some of you may remember my original post. it read:

so, i just bought the 1000 v-strom. in the past week, i put on 1000 km and i've noticed a disturbing problem. not to be confused with the thumping experienced at low revs, but, under 3,500 rpm i'll occasionally hear a "click" and the engine will cut out for a moment. if i pull in the clutch, like at a stop light, sometimes the engine will stall. i upped the idle speed a bit, so it no longer stalls, but the "click" remains and the dead spot really concerns me. what's worse, the problem is intermittent, which means every mechanic believes i'm crazy. any thoughts?

the most helpfull reply came from big b who wrote:

Hate to tell ya......but you are describing the "exact" issue that plagues the 1000. There are more threads and info on this subject, that your eyes would go blind from reading too much! Laughing Tell the dealer to sync your throttle bodies "they will need it", check the TPS adjustment, and make sure that "both" throttle cables are adjusted correctly. Also make sure that the throttle body boots are on tight. Set your idle speed between 1100 to 1300 rpm. If they actually perfrom these adjustments, you should be much better. If not.......you need a new ECM, PCIII or get reprogrammed with a tuning box. ALLOT of dealers are replacing the computers under waranty. Suzuki is aware of this problem, but has not issued a recall, and WON'T. Be a royal pain in the ass to your dealer.....if they think you are crazy, tell them to checkout this website and they will get an education!

i showed that post to my dealer and they took a look at the bike. they found no fault with the machine, but they "reset the low speed and off idle fuel." since then, the bike has been somewhat smoother, but remains intermittently unresponsive when "blipping" the throttle between downshifts. one time it even back-fired! then, just the other day, after riding at highway speeds for about an hour, i geared down for an off-ramp and, while turning, the bike acted like it was out of fuel... sputtering and completely unresponsive. this is very disturbing to me, even though the problem happens only occasionally. any more suggestions before i go back to the shop?

thanks.

Maybe seems to be a silly question and also I did not remember if somebody warned you already but it would worth to have a look on the electrical connections. In first place the battery cables. Are they tight and not corroded the contacting surfaces? Many problem used to occur because of ground-failures and we know the body/frame is not used for that purpose on the Strom so every "negative" wires need to be correct.

Mine has done similar antics. The stalling on an off-ramp, the click, the backfire, all of it. I'm nearing 3,000 kms on mine now and its getting better. I plan to sync the throttlebodies this weekend and, hopefully, improve it further.

Oh, and the ass-suck dealer I took mine to for the 1,000 km (600 mile) service told me the same thing, "there is nothing wrong with your bike, they all run like that". We all know they can run better, my dealer, and yours, was just too F#$%ing lazy to actually do some work on it.

I took my DL1K in for the service appt. I told them my bike was hiccuppin and fartin and slow speed stalling :( , they put it on the "puter" and checked everything , remapped the F.I. and adjusted the cables , now runs like a dream :D . very happy with Cycle Wise inc. in Bridport Vt. Oh Also , They saved me the print out of the Factory settings & one of the re-map in case I needed to go back to that point for any thing that might come up further down the line....ride often & ride safe. Jack.

Good points from all. Hopeless, are you saying the dealer did or did not check the things Big B stated, TBS, TPS, throttle cables?

All three of those things could not really be checked right by simply looking or feeling the throttle. THat is what my dealer did, looked at the throttle boots for 30 seconds, "yep they look good", snapped the throttle a couple times, "yep feels good". Doing them right at home really helped. Later I also got the remapped the ECM from Suzuki which seemed to help. Learn how to do the throttle body synch, and adjust the throttle cables, your time will be well spent and at the very least you will know it is done and correctly.

My Strom acted the same way when I first got it several months ago and the only other thing I can say is when I had about 2000-2500 miles on the bike it seemed to really smooth out and the "clicks" didn't happen.

uh, that's great advice. the thing is, what does TBS and TPS mean? and throttle body synch? (is THAT TBS?) remember, my last bike was a KLR 650. My tool kit consisted of three different sizes of hammer. thanks for the replies, though.

TBS= throttle body synch...TPS= throttle position sensor.


Were they calibrated hammers???? :lol:

A Possible Fix

HL - This may be the answer to some of the problems you have encountered. The bike is delivered ridiculously lean at idle and into the mid range. This certainly adds to the problems many encounter at 3800 RPM's. The Techlusion unit is easily installed and does make a discernable difference.

Fl_Strom, I recently installed a Dale Walker provided Techlusion from Doebeck. The off idle and mid range gains were impressive and there were minimal effects on the fuel mileage.Dales' setting were dyno proofed. I believe the PC has it application. Racer who need to re tune for different track conditions and environmental constraints benefit from a PC. For the rest of us who deal with factory imposed super lean conditions, the Techlusion is the answer.
Hope this helps.

hopelessly lost here (logged in under my dad's account.) well, i don't know for sure, but i think the problem just... uh, went away. it's burped a couple times after i had it at the dealer, but then started acting normal after about 4000 kms. weird. nice. but, weird.

Hopelessly, I'm not surprised that your bike is clearing up on it's own. My 06 gets smoother as it gets km's on it. 3400 so far. My bike is really sensitive to TBS, and runs like a dream when it is set right. Just ride it and enjoy.

Maybe the 06 models, but NOT the 05 models. Chances are, that the hiccup, stutter, burple, cough etc....WILL return. The cooler the weather, the better it may run....when it gets hot, it may run like poo.

You need more fuel with the air coming in!!!!!

If it's the ECM, the bike will run much better in cool weather and especially after it has sat for several days, presumably because it cools off to it's core. But after running for an hour or so in warm weather the symptoms will return.

Dan_C posted the other day there's a Suzuki tech bulletin on this now, and others have reported a Canadian ECM exchange program for some time now.

There are still skeptics out there who don't really believe the ECM is the problem. They are never in doubt but wrong, in most if not all instances of this problem. My dealer was as skeptical as anyone but after doing all the obvious things, called Suzuki who (after some conversation) replaced the ECM on my K4 without charge.

(hopelessly lost here again :D I should mention that i have the 06 strom. my dad has the 05) nope. problem seems to have disappeared. as for running like poo in warm weather... i've been on the road for the past week in 30 degree celcius temps (i'm bad with conversions, but for all you fahrenheight junkies, that means HOT) and i've been riding every day. the problem might return, true, but obviously not because of hot weather. now if only i could find an adjustment on the windshield i like! (i tried drilling holes to lower it like my KLR. BIG MISTAKE!)

eating crow

ok, ok. i was wrong. the problem still exists... just not nearly as bad as it once was. there seems to be no link between perfomance and temperature, however. the bike pooped and coughed three times over a one and a half week trip across the great plains of saskatchewan and manitoba. i suppose i can live with that. my KLR worked better, though.
