dies when pulling the clutch ***FIXED. PG 2***

I posted this on another forum a few days ago and just copied and pasted it over here. so the timelines are off a tad. LOL


Hi. New guy here. Well I've always told myself i would NEVER buy a new vehicle, and here i let the wife talk me into getting a new ninja last year. And here I am. screwing the warranty after having been told by the dealer that they won't do anything because "the bike is fine and it's normal". I'll just stick to working on my own rigs.



So i'm hoping you guys can help me figure this one out. cuz i'm out of ideas.

2007 Ninja 250, 4,000 miles NO MODS.


about a month ago, it nearly overnight developed this really odd problem that has been getting worse and worse to the point that my wife can duplicate it on command like clockwork.

on a cold start (first time in the morning, or after the bike has sat for a couple hours) when she takes off for the first 1/4-1/2miles, the bike will run fine, but when she is coming to a stop and goes to pull in the clutch lever in, the bike will die. sometimes it takes several attempts to get it to restart. it will do that several times. generally on our "test runs" she can get it to do it at least 2-3x. once you get going though, and the bike gets just a tad warmer, then it won't do it anymore.

and on really cold cold starts, you pull the choke, start the bike, let it warm up, turn the choke off and it dies. then it takes several (up to about 10) tries just to get it started again.

Now the i have personally been able to duplicate the problem. my wife went to the dealer every day for a week while they kept it there to work on it, and every day duplicated the problem with 2 service writers and techs watching. they even got on their own bikes and followed her down the road and watched the bike die. so they obviously saw it happen. one of their own guys was able to make it happen. but only 1x.


the only thing the dealer did was clean the carbs (which they said looked 100% clean, but they just did it anyways), found the atmospheric pressure vent pinched off, so they fixed that and aired up the tires. they called us and told us the bike was fine and wasn't dying anymore. but within 5 minutes of us getting there, the wife duplicated the choke dying and the clutch dying at least 4x.



well today they told us that since their techs can't find a problem and can't duplicate it, that there is nothing with the bike and that they will not work on it anymore.



any ideas where i should start. cuz i've been sitting next to this bike for the last couple hours racking my head with ideas, and i honestly have no idea where to start. i have taken it on test rides to see if i can notice anything that may be unrelated to the clutch that might be killing it, but only does it for the first 1/4-1/2mile after a cold start, and only when pulling in the clutch to coast/stop. clutch/shift is fine. only when you pull the clutch and let it coast or to brake does it die.


Thanks.

Try adjusting the free play on the clutch lever. It may be out of adjustment.

wondering if your altitude has an affect, what are the rpms when you have choke on? Can you possibly leave the choke on to keep the rpm's around 1.3-1.5k and ride it like that to see if it stops the engine from dying when pulling in the clutch to stop. If it doesnt maybe the bikes not getting the air/fuel it needs...

The only thing else that I can think off is to pull the spark plugs and check there condition and replacethem if required. Also try runing some sea foam cleaner thru the gas tank. If all that checks out good then try looking into the nuetral kill switch. I hope this helps.

Just had a thought: before doing what's below, completely drain and re-fill the gas tank with fresh gas, and drain the float bowls into a clean cup. Inspect the cup for signs of particulates. Double check air filter and potential for airbox obstruction. To rule out tank vacuum issue, ride with the gas cap loose one day.

Just had another thought: before doing what's below, make sure the choke cable is adjusted so that when the lever is all the way forward (no choke) there is a little bit of slack in the cable.

--------------
You need to pull the carbs again, and do it yourself this time. The FAQ at Ninja250.org should be able to help in this regard. Here's what you need to check:

Pilot jets (the sunken-in ones): Make sure you can see through the side holes, spray some carb cleaner through the body orifice, follow with COPPER wire and more carb cleaner

Floats: Set the float height to 17mm, insure the piston moves freely and that the seats are clean

Now, I don't expect those to be a problem. While you're in there, throw a #4 washer underneath the needles.

Next, close the carbs back up and pull the EPA plugs that cover the mixture screws. Easiest way to do this is to put the carbs in a vice on your drill press, drill a 1/8" hole no more than 3/16" deep and thread in a self-tapping machine screw. Then grab the screw with some vice grips and pull the plug out.

Once you have the caps off, turn the mixture screws all the way in -- count how many turns. If it was less than 2.75 or more than 4, reset set them 2.75. Otherwise put them back where they were.

Reassemble. Pay close attention that you get a good seal against the airbox. It's a bitch.

my first thought was the gas as well - since you said she hadn't ridden in a year because of the baby, how was it wintered? did you store it with gas in it? have you filled up lately? perhaps completely draining the tank and putting fresh gas in will help fix the problem?

tried that already too, and doesn't matter. even with choke on, it will intermittently die. sometimes it dies just by turning the choke off after letting it warm up, and then it won't restart. so it dies either way.

have to check the plugs yet. already ran seafoam through (i don't use anything else. but seafoam rocks.) and ran the hell out of the bike just to make sure it didn't need to just wake up.

i was going to try and temporarily bypass/disable the clutch switch at the clutch lever, and the kickstand switch to see if that would change anything. but i don't have the service manual yet, and without a wiring diagram i don't wanna go messing with that.

Wes

the bike gets a full fresh tank of gas roughly every 2-3 days.

i didn't check the bowls or the carbs yet myself this year since as i mentioned, the dealer says they pulled the carbs apart and cleaned them (even though i told them that wasn't the problem, and since it's still doing exactly what it was before, i guess i was right). so i would assume that for now it's clean.

i did pull that little joke of a fuel filter out of the tube going to the carb yesterday, and it was clean.

air filter seems to be good.

already tried riding with the gas cap open. no change. still dies.

i checked the choke slide and cable couple days ago. seemed to be adjusted perfectly. with just a hair of slack in the cable, and a small gap before the bracket engages the needle to start sliding it.

the plug on the air/fuel mixture screw is already removed. the dealer said they removed it and turned the mixture up just a hair richer because they said it was running to lean. (which i believe to be true after some extensive research yesterday, i discovered that excessive blueing of pipes is caused by lean condition, and gold is running normal-rich. well her headers are completely blue all the way down past the lower bends under the bike.



the part that is throwing me off is the fact that the problem started practically overnight without anything having been done to the bike at all. one day it was fine, and the next day it started stalling and getting progressively worse.



for some reason i keep thinking that it's either an intermittent electrical issue in the clutch/kickstand circuit, and that's why it only does it with the clutch pulled. but if it was an electrical issue, then i would assume it would do it all the time, not just on cold starts.

i also keep thinking that it's almost acting as though it was running just barely rich enough that it's actually flooding it until it gets up to temp. but not real sure about that either.

Having followed your original thread, and now this duplicate, something finally clicked in my head....

It's dying when she pulls in the clutch, which in and of itself, should not kill the engine, since all it's doing is taking the load off. So I got to thinking - what else is happening at the same time?

Is it when she pulls in the clutch to up-shift that it dies? When she pulls it in to down-shift, or when she pulls it in to idle at an intersection?

If it's while pulling it in to idle, it may be a simple matter of idle adjustment. The quick way to check this is to have her try keeping a small amount of throttle open when she stops and idles. If that fixes it, then it's just a matter of turning the idle adjust screw (which does the same thing as giving it a little bit of throttle.

On my Virago, if I adjust my idle setting to idle at 1,100 rpm after the bike's been warmed up 10 minutes or so, it will do great, and idle smooth - unless I ride for more than an hour on a hot day, and then it will die when I come to an intersection and pull in the clutch. It's not dying because the clutch got pulled in though, it's dying because the idle adjust isn't proper for those conditions. After the engine is hot (or fully warmed, or whatever) if I then adjust it for an 1,100 rpm idle, it will be fine, but on shorter rides, it will be idling around 2K. I assume it's just an issue of jet expansion/contraction due to heating.

sounds like a somewhat decent explanation. has nothing to do with "quick" clutch pulls. upshift, downshift, etc... is fine. it only happens when you hold the clutch for extended time.

"generally" you only hold the clutch for extended time is when you are slowing to come to a stop. so for the longest time we would word it "stalls when coming to a stop".

then while diagnosing it, i asked her if it also does it just riding, so she tried it, and discovered that she can often times duplicate the stalling issue by simply pulling in the clutch (no throttle) no matter what gear, mph, or RPM.


i did adjust the Idle up yesterday just a tad bit, but as you said i noticed that if it wasn't "fully" warmed up yet, then it would be where i adjusted it to. but then after riding it, it would be a tad off from where i set it, etc..etc..etc..


well from reading this forum, it seems that most of you guys seem to be happy with your little 250's. so hopefully i can figure out this problem soon, so the wife can ride it a little safer and enjoy it better. cuz the last few days i've been getting very upset that we went to buy a bike and bought a toy instead. i was starting to wonder if "that's what i get for buying a toy".


oh and no more new bikes. no point in paying extra for warranty, service plans, etc... when i end up having to wrench on it myself like i told the wife would happen. oh well...........live and learn right.

sounds to me like the pilot jet is clogged or the idle adjustment is so out of whack, after it warms up, it's not getting enough gas.

if you think it an electrical issue, bypass the clutch switch as you have planned.

and personally, if it's under warranty, I'd be back at the dealer to make them fix the problem. mention something about "lemon law" and see if they don't help you a bit more... or find another dealer.

I'm with kkim thinking it's a pilot circuit problem.

I never trust dealers to fully/completely clean carburetors.

It sounds to me like the pilot mixture is too lean. This can happen with poor adjustment (and they are all poorly adjusted from the factory), extreme mild clogging in the pilot jet (slow jet), or a combination of both.

I can virtually guarantee it's not an electrical problem of any sort. That includes plugs.

.

the problem is NOT after it warms up. it's on cold start (regardless if first start of the day, or after a couple hours of sitting). after the first 1/2-1mile, it seems to be fine.

are you leaving the choke on for that first 1/2-1 mile?

what rpm does your bike idle at after it's fully warmed up?

scorpio_vette: Recall that you need more fuel in the small-throttle-opening range when the engine is cold than when it is hot. This is because the fuel can condensate and cool the intake tract, head, and cylinder wall before the spark tries to ignite it. That is why we have a fuel enrichment circut, and why the engine is more sensitive to pilot circuit tuning when it is cold.

no we are not. i did try it for "testing purposes", and it still died.


no please bare with me, and don't take this as in me trying to argue. i'm just trying to learn and understand and look at it from all angles.


when we first purchased the bike and rode it last year, we only had to use the choke for approximately 30seconds-1minute, and the bike was ready to roll. never had any issues. this year it started fine after sitting over winter (winterized), and started/ran fine with only having to choke it for less than 1minute, and it was ready to go. this whole dying issue started practically over night, and was only occasional for the first couple of days, and then over a matter of days got so bad that now it does it on every cold start guaranteed like clockwork.

so how would the bike go from being fine one day, to suddenly have a bad jet, etc..... over night???



now i will be pulling out the carbs here very soon (as soon as time permits. a little harder now that i gotta watch our little 5month old all day. LOL) just to make sure. does anybody have a writeup specific to these little ninja carbs, just to make sure i don't overlook anything???




sorry for all these questions and back and forth. i know it really sucks, but i just seem to be really stuck on what and/or how the bike could have went to crap overnight. usually from my experience, when parts go bad over night, they have to be functional/moving parts, such as fuel injectors, electrical, water pumps, etc... but a carb jet is nothing more than a hollow "tube" of varies sizing (depending on the jetting) correct??? so for a jet to go bad overnight, you'd have to get something stuck in one, or get some really really really really messed up gas. correct???



the RPM was originally set to 1,200-1,300 (i think), and always held steady after warmup. yesterday night i turned it to approximately 1,500 after warmup to see if that would make a difference, but the wife got home today and set the bike still died on her.

scorpio,

I've not taken your replies as arguments... in fact your last post really cleared up a lot of things. troubleshooting over the internet is not an easy task, so if I ask questions that sound dumb or give recommendations that are flat out wrong, it's because of not being there to witness firsthand.

it does sound like you have some dirt stuck in in the carbs. Taking them apart and cleaning them would be a good idea at this point.

do you happen to know what the mixture screws are set at now?

do you have a service manual?

This has actually happened to me a couple of times right after I got my bike. What my dealer found was that the setscrew from the idle was messed up. It would move on it's own just from regular engine vibration. That was throwing my idle completely off and making a cold start dang near impossible. It would die on my constantly, especially when pulling the clutch in. Not saying it'll fix it, but check your idle screw just to be sure that it's not only in the right position, but not moving without your permission. That's all I can think of, and it probably won't help, but that's what I get for being a sad excuse for a mechanic! Hope it helps and if not that you figure out your problem!

no. it ONLY does it on cold starts (regardless if it's the first start of the day, or after the bike has been sitting a couple hours). it does it roughly within the first 1/2-1mile after cold start.

just for testing, i even had the wife start the bike, and let it warm up for 5minutes exactly (i timed it with a watch), and then take it for a test ride. it still died. but after the first 1/2-1mile AFTER A COLD START, then it works just fine.


that is why we can duplicate so perfectly on command. all we have to do is wait for the bike to cool down, and we can do it every single time.




unfortunately i will not be able to work on the bike for a while now as i herniated a disc in my neck last night and have very limited mobility right now. so i guess i have alot of time to do some more research and get ready to work on the bike once i get better. LOL


i currently do not have a service manual, but will be ordering the set here shortly.

You know, this is a classic pilot circuit issue. You really need to look at your carbs. If you had the EPA caps off, a half twist would probably fix it right up.

well since i can't move for a while, i was able to get my hands on the service manual last night. so i got some good reading material to pass the time. LOL


the EPA cap(s) are the little plugs that go over the air/fuel mixture screws on the bottom of the carbs right??? the dealer claimed that they removed them and turned the air/fuel mixture a tad bit richer. but i'll check that too when i end up pulling the carbs after i get better.

ok so i read the service manual today, and so far only 1 thing seemed to really catch my attention.

"coasting enricher system"


now i believe i understand how the "choke" or enricher circuit on the 250 works, BUT

when i tried to google "coasting enricher system", i seemed to find some information that a "coasting enricher system" actually supplies fuel at certain times while the clutch is pulled and coasting due to differences in vacuum or something. (sorry i read way to fricking much about bike carbs and engines again today that i'm at the point of a headache and very very confused. so i have to let this all sink in for a day and then go and re-read it all again. LOL)



anyways, does the enricher system on the 250 have some type of "auto supply" or something that might not be working on my bike when it's cold, and therefore not keeping it running when holding the clutch???


or do our bikes ONLY use the enricher system when the "choke lever" is pulled???

Quote:
COASTING ENRICHER - Feeding a Closed Mouth
You're blasting down the road and you see a hairpin coming up, so you close the throttle. This closes the butterfly valve. You and your 400 lb. baby (the bike, not the other love of your life), are still rolling with inertia, keeping the engine revs high. Now it can't get the mixture it's trying to suck in because the butterfly valve is closed, blocking the air flow.



To compensate for this there's an air jet in the lower diaphragm chamber that transfers ambient pressure to one side of the coasting enricher's spring-loaded cut off valve. The excess vacuum in front of the butterfly valve is transferred to a drilling that leads to the other side of the cut off valve. This sucks it open, allowing the pilot jet to feed more fuel to the engine, preventing an overly lean condition. (Pop. Pop. Pop.)
sounds like it controls. so could it be possible that something with this part, circuit or whatever you want to call it might be bad???

any explanation why it only does it on COLD STARTS, but after it warms up it's fine???

maybe it's only partially blocked (some dirt in the enrichener drilling)? On cold starts, you need more fuel than a warm start.

any suggestions on how to make sure that i 100% "bore" out all the ports, jets and passages??? obviously i don't want to use anything like wire or metalic so i don't scratch anything and cause damage.
i was thinking something like fishing line, or guitar string.


anybody have some recommendations or experience on what would work the best to make sure that they are 100% "bored" out and clean.

those small passages are a real PITA. When I clean out carbs, I usually soak them in a carb cleaning bath, then use compressed air with a rubber tipped nozzle to blow the passages clean from the opposite direction that the flow normally occurs. some spray carb cleaner might work, depending on what is blocking the passage. watch out... any carb cleaning liquid is nasty, so use a lot of rags to catch the flying droplets produced from blowing with compressed air.

sometimes you need to resort to pieces of wire to clean out the bore, though.

You can use COPPER wire on those small passages. The copper is softer than the brass and the aluminium and will not damage it.

I don't think your problem is with the coasting enrichener, normally when it's not working right you get lean-miss backfires. That said, it wouldn't hurt to look at it. It's the snail-shaped thing on the left side of the carbs.

But make sure you turn in, count, and turn out your mixture screw settings. Even if the dealer gave them a twist, they're likely to be wrong. They're almost always set too lean and unequal from the factory.

Also make sure you take the pilot jet right out of the carb. And check your float height!

i'm assuming you mean i should make sure i check the pilot jet, or do you mean something else??? your wording is confusing me a bit. sorry.

I believe he is saying to unscrew the pilot jet from the carb when you clean the parts instead of leaving them in the carb when cleaning.

kkim: Yes, thanks for the clarification. Many people seem to think leaving that jet in and soaking the carb in cleaner will get it clean. It won't.

kkim and wes seem to have this pretty well diagnosed, but my first thought was a dirty or (partially) blocked jet too. My experience with smaller bore carbuerated engines is that they are very sensitive to cold weather, so essentially even a minor carb. problem would be exacerbated by a cold start.

Just out of curiousity, when you wife pulls in the clutch when coming to a stop, has she tried blipping the throttle? Or does she just let the engine rev down to idle? Does the blipping keep the engine alive while its still warming up? This is why I like to downshift when I come to stops as opposed to just coasting in with the clutch in. Also, you don't have to completely take off the choke before you start riding. If I am in a hurry I will leave the choke maybe 1/4 on when I take off, and a couple minutes later switch it off while I'm on the road. If you could upload a video of this it would be a zillion times easier to diagnose lol.

yes she has tried holding the throttle, and believes that the couples times that she tried that it seemed to work, but she only tried it a couple times.

as i mentioned earlier, it has died BOTH with and without choke. that's one of the things that keeps seeming to confuse me, because i would figure that if it did NOT die with the choke, that it would make more sense that it was a fuel delivery issue since the choke would be supplying it. but since it also dies with the choke on, that just doesn't make sense to me.

then again it sometimes will also die when you turn the choke off. like instantly. almost like the choke is a kill switch.







anyways, for right now, i think i'm going to wait until my neck is healed well enough for me to work again, then i'm going to pull the carbs out, take them apart, clean them, adjust them, balance them, etc...etc..etc.. and then report back. and if it still does it after that, then we can keep tossing around more ideas. LOL


thanks for all your help guys. now i just hope it doesn't take to long for me to heal up. doc says up to 8 weeks. and that's the GOOD SCENARIO. if it gets worse, and i have to get an MRI, then that means there is a good chance that i'll need surgery. man i'm to young at 27 to need neck surgery. and here i always thought i'd die on my bike, not in the bedroom. LOL

I've always hoped I'd die in the bedroom.

Sounds like you guys are narrowing it down.. Hope you get better and you get your bike fixed. Interesting issue though.
