2009 stalling intermittently
Last Fall I had a few issues with the bike not so much as stalling, but stuttering at a stop light...I think it was fouling the rear cylinder, PC5 map too rich....
Skip ahead now to this riding season, nice clean running plugs, bike runs strong. Started with ZERO map, let auto tune do the rest, revised map about 9 times now, runs great.
BUT, yesterday, it started to act up again, but different than last year....
Drive for 20 mins, pull in clutch and let the bike idle down to 1000rpm and it stalls.
It does this at any speed, as I had lots of time yesterday to test this. Cruise in any gear, pull in clutch, bike idles down...idles at about 1000rpm for a couple seconds then cleanly stalls. Release clutch and it fires back up.
Stop the bike with clutch in (I also checked with clutch out in Neutral this morning as I coasted to a stop) and it idles for 2 seconds then stalls.
It FIRES right back up when I start it back up. Only exception was this morning it seemed to turn over but not fire, then finally fired up.
Last night pulling into my driveway, kinda coasting, pull in clutch and it stalls...this morning pulling into work driveway, same thing....
Kinda like as if the kick stand switch was acting up or a neutral switch?
Help!! LOL!
Thanks

my 09 had a similar issue and i had to clean the throttle body. i forget the name of the sensor behind the throttle body blade but it gets gummed up and gives idle issues. i used MAF cleaner - but any electronics friendly cleaner will do the trick. I cycled the bike on and off a few times with the throttle all the way cranked to open up the sensor (by this i mean cycling the on and off switch to hear the pumps prime not actually cranking the bike over). let it dry a bit then fire it up. you will see some black smoke come out your exhaust. thats all the crap you just cleaned out.

Good ideas guys.
I have a SE air cleaner...and I routed the two breathers to point into the TB with 3/16 steel brake tubing...this could possibly be causing a dirty IAC....
Will look tonight!

Bike basically stalls anytime once it's warmed up as soon as you bring it to idle...I rode home without the embarrassment of it stalling at the lights by keeping it idling at about 1200 rpm.
As I pulled the clutch in just at my driveway, not paying attention, sure as heck it stalled! LOL
Got home, pulled off SE airfilter, pretty dirty, and gave the MAF a good spraying of cleaner a few times and did some laps around the block...seems fine. Have to wait now for the rain to end later this week.
In the meantime, might order the K&N replacement HD0818 filter for it....

That is called the Idle Air Control module. Clean out the IAC hole in top of teh throttle body with throttle body cleaner and it should cure your problem. I had that issue on my 05 with EFI. Cleaned IAC port and all was good.

this is an 09 103....I didn't notice any holes in the TB....and yes, I know what I'm looking for. I admit, I could be wrong.
From what I could tell, the idle is controlled by a stepper motor on the side, controlling the fly by wire and regulating the idle speed....
Correct me if I'm wrong!
Thanks again

Looks like Hogpro & a few other members are on the right track my bike does the same thing a couple of times a year & I just clean my IAC & she's back to normal.
