loud audible "CLICK" before revs ramp up.

Could be the stepper motor which controls the throttle butterfly valve.

 

Forchetto, you were very close. My bike needed the throttle bodies adjusted. They were out of sync and that caused the problem. Once that was done, the clicking or popping sound went away, and so did the occasional stalling.

 

I have only noticed the click occasionally when I blip the throttle while downshifting. I was accidentally in Road mode at the time. I have also had the stalling issue twice. Both were during braking and downshifting from third to second to accelerate. When clutch was pulled in fully she died. Both times were in traffic and I just hit the starter and was on my way. Both occurrences happened in Sport mode and both times I forgot to switch back to Sport right away.

I have heard the loud click once and was like "oh that is what they are talking about".
Haven't had the stall issue, but I have stayed out of sport mode till I pass my 500 miles.
If I recall there was one journalist who had the issue at the launch event also. Forgot who it was, but when the guy brought it to the attention of the engineer he knew right away about the issue. We shall see if it is an easy fix or not.

 

540 miles - not heard it

I'm at 540 miles and have not heard the click. The bike did stall twice though. While in SPORT, when coming to a stop.

 

I have been in sport and road modes and it has clicked in both. Both when idling in neutral and blip throttle. Most recently did it 3 times in a mostly highway 150km stretch a couple days ago. I have never stalled however. My service manager thinks it is stepper motor and also expects Triumph to release corrective tunes.

 

Just to add, I was in road mode and it happened while downshifting as well. Clutch in, changed gears, gave a bit of gas, and it died. Stalling only happened once, but I heard the clicking two or three times.

 

Mine finally stalled yesterday while releasing clutch after a downshift when make a right hand tight turn at an intersection, good thing no one was behind me as it took a couple seconds to restart again.
I am pretty sure a brand new $18000 bike shouldn't stall under normal operation.

 

I seem to be having a different problem. Mine has died a few time when I pull the clutch handle in after engine braking down the hill into my neighborhood, like the revs just bottom out. No click or anything. Only has happened in this situation and intermittently.

 

I agree, it is not holding the low revs when they start dropping. The clicking I hear is almost like a starter stopping click, hard to say.

 

Only when hot and idling at stop

I have a 2016 Thruxton R with the same problem. My bike has stalled on take off and on downshift to first gear at low revs. There seems to be a clicking sound first, then a pop, and then the engine cuts out. This only happens at around 1300-1400 RPM. The bike has to be hot (ridden for over half an hour) and I am usually sitting at a stop light, or inching through rush hour traffic.

I read some of the other forums and this seems to be a common issue with many of the Triumph models. I called the dealer and will be bringing the bike in for service. This needs to be fixed. It's dangerous and nerve racking to have your bike cut out in the middle of a turn.

 

Haven't had any issues with stalling in past 300 miles. Hopefully the ecu sorted itself out. Changing oil this weekend and hoping the stalling doesn't return. Wasn't a big issue when it did happen but it shouldn't happen anyhow.

Went for first service and they did a reset adaptation. bike runs much better now with none of my previous issues, only a new issue of taking 5 sec or so to fire up when holding the starter when the engine is cold

 

Interesting. Probably not this but some of our cars cranked that long before fuel was delivered, possibly to build up oil pressure before firing.

 

Problems continue

At 250 miles I brought it in to the dealer and they re-set the adaption. But, it's still stalling when the engine is very hot and I'm in rush hour traffic. Both coming to a stop and pulling away from a light. Seems like it happens around 1200 RPM. The bike is in for its 500 mile service now. The dealer is also adjusting the throttle bodies per advice from Triumph technical support. I should be getting the bike back today and will report whether is issue is resolved.

 

Thanks for the feedback. Strangely the dealer is meant to check things like that during pre-delivery. See it on this excellent video of a T120 being unpacked, prepared and test ridden. At minute 5:15 when they plug it to their PC one of the things they're supposed to do is check synchronisation of throttle bodies:

My Thruxton R has stalled on my twice so far (130 miles on the clock), both times were from opening the throttle quickly from idle. Hopefully it will be sorted out at the 500mile service. Harder acceleration has slight juddery feel to it right now which would suggest to my the throttle bodies are not balanced properly. It's still running in so I expect a certain amount of quirkiness.

 

I wonder if the 12 minute adaptation (or 12 minute tune) applies to these bikes as with other Triumph models? If so, I'd be doing one of those ASAP.

I do recall that when my Speedie was brand new (going back to late 2014) the throttle bodies were way out and it needed to be remapped. That was at 1000km. Not cool.

 

question

Hi all,

just received my new Thruxton and I have this problem as well (exactly as depicxted on this thread).
i have a few questions though:

- do you think that the whole power curve is affected because I have the vague feeling that it is not as powerful as it should be?

- when accelerating (being in 3rd at 2500-3000 rpm), I hear a not so cool noise that comes in addition to the roaring twin, (difficult to describe), has anyone noticed something like that? can this be related to the same problem?

-what can I tell my dealer in order to make sure he will be able to fix the problem? has the issue been clearly identified? He's surprised i'm the only of his customers who mentioned this.

thanks for your answers, it's good to be back on the forum!

 

We have seen this in our neck of the woods. We adjust the steppers at the 500 mile service and it goes away. I just read a previous thread about doing your own 500 mile service. While many things can be done by the owner, steppers can not "unless you own a Triumph store." Please have the steppers done and a GREEN SHEET printed up. All the new Street Twin, T120's, and new Thruxtons get progressively worse unless this is done. Paying someone to just turn the wrench off should be a red flag. I turn that down at my shop. Honesty before profit. I hope it pays off.

 

Dave, when you say you adjust the steppers, is it a physical intervention on the bike,or is it just done by plugging it on the computer. The mechanic said all is done via the computer

thanks for your answer, sorry to ask but what's the green sheet about? It looks like this is something that all triumph dealer are aware of, how come mine seems to be so puzzled by it?

 

what's the green sheet about?

Probably the doc shown on post 38 of this thread:

GREEN SHEET

I apologize to those if I didn't clarify. Green sheet is my own name for the attached doc. It verify's that the work you paid for has been done. The VIN must match of course.

 

So, just had the first service done. I provided them with all the info that I could find here. They uploaded the new curve. Initially the computer said the throttle handle was not adapted (no green). They changed the throttle sensor and it sorted it out. They said the bike was ok. Indeed, it runs much smoother in the low rev but it didn't solve the engine cutting off issue. Don't really know what to think about it. It's not only a comfort issue but also a safety issue, I don't want to find myself in an emergency braking with a dead engine, loosing the abs and all. Don't really know what to do now. I'm not going to go back to the shop every week until the find out. Anyone has an advice?

Had my 500 mile service done yesterday. I don't think they updated the tune, but I probably had the latest when I picked up the bike 3 weeks ago. I didn't really have any idle issues. The bike did have a bit of a 'sputter' while rev'ing that I attributed to the 270 firing order (this being my first big twin). They did say the throttle bodies were pretty far out of sync. The bike does seem to rev much smoother now, and just in the 150mi or so that I put on the bike since picking it up yesterday, I think my MPG is up a bit (will need to confirm after my next fill-up).

 

My Thruxton R has been stalling on the down shifting since day one, I took it for the first service and got the green sheet, they reflashed the ecu etc. it was ok for awhile but won't start on first push now, I now have 5000kms on it and it's started the stalling again. Dealer says no updates yet. Triumph needs to get this problem sorted before someone gets hurt...

 

I had a PC5 installed and an auto tune module. Problem was solved and made riding my R much more enjoyable. I highly recommend it. Bite the bullet

 

HI everyone,

I'm fairly new to this model Thruxton R and of course I have encountered the clicking issue few time while opening the throttle. I will take my bike the first 500 mile check soon but dont really know what to describe the issue. Hope they can fix it in Thailand or beware of the issue.

Now, I'm starting to modify my bike. Thinking of put of aftermarket Air filter like the previous model (BC air filter), the conical one and get a hand made full titanium exhaust with power-commander to adjust the map and ECU


And I would put a set of forge wheel from DYmag.


What do you guys think of this of approach?
Is there any concerns for doing this on a very new Thruxton R?

The dealers have access to a new map that takes care of the issue you talk about - when you take your bike in for that 1st service, make sure to ask for a print-out so you can see there was an updated map applied.

I'll let those with direct experiece answer your other questions - welcome to the Club Cafe !

 

What new map.....?:smile2:

I don't think there will be any new maps coming from Triumph, PC haven't got their systems running on any water cooled models yet and they don't have any maps either.

But that was last week.
