Help with identification of a - well I do not know what it is...

So the pics above are from my 2013 1200GSA, last of the oil heads, I believe. I do not know what the cable in the picture above is, or where it connects, too, even if it should connect to something. It seems to go under a fairing piece below the seat, but I am still none the wiser.

I came home from a ride yesterday and it was just there, hanging out the front not doing anything. Not anywhere near the wheel, but a bit too close to the engine for my liking, not to be doing something. The kind of copper (?) metal piece at the end seems to be blocked up - should it be?
Should it go into some thing to make a connection?

Any helpful, knowledgable, appropriate suggestions would be much appreciated. thanks guys, and girls, if any of you have a clue that's cool too.
 
it looks a lot like the ambient temp sensor for the joke that is the pointless booster plug ?

its meant to be an improvement to the early design of fake cold weather to enrichen the fuel mixture - It goes on the AIT (Air Intake Temp sensor) and with a new ambient sensor away from the engine heat allegedly works better - except within 15 miles the engine adaptions will have zero'd out the slight enrichment it had brought as there is nothing about these that can work

sure the bikes fueling desperately needs help especially as running E10 Ethanol fuel weakens the already too lean BMW map by a further 4% but those aren't the way to do it

Impact of Ethanol on Air-Fuel Ratio (AFR)

Ethanol Blends and Stoichiometric Ratios
Ethanol affects the air-fuel ratio (AFR) due to its chemical composition. The stoichiometric ratio for gasoline is approximately 14.7:1, meaning 14.7 parts air to 1 part gasoline. For ethanol, this ratio is about 9.7:1. This difference means that when using ethanol, more fuel is required to achieve complete combustion.

Changes in AFR with Ethanol Blends
When blending ethanol with gasoline, the AFR shifts. Here’s how different ethanol blends affect the stoichiometric ratio:

Ethanol BlendStoichiometric RatioChange in AFR
E0 (0% ethanol)14.7:1Baseline
E10 (10% ethanol)14.1:14% leaner
E30 (30% ethanol)13.5:18% leaner
E50 (50% ethanol)12.5:115% leaner

Effects on Engine Performance
  • Lean Mixture: Ethanol blends can lead to a leaner mixture, which may cause incomplete combustion and engine overheating.
  • Fuel System Issues: Ethanol is hygroscopic, meaning it absorbs moisture. This can lead to water accumulation in the fuel system, causing corrosion and performance issues.
  • Increased Fuel Consumption: Since ethanol has lower energy content, engines may require more fuel to maintain performance, leading to decreased fuel efficiency.
Mitigation Strategies
To counteract the effects of ethanol on AFR, consider the following:
  • Adjust Fuel Delivery: Modify carburetor jets or fuel injectors to accommodate the increased fuel requirement.
  • Use Fuel Additives: Additives like Biobor EB can help stabilize ethanol blends and reduce corrosion.
Understanding these factors can help in managing the effects of ethanol on engine performance and longevity.
 
As LF says, it's the temp sensor for a booster plug device. I'm guessing you didn't know it had one fitted! If you follow it back, it's probably plugged into the air in take temp sensor.
 
Which is all very well, but where should the reverend gentleman stick it?

Presumably the clever people who designed the motorcycle did not expect it to dangle in fresh air and rest on a header?

It's an aftermarket accessory - not OEM fitment. It's usually cable tied up behind the fairing somewhere.

Follow the cable it will be plugged in on top of your air filter
 
everytime i come across these , i unplug them , set-up the fuel injection , and give the bike back ......and wait for the punter to complain ( i do the same with P.Commanders ).
i did a Cali once sent him home, going test the top speed . he said 98mph ! then he said it had 1 of these , i hadn't spotted it .
came back a week later , tested it . put that bit you see in 60 deg water , diagnostics said 6 degrees !
unplugged it , did a FI set-up , sent him hom , 125 mph .

After all the piss taking.
See, we do help people on this forum!

Its not true what some say :D
