Good to know Wayne I wonder how many other people have been needlessly twisting the throttle. Also how many other urban myths there are out there

Reset TBPS by turning on ignition and turning twist grip to 100% and back 3 times then turning off the ignition for 10 seconds
This has a varying amount of success

This process is an urban myth which people apply to a few models, it was only applicable to some early 90's models

Thought I would let the forum know how I got on as there's been aa few viewings but no replies it's obviously not a common fault.
For a start I need to thank Ted at Motorevive he's based on the Wirral and gave me solid advice.
This fault was driving me up the wall but I have managed to fix it now fingers crossed.
The issue all along was the Throttle body position sensor was not showing 0% when the throttle was closed. On desperation I decided to reset the adoption values again on last time and it made the problem worse. Before the reset the closed value was 5% after the reset it jumped to 25% and the bike was running worse than ever.
I figured the adaptation reset was having some effect on the closed value so I reset the adaptation values again. This reduced the closed value to 20%. As it was heading in the right direction I tried it once more and it worked. Now the closed position is 0% at all temperatures and the tickover is perfect.
I have got to assume there's some sort of bug in the system as this shouldn't be a hit or miss process.  Hope this helps someone somewhere

removed rear wheel, used GS911 and sensor wake up/learn tool so bike knows new sensor, had old sensor removed and installed new sensor. now at aprox 20 mph both front and rear sensors wake at the same time and bike displays correct tire pressures   joy again

On the bagger, even though the physical switch and wiring harness are there, the bike’s ECU/TFT doesn’t “know” it should monitor that circuit and display the icon.

Hello All any help appreciated
My issue is as follows. Bike was running very rough on tick over and up to 3000 rpm
I have found the following faulty parts
Lower Right ignition coil (replaced with new)
Fuel pump regulator (Replaced with new)
TBPS first cleaned then replaced with new.
The only issue I have now is a higher than normal Tick over 1500 rpm
I have tried the following
Reset adaptation values
Reset TBPS by turning on ignition and turning twist grip to 100% and back 3 times then turning off the ignition for 10 seconds
This has a varying amount of success  .
Sometimes the closed throttle TPS is 3.4% sometimes it is 0% after reset procedure.
Even when I manage to get the closed position to 0% if I leave the bike ticking over the closed value slowly increases from 0 to 0.39 to 0.78. to  1.17
This takes the bike out of "idle speed control" and the tick over slowly increases.
I have measured the voltage on the centre pin of the TBS and it remains constant despite the value on the GS 911 increasing
I have also measured the resistance of the cables from the TBS to the ECU edge connector and they all test out OK
The firmware in the ECU is K024-10-02-550
I have read that a firmware update can fix tick over problems.
What is the latest firmware level for the K25 ?
Is this something that a Motorrad dealer will do for free in the UK?
Am I missing something simple out here?
Thank You in advance Col

Yea   I probably did, and after trying to write down code I did a reset I will need to wait and see if code reappears.
problem I have is tire pressures take a very long time to be displayed. rear a lot longer than the front. I am guessing front and rear sensors need replacing.

they do - they have to wake up, can take up to 3 miles often gets worse as the batteries get low...   sometimes they'll be there inside 1/2 mile often takes more
