Problem with '03 Gixx1k

This is the first real issue I have had with this bike and I am stumped.

It seems that I have some sort of intermittent electrical problem that causes the motor to die while riding. This is an '03 1000 with 18,000 miles on it and is basically stock, other than a Yosh slip-on. It has never been crashed or damaged in any, and I am the original owner.

It has happened several times, the latest time was today. I was going about 50mph, just cruising at light throttle, and the motor stuttered for a split second, then died altogther. The tach dropped to zero, however all of the other gauges still work and I can usually restart it within 10 seconds. It did take about 10 minutes to get restarted one time, but that it was the only time it has taken the long. This seems to happen more frequently when it's hot out.....say 85 degrees or more.

I am not getting any codes and I have been through every connector on the bike, and applied die-electric grease while I was at it. The battery terminals are tight and none of the connectors show any corrosion. I have not metered out all of the sensors since I should get a code on a bad sensor, however one dealer says that the crank sensor can go bad without thowing a code, the rest of them say that is BS. I have no idea what the truth is since every one seems to have a different story on this one.

I have had it in the shop and have talked with several others and have still not been able to get this fixed. Based on what the service manual says and what I have checked I am thinking there are only 5 things left that could cause this since most of the sensors will only throw a code rather than killing the motor if they are bad. The exceptions being the Crank Sensor, Tip over switch, and the kickstand switch. My suspect list is shown below, with the crank sensor at the top of the list since the tach is dropping to zero while everthing else continues to run. I believe the fuel pump stays running to, but I can't be sure since that is very hard to hear while you are moving.

1) Crank Sensor.......maybe
2) Tip Over switch......maybe
3) Kickstand switch.....Pretty sure this isn't it.
4) Bad ECU......maybe, but I hope not ......expensive!
5) Bad wire somewhere in the harness........pain in the ass to find.

Has anyone experienced an issue like this and if so what was causing the issue. I may be able to borrow an ECU from a friend of mine, but I am not sure yet.

I really love this bike, but I'm running out of options and can't afford to have a every dealer in town test it only to find nothing.

Thanks guys.

I wouldn't rulte out the kickstand switch. Had a friend with that EXACT same problem, and it turned out to be that.

Take some beer and Beef over to Blitz's house and after the cookout I'm sure you two will figure it out

Jealousy gets ya nowhere :P
















Anyways, back on subject here.

If the bike has a Power Commander then I would start with that, next (or in conjenction I guess as the PC would read throttle position) would be the TPS adjustment and then mebbe look into the other items you have listed. ECU failure isn't very common and sidestand switch problem is rare (but not impossible as I experienced some years ago).

If yer at altitude then the fix may be as simple as a throttle body synch and idle adjust - seems simple but sometimes I overlook the easy stuff when I get all pissed off tryin ta finger out stuff like this.

If the bike is loing electrical ppower when it dies then you will likely never see a fault code BTW (which is also why I would first start off by unplugging the Power COmmander and see if the problem persists - if of course the bike even has a PC).

The problem with it is the intermittent nature.

We rode 140 miles on Sunday and the bike ran great. It was pretty warm on the trip home and nothing, nadda, zip.

I've been thinking about it, and going through my manual and I'd override (in order):

1) Tipover switch
2) Side stand switch
3) Gear position switch

On the zx-12 those are all part of the interlock system and if tripped will:

1) Shut off the fuel pump
2) Shut off the fuel injectors
3) Shut off the ignition

It just doesn't feel like a CPS to me...

I've heard the tip over switch on these can give you fits , that's what I'd check first .

what weve found is exactly thyi in this area

im sure you wash your bike
remove rear seat

there are 2 sets of connectors
if you will notice they are at an angle
facing uphill at the same slope
as your undertail & seat

condensation when you bike sits(hours.... days...until the next time you ride)
forms in that area
when you wash your bike water drains to that area

those two plugs get wet & collect moisture
there is NOT a lot of slack in the wiring

you will need four(4) things
a 1200watt hair dryer
some wd40 or crc contact cleaner......not a lot
some pipe cleaners
some dielectric grease

simply take the connectors apart clean them as best you can
with contact cleaner or wd40
you really dont have to use a lot
if any connectors are corroded or "blue or "green"
pay special attention to them........use the pipe cleaners

when done apply generously but reasonably the grease
"dielectric" at your napa store

reconnect usually problem solved

good luck

This has been tested by 2 different shops while on a dyno.....so far no luck there, but still a suspect. I will swap with a buddy of mine to test that out shortly.

I was hoping to find something like that, but I went through the entire wiring harness last weekend and found no evidence of water or corrosion in any of the connectors. I applied dielectric to every connector as "insurance" for the future, but I still have the problem.

I swapped ECU's with a buddy of mine that has the same bike, hopefully a few days of riding back and forth to work will eliminate or prove that as the problem quickly.

On shop in particular suspects the ECU it makes some sense because once the bike stalls it cannot be restarted until you turn the key off and back on, like the computer needs to be reset. Once you do that the bike fires right up, however I believe that the Tip Over Switch can cause the same behavior so I will swap that with my friends bike too if the ECU thing doesn"t pan out. If I do that I will check the wiring with a meter at the same time just in case.

Electrical bugs are a pain in the ass!

Thanks for the help guys.....keep the ideas coming!!

The fix I read about for the tip switch was to take the cover off and fill with silicone ( pin in the middle ) to stop it from ever working again , some of the guys were having their bikes shut off when they hit bumps mid corner ....

I remember reading about that one too.......that might be a good idea in this case.

I believe the TOS is the one right in front of the battery tucked under the rear of the gas tank isn't it?

As far as the 12 goes, you are right about the Tip Over Switch getting triggered requires turning the key off and then back on as well to reset the computer.

HI DENVER!!


LOL Papi!

The Suzuki tipover switch works when it SHOULDN'T and the Kawasaki tipover switch DOESN'T work at all.

Ain't life grand?

That's 40 mph, a 360 flip for the bike and a 20 ft. slide down the side of a mountain and the motor never shut off.

My 12 now has an ignition cutoff.

Why ? If you hate it so much that you throw it off the side of a mountain - who cares if it's still running ....
