i have a 2009 zx14 and it stalls when i accelerate. it happens through all of the gears. if i gradually accelerate real slowly then it will stay running but it stalls out all of the time. i took it to the dealership and all of the test they ran came out negative.tps,injectors. my bike only has 2000 miles on it and to me it doesnt make any sense.,if im in any gear and i crack it even a little bit it stalls.. can someone point me in the right direction so i can ride my bike!!! it also has a auto tune on it that when its runnin it tries tocorrect the problem and makes it worse. now i have the autotune off of the bike and the power commander is off. so pretty much the bike is stock now and it still does the same thing

Short/sweet answer? Take it to another reputable Kawi dealer.

I'm not a genius when it comes to bike maintenance, but for issues such as this, if it were a car, I'd check the fuel filter, fuel pump and everything that has anything to do with fuel delivery. I'm not entirely sure what this correlates to on the bike, but perhaps that can get you going in the right direction until someone more knowledgeable is able to answer you.

Also, check for fouled plugs and check the entire length of your throttle cable for any kinks/cracks/issues.

i checked the fuel filter all of the plugs and wires and there is still nothing found wrong with it. the dealer hooked it up to the machine and didnt find any codes. i was thinking if the tps is bad and it is not showin up on the cpu. that happened to my 2004 zx12.

Where IS the fuel filter?Any black smoke on takeoff?Can you get it to stall at your house?If you can...it will most likely code...FI error.How's starting AFTER she stalls?WHAT is your IDLE set at?And is there any throttle free play(or return play?)

there are no f i lights or anything. the bike will idle but if it idles too long the stalling gets more persistant. if i drive thru the gears real softly and slowly accelerate towards 4000 rpm and shift right before it wont stall but if i hit 4000 rpms slowly it will cut off. also it does it if im at a stop sign and i hit the throttle like normal it will stall right there, no smoke hmmm this bike is killing me!!!!!

How about a pinched line at the fuel rail or maybe under the tank.When she stalls,any smell of fuel?Do you have to pump the throttle to restart?You say it will idle...okay....how is it idling?Up and Down,or smooth and steady.What is the idle set at?Sounds like it's starving for fuel.My guess...pinched line somewhere.OR.....fuel pump going out.When you first turn the key on....does she sound like she's cycling through the fuel pump circuit okay?

the idle is smooth and it acts fine when i start it. i just took it and adjusted the throttle and it still cuts out. tomorrow i am going to take everything apart on the bike and check everything. the bike sat for all of last winter and when i took it out of storage and put the exhaust power commander and auto tune on is when it started to mess up. like i said before kawasaki hooked it up on the machine and everything came back ok but the same thing happened to my zx 12 and my friends zx14??hmmmm

Ok, so you say the problem started after you took it out of winter storage. Did you bother to start it and run it before you attached the auto-tune & power commander or did you put them on before?

Did you tell the Kawi service center this important tidbit of info? Did you take the proper precautions when preparing the bike for winter storage? Can you please explain what you did for winterizing your bike?

Well...I'd say if it wasn't properly winterized,installing that PC AUTOTUNE "could be" what's going wrong...It would have a hell of a time trying to make map adjustments if stuff was clogged up or whatever.Loaded's got a point....doing all that BEFORE starting out of storage is probably what's happening.Prolly just needs some TLC in the fuel system...start from scratch.But ya still didn't mention WHERE the fuel filter's at....???????

Hard to believe(I'm not doubting you)that she stalled or whatever while on the Kawasaki Computer,and NOTHING showed up.THAT doesn't make sense to me.No stored codes?HHHMMMMMMMmmm.

Instead of "takin her all apart",why not just get some Gumout Maximum,something strong like that.Put that in there.REMOVE the PC.Hook er back up stock.Start er and let er run there for a good half hour or so.THEN see how she does.Lot less to go wrong that way,plus you you may just find out it's nothing serious at all but some gummed up injectors...???Get the PC out of the picture.That's what I'd start at.She'll revert back to the stock map.No prob there.

I'd also be curious to know what happened with his fuel in the tank while in storage. But the gumout should resolve that I would think. I'm not experienced with codes being thrown on bikes and how reliable that process is, but I can tell you on a car, lots of things sneak by the sensors which obviously makes for difficult troubleshooting when things go awry. But yeah, go with blue on this - remember the principle suck, squeeze, bang, blow, and diagnose accordingly.

It also just sounds like this particular service center just "gave up". I'm not sure I'd go back there again. Instead, find another place, do some research and see what other customers are saying about their experience there. This is all assuming you don't have the time to commit to troubleshooting the problem yourself, of course.

i was lookin at the bike today and i reset the bike by disconnecting the power for 10 min. the auto tune and power commander is off of the bike. a friend of mine races his 14 and told me that he had to take everything off and get his tps calibrated because the autotune made it malfunction and the only way he knew that was because his race mechanic had the electrical schematics with all of the numbers and they were way off. he said that if you hook it up to a machine at kawi that it wont register as a bad tps because it works it just isnt working right. also once i reset the bike it ran perfect for a hard ride up the street without stalling then once i turned around and hit the throttle she sstalled again. as for the fuel filter and pump they were checked at a kawasaki dealer and were fine. i am in the process of adjusting the tps tomorrow morning as i am drained today cause the bike is a pain in the ass to diagnose and take apart!!!!i will let yall know what i find out

Is your bike under warranty?If so,messing with the TPS is gonna void your warranty(at least for service to that part).Proceed at yer own risk....Kawi strictly says....DON'T mess with the TPS.("there is no adjustment").You're talking about the throttle sensors,yes?The two on the right side at the throttle bodies?I wouldn't mess with those if it were me.Course,if you can do it...go for it.

You said she ran great "up the street",but acted up on the way back.So she DID correct at least once.Did you put any Gumout in the fuel?Anything like that?

Fuel filter lol there isn't one there is just a fine mesh screen in the tank believe it or not. Ok what yr is she it seams that the early bikes had problems with the fuel pumps they work just not right. Keep up the post so we can see what it ends up being I know a few guys have had to replace the ecu just to get things right theese bikes are so sensetive to changes in some cases where as in other cases they seam like they never have had a problem (I 'll just add my 07 has no filter) but I think none of them do.As well you might ask your buddy what the numbers are on new injecters if he knows then you can check them as well with an ohm meter to see if you have a problem there they do go bad good luck you'll find the problem.

i am doing the plugs agian since they were supposed to be done and they werent. i fixed the throttle problem it was the tps and it is ok now. they are checking the strainer too . when the bike is cold she runs fine but when i stay in a gear for too long then it will bog out. i still dont have full power tho.???hmmmmm any thoughts???

Kinda was what I was getting at...in a roundabout way.The fuel pump IS the fuel filter.So when he said he changed the filter....hhmmmm....I was curious as to WHAT he actually DID change.Maybe something NOT supposed to be messed with?LOL!I'm wondering now....HOW did you get the TPS adjusted?It's a NO NO in the manual.At least yer getting close to getting yer baby running correctly!Glad for ya there!!

"when I stay in a gear for TOO LONG...it'll bog"...not sure what that means.You mean...she begins to bog at the given rpm in that gear in cruising mode?You begin losing power without doing anything with the throttle?Is your engine having (seconds) of MORE POWER while cruising?Without changing the throttle input?Basically surging at all?

hi,any update on the story?

my zx14 2008 now also having a same problem,change a new ecu and tps also no help...

finaly find out what my problem is.
it was the fuel pump filter dirty making the fuel supply low when accelerate hard after running a while.
yesterday after open the fuel pump and clean the filter,
the problem solve.
forgive me if my english poor.

1400 - thanks for posting this info. Can you tell me how you did this and perhaps include pictures if you have any? I feel like this is something that will turn out to be fairly common.

here are the site i find out how to save the fuel pump

i don't know how to open it, cause my mechanic fix it for me when i let him view this site

http://kawasakiworld.com/zx-12r/38242-low-fuel-pump-pressure-zx12-zx14.html

hope this can help.

My car was like yours, and that the sensor 2-hour scooter and unstable operation PTS expect people to help me. My English is poor so I sympathize, thank you.

2008 ZX-14 surging and bucking when I accelerate. When I WOT it starts jumping like missing fuel or something. This guy in another site had these problems as well and he wrote the following…………….. After thinking it was mapping issues and a trip to the dyno proved otherwise and the guy said I had fueling issues and that the bike won’t take fuel over 20% throttle, I found some info on how common it was for the fuel pump filter to get clogged which causes the same symptoms I was experiencing (no fuel, lean feeling conditions)
long story short the guy put injectors and a new pump and the same symptoms where going on. My bike is stock and was running fine. I went to work on it and when it was time to leave at the end of the day it kept dyeing on me when I was trying to take off. I had to hold the clutch and rev it to be able to take off. I took the fuel pump off and checked it all over and didn’t see no filter. I changed to a new fuel hose and was going to take the injectors out so I can clean them with the fuel bar. But after this guy saying that none of these symptoms help I’m at a haul. Just trying to get some input if anyone has gone through this. The guy that had these symptoms has not replied back, so Help Please. Thanks

jar,

This may be two different variables. Keep your problems specific to your bike. Ready?

1. When did it start?
2. How many miles?
3. Are you the orgy owner?
4. What mods if any tiny to whatever?
5. What was the last thing you did to the bike it started up with?
6. Sit one the bike, go thru every step from turning the key on, what do the volts read?
7. Now start it. Where are the volts now it sits there idling?
8. When was the last service and did you follow book we are over 7,500 miles/12,000 miles, etc.?

if the bike was running ok when you parked it
my guess is the PC auto tune that you installed is the problem!

The issue described sounds a lot like a fuel filter issue. This is extremely common on the zx-14. 08 and newer models have a serviceable filter despite what Kawasaki's attempt to milk you for $300 on a new assembly. 08 and newer assemblies use Kawasaki filter number 49019-0013. This filter is cataloged for a Brute 49019-0013 4-wheeler but it fits the ZX-14 perfectly.Give it a shot, $13 on ebay $30 at the dealer. Either way it's better than buying a new assembly. My bike runs like a champ now!
