear box gets stuck sometimes. I find myself stuck on neutral and i cant shift to first...when eventually do i do, engine shuts off....or will outright not let me start on first, just neutral, eventually after 4 embarrasing minutes stopped by the road, the bike lets me go when it wants too.

I dont know how im gonna work tomorrow. Unbelievable.

Im not sure if im just unlucky....or if the quality control of these machines are just this bad.
