I'm posting this because according to this thread:

http://forum.svrider.com/showthread.php?t=90386

it sounds like quite a few people have had this problem.

Basically the bike will start and run like normal and then later when coming to stop or anytime it goes to low RPM it will stall.

It will restart with a hit on the starter button and some quick throttle again to keep the RPMs up but if the rpms drop it will stall again. Keeping some throttle on at stops will keep it going.

Turning off the key and turning it back on again seems to clear up the problem but then it will come back intermittently (like it won't happen on every ride but sometimes will pop up).

I am hoping someone has had this fixed or found a diagnosis/fix for it ! !

Thank you

Ed

Mine does this too. I'm interested in seeing if anyone has a solution. It seems like it is mostly an '05 problem.

i'm having a similar problem with my 2006. I first noticed it when getting off the throttle when shifting. it's a recurring problem. it also happened once when i was idling at a stoplight. i hit the starter button several times before it would start again. it's as if the run switch was shut off. i casually mentioned this to a salesman i know at the suzuki dealership and he said it's probably the sidestand switch. i haven't had the opportunity to get it checked--too cold out right now.

I started to experience this problem as well. I just got back from 100mile ride and once I got into town my bike started to idle at 900-1k, and when I take off i'm only running on 1 cylinder, and BAM both cylinders kick in and my head snaps back.

It just started today too, super weird. I'll have the dealer ship take care of it. They still need to replace my radiator.

This sucks, its happening to me once out of 3 trips. Its totally random when it feels like doing it. I tried to adjust my idle but the problem isn't there.

You guys are all saying that it will crank but is still hard to start after it stalls? If you are absolutely certain that it is not the fuel (water) and certain that it is the act of turning the ignitkion off and not the time it takes to do so fixes the problem, i'd guess it is a faulty sensor of some sort or even a bad ecm. start assembling known good used ones and swapping. In the meanwhile, go though each electrical connection and thoroughly clean with contact cleaner spray. Likely, it is a very transient condition that is confusing the ecm which is obviously reset with the ignition key.
I doubt that it is the sidestand switch; that it more an on/ off thing.

I still think it is either a TPS or CPS issue.... it should be interesting to track down though.. I'm not so sure it is the sidestand though.... if it was it would not start again even after turning off...

the only way would be to test the CPS and TPS for faults... which I suppose is difficult if the bike doesn't throw a code... have you tried running the bike in dealer mode for a while to see if it captures the code when it happens?

EDIT:
I have a question..... of the people who are having these issues.... how many have adjusted the TPS themselves? as per the well known mod/adjustment?

I'm just wondering if the 2 go together...

My bike has not had this happen yet and it is an 06... granted it has low miles (Less than 2000) so perhaps it will show up later... but I also haven't done the TPS adjustment either...

Hi Ed,
I would do an tps adjustment next. I did mention in that thread that idle fixed my issue, but the dealer did do a tps adjustment a few weeks before, saying it was little off. So maybe it was a combo of both fixes? My bike is an '05 too. I see you are in So. Cal, do you live in Los Angeles?

I have adjusted my tps, maybe that's it. I thought it might be my tre, but I removed that and it still does it.

I could try the dealer mode thing, but when this happens the FI light doesn't come on so I doubt it would give me a code.

nope.. they are those annoying security torx... dunno how they are security since you can pick up those tools at most hardware stores...

it would be interesting to see is people doing the TPS have more of this kind of problem than others... if so I wonder what would cause it... perhaps dirt or moisture getting in the area? who knows... I'd make sure the area is super clean and dry before doing it though just in case this is the cause...

Ok, I just did the TPS modification/adjustment. Got it adjusted to activate the fuel injection at about 1500 rpm . . idle is set at about 1300. . .we'll see how it goes. I did have the idle set to about 1600 but I have reduced it since I've done the TPS. . .keep your fingers crossed

Re: Engine stalls when idling, like at a stop, Goes away when turn key off & back on

Oh tay I have a update. I went to my dealership to have them install a new radiator, I told them about my piston problems. One of the mechanic assume its a value adjustment problem. But they found out that was not it. Then he checked the spark plugs and wire, when he went to reassemble the wiring some how was no longer able to put it back together!!

I walk up to see if my bike is done, they reply "ummm we cant get your bike started, can you leave it here" I said "HELL to the NO, I need my bike in operating order!" Long story short the manager was able to get it to run again.

Then they inform me that the problem lies in the COIL & SPARK WIRE. They have ordered the parts and should be here 2-3days, and we will see if this solves it.

I'm still under service warranty, so there is no cost to me -> racked up about $1,400+ in service and parts this week 8) not including 15 services I have done with the bike

Will keep everyone updated to see if this is the fix. I'm not sure if ASC has tried this.

Ok . .. here is an update. . . after riding aboaut 36 miles (18 miles each way to and from work) since my last post the bike has not stalled out. . . I hope that this was the fix (adjust idle plus TPS).

thanks to everyone for your help.

Hmmm.. I'd think the "adjust idle" component was the relevant one, considering the problem occurs at a throttle position of zero.

It was adjusted to 12-1300 when the problem was happening. I adjusted it up to 1600 until I was able to do the TPS mod. Then at the same time as doing the TPS, I adjusted it back down to 12-1300. . .this would indicate that the TPS mod had something to do with it.

Or perhaps, it is still a problem, just an intermittent one, and I have just not had it come back again, YET.

Which I hope is not the case.

Re: Engine stalls when idling, like at a stop, Goes away when turn key off & back on

Okey I have a update on my status with the 1 cylinder until 3.5k rpms.

Dealership finally fixed it, they ordered a list of parts and installed them:

1x #33410-17G00 COIL ASSY,IGNIT
1X #33510-17G00 CAP ASSY,SPARK
1X #33541-23E01 SEAL,SPARK PLUG
1X #33542-17G01 SEAL,HIGH TENSI

After the install I took it for a ride and the problem came back!!!

So I busted a U-turn and told them bike is not fixed yet. So about 20min later bike was ready again. I asked the Tech "what was wrong". He replied "It was not plugged in all the way".

Rode for about 20miles and I could not get it to cut out, so far so good!

You've never turned your ignition off?! Or do you mean it keeps coming back even after you do?

Re: Engine stalls when idling, like at a stop, Goes away when turn key off & back on

ive never turned the ignition off and back on when the problem occurs my bike just wont idle @1200 rpm without a surge i adjusted the tps this past weekend and rechecked it this evening i can set my idle at 2000 and the bike does great but any thing below 2000 it surges and has a hesitation when giving it throttle, the engine then sounds like its firing on one cylinder..

Re: Engine stalls when idling, like at a stop, Goes away when turn key off & back on

I have the same problem with my 06.

After a long ride, it would die while idling at a stop light.
Going to adjust the idle speed/TPS this weekend and see if it helps.
