    Yup certainly sounds like running too lean. How many K's has the bike done, and what sort of carbies does it have fitted?

If it runs better with the choke on, you have a partially stopped up pilot jet circuit, or are running lean. If you removed the jets and were able to spray cleaner through the ports easily, then you may still be running lean. If you didn't remove the jets, then you didn't clean the carbs.

Had a similar problem. Turned out the fuel/air mixture needed a tweaking which I had the shop perform. Perfect ever since. The carbs on my Dent are very touchy and need exact settings to run right.

Bike only idles for a few seconds (hot or cold) replaced s/plugs cleaned & sync carbs, slugish till around 2500rpm but no problems after that

Clean them better, or check for off Idle fuel adjustments on them.

Also not that garbage in the tank can be clogging the internal strainer reducing flow.

Happening at only the 2500RPM area I would inspect the secondary / Off Idle Jets just above the throttle plates for clogging............ soak them in cleaning solvent, use a torch tip cleaner, blow them out with air ect.

1987 60 hp mariner idle & high idle great, stumbles/ stalls in gear on take off, head gasket or poor idle adjustment?

Clogged idle circuits in your carbs. Clean jets and passages.
You can try suck dirt out, therefore: Screw the idle mixture screw out ( almost totally ), give full throttle ( 1 second ) and then hold your hand against the carb air intake.
This will give maximum suction and can suck the dirt trough tje circuits.
Also, first drain the carb(s) to be shure there is no water in it...

My 1978 GS750 has a stumble right of Idle, any ideas? Carb settings? Thank you.

needs just a little more air on your idle mix screw and if that won't fix it, take your carb slide out and drop the inlet needle down 1 notch so as to take a little fuel away during idle, that makes it come on more crisp & clean

Hey just wona know where the air mixture screw on my carby should b set at coz i jus bought the bike n found the screw is wwound all the way in wot should i do

Most air mixture screws you never have to mess with. In your case, someone else decided to do this for you. First, if your bike is running rough, make sure you do a THOROUGH cleaning of the carbs so that when you DO set the air mixture screw, it will do its job correctly. The normal procedure for the air screw is to start with the screw a few turns out (counting exactly where you are starting from) For this particular bike, lets say 2 full revolutions. Now, with the bike running, (it should be able to run as long as the carbs are clean) screw the mixture screw out however many turns it takes until the motor stumbles a little. This can be hard to hear sometimes, so you may have to repeat this step. When it stumbles, record how many turns it took. So, for our example, 2 turns, plus you turned it out another 2 turns, making it "stumble" at 4 turns out. Now, reset the mixture screw to 2 turns out. Do the opposite and screw in now, making note of when it stumbles again. lets say it stumbled at 1 turn in. Now we know that the best possible solution is to put the air screw between 1 turn and 4 turns out, which means you should set it at 2.5 turns out (which is half way between 1 and 4 turns out). After all of that is done, you will want to double check the synchronization of your carbs to make sure they are all within spec of eachother. I hope this helps.

Bike wont idol below 2 grand

Hi and welcome to FixYa,

Almost always, the described idling problem would be a carb issue. The carbs set has to be pulled down, fully dis-assembled, all non-rubber parts soaked in carb cleaner and cleaning be done specially on the jets and pin holes.

In some instances high idle could be caused by a vacuum leak in any of the rubber coupling between the carbs and the intake manifolds.

Good luck and thank you for asking FixYa.

When start go to rev it just dies

Remove the throttle stop adjuster and the air screw adjuster and spray carb cleaner in the holes.
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Turn the pilot screw 1/4 turn counter clockwise. Check the float level. Before putting the slide back in the throat of the carb, move the clip on the jet needle one notch lower.Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. Adjust the idle speed with the Throttle stop screw. This process should get you back on the road. A “very helpful” rating for this answer? Thanks!

Misfiring, stalling. idle surges. does not idle

Tabbycat gave a very good answer. The pulse sensor could be the problem. If the sensor checks out okay then it is time to look at the rest of the CDI ignition. Next would be the carbs. ALWAYS have a fire extinguisher at hand when working on carburetors.

Drain the carburetors. There should be a screw on the lower side of each carb float bowl. Remove the screw then replace it after the fuel drains. Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, (not all bikes have a water trap bowl). Turn the gas back on and wait a minute for the carbs to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetors from the engine.

carb > Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the carb and spray into the screw holes as well.
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Put the rest of the
carb back together, clean the air filter and install the carb. Install an in-line fuel filter. Let the float bowl fill then start the engine. This process should get you back on the road.

Also, sync the carbs such that the slides on all carbs move at the same exact instant when the throttle is slowly turned from idle speed.

Please rate this solution. Thanks!

Nissan quest 93 problem

i suspect you have a dirty mass air flow sensor. It is in the air cleaner assembly with 2 anti-tamper screws on it. remove the MAF sensor and clean with carburator cleaner and a toothbrush very gently. the wires are very fragile. The MAF tells the computer how much air is flowing through the air cleaner to adjust the fuel mixture.
other posibility is TP Sensor (throttle position).
