Engine Stalled

I was slowing down before an intersection, going about 25mph then all of a sudden, the engine cuts out.

I have a 2003 Speed Triple. Any thoughts would be appreciated.

Yeah mine does this too. I don't know why though!

I had a similar problem last night.. was riding in a metro area, lots of stoplights.. I stopped for a second and turned of the engine, coming back to the bike a few minutes later. When I turned the bike back on, the temp read about 90 C, and when I tried to start the bike it would start, idle for a fraction of a second and then die. yikes!

eventually I had to start it and hold on the throttle until I was moving. any idea what could be causing this?

yeah i have the same problem from time to time. It only happens when the bike is warm and i take off from a stop. It will stall and start right back up with out too much trouble

When I picked up my S3 a couple of weeks back, the dealer told me that the bike will stall if you quickly rev and close the throttle (espically when not under a load).

My dealer said he learned at the Triumph service update that he attended a few months back that this is caused by a leaky boot from the injector to the block.

The fix is to replace the leaky boot.

This might be the causingstalling problem some of you are seeing. Probably worth a call to the dealer to check it out.

later.

hi to everyones,
i have a friend here in naples who has had your same trouble.
the dealer replace something on butterfly valve body(sorry,but i don't know the right term in english).
i try to understand you:
it was about the sensor that read the position of the butterfly valve.
somenthing about the seal of it

sorry for my bad english.
take care

It only does it on mine when it is getting hot. It will not maintain a smooth idle. It only happens occasionally, and then it make work fine at the next light. Other than that my bike is outstanding.

yes i have had this happen to me just weekend. i think the problem is that down low just off idle up to 2000rpm they may be getting a bit much fuel this is because the computer system only has a few sensors to tell the computer how much fuel to delver in the higher rpm this system is acquit i myself will be trying a few things to help over come this so if any one Else has any ideas i will be interested to find out

My 2001 S3 was fine yesterday. I took it for a nice long ride and life was good.

When I started it this morning it idled for about a minute then died. I restarted it several times and it wouldn't idle it just kept stalling. I'd start it and hold the throttle open a little but I could tell it was having trouble ... then the engine light came on followed by a very unpleasant burning odor.

After wiping the tears away, I pulled myself together long enough so I could phone the dealer to come and haul it off for a visit to the mechanic. They are coming tomorrow.

I read that disconnecting the negative battery terminal may help a poorly idling S3 in some cases:
"Problem: FI (fuel injected) Bikes dying at idle - The fuel injected Triumphs will suddenly develop a problem holding an idle, dying at stops.
Possible fixes:
Disconnect the negative battery terminal for a minute (maybe only needs to be 5 seconds or so) and reattach to reset the program and correction maps in the ECU. The ECU will revert to the original correction maps....
Sometimes the low speed / small throttle / low rpm circuits in the ECU will tune themselves into a knot - causing the fuel injection to lean out or richen up excessively, enough to kill the engine before the ECU can recognize that the mixture is wrong. Once the mixture is way out, you are stuck..."

Kind of like rebooting your bike, has anyone tried this for their problems? I'm debating whether or not try this... I need to be positive that my bikes ailment can be fixed easily.

I remember doing this for my car a few times, but never really thought about doing it for a bike.
