Just got my 1200GS last monday - 2006 5300 miles from BMW.

Today, it feels just a bit lethargic, not as quick, rough idle, sounds a bit nastier on idle (i think) and does not want to take revs. Its ok if you apply revs gently but as soon as you wind on a bit of throttle, it stutters and holds back.

The bike is fitted with a full Akrapovic system and at the mo has baffle out.

The bike is running on 95 ron shell premium unleaded.

Seems to like a fair bit of petrol at the mo.

What do you reckon?

Also..........dunno if you guys can help here but -

I reckon the fuel gauge is either faulty or stupid! Full for ages, then almost empty and then light

Seems to be a graunchy / grindy feeling esp. over roads that arn't so smooth from the rear end of the bike through the footpegs. Its the footpegs that transmit this though because if i put legs forward when in motion onto the heads the feeling dissapears.

Rear suspension seems to be awfull soft with alot of bottoming-out? The adjuster is set to the firm side of normal but still?

Any help would be appreciated.

Thanks, Dave:beerjug:

Dave, am no expert mechanically but this has all the symptoms of a coil breaking down. Worth checking.


Nil Desperandum :eek: Someone will be along to advise on other symptoms soon. :thumb
 
5,300 miles ................. why don't you just get it serviced? 6,000 miles is just about due.

It does sound exactly like it's running on one cylinder.
 
Check RHS throttle cable where it goes in to the cylinder. If it is not seated properly bike runs rough.
 
Jack up the damping on the rear shock, it will sort the soggy rear.

Turraloon,

As you've just got it from BMW and its an 06 (same as mine) firstly take it back, I'd guess it came with a warranty.

As for the Fuel Guage, they are crap, mines shows full till about 180km, then drops to 2 bars for the next 100km then reserve flashes at about 300-320 telling me I've got 70km left. But its about the same every time, not erratic, so can be relied upon, you just have to get use to it.

Enjoy they are great bikes.

Coz its just been serviced by BMW before i got it. It's definately not running on just one cylinder, but does feel like its running on 1 and a half!

It does have the bmw warranty/assistance so if i must, then thats what i'll use.

Does anybody have a 1200 GS with a full Akrapovic with the baffle out?

I never noticed anything wrong before i took the baffle out although i was just getting used to it and hadn't done that much mileage. But im assuming, that a full exhaust system approved by BMW for the 12 GS, wouldn't make a difference if the baffle was in or out, hence my reluctance to put it back in as it does have a fair rip to it.

:):beerjug:
 
I've hear a few folk comment on their bikes losing power and not running as well when they changed the exhausts.

Is this your first GS? They do take a wee while to get used to as they are nothing like and jap bike. Suspension and handling seem weird at first but soon enough they are like a well worn pair of baffies!! :)

Really, my experiance and tose of countless others is just the opposite :confused:

Removing the baffle will not make your GS run rough.

Sounds like a coil breaking down to me (or loose connection) - the engine is a twin spark and if one of the coils starts to go you will not loose a cylinder completley but it will run rough.

Re the suspension; wind the preload up to pretty much max and increase the compression damping between 1/8 and 1/4 of a turn. Also try decresing the front preload one notch from standard - you'll find the bike steers quicker and more accuratley and won't wallow quite as much. Learn to trust the handling (there's not as much feedback as a 'normal' bike) and you'll be gobsmacked at just what 1/4 tonne of motorbike is cappable of :thumb2

This is my first GS but by far my first bmw - had countless, R80RT's and R100RT's.

The bike runs rougher than it did when i got it im sure of that. I'll call the dealership and get their opinion on it too.

Re the exhaust, i too also thought it strange that a free flowing sports system should cause your bike to feel lethargic and certainly not cause the severe stuttering / cutting out that im experiencing.

The handling is fantastic even with a soggy rear :ymca and ive already ruined the side of my right boot:augie but for those undulations on the road where its bottoming out i'll defo try your suggestion so thanks alot and all the others that have so far replied.

BTW, is a coil packing up on the 1200 a common thing?
 
Had EXCATLY the same symptoms on my 04 1200 a few months back, it's a tired coil.
