Hiya bud

that picture is part of your diagnostics circuit,  You connect that and turn ignition on (but engine off) to check throttle body sensor position (it'll register a "0" or a "1").  ")" signifies correct TBS position ans "1" means it needs a tiny tweak one way or tuther (the throttle body sensor is housed on the TB and has a locking bolt that if slackened slightly allows setting of sensor).

Cut wire by battery could be from a former alarm or something?

if you check the block connectors to your ECU box, the one on the far left lower corner should be a blue/green one.  That's your Map1 or Map2 wire.  Connected with the RP58 chip in place (if still used on the 53 reg bikes) it runs on the restricted map.  Cut, it runs on the full power map, or more accurately, one runs leaner for Euro compliance whilst one runs richer at higher revs and allows allow open pipe/fast flow air filter.  If it runs rich, get the tuning checked out by the Griff Meister ;-)

No, no major issue, just a minor adjustment.

Locate the throttle body sensor.   remove left hand fairing panel and look to the rear of your throttle body stack for a black plastic or alloy casing with a sensor wire connected.  You'll see that the sensor body is retained by a single pinch bolt.  Slacken this slightly and turn fractionally one way and the other way whilst reading the sensor position off the dash.  When it reads zero, that's where it should be.

All this does is tell the ecu where the throttle closed position should be for correct fuelling.  Get it out and it makes a difference to correct pick up but not the end of the world.

That picture shows multiple wires and it looks more like a power circuit than a control circuit.  My best guess is that it is from an old alarm unless it is clearly wired into the main loom, but if it was, I'm sure you would have picked up by now that something major wasn't working!

Hi
 
You cant read the Diag reading that way its not accurate!
 
It will read 1 because the fast idle screw has to be wound in to bring the idle up to the correct level
This reading is for checking the TPS sensor and it should be read when the fast idle screw is wound completly out.
 
This is just to ensure the TPS is set to 0
If your bike is running ok leave it well alone.

Yup, well picked up and my apologies as Ed's right of course.  Idle screw all the way out. No biggie to do though and no harm in checking.

'Right' is a relative term where Italian electrics are concerned - might be that Luigi at the factory was gagging to get home for his Carbonara so just snipped and taped to get it off the production line!
(Although probably not).
