Bike warms up let it run for about 20 minutes and then give it gas and it begins to stall and then dies and willnot start back up

    Well if the bike isn't out of gas. It could be the bike stata ( I might have spelled it wrong). But that is what it sound like it needs. The part keeps the battery charged like the alternator on a car.

    I would also check the fuel lines and make sure fuel is pumping. Because it also sounds like gas is being sent for the start but not maintaining

Have the carburetors serviced. Sounds like a fuel pump problem(if your bike has one). If not it is because the idle mix is too lean.

SOURCE: stalling out

u have the mixture screw wound in to far. its normally located on the bottom of the carb. try winding it out half a turn at a time once the bike has warmed up. also turn the idle screw out a quarter of a turn at the time its in to far thats why it idles at low revs. the choke is needed to keep the air fuel mixture right thats why u are having to leave it on for so long. hope this helps.

SOURCE: wont start

Hi and welcome to FixYa,

Appreciate the direct "Ask Me".

Your described problem based on the bike being a 1982 model could be varied, among them are:

  • weak spark - not necessarily weak battery. Culprits could be loose loose connector to the CDI, low IGN +12 to the + terminal of the coil (check with a voltmeter while just switch on and when cranking/starting), or even a loose ground terminal. Check spark by removing plugs, reconnect the plugwires, let the threaded end touch metal part of engine, crank. Sparks should be strong;
  • corroded/poor contacts in the ignition switch resulting to the above. You can test by running a jumper wire straight from the battery to the + terminals of the ignition coil;
  • too lean air/fuel - plugs should be brownish in color;
  • air or vacuum leak - resulting to the above and high or poor idling;
  • unbalanced carbs - carb check/clean, verify air adjustment screw number of turns,
  • compression low - have a compression check.
Would look forward to your updates. Good luck and thank you for using FixYa.

SOURCE: Suzuki wont start

Ive found that the carbs need the coreect airflow to work correctly.If you dismantle the carbs and make sure all the air passages are clear from blockages.Ive got an early gs550 in a gokart and it had no airbox and it was doing the same untill i covered some of the carb throats with my hand and then she would rev her nuts off.if you take any air screws out mark there position and count the turns out to place them back in the same place.Im making my own manometer using some 4mm hose a garden sprinkler 4mm attachment and a cheap airflow meter from cip1.com.

running the correct air box is crucial and the filter must be clean.

hope this helps David New Zealand

SOURCE: DR 200 runs really cold. Takes about 15 minutes or so to warm up

It depends on the tempature, if its pretty chilly out yeah. Try easing the choke in slowly, and when it will idle at about half choke go aheand and take off but run the bike easy for a few minutes then close the choke.

It will crank and run good for 10 minutes and shut off. Once it shuts off when you restart it, it will only run for a couple of minutes and shut off again ?


I would start by getting a can of carburetor cleaner and have it 'at the ready' and try the 'start, run stall, start run stall' operation again. Only THIS time, once the engine begins to stall, give it a couple of quick shots of the cleaner into the air filter to see if it stays running on the cleaner.

If it does, then it's still a fuel problem. If it doesn't, then it probably an ignition problem. I would be sort of leaning towards the ignition coil getting weak. The reason I'm saying that is your statement about it running (I'm assuming cold start) for at first, 10 minutes then it stalls. Start it again and it runs for a couple of minutes and stalls again.

This could possibly be from the coil getting warm/hot and not producing the needed spark. After a 10 minute run it simply gets too hot and stalls the engine. After the next restart, the coil is already warm from the engine and so it don't take as long for the coil to get hot and stall the engine again.

Hope this makes sense and helps you out.

Mercury boat motor troubleshooting


Could be a fuel issue. You don't say how old your motor is, but if it is 10 yrs or older, there is a good chance it does not process regular highway fuel very well. Too much ethanol. Makes the fuel separate after warming up. Your engine will normally start fine, but after getting warm, will either stall out at low speeds, or won't start after shutting down. Try a good additive to reduce the ethanol effect. Most boat docks with fuel pumps also sell the needed blend of gas for marine engines. Thus, a few more cents per gallon, but less problem for you. I mixed a good additive to my 20 yr old Johnson 115, and it runs like a new one! Hope this helps. Good luck !

2008 boulevard 1800 fuel injected engine. Engine starts to stall once warming up, 6 or 7 kms, at no throttle. Seems to straighten out if I throttle hard for 4 or 5 seconds. Bike had 1700 kms when I got it...


Hello,
It does sound like you have dirty or clogged fuel injectors. The best way to fix that is to add a bottle of fuel injector cleaner into your gas tank and that will clear the issue as you drive the bike around enjoying the sights.
Good Luck!

My gmc 4.3 stalls when warm and wont start without ether. then it runs fine


I had the exact problem with my 1993 chevy c1500. I found that the IAC was sticking so the engine would die at idle after warming up and the ignition module was pulsing the ECM intermittently after the engine warmed up so the fuel pump wasn't being turned on after the engine died....I replaced the ignition module and the IAC valve and all is good. I don't know if testing the ignition module reveals that it isn't sending pulses to the ECM.

Acceleration problem


possibly camshaft position sensor in the distributor, or weak fuel fump starts acting up when warm, or throttle position sensor. heat has a effect on sensors and electrical components in some weird and hard to find ways.

4 cyl Engine starts and idles ok...give it throttle and it dies


I need to get a clear mental picture of what exactly is happening.

With this said, you stated that the car "runs fine" until warmed up.

Q: When you start the car when cold it idles fine?
Q: If you allow the car to idle until "fully" warmed does the car stall?
Q: As the car begins to warm up, Does the RPM fluctuate abnormally?
Q: Does the car Only stall when you press on the gas pedal or does it stall just sitting and idling in addition to pressing the gas pedal?
Q: If you can drive it while cold does the car stall during acceleration when warm or only at Stop Signs / Lights?
Q: If you wait 20min or so, can you start the car again?
Q: How many miles are on the car?
