Trouble again, need help please.

I went riding to the U.S. with a friend, N.Y. state and crossed to Vermont, in Vermont I filed with regular 87 grade as my LEMON doesnít like high octane, didn't noticed anything on the way back to Canada-Montreal, today went for a short ride, stopped at friends and installed heater kit, didn't do a full installation, didn't have a connector to connect on the wire behind radiator, I had left this wire on the side when I painted my lemon.
I used some dish soap to help remove the original rubber grips.
I washed the grips and handle bars as I would put the grips over the heated circuit.
Dried the handled bar and grips.
Tested with all together directly to the battery and was ok.
My main job was to remove the grips and install the heater kit, the rest I will finished when I will get the connector to plug into the accessory connector behind radiator.
I was on the way home when the bike started Kicking, and on the lights stalling, she seems to be running on one cylinder and sometimes the second one kicks in giving a jump. (Donít know how to explain well)
Can this be the gas?
Can it be an injector clogged?
Water in the full line?
What can this be?????
When I passed the hose on the bike to remove the soap I didn't use much water, I hose mainly the handle bar and the right side of the fearing.
If anyone has any ideas that can help me, please do as I have enought with this lemon.
Thanking all of you in advance.

Sorry for the bad luck! Several things to check, start with the easy ones.

Check both spark plugs, look at color of tip then plug in socket and check for spark. My Bandit loved to eat plugs.

Probably not fuel, would have started after filling up, but check it or add some Stabil and check your fuel filter too.

Last, if injector is bad (just had my Diesel Truck blow 4 injectors and symptoms sounded like what your describing...sorry) you may need to go to the dealer. I have never messed with injectors on a bike, maybe someone else can chip in how to check them.

Good luck, if all else fails, maybe it could fall over a cliff and insurance would have to buy you a new one!!!

Hope it helps, Roger

First, the V-Strom is designed to run on 87 octane and there have been several reports of problems running hi-octane. There's no use buying more expensive gas if the motor doesn't need it.

The misfire is probably an electrical problem. Your drop may have knocked a wire loose. I agree that checking the plugs is a good place to start. Trace the wires back to the coils, check the battery connectors, try to determine if something is shorting out, etc. etc.

I didn't see any prior posts by you that would indicate why you think your bike is such a lemon.

I post in 2 groups, had problems with this bike from the start.
the bike was running ok since it came from storage (winter).
Ok, I checked what someone told me and seems to be the prob.
I unpluged coil one at a time, unpluging the fist one made no dif on the way the motor was running, when I unpluged the other one the bike shut ride way.
it's the coil that goes to top cylinder. Have to lift the gas tank to reach to plug to test plug if plug works both coil and plug are good, just have to see in the manual hot to test injector.
So it as to be 1 of 3, coil, spark plug or ejector of this cylinder.
I will post more as soon as I have the time to find and come to post.This bike from the start ad rough idling, hight hidling when coming to stop on cold weather but bike at normal temp, ECM was replaced, also other parts that can't remenber, seals, and just noticed today oil leak again and anti freeze, someone tell me if this little things can't be fixed by suzuki????
It seems they don't care as bikes still come with same problem of rough idling but most of the prob is around 3000rpm, most of people noticed that, what do dealers say about this? ho it's the first one, heah right.
Dont' take me worung I like this bike but never expected to have so many trouble from the start, and things that suzuki could fix easy from assembly, that's my believe.
And since they no there's a prob with ecm they should replace eveyone's from free no questions asked, because in the end it gives bad name to them, but I guess they don't care.
Dealer on one repair told me they adjusted the mixture (hmm ecm, did they reprogram the eeprom, they don't have the qualificaton)
It's a good looking bike and she doesn't like to be stoped, that is my first feeling from the start. (staying positive )
thanks to all.

problem found???

funny thing today I tested spark plug and it give spark, even give me a little shock, so spark and coil should be good (maybe not 100%) would have to do other testes.
So since I got new plugs I went a head and changed that one, started the engine and the motor started and reved to 900 rpm, I give some gas and it stayed study at 1200, doesn't seem t respond at peak but is now working on both cylinders, going for a short test run after supper.
So may be the spark plug was working but not very well, she still new, brown color from normal use.
I will post when I kno more.
thanks.

Well, the trouble still there , I noticed most of it below the 2500rpm, unsteady idle.
When give gas to take off, she seems to have no power and about the 2500 rpm power kick in and almost left me behind.
I wonder if could be the injector?
Today I didn't noticed anything at high rpm like the day this happen not even at speeds above 100KM.
If she runs ok at high rpm or speeds above 100 and when I mean high rpm I mean above 3000 or even 3500 rpm.
Can I rule out the injector since gas seems to be injected well?
Weekend of 4 days, no Motorcycle :evil:
If anyone as any tips, please don't be shy.
thanks

The bike drop was last year, and everything was fixed and also new paint job.
Bike was running well, from the storage removal to the problem that started was on the second gas tank.
Thanks

On a carbureted bike, I would know where to start. With FI, there are lots of little sensors that can contribute to stuff like this. It sounds like the injectors are fine if it runs well at high RPM. Since the problem seems to be focused on the #2 cylinder, I would start there.

If you assume that the problem is related to storage you could:

-- Check the rear TB to make sure there's no gunk blocking the primary and secondary butterflies.

-- Put some gas treatment in the tank to get rid of any water and clean the injectors.

-- Check the air box and filter. Varmints like to build nests in them and something could be blocking the rear intake boot.

-- When everything else is checked and cleaned, do a TB synch.

Unsolved, any other suggestions.

I empty the gas tank and put new fuel.
Cleaned the air filter (it was ok)
Is the TP the Position captor butterflies?
The thing is my maintenance book is French (was half price compare to English)
If is what I think, I have to put the ecm in dealer mode, can some tell me if the tool shown is only a jumper?
Tomorrow will add injector cleaner.
Problem seems to be concentrated on idle and up to 2500rpm, she seems to have problem on take of only, or when running on first gear a very low speed and rpm.
Thanks
