Hi, When i fire the bike up first thing in the morning or when I am leaving work, the motor fires up as normal but them after a second or two it will die down to almost stalling.
I sounds like the choke isn't coming on or it is loading up.
Then a few more seconds later the revs come back up again like normal as if the choke has kicked in.
Dose anyone know what is happening here or has it happened to anyone else?
The bike has only done 2,200 km and the only thing done to it is the computer flashed and Yoshi pipes .
Any information is appreciated.
Cheers.

Been lots of looks, but no replys, so no-one with the tech know-how has seen that can help . . . yet.
So with very little to add, I'll start. The "choke" is not a choke, it's a fast idle, which means it just raises the the idle without changing the air fuel mixture. The same as winding on the throttle a bit, and does just that.
hope you find the problem and someone here can add a bit of more useful info. 
give it some revs at start up, as they need a few revs to get the oil up to the top of the engine from cold. (2000-3000rpm)

Was it flashed by a competent tuner?
Saw one that was backyard flashed, once the bike got hot it wouldn't run properly, finally ended up with a blown headgasket .....

Yoshi mufflers or full system? Was this a Yoshi 'tune' map mod or a full mapping done on a dyno? Mine is at 4500kms now and I have R77 mufflers and a Yoshi mapping tweak, but none of the symptoms you describe.

If it's a Gen II then it's a known problem .............. even reported by journos in the first ride reports of the 08 model. Had a guy in Bundy had the problem and not sure how he sorted it or if he even bothered after speaking with me, but it's related to ICS setting.
Needs ICS to be checked and voltage logged during warm up with SDS tool and then ICS to be reset.
PTC heater again checked with sds tool. Would also check that ICS is not sticking when cold ................. do not disconnect ICS from loom within 5 secs of switch off or it will lose it's setting and can only be reset using SDS tool. This will then bring on FI light (Again if it's gen 2)

Cheers, yes it's the 2010 model.
Only just started to happen in the last few months, very odd.

Could be the colder weather coming upon us that has made the prob more evident ?
Would have the basic checks done first as if the base settings are out then the cold system will not function correctly. One of the reasons for the "new" ICS set up on the Gen II is to aid cold starting but like all things the more technical they get usually the more prone they are to gremlins also.
ICS may have lost it's base settings or may not be holding the set rpm value, temp sensor could be faulty etc.
During test you can set ICS to different rpm to confirm it identifies and also holds the value slected. I know you would not have an SDS tool just listing causes and the fix for them. Most of the Gen II set up needs SDS to confirm and check. It's the way the manufacturers are going now ................. tending to lock the owner out and also non dealer repair shops. Suzuki will not sell an SDS tool to any one except a dealer which is almost / if not a breach of the trade practices act.

Mate, I got a 2010 model as well with full Akrapovic system. Had an ECU flashed by Peter (fasterfaster) and have zero problems with it. The temperature drops here to 8 deg at night but the baby starts without any problems and purrs like a kitten. I sggest you senf the ECU to him to have it checked. It will be the best money spent rather than dealing with some grease mokeys at the dealer. You have it flashed already so it will not be covered by the warranty anyway.
Cheers,

Checking the ecu will not show much its as pete says the operation of the idle control valve which needs the suzuki diagnostic system to view the operation of the valve while the motor is going through the warmup cycle
flashing can turn the valve off and on but not do adjustments to its operation .

You are absolutely right Maj but I've assumed that the mechanicals are operational and just the flashing someone did for him stuffed it all up which I guess could be the case.

Just a note ................ the flashing doesn't effect ICS adjustment. It's a seperate item it's own that has to be "base" set using the SDS tool.

Pete,
That was me, yes it still does the same, mines not the only one, did get a little better as the motor got a few more ks on it. Dealership looked at a couple of times in the end I learnt to live with it until I can get a free day for you to look at. Time just gets away when your having fun.

Well finally made some free time on Friday rang Pete @ faster faster & off I went.
While flashing the ECU Pete checked all settings, naturally, & found the AFR on idle to be the richest he has ever come across. Pete completed the 1st flash ran her up on the dyno & found she was still running rich @ around 180k, the ecu was taken back out adjustments made & refitted. Ran the bike up again & the changes soon proved themself in AFR, HP & FtLB. Had the TRE, pair valve & oxygen sensor turned off while the flash was done.
Pete then ran her up one last time to ensure all settings remained the same. All good, after a coffee & a chat about days gone by (GS & GSX range, katanas, EFI oh the list goes on) off I went to try the new settings. I found @ 1st a perception the bike was sluggish until I looked down @ the speedo & rouded up a few slower cars, impressed. What i have found is there is no lag & she pulls all the way through hence the feeling of sluggish, no snap it on wait for the magic RPM for the motor to show what it has. In short the power curve has been smoothed out with the help off the remap & no TRE.
Now had to wait until morning to try the cold start keeping in mind the idle was way to fat in fuel settings. About 7 degrees this morning, whats cold for QLD, out I went turned on the ignition waited for the fuel pump to load up & fit her in the guts & she started 1st hit :) I have never had this this in winter unless she had been started that day.
I would like to thank Pete for his time listening to me regarding the bikes set up explaining what we could expect from the new set up & how the map should resolve any issues. It was also nice to sit down for a coffe & chat with a guy who is straight up & down & if he dont know he will say so & find out. Cheers Pete 
Steve

It certainly helps to have someone who has the right tools and knows how to use them.
I hope his rottweiler didn't try and hump your leg!

Steve no probs and a pleasure ................... was good to chat about the old days .................. the one's where if you didn't get your ass of the seat it didn't go around the corner 
PZ2's being the front and PZ3's the rear flavour of the day to cover the pizza cutters with. Have to do it again soon
Camel no he didn't much to my surprise as Steve is much better looking than you also .................. he must like the dog to dog appeal
