Bike keep shutting off while riding in stop and go traffic

Have a look around your carb inlet. This sounds like an air leak. Check for cracked rubbers..

Sounds like it is sucking in air from somewhere. Check between carbs or other gaskets. Good Luck

No,only on carburated engines it,idles down to the set point,on yours,it's fuel injected,pushing gas pedal won't kick idle down,should go down after a certain amount of time,does it automatically,If you start and drive a 5 mile ride and stop at a stop sign,it should idle at it's set point if there's no engine problems,which may be.5 to .7 on your tac.When you normally first start,it will idle between 1000 to 1200 rpm's,don't push on gas,let idle say 15 seconds,put in drive and go.

Hello. Welcome to FixYa. Please allow me to assist you.

What you have is this: Disconnecting the battery caused your car's computer to lose its 'base idle' parameters. This info is kept in the computer, but, removing power to the computer allows the info to be erased, so to speak.

This is, unfortunatly, a normal condition, and, easily rectified.

What you need to do: Get in the car, start it up, and drive it; simulating stop/start city traffic, and then take it out on the highway, hit passing gear a few times, pull off, and let it idle 30 seconds and repeat highway speed, and passing gear a few more times, then simulate city traffic again. You might need to apply a slight bit of gas during the idle periods of the drive. If you do it right, you can reset the base idle parameter under10 minutes.

If you have any questions, please feel free to get back to me via reposting.

Thanks for choosing FixYa for assistance today.

Check that the choke accelerated idle cam is not stuck. Check that the throttle cable has not dislodged and the outer casing is riding on the bracket. Check that the throttle linkages are free and the throttle returns to the idle adjustment stop. If all these are correct, adjust the idle adjustment to obtain the correct idle speed. 700 - 800 rpm is about the right speed.

If your Fatboy is carb equipped you need to set the idle speed a bit higher. If you're still running the stock carb, remove the air cleaner cover. You'll see a square looking plastic top on the carb. Just to the right (toward the front of the bike) you'll see a screw. This is the idle stop screw. Turn it clockwise to increase the idle speed. Set the idle speed with the engine at full operating temp. It should idle at about 1000 RPM.

If your bike is fuel injected, you'll have to take it to a shop to get the idle speed set as it's done electronically.

Good Luck

I had a similar problem, before it shut off, the rpm needle would booble up and down and then drop to 0 and shut off. After a while it would happen in the city and not just the highway. Ended up being the fuel pump, and I was also told the fuel pumps are known to fail on the mk4.

air sensor keeps fans at a constant temp.adrian,,,,,,,,,,,,,,

When you are on the bike and riding do you still have the choke out? And stop spraying starter fluid into the carbs..bad bad bad.... bikes start with out that stuff and if you need it then something is wrong.. your gonna mess something up doing that....let me know about the choke and we will go from [email protected]

Hey Tom, gonna try and help ya here...typical vapor lock/overheating is what your describing and i sure hear a lot of it w/harleys...are you using a very high grade synthetic oil , like castrol Syntec Actevo ? are you filling up w/ premium gasoline ?
make sure your timing is not too far advanced and don;'t let it idle too low...when you come to a stoplight stand up for a strech while letting your engine get air not blocked by your legs....all these things will help greatly......Good luck to you friend...Tim
