OMG! you guys are super amazing!!!! @DannoXYZ : you were correct with this, I found the issue. It was the hose from petcock to carb, the filter was mangled up inside blocking the flow of fuel. See my image for this. Now the bike started, it idles and revs (up to 5-6k rpm) a bit but I still need help with the rest. I can't tell you how happy I was to finally figure out the issue (with help from you all).

Now, the bike starts, idles with and without choke, stayed on for 5-6 mins.
Once the engine warmed up, I noticed the image C, green (coolant?) Liquid started following though this outlet. It was fairly warm and was dripping all over the engine. Also, image B, was spitting out large amount of steam from 1 cylinder looking thing. And then bike stalled itself, (guessing some hose routing isn't correct) . Could you please help me figure this out. I have a few connections stray and not connected at this stage: Image B, point 1 - not connected Image C, (under right carb, bottom facing outside) Top of coolant reservoir, white hose outlet, Hope this makes sense to you guys and may be you can shed some light. Thanks !

So you saying the stem outlet image B1 and C are supposed to connect via a hose? Just to reconfirm. Don't understand how that's going to work cuz they both outlets and not like one is in and other is out. But let me try to join them. Looks like the "mechanic" who took the carbs for so called "cleaning" must have forgotten to put that particular hose back on, and now it's missing (probably somewhere in his garage). FFS I'm going to have to DIY something make make it connect the two together.

So, you are going to need to order part 390620249 "hose" and pair of 921711051 "clamps" Don't go buy any old hose's keep in mind that needs be made for hot coolant That other hose? maybe fuel tank drain hose "In post 44 the white arrow" but it way to short for that it needs to be at lease a .5 meter long and only has one clamp on end which for overflow of gas and water under the gas cap to drian off . For we know he could install the wrong hose so that extra hose you have is actually for carburetor vacuum lines going to the fuel petcock being it has the rigth clamps for carb and the one that on there now at T is the ones for the coolant. |

Wooo dude ! you mean to tell me my 250R ninja has a coolant line going to the carbs ???? that is totally unexpected ! I suppose the reason for that would be to keep the carbs at a even temperature, i.e. they used to get too hot in running so they added the coolant which isn't COOL by any means but it's better than boiling the gas in the carbs ! and a side benefit of getting better gas milage from the engine would also be realised .... that coolant to the carbs would likely only pass through a horizontal hole in each carb and return to the radiator
just enough to regulate the temperature a bit sense the engine head is very hot it would likely be at the front of the carb, but sense aluminum transfers heat so well it could also be at the back of the carb.... I find that very Bazaar ! coolant line to the carbs ! who'd a' thunk it ??? LOL... I'll have to pay closer attention to my bike when I pull the carbs off but I didn't notice anything like that before... it could be only the older models have that...i dunno ! also probably why they added the carbon canister and air pollution crap on the bike as well.... one thing leads to another and it was needed ! ..... that is a new one on me ! .... thanks for the info...Anthony ! ... Bob......

oh those poor bast$#@ds have to put up with that ??? my condolences !
and I thought california was bad ! ..... that's OK california has already got laws on the books saying in a few years no one can sell gas or diesel powered vehicles of any kind..... time for a revolution I guess,lol... they didn't even put it to a vote they did it by themselves ! and they are supposed to be representing the people that live here.... .....time to fire them all ! I honestly believe the simpler the better with bikes and cars but what do we get ? more and more complex stuff that takes 2 college degrees just to understand it ! yet alone have the special tools and certificate to be legal to work on it.... Sigh! our society is seriously broken ! Bob.....

yah 1970's chevy trucks had them in a plate under the carb
to stop carb ICENG which would lead to a vapor lock ! they had PVC valves those crazy environmentalists got them to pass that one ! then they came up with smog pumps ! a total disaster that did not reduce emissions it worsened them ! but the consumer paid the price ! ... same thing with the fuel from the very start they said they had to do something as you couldn't see from all the smog in the L.A. basin... they made us use unleaded fuel and discovered that the emissions out of the cars was 10 times as bad as it ate the paint off the road signs ! but they stuck with it anyway ... after all it's not good politics to say oh we screwed up ! sorry so instead of changing back to leaded fuel we still have it and catalytic converters in every car and a ton of other crap to make up for their Oversite ! and they have the gaul to say it's for the reduction of pollution .... oh well.... no one ever said politicians are smart ! they just kiss babies and shake alot of hands and then take long vacations ! .... there's gott'a be a better way ! HAHAHAHA Bob.....

Yeah, I'm with you on wanting simpler machinery instead of the complicated *^%. Cars and bikes are getting more and more stuff on them, and it doesn't improve the user experience. It's subscription based stuff, and screens, and more *^* to break and to pay for.
Not cool. |

LOL unfortunately that's progress for ya !
the idea of Making it better is still there but the "what can we add on there so we can raise the price to make more money" has virtually taken over ! from TV's and CD players in the back seats to automatic parallel parking systems it's all just to separate you from your money ! .... when I was a kid I was appalled at how much a used motorcycle costs at half or a little less than half of a brand new one. so I got basket cases and put them together and made them work that was the cheap way to go back in those days ... now you cannot find basket cases..... guys buy them up and sell the parts on e-bay... .... the motorcycle itself is the the main part but it only costs around $2000~$3000 to make a 750cc bike however they charge $10,000 plus for that bike off the show room floor. you are paying dearly for all the extra stuff that they put on there ! .... and it's the same for cars you do not get anything anymore at COST to make it .... it is all marked up...that was not always the case. .... consider this.... I can make bird houses and sell them... it cost me $4.00 for material each.... and I sell them for 100% profit at $8.00 each that should be enough profit you'd think right ? ...that's a good money maker at 100% profit ! but no... you see the same bird houses in stores for $29.95.... how can you justify a price like that ?..... it's what ever the market will bare.! and it's not any longer what the thing is worth it's how much can they get from you for it Housing has been like that for a hundred years now....everything else has just caught up is all... .... Bob......

We never have problems with water-cooling system... many benefits with zero downsides...
However, most issues are due to carbs... There's new BSA.... .. luckily, future versions will be ELECTRIC!!! |

yes the future is electric because the government demands it... you won't be able to buy a gas powered bike in a few short years !
but the problem is the electric is not ready yet .. they have very short range and no charging infrastructure ...people in the rural areas are going to be screwed when they have to drive 45 miles one way and have to re charge to make it home..... not to mention recharging is going to cost you alot more than a tank of gas would even now, at these high gas prices..... electric is not ready. nore is the pocket book ! on the best of terms you could charge it at home in 8 hrs .... but what about shipping ? you NEED big diesel trucks to do that not some wimpy electric mini truck like Tesla is so proud of ... and to have the state pass a law that says no gas powered vehicles will be sold after a certain date is plane stupid... god help us ! ..... Bob....

That's what they said about gasoline engines too when they 1st came out. Not as plentiful as hay/water for horses or wood/coal for steam engines.
Major break-through will be when Japanese bike-manufacturers develop standardised interchangeable battery-packs. They're working on that right now! Then you can just pull into service-station and swap packs and off you go. Currently, EV in U.S. is pain-in-ass because of charging and NIH-syndrome. Can't even standardise on charging connector because everyone wants their system to be standard. In Europe & China, you can pull up to parking-metre at kerb and hook up to standardised charger (and pay for it same as parking). Range is PIA as well. Tesla's spent all this time, energy and money on making their already-fast cars even faster! Who cares? Gimme double range for it to be more attractive. On way back from Prescott for Thanksgiving, we had to sit for 45-minutes while damn thing charged! Doubled time required for trip, next time I'm riding my bicycle!!! Short range is actually attraction for me... sort of... I'm seriously thinking of building EV-track bike... target 250-lbs with 40-mile range. Using tiny, minimal battery-pack will let me get weight down. And making it swappable will let me have 2-3 extra packs in pits charging while I'm out on track. Then come in after each session and just swap packs and I'm ready to go! EV is going to be savior of my favourite track, Laguna Seca! Damn all those yuppies and their McMansions next to track. I'm gonna organise Harley/cruiser group-ride through their neighborhoods next time I'm out there!!! Last futzed with by DannoXYZ; January 12th, 2022 at 03:24 PM. |

Rural areas may have more difficulty with electric, but we have an electric car and husband has an electric motorcycle (which is his first choice of bikes, unless we're going a long way). Charging isn't more expensive than gas, and at least here in SoCal there are a *lot* of charging stations. We could probably do road trips, even with out 65-70 mile range car, (on a bike road trip we stop every hour anyway) given how many quick-charge stations are around. We don't, the other car is more comfortable for long trips, but it is possible. People do them with Teslas.
For our driving needs, charging at home overnight is almost always enough. Once in a while we will use a public charge station but it's not common. I will say it's nice to know that your car is fully charged every morning. |

Very interesting indeed so some of you actually have Electric vehicles ! that a good thing actually as you won't be caught in the rush to get one in the future !
.... Yes long range on bikes is not mandatory as I have to get off anyway and give my butt a break... and the bike could be charging while I grab a bite to eat but quick charging is a necessity..... not just a want ! .... I think in 20 years for a substantial amount of money you will be able to buy self recharging batteries and assemble your own battery pack that will be capable of thousands of miles at a time.... however most people will not be able to afford it ! and if the neucular battery ever gets off the ground that will make EV's the way to go. but at present I can't see it myself. .... I stopped by Walmarts "Charging station" one time and for a 30 minute charge they would charge your credit card $50.00 !!!! How is that cheaper than gasoline ? so it would cost me nothing to go there and shop ( as I would charge it at home) but $50.00 to get home.... EVERY TRIP ! at present I can get there and back 3 times (perhaps 4 times) on $40.00 of gasoline in the Honda CRV.... the thought of paying that much every trip is scary . ..... I see in the future it is possible that the private sector like the power company will set up Tesla towers and broadcast electricity which will be the way to go.... but it will be costly. it's possible but unlikely, even the state might do that and just raise your taxes to a outlandish amount to pay for it ! but that is in the far future and we will have to take dealing with the transition ourselves. to get along without gasoline is do able with the internal combustion engine you can go 100% Hydroxy gas or wood gas or bio-gas i.e. alcohol and such so running out of gasoline is not the end of the world.... and we have a few decades before that happens anyway.... 20 years from now I think alot of people will be in a world of hurt because of transportation... and many will choose the horse and buggy ! LOL... Bob......

Seriously... steam is the way to go ! use wood pellets for the fuel and a small double action steam engine and your good to go.....
.... Makes me wonder if I could convert the Honda CRV to steam ! LOL ....i could make the steam engine on the lathe build the boiler to fit the back of the car and make a automatic feeder for the pellets.... .... but I think that's a bigger project than I want to tackle I'd need a truck for that to be practical .... HAHAHAHAH ! ..... there has been a few steam motorcycles built over the years most had short range but they did work.... one carried his boiler and all in a trailer ! you can use ANY fuel that burns in a steam engine from diesel to wood to peat. .... if you think forest fires are rampant now wait till steam engines get on the road again ! LOL Like "But I don't want that forestry approved screen on there it slows down the draft ! " HAHAHAHA .... Bob....

A electric car with a generator in the trunk that you can pull out and charge your car is the way to go.... problem is that generator takes gasoline too so what have you gained ? ....

Due to extra conversion steps: gas to electricity, electricity to battery, battery to motor, you've got extra losses compared to gasoline direct-drive.
In S.F. Bay Area with high cost of electricity, EV costs same per mile as gas auto getting 30mpg. Now that I'm in Phoenix area, electricity costs lots less (SRP has nuclear power-plant), but it still cost equivalent to 45-mpg auto per mile. That's just variable operating costs too, not including initial fixed cost of installing 220v line and chargers in your garage. Free public charging has been decreasing availability every year with costs going way up. Until they make entire EV system more efficient, best deal is still Prius hybrid @55mpg with generator in frunk. |

Back to our regularly scheduled programming...
He's missing coolant hose. Thought extra loose vacuum hose might have been swapped onto carbs. But nope, from photos, it appears all vacuum hoses on carbs are correct. Idiot mechanic probably left it on bench somewhere. |

That correct that just the radiator overflow vent for the expansion tank hose it is usually routed down between the frame in back of the engine just in front of swing arm Just pick a reg vacuum hose being it is not under any kind of pressure or continuous coolant flow for it, or you can just order the original part number 390620191. |

Better listen to Anthony on that....it may well not handle it....
but it shouldn't be that hard to replace later...and it's easy to use to see if the bike will actually run ! .......Bob.....

Alright, so, I went and got a connection hose as recommended above. Connected the two remaining things correctly and started the bike. The bike starts, idles perfectly fine for some time (until it's still cold and starting to warm up).
Now there are two issues: 1) I still can't open the throttle, cuz as soon as I do that, the bike dies. If I put the choke on, it will rev up naturally to 5-6k rpm. But any more throttle and it will die. 2) As soon as the bike is hot (left it running on the spot for 7-8mins) the coolant reservoir (white container thing on side) started to bubble up, looks like the hose from the radiator is sending hot air through the hose into the bottom of reservoir. So I panicked and turned her off and I can't dare to start her up again. I've clearly connected a hose wrongly. (See the attached for reference please) Where did I mess up now?

Here tip keep radiator cap off and start engine set the choke to on to keep rpm up you may see drop in coolant give it a minute then top it off, if need be, with coolant then put the radiator cap back on. Oh, and used the choke to set rpm at least 3k I'm sure you wonder why seeing air bubble because it gets trapped in the coolant passages if it ever got drain even a little bit, even that carburetor coolant hose to, now air can expand under heat causing it to make it way to the top of radiator and causing the cap to opens under greater pressure therefore making its way into the reservoir as steam and that's is the whole purpose of the overflow reservoir to draw coolant back into the radiator.

I agree Anthony even though your typing is hard to follow <grin>
but please note DO NOT USE WATER ! it takes a 50/50 mix of antifreeze or engine coolant and water in these bikes for the cooling system to work. if it's got water alone in it , just drain it out and put in a 50/50 mixture in it. you can't run just water in it ! the antifreeze has a wetting agent in it and helps the thing cool much better.... without it it will over heat ! .... Bob......

If still bubbles and steam into resevoir, do compression-test. Also get testing kit to detect combustion gasses in your coolant. |

I totally agree Danno the non reving is DIRTY CARBS !
....but for me the air in the coolant is a weird one as almost all my experience has been with air cooled motorcycles not water cooled. so I can't help on this issue alot of the symptoms do point to a blown head gasket but i've only experienced that in cars and a few air cooled bikes... not motorcycles ... I would get the carbs working right and then tackle the coolant problem as a separate unrelated problem. it is more work that way but, doing them both at once may well introduce more problems before you get it running perfect.... .... Bob.....

Looks like the pilot circuit with the 4 way split is causing yet another owner to have problems running the motor....
there has to be a sure fire way to clean that circuit but to date it's wire probes ,ultrasonic cleaning, soda blasting and down right attention to detail and PEA carb cleaner....and lets not forget compressed Air ! and you gott'a do it from all 4 of those out side holes toward the center which plugs the center with the crap you cleaned out so that takes more cleaning .... testing to see if carb cleaner comes out all the holes when sprayed into one does NOT tell you it's clean strangely enough ...it should, but that really only tells you some of the cleaner is getting through it does not tell you if the flow is restricted or not.... so the rule of thumb I've always followed doesn't work very good... get all the plugged areas un plugged and sprey carb cleaner and see if it comes out all the passageways.... if it does your good to go... but not for these carbs ! the short section between the pilot jet and the intersection of the 3 other holes seems to be the culprit ! it is impossible to get a wire into and getting pressure from a carb cleaner isn't very good either as it just goes out the other holes.... ....i think a blast of 110lb compressed air directly into the pilot jet holder is the best bet for cleaning that short section.... but I did that and my carbs are still dirty....it's too lean at idle the pilot circuit is still partially plugged. so as you can see cleaning the carbs on a ninja is troublesome at best... your best option is take them off and send them to Ducattiman ! SERIOUSLY as I have had my carbs off 3 times and their still not right these carbs are HARD to clean !!!! ..... Bob.......

2: That is most likely carburetor problem as DannoXYZ posted, But I be more concerned about actually head gasket leak than carburetor right now. Hey BoB must likely that not going to be an option for him as he lives in Australia well, I agree with you send to Gordon is next best thing for him being he know the Ninja Carburetor inside and out but I'm sure that going $180 to 225 round-trip + whatever Gordon needs, and its currency exchange rates and any other fee's. Chinmay here are some options for you in your neck of the woods too look into. https://www.thecarburetorguy.com/ and http://finchrestorations.com.au/ I also check your local bike shop and ask about motorcycle carburetor specialist. Also beware you should you attempt to do this yourself be sure to pay close attention to all the parts especially the Needle Jet Collar as there a right way and wrong way to install them to also Vacuum Slide Needle Jet Left, N9VU Needle Jet Right, N9VW have marking they need to be put in the right carburetor if have two small box's label them that way you don't get them mix up and pay close attention idle mixer screw and the number of turn going in to the close with each carburetor. PEA solvents WD-40 Specialist Throttle & Carb Cleaner Spray Clean-R-Carb Carburetor Cleaner Spray B-12 Chemtool Carburetor Cleaner Spray (My fav stuff) Carb Carburetor Cleaner Cleaning Brushes Kit Very small gauge copper wire Air compressed is very used to use full MAX PSI out put Also have look at this on removing the plug https://faq.ninja250.org/wiki/Removi...re_screw_plugs I also get a carb kit Install a float needle and idle mixer parts Last futzed with by shspvr; January 16th, 2022 at 10:15 AM. |

1: Yes if you look at your own post 106 with photo which show the coolant level then if you look at your other post 111 photo the coolant level is right at very bottom of the reservoir unQuote" Very observant Anthony ! well done! ..... Yah being accross the pond is a problem with using Ducattiman .... darn it ! ..... I was going to buy one small 6x16mm bolt for my RX4 as it lost one the bolt was 50 cents the shipping was $20.00 !!!! i didn't get it ! LOL Bob....
