Cough and splutter

[haydw]

2006 ADV, 78k miles.
Very occasionally when I go to overtake something or after bimbling through town and opening the throttle I get a slight misfire for about 3 seconds before all is fine again. What’s more annoying is I can’t replicate it.

Plenty of fuel, battery is OK and nothing wrong with TPS etc. Not sure if it’s a coil pack but with it being twin coil I would have thought the second coil would negate that.

What’s the first sign of FPC failing?

Feels like it’s running out of fuel but 3 seconds later it’s fine and won’t do anything for another few days / miles. It’s mildly annoying.

Thoughts?

Thread 'Engine splutters on hard acceleration'

Apr 13, 2022

New to the forum, be gentle! Searched the site for a similar issue but can’t find someone with all the same issues after all the troubleshooting I’ve done.

2006 R1200 GSA 30k miles (owned for 6 months), recently started having issues under hard acceleration. Past about half throttle, when the engine has warmed up, the engine experiences lose of power by ‘stuttering’. The engine will still accelerate but jutters and splutters as it goes!

Been troubleshooting for air, fuel and sparks. Installed K&N filter, replaced all 4 spark plugs, checked all 4 ignition coils create spark, checked each...

Coils or fuel pump seem likely.

does it have ASC (traction control) ? If so press and hold the info button to move it from "nanny/children's" mode to "grown up world" - you'll see an S (for Off Road mode in German - its the S of GS). Note it also tweaks the ABS settings (but mine seems to work normally either way) .

I usually always swap to grown up world at key on every ride. But in the middle of resetting adaptions with new CAT sensors so using both at present, and I've been realising why I don't use the stupid default key on setting - in these cold temp damp weather conditions I'm noticing it can even get in the way with as little as 1/3rd throttle

NOW We know you are absolutely FULL Of Bullshit!

GS is Geländestraße = Gelände Strasse !! Probably easiest translated as Terrain Road

We ALL know S as in Strasse is Street (road)!

The S "may" stand for Schnee or snow but I just put my feet down and feather the throttle on my old pre traction control bikes!

I agree with him. As Mrs Gumby shouted.

I take it you are accelerating briskly under load ?

"Usually" this is the Main coil starting to fail But I would be inclined to check the Lamda sensors and see if they are operating okay and not sending an incorrect fuelling status to the ECU

I had exactly the same experience as the OP spanking it round some twisties in Portugal last year, only happened the once for a few short minutes, never happened again. It was how you could imagine a fuel starvation.

in the manual its states the symbol of an arrow around the S = off-road mode

it might be in some silly German world that the arrow is trying to indicate it means the opposite of Road
the purpose of my post was to be informative re. the option to reduce traction intervention

as usual your post was only to be rude and argumentative - you ought to be banned if you can't be trained to behave less badly.

Actually You have posted incorrect and misleading information Many many times !!

If you had posted the picture from the manual instead of the usual "Making it Up as you go along!" you wold not have received the reply

I am sure you have cost people money on here with your so called advice quite a few times Hence I chose to call you out With the intention that you be damn sure of what you post is correct!

This may not be the case, but if the throttle is opened quickly when trying to accelerate hard ( full throttle ) in too high a gear the fuelling goes lean before going rich causing a stumble.
I took the fuelling graphs of this condition to a self proclaimed tuning expert for his opinion ,he thought it was the "sensors being too slow" !!!!!?? BS
I assume it is in the engine load calculations , and makes sure you are in the right gear.
If in the right gear to make rapid progress and this happens I would first suspect the main coils.
FPC`s normally fail and not partially.
If fuel pump they tend to gradually lose pressure over a short period of time , on a 2006 bike it should be 3.5 bar the bike will still run and get you home even at 1.5 bar ( just) don`t ask me how I know.

He says it's a 2006 adventure, if it's like mine then it has no traction control so your advice is bogus.
Probably a coil stick starting to fail.

I have just updated my spluttering thread and will report progress in a few days.

ummm...

cough and splutter at wot revs ? I get a high rev issue (>7k) if I open up my TC, I found lots of oil in the airbox that when removed it worked OK

till I next gave real exercise and back to square one - my older hex one will rev to the red all day long and has for 35k miles and never had the issue - I'd be happy it was just my TC is crap - except one bod agreed his TC did the same

I was thinking either
1) the engine breather is a joke on the later bike
2) it was owned by a girl that never got the rings to bed in for his 9k miles of use before a grown up got on the thing
3) but - re reading your thread gave me a new thought - does it need thin oil that flows back so the crank doesn't whip it all up and swamp the naff breather - and thus if you run 15w50 weight like the older tractor needs, does this later design whip it up and make a mess in the airbox for riders that use the high top end grunt these later ones were meant to have....

EDIT: Oh your first post you have a real one - not the TC
still point three might apply on TCs

So experience on my older hex... with cold weather rough running. Early ones went better - but ran rougher lower in the rev range. Mid 2008 the early bikes had a range of software mods available that most dealer's ensure they never apply. Three engine points where addressed plus trip computer bugs, side stand logic rethink and TPMS updates - I had the 2008 map flashed on the bike in 2018 - and ever since winter riding has been a hideous mess up. Never an issue in the 8 years prior - but post update winter has been chugging recalcitrant mess up. One of those engine points addressed in the later software was cold weather enrichment...

With the cold back and now using the bike daily - I can't stand the mess - I just bought a new ambient temp sensor (only 12 quid) and some Chinese NOx sensors at 13 quid each - the bike is now dead std with the PC3 out the way and immediately the new CAT sensors show the crazy adaptions waking up and controlling cold weather running much less badly - its still horrific but more rideable - the adaptions per cyl have leveled out - prior cyl one was crazy rich

but extremely light throttle the map is plain wrong - with no fuel to run properly around 2.2k rpm and again at 2.6 to 3.1k rpm - so long as you keep opening the throttle it rides much better and runs well. But idle is weird, its far more stable (without cyl one over fueling), but leave it idling at lights and the thing will go from normal, to chug almost stall, and back to normal 6 seconds later, in a fairly random roughly 90 second batch of confusion. Sometimes it never does it - another ride it will do it every other 10 seconds - the old map was perfect in winter
