Stalling
From what I see in those pictures, Triumph has used a micro switch, actuated by a piece of spring steel when contacting the clutch lever. (One micro switch picture has a blue actuator button and the other a black one) Pull the clutch in and it forces the spring steel to move out allowing the micro switch to "relax" and "click". Those micro switches are known for getting contaminated, causing intermittent contact for clutch safety circuits, brake light circuits etc. I have taken several apart over the years to "clean the contacts" with great success.

If you can unplug the switch you can check to see if it functions with an ohmmeter removing any guess work.

I imagine Triumph uses one switch on the clutch for the clutch safety (inadvertent startup in gear) and also (from what some of you are saying) to add fuel when idling with clutch depressed to prevent stalling??? Knowing if the clutch is normally open or closed with the clutch relaxed, you should be able to test the switch without removing it by seeing if the bike can start in gear or with the clutch not depressed??? Just guessing here without access to prints.

I guess how long u run it depends on how cold it is.
recommending the 12 minute tune (only ) for stalling problem.
and we do not know if this will work or won't work till a few guys try it.

Yup. Before replacement would start without clutch pulled in.
 

I would say this is perfect.
 
With the bike in neutral and starts
With clutch in it is ok
And does not start with clutch out then switch is ok
If it is not working take it out and beat up on it stomp it a couple of times and if thaat dont work then jump the wires. Temporarily to start
Lol
 

Brand new R3 owner here and after day two I get an engine check light. I figure it's because I had the battery disconnected, but it came on during a ride (hmmm). Day three and I filled her up and the gauge is not responding.

Deja Vu.....

Got home and tested and, yes, it starts without the clutch pulled in. Not my first rodeo, as this came up with my Roadster when I finally figured out why my gas gauge quit working.

Fuel Level Indicator Not Working - Clutch Switch/Solved!

I've had the tank up and down a lot lately fighting various gremlins. At one point the fuel level indicator stopped working. The low gas warning light still comes on, but the digital display and miles remaining is no longer functioning. I've notice that if I lift the tank it will reset (not...

Triumph would do well to monitor this site. I can't believe they put what looks like an even more fragile switch on a new generation machine. I'm hoping to fix the existing switch, but guess I'll order one now before the dealers close.

I'm too far from a certified shop to have this done under warranty, so I guess I'll just eat the cost. Less than 200 miles on a new bike when this began....
 

the parts r not very expensive
no one has done a video but i would think not to bad
there's 2 clips one or both is spring loaded and then u have the switch.
i think most r buggered while wiping with a towel.
