f650 sputter and/or dies once in a while ???

My girls f650gs will sometimes sputter and run bad for a few seconds at a time or just up and dies when she lets it go to idle. Seems to do it cold or warm. The bike has about 9500 mi on it and never had anything but oil changes and filters. Never been dropped,kicked, or yelled at (unlike me). We have never gotten a light or any warning. I have a gs911 but doubt it will tell me anything. Always run good gas and has been doing it for the last few fill ups so that eliminates bad gas. Any thoughts on this ?

This is a twin 650...right..... If yes.... Those symptoms are like the charcoal cannister issue. That is how they stall....rolling off the throttle. The CC could either have some water in it...and not draining properly.... Or some fuel from overfilling..... Then when the purge valve opens ( with fuel) the CC sends in a very rich mixture...... Does is happen under all riding conditions....sun rain...snow...etc.... If this is for the single 650....then disregard my above statements....

If it is the single, then it sounds like the Idle Control. Part number 13537679998. I had similar stalling issues (warm or cold).

Throttle Position Sensor reset is needed.(TPS reset). Turn key on, open throttle all the way and close, Slowly 4 times, then start bike. 4 times might be over kill, but so what. That should fix the problem. Good luck.

Other thought:

One of the ZFE / ECU firmware updates was to help stalling/drive-ability.
It might be worth applying the latest firmware.

Although ... I have heard that the very latest version of the firmware also does away with the "miles remaining" function if you have the on-board computer....

Warn her of this if she has the OBC ... so you don't get yelled at for something that does NOT deserve it

Do I shut turn the switch off then on before starting or just go ahead and start it after doing the throttle roll 4X ?

Yikes , we count on that miles count down. I ride a 1200 GSA and she many times lets me know how many miles to empty so I can guesstimate our next stop. I know its not 100% accurate but so far we have not run it out. I keep a rotopax under my right bag incase we run it dry. That is one feature we hate to loose.
I had a update on my 1200 last fall, it would die once in a while, so far so good, and no loss of computer function on that. Guess I will do the throttle position first then canister next. Hopefully other options get mentioned before it goes back to a dealer.

No, just start the bike after opening & closing the throttle.

My 07 F650GS left me hanging this morning with these symptoms. It would start then die if I didn’t give it a little throttle. But if I came to a stop it would die again if I didn’t stay on the throttle.

So….. any update? Did the throttle reset work for you?

Mine did the same thing about a year ago at 20K miles. Everyone (including the mechanic) thought it was the throttle sensor. It wasn't. It needed a new coil. Have it checked out as mine was stalling while riding slow speeds.

Your "07" isn't a Twin, right?

Single cylinder, twin spark.
I did the tps reset last night and it seemed to work. Starts and runs fine,. Let’s hope it stays that way.
But what are some of the solutions other people have found for these problems?

You need to ask in "Thumpers"; this is the forum for the Parallel Twin.

So, do you still have the problem after the throttle reset?
