this one is plain WEIRD ! it can't do that !

[Bob KellyIII]

ok I put the new petcock on the ninja.... but I could not get gas to flow out of it.... no matter what I did ... so i drained the tank again and put the old petcock on that I had taken apart and cleaned real good and found a bit of corrosion on the sealing flange for the "o" ring to seat on so i got it cleaned up as best as I could..... it seals fairly good now so it shouldn't leak ...I hope...
put it back on the tank and added gasoline and no gas flow in any position !
i took off the lines, thinking it might be vapor locked but no flow at all !
i even opened the gas cap..... no gas flow....
now from all I know if you have a valve opening into the bottom of the
gas tank and you open that valve you should see gas flowing..... well in this case with 2 different valves no gas is flowing at all.... not even a drip.....
I've been trying to reason this out for 2 days now and according to all I know
it can't do that !!!!
.....
anybody got any ideas before I pull the tank off again and pull off the old petcock ?
.....
Remember i just pulled a bunch of the Kreem gas tank liner out of the tank with needle nose plyers and I think I got about 80 to 90% of all of it out....
no doubt there is still some in there but that should be filtered out with the many filters on the bike..... but WTF ? why no gas flow it can't do that !
.....

The original one should be vacuum operated... is there a vacuum port?

"now from all I know if you have a valve opening into the bottom of the

agreed, provided the engine is cranking/running, providing vacuum thus activating the internal diaphragm to allow fuel flow.
So, you failed to post whether the engine was actually running, or not.

[Bob KellyIII]

on PRI the gas is supposed to go straight through the petcock right ?
on... ON the engine needs to give it vacuum to open the petcock for gas to flow.... ( that's my understanding of vacuum operated petcocks)
ON PRI on both petcocks no gas flows at all....
with it on ON and the vacuum line on and cranking no gas flows on either petcock......
I haven't tested to see if I have vacuum out of that line yet when cranking it over..... but I ran the carbs completely dry and they need gas before it will run again.....
it was working great, now after trying a new petcock it don't work .... i put the old one back on and still no gas.... very weird !

just repaired a dripping petcock on an EX500 (NO prime setting), bike in my possession.

Before/after/in process pics and a vid of it running, now drip free.

Your mesh inlet filters are clear, free to flow?

[DannoXYZ]

You might have a tent of piled up peeling Kreem wrapped around outlet of tank.

Turn tank upside down. Remove petcock completely. Gradually turn tank upright.
Do you have tonne of flow?

[Bob KellyIII]

As far as I could tell there are no tents or bubbles of that stuff in there any more I got a bunch of it out of there..... when I had the tank on the bench I could see light reflecting off the top of the tank looking in the hole where the petcock goes..... yet still no flow..... which is confusing as heck I will pull the tank again and pull off the original petcock and test by blowing on it to see if air get's through it ... i bet it doesn't ! and if that's the case I will pull the valve itself apart and check it out.... i had it apart after I first got the bike and it was fine it was the diaphragm that was leaking around the "O" ring on that plug thing.
..........
I can't think of a reason besides the valve itself being plugged for it not to work
perhaps the rubber slid out of alignment and covered the hole .... that would do it because I moved the valve several times..... I bet that's it !
i'll let ya know tomorrow ! LOL
....
thanks for the help guys !
Bob.....

Turn the valve to ON and suck on the vacuum line. That is the quickest way to see if the valve is clogged. It's not like you're going to get a mouthful of fuel... maybe some fumes but that's happened enough throughout the years anyway, eh?

[Bob KellyIII]

finding a hose that size is next to impossible without a run to the parts house!
any one know the fuel inlet size, and the vacuum line size, by chance ?
.... I need to get some of that size line and have it on hand.....
.....
Bob....

[ducatiman]

perhaps take the currently non-used petcock with you to the auto parts store for fitting each?

[thedrewski86]

Don't you have that vacuum hose on the current valve? Just unplug it from the carbs.
If you don't, that's why it's not working. No vacuum hose... no vacuum.

[Bob KellyIII]

well, even though I bought a petcock for the 2012 Ninja what I got had different sized fuel outlet and vacuum line connectors ... I had to jerry rig a section to make it work just to connect to the silly thing.... i'm not all that impressed with the new petcock so I am going to try and use the old one now I think i got it sealing up good now so it should work fine....I guess I should have tried for an OEM petcock but at close to $100 bucks I felt cheap and got one for $30 bucks instead..... but i didn't figure it would have the wrong fuel line sized outlets on it... and in a different direction ! and the lines are too short to be used that way..... so it's back to the original one anyway...
....
I'll go out there and pull the original off and take apart the valve and I bet you i will find that the rubber has slipped.... I will probably crazy glue it in place so it won't slip again and then re assemble the thing
....that's the plan for today anyway.... an easy task lets see if this old man can get it done ! HAHAHAHAH
....
Bob........

[Bob KellyIII]

Yah Drew I have the original valve on it now with the vacuum line all hooked up
but still no fuel flow.... it's gott'a be the rubber in the valve itself has moved and is covering the hole so it can't flow in any form the way it is ( and it isn't)
so I'll take the valve apart and see what is what with it....
.... if it's plugged I'll un plug it, of the rubber has turned I'll correct that and glue it in place so it can't turn again...

[Bob KellyIII]

thanks Danno...... but I got it.... it dawned on me I had the 3 vacuum lines off the front of the tank just open to air...and I was wondering why it didn't work.... it's like DUH ! so I put them on and cranked it over and got a trickle of gas..... so I cranked it a bunch ...let it cool down a bit, cranked it some more
let it cool down, etc about 4 times and then it finally fired up... which gave it much more vacuum and it started flowing gas like it should !
..... I also added a bit of dot 3 brake fluid to the front reservoir while I was at it
as it was down a bit.....
turned it off and then let it set a few minutes and then tried it again and it fired right up like it is supposed to ! so that problem is solved
silly vacuum petcocks ! i did take it apart and there was nothing wrong with it.... but I had to point the gas tank up to get any gas to flow out of the tank
and there is about a gallon in the tank already ....so I added more gas and put it back on the bike ! with the rear wheel held up on the rear stand the bike is tilted nose down so there wasn't enough in the tank to come out I guess ! like DUH again !
so anyway i got it working fine now .... and the petcock does actually shut off the gas flow when the engine is not running now,.... it didn't before now it does so that is a victory !
.... thanks for the help guys !
Bob.......

[Bob KellyIII]

now I get to put the fairings back on and polish the girl up she's ready to go again.
....
Bob...

[Bob KellyIII]

I'm going to put on the rear rack that I bought too while I have it in the shop...
I haven't done that yet.... and I think the top box off the RX4 will fit on there perfectly so that the Ninja can be used to run to the store as well as the RX4...
.....
we had a mishap here last night I didn't get in on it, but the water hose from the washing machine just snapped off at the fitting and water filled the laundry room ... My Kid caught it thank good ness ! turned off the water before it flooded the entire house.... i picked up 2 new hoses and replaced both of them with new ones and fixed the problem..... but that was totally unexpected !
....
Bob....

[Bob KellyIII]

SO.... I still have questions on this original petcock.....
it has no lever ...you have to use a screwdriver to turn the valve on it....
it has ON and PRI on the face of the petcock and I think there is no reserve on it..... just the two but I may be mistaken there I'm going by memory...lol
so the ON position means gas will flow when there is vacuum present at the diaphragm..... CORRECT ?
and PRI should flow gas without vacuum present is that correct ?
.....
from what I discovered it looks like both positions need vacuum to make gas flow...... and that makes no sense to me ! why would they do that ?
there is no way to fill the carbs then if you run out of gas and then re fill it.
and that makes no sense to me at all you'ed kill the battery cranking it that long !
....
can someone please set me straight on this ?
thank you
LOL.....
Bob.....

[slowandlow]

Pri requires no vacuum to flow fuel
On requires vacuum to flow fuel

[Bob KellyIII]

thank you very much !

Your petcock is busted. Time for rebuild.

[Bob KellyIII]

I did Danno it's working great now... especially sense I hooked up ALL the vacuum lines ( I had the ones on the side of the tank off during all this like a DUMMY) ..... like duh of course the vacuum petcock wont work... theirs no vacuum with those lines off !
...
I took the petcock off and disassembled every part of it and cleaned everything
and found out why it was leaking too, the little o ring on the diaphragm metal shut-off plunger had some corrosion on it, so I got it all cleaned up and now it doesn't leak.
so it's good to go !
...
Bob....

[DannoXYZ]

except it doesn't flow in PRI position. Some passage is clogged or seal is twisted and blocking port.

[Bob KellyIII]

I think it did actually I had the rear wheel up on the home made stand I made and it puts the ass about 6" off the ground..so it tilts the gas tank a long way...
and I only had about a gallon of gas in it... when I discovered that I added about 2 more gallons to it and that petcock worked great just like it should....
....it was 2 or 3 days of Man I shouldn't be working on anything the brain ain't working ! LOL
.... and I quit taking those darn pills too ! something that simple causing me that much trouble something is messing with me ! so i said that's enough !
i ain't taking those things any more ! .... ain't had that problem sense but then it has been raining too ! HAHAHHAHAHAHA
ah well you know Doctors and their Pills ! the "magic pill society" we have a pill that will cure that ! but they don't tell you what the side effects are !
.... I've gotten so paranoid at what the doctor says now he just shakes his head ! I asked him last time I saw him that is this pill going to make my liver start eating itself ? he said WHAT ? i repeated the question and he laughed and then started telling me all the things it could do ...and I then asked him and you want me to take these things uh ? .....
ahhh well the trials and tribulations of getting old..... don't do it !
....
Bob...

[DannoXYZ]

hey, don't knock pills they aren't bad...
I used to manage Lab Info Systems at Gilead Sciences...
Pills aren't bad, they just do what they do...
If you're having bad reactions and/or not having proper effects...
It's not pill's fault, they aren't bad...
Doctor gave you wrong pills, should try some different ones..
Pills are aren't bad, they're actually good...
Perhaps try different doctor... current one may not be that good...
Pills are good....
we like pills...

[thedrewski86]

Wow, we aren't talking about fuel valves any more, are we?
I'm afraid I agree with Bob on this one... these western doctors are the new pushermen and they're killing our prophets. Listen to Black Thought. They already took Prince and Tom Petty and those guys told the truth.

When it comes to knocking someone off there are a zillion ways to do it.
and if you make enough noise someone will want to shut you up...
the Men in black are real but they work for the oil companies
Doctors use pills to do their evil work
bankers call in the special team and you'll just die of natural causes
the government uses all methods including industrial accidents and random shootings ...
the fact that special teams are available to anyone with the money to pay and the right connections, makes voicing disagreement a dangerous proposition
...scream long enough and hard enough about anything you don't like and it's libel to be a shortened endeavor !..... we don't have just one to worry about guys every big business has hit men in their pocket ! they would never admit it but that is just how America works now. if that is not bad enough "progress" is now being treated as something undesirable by certain big companies with the power to do the above and they are successfully
stopping "Progress" too ! this has been going on for Decades.... the oil companies have tried very hard to stop HHO education and development among other things, and the power companies have been fervently haulting free energy development as well
this country is ran by big business and the government pirty much gives them free reign... "pay your small taxes and keep a low profile and we'll get along just fine"
..... the moral of this story is if you develop some ground braking invention that makes free energy do not tell anyone ! or make alot of noise about it as you will dissapear quickly. the only way to get the word out is by the interned and your hopes of getting it out there are very slim as they have very good people searching for that kind of thing 24/7 ...
.....
what the future holds for humanity is totally unclear but with this sinerio it doesn't look good at all.

a suit case sized generator that developed 35kw that needed no fuel at all
was developed and was marketed for a short time like 2 or 3 days
then all of a sudden it disappeared no word from the developer or company or his financiers every one has been silent... i know what happened there...
the power companies discovered it and shut him down with death threats
or worse....
.... anyone remember the Pogue Carburetor ? same setup but a nastier outcome his 2nd attempt got him killed his shop destroyed and everyone forgot real quick about it.... that was a carburetor that would give over 150mpg on a big V-8 engine.... government ? no, just the oil companies !
.....
it's a mean world we live in and you should keep your voices low !
