2007 Ninja 250 question

[drdriftking007]

Ok guys need your help please! So i pumped gas last night...and i was driving home i came to a stop and my rpm starts going off and shuts off. I put the choke lever all the way down and turn the bike on again and it turns on for like 2 seconds and shuts off...in order to keep the bike on i have to rev the rpm a bit high. Anyone know whats wrong? Everything was fine with the bike...never had problems.

Has the bike been sitting for a least a month with gas in the carbs? If so, it is probably just old gas causing it to not run smoothly.

Mine did this while it sat in the garage for about a month. I didn't drain the carbs so I believe it was just old gas that had moisture in it. I just added Berryman B12 to the gas and shook it around and ran it until the bike could idle without dying. http://shop.advanceautoparts.com/web..._T|GRP2030C___

Maybe that is your problem or maybe your carbs could use some cleaning. But probably not if it was running fine earlier.

Drain the bowls and look for water in the fuel.

If you find water, then, you need to drain the tank.

It may be also a vacuum leak preventing the valve from opening the flow of gas into the carbs.

[csmith12]

Check your air filter and box, clogged or any debris in there?
Petcock partially on or between settings?
Maybe just a bad tank of gas... it happens. Flush and fill with gas from another station.

Was you running really low and had it set it to "res"? Maybe a bit of debris got caught up in a jet.

Good luck!

So i add that berryman b12 to new gas and thats it?

Yeah. it tells you how much to put in the tank. I think it is only a couple ounces. I don't remember. Then just close the cap and shake the bike around. And start it up and let it run.

Also check the vacuum lines and such little others have mentioned. Removing the carbs is like a last resort.

Awesome! Ill buy that today then!


NOOB Question...which vacuum lines are you talking about? lol sorry

[Jono]

There are two hoses connected to the petcock on the gas tank. The smaller hose is the vacuum hose. Make sure it is nice and secure then follow it to the carbs and check and make sure it is tight to where it connects to the carbs.

I doubt it is a vacuum problem but it is any easy check.

Ok Jon thanks so much! & all other forum buddies

[Motofool]

Report back, please

[drdriftking007]

I sure will! I should do this at 7pm central time and will post details

[drdriftking007]

Alright guys so I saw the BIG problem...just got home and noticed a smell of gas. Apparently I have a small hole in my gas tank which I'm assuming is causing the bike to turn off.....man this sucks. Do I just need a new tank?

[drdriftking007]

Anything I can do?

[krolinked]

I could be wrong but, could there be a way to patch it? what caused the hole?

[Motofool]

Really sucks and is rare that a 2007 has a rusted tank.

I have heard of some epoxies that resist gas; however, the main problem is to obtain a surface that is really clean for the glue to stick.

If it is really corrosion, you may have more little holes working their way out.

I could be caused for some part rubbing against the tank.

Wow!!! So I tell my uncles (who lives next door) and he screwed on my turn signals on to the holes on the gas tanks....which I'm assuming he caused a puncture


Is there anyway to patch it?

[Motofool]

Only time I tried was with J&B weld epoxy on a diesel tank.

It worked for a few days, and then started leaking very little.

I can't tell you how well it would work with gasoline+ethanol, sorry.

[drdriftking007]

I was reading this was a recall and possible that a dealer could replace...

Ah man that really sucks your uncle tried to screw the turn signals onto the tank! I could have told you NOT to do that. That screw has to be just the perfect length or else it punctures the tank. Which you just discovered.

Since the fairing bolt wasn't the bolt that actually punctured the tank I doubt the recall will cover it. But I guess they won't know what really happened.


I think many people have accidentally made this same mistake so their should be some advice somewhere out there on the internet.


I have no answer to this one. lol
Sorry. Hopefully someone here will give you some usable advice.


I would take it to a dealer and try and claim that recall.

[drdriftking007]

Alright guys so I went to the dealership max they didn't accept the recall. I bought some job welding and it sealed the leak now my bike wont idle well. It will start out fine and them just shut off what's going on??

[TheFranchise216]

I had what could be the same issue yesterday. I was riding (my first "real road" ride) at about 50mph and when I went to slow down & downshift approaching a light, the bike just died.... I ended up having to walk it home since it happened again. To be sure, I filled up my gas can and filled up the tank at home and gas came pouring out of my right side bolt hole. So now I'm looking for the same solution and wondering whether it will fix the problem of the bike dying on the road... not very safe :-/

[Motofool]

So Eddie, do you think that the original problem was not caused by low fuel level in the tank?

If so, I first would check that fuel is reaching the carbs when the engine is off and vacuum is applied to the petcock.

In order to do that, disconnect the fuel hose from the carb nipple.
Right at that end, you should find a little mesh filter; remove it and blow thru it.

Put the end of the hose into a clean bottle and open the petcock.
If gas does not flow, apply some vacuum thru the smaller hose that connects to the petcock.

If gas still doesn't flow down, find a way to blow backwards in order to clean the mesh filters that are inside the tank, in open and reserve positions (with the tank cap open).

Close the tank cap and let gas flow long enough in order to see if it slows down, showing that the buil-in ventilation of the tank cap is not working properly.

Thanks!! How did you apply it on? Outside? I have not the slightest clue how to fix it up. Could you explain what you did? You can say no if it's too much.. haha.

Well I know a big problem was with a leak I had in my gas tank which i sealed with JB Weld...it was really good!

Now from the looks of it that hose that comes from the fuel tank is not connected towards the end and also the coolant hose. Which look below. Where do they go? never had to mess with this bike before.

[csmith12]

They connect to nothing. They are overflow/venting hoses. Route them to the ground and hidden away.

Ok, so first buy that of course! lol

Step 1. Cut a piece and start rubbing it between your hands then ( i used a hanger) and spread it towards the puncture and kind of spread it really well and also apply double coats and easy as that thats it. just spread it evenly and basically it will harden and work well.

this is where my puncture was at...

Looks good! Yea on mine you can see straight through that bolt hole. So did you apply the JB Weld from the inside of the tank via the hanger? That's the question I was trying to think of before. Sorry if it's repetitive.

It's ok I put it from the outside nothing to it you might have to cover the hole entirely with jb weld

I thought it might be a possibility to just seal the hole shut. I assume the front faring would be fine with the other bolts and the mirrors holding it down.

Yeah..should be fine

nope. The plugged short hose goes to your airbox. (idk what it does except collect oil, which I found out that mine did when I cut my battery box off my airbox) the long black one is the breather hose for the gas tank. As gas is drained by the petcock, the breather allows air into the tank to correct the negative pressure do to gas leaving the tank. If there was a negative pressure in the tank, the engine would starve. The breather is perfectly fine to just dangle down and be contained in the little metal loop that holds it steady

Wait a sec.. I don't have a breather hose coming off of the rear side of my tank. The nipple that's there is obviously covered up by the seat when it's on. Could this be at least part of the reason I'm having the issue describes in my thread (http://www.ninjette.org/forums/showthread.php?t=101127) about the bike dying while riding?

unfortunately, no.

It doesn't matter if the hose is connected to the nipple or not, air will still flow into the tank from the nipple that the breather connects to. I'm pretty sure the hose is just there in case water gets in around the gas cap lid. That way, water will drain out the breather and down the hose to the bottom of the bike, not just to the bottom of your seat.

Correct! That is not the cause of your issues.
