Bike randomly shuts off...
2009 zx14 with about 3700 miles. Owned for about 3-4 months so far with no problems. Ridden almost everyday. When I got it from th previous owner It had been down once or twice in the rocks. Low speed crash. So I fixed the cosmetic damage and has been good so far until about last week when I would be riding and hit a few bumps and it seemed to just randomly shut off. And did a lot. It would fire righ back up but just got annoying. Also did it once or twice on the way to work this morning.
I'm thinking the tip sensor could be at fault. Anyone else experience this after a low side?

if not check your kickstand switch, might needs to be cleaned.. mine did same thing off and on... and after cleaning it.. problem went away..

what they all said. with the ignition key off and out of the bike unplug and plug back in every connector you can get your hands on.check to see if any fault codes are stored.

Another common thing to check if it has a power commander under the left dash panel is the ground wire to the coolant bottle bolt.

How about letting the bike sit idling on the side stand. This way, the tip over is at an angle already. You act the bump and move the right bar so as to shake the ball in the knock over switch. If it keeps running, it is not the switch?
First try that. What all are the accessories? As mentioned, reground the piggy if ground is behind the plastic water tank.

I checked the ground on the pcV. I have even giggled the kickstand around while stopped in first gear and it does not react. Only seems to act up whenever i am slowing down/pulling in the clutch and the rpms drop. Because id imagine a loose battery connectionwould do it even accelerating and going over bumps. Only does on decel or slow moving. So thats why im baffled. Ill pull it apart and check the battery connections.

What would i see from doing this? A sequence of blinking lights? I have never checked faults on a motorcycle ecm before..,but have done hundreds of cars :-)

Did you try with the piggy out of the bike's base, stock setting? Since the injectors need a ground, this still sends the piggy hot if you remove ground off the piggy unit. It is a resistance draw none the less. Remove that variable by removing the hot side of the piggy unit. Now take it for a ride.
This is a 'decel' scenario, right? New info reads "only does," and that helps narrow some things down. Try with the pc out of the loop. Go to work and all that. If it does not do it, again, that is a grounding problem is my guess on the piggy side.

It's a horrible idea from dynojet. The problem is the bolt won't stay tight enough to keep a good ground.
That problem happened to a lot of people on here when the zx14 came out.

I ran a seperate wire from the battery ground bolt to the coolant bottle bolt. That gave me a sufficient ground for the PC. Mine would lose ground after first install, never happened after i added the extension to the right side of the bike.
Its an easy fix if you wanted to give it a shot and see.

i just realized that i spelled "jiggle" in correctly lmao, i was like uhhhh why is he talking about laughing???
i will do some more investigations when im not so sleepy and it isnt too hot in the garage where im at. i will let you know what i find asap.
Should i move the ground or anything? or just add an additional ground to the power commander?

Just add an additional wire to ground it so you don't have to hack any of the wires on the PC.

You can easily check if it's the sidestand switch. When it cuts out pull the clutch in and it should run. You might have to thumb the starter again if it's stopped completely but do it with the clutch in, If it starts then it's the sidestand switch.
My money's on the PC though.

Alright---since i finally got time to start checking everything, i have checked everything and nothing was loose.
however i did check my PC5 just to make sure my map held and it did. however i did notice my idle was around 900 on the PC5 screen, so i turned it up to about 1000/1100.
Put the bike in first gear and did the "flick" test on the tip sensor and nothing happened.
Also i found my throttle position wasnt set right for some reason. the minimum voltage was at 1.1xx volts at rest when it should have been .680 volts. i did the TP calibration and it accepted it. and went WOT to set the max voltage as well
I also did notice that until i did the TP cal that my fuel adj in the PC5 wasnt changing at all as throttle changed. now it does.

I think that tps voltage will b higher When u raise ur idle since ur changing tps position with idler screw, could b wrong but I believe after bike is at operating temp idle should be set then tps voltage checked, I'm sure someone will chime in, u did say ur idle is higher than stock setting hence higher reading?

Well...i did even more digging today. as it was 101 degrees outside sweating my arse off. i think i found the problem...an odd and unforeseen problem nonetheless..
so i decided to check EVERYTHING on the bike...so i pulled the fairings and the seat off..just to check for any exposed or loose wires grounding out or something. and i just happened to push on thr LEFT ECU harness and connector and sure enough the bike shut off! I didnt disconnect it or anything. i just moved it to mimic a bump.
upon further invesigation i noticed that the grey TPA seemed out of place..almost popped out on one side. and then i took the connector off the ecu and the little orange TPA on the front side just popped off and was really loose. Wondering if i can just get those two TPAs and be good or would the whole connector and wires be replaced too? all the pins in the ecm itself appear to be fine

It won't pop back in?
The MSD SB6 uses the same type of connector and when I got he bike back together this spring after some winter projects, it wouldn't start. I chased it down to one of the pins in the SB6 not making contact within the connector. It was the ground pin from what I could tell. Anyway, I put a slight bend in the pin so it would press better against the metal blade internally and it has worked flawless ever since. Actually, I placed a slight bend on all the pins... and I mean slight.. just nudged them all up maybe .25mm measured at the ends. Seems to be working. Maybe if you can get yours put back together try a slight bend at the pins on the ECU side to get a tighter fit at the connections?
Stupid loose connections. Makes shit hard to diagnose when it works then doesn't.. plus seriously unreliable. Good luck for sure.

i would definitely give that a try. that sounds like a really good idea!
it will snap back in, but is really loose and i think will stay put, until i hit enough rugged bumps and it jumbles loose again.
its almost as if one of the tabs that hold it on is broken. because the right side connector is on and it STAYS on.
