2011 R1200GSA struggling to accelerate at high rpm problem!!
- Thread starter Moonmanzn
- Start date
Nope, made no difference
Still have the slow drag feeling from 80 onwards
Well time to take the exhaust off and try that.
Maybe it doesnt like decatted headers and no backpressure

is that white or alloy???
You would not be getting 240PSI with dodgy sealing valves so at least thats a bonus

One more question if you were to sit down and go through in your head when is the First time you noticed this
what was the last thing you had done to the bike prior to that

Dr, it's just clean alloy. Wiped the soot and it's not deep.
Just a coating.
Problem is I drove it home after purchasing and as it's been stood 12 months I didnt hammer it so didnt notice any issues.
Got home and major serviced it, new full exhaust and rapid bike evo.
After that it bucked hard on a ride and noticed some days it felt fine and some days felt held back.
I'm now at the stage that it always accelerates slowly past 80.
I have stock exhaust and flapper back on so will take a ride now.
What I need to do is ride another TC 1200 and see if they all feel like that.

Water Droplets or other Crud lodged somewhere in the Fuel System??

Knock sensors are just for picking up a certain vibration and sending a signal to ECU, they are piezo-electic things. There is a remote possibility this could reduce the power / retard the ignition in your case. I would just disconnect them electrically and see if it made any difference. Take a minute and cost nothing.
Sooooo
Exhaust doesnt feel any different.
However I have noticed if I'm at 80mph...and take throttle to say 90% throttle it will speed up with a surge like I'm expecting...so tried that a few times and could get it to feel good if I almost part throttled up.
Then I took an off ramp and went around a round about back onto motorway and then it wasnt happy at all and had the massive half back feeling again.
I have swapped the TPS off a F800GS which has same part number so that cant be it.
If I check TPS in GS911 it goes from 0 to 97.86 ish WOT.
Almost feels like sticky actuators or something throttle wise but not TPS

The fuel system should be clean as checked filter and its spotless?
But possibly the turning right around round a bout sloshed the fuel? But I taken some quick turns on way to M3?
Knock sensors are my next attempt

TPS should read from 0 to 100.01
On your earlier .CSV data file your knock sensors looked OK.
Have you any data on this recent ride.
It will take a few tanks of fuel for the long term fuel trims to establish now that you have made these changes, especially working lambda sensors ?

No data as laptop setup at work.
Fetching it tmrw.
Will jiggle TPS and see if its slightly out.
Compression seems high at 240 psi?
Also my coils seems to have pushed out a good cm or so. I'm wondering if they are not torqued down enough and loosing compression at high rpm?
Getting an adapter for my torque wrench tmrw to get down the plug hole and nip it up and then try again.
I opened up throttle bodies and they are spotless.

Have you left the terminal nuts on the spark plugs?

Compression pressure sounds high to me, not sure what it says in the manual.
I normally work on compression ratio X 1 atmosphere. So 12 bar or 175 psi, ?
Don`t forget they are the little plugs in the TC so check the torque settings.

you can clean the TPS yourself if your carefull
there is a repair / clean pdf floating around somehere
If the tracks are too worn then cleaning wont work
a non oem replacement is usually available on the bay for about £40
I think ive got an old or cleaned one somewhere

Yeah, all plugs disconnected. One out and gauge in...wot and chug till it stops moving.Compression pressure sounds high to me, not sure what it says in the manual.

240psi both cylinders
