Why does my motorcycle shut off when I stop?
Air-fuel ratio Once the engine’s air or fuel produces more quantity than the other, for example, there is more air in the engine than fuel. Hence, it means an unbalanced air ratio, which usually causes a motorcycle when stopping.
What does it mean if I have to keep my choke running so my bike doesnt turn off?
It means your motorcycle is not getting enough fuel, and this can be caused by dirty or clogged pilot jets, clogged fuel line, clogged fuel filter, dirty petcock, loss of vacuum in the carburetors, among other carburetor issues.
What should I do when my bike Idles?
So instead of getting a 12 0’clock wheelie from idle you can take off from a stop like a less crazy person if desired. Either way the solution is the same. Pull the carb bowls off. Pull the jets and clean them til you can see perfectly through them.
Why does my bike die when I start it?
If you can start and idle fine, but slowly rolling on the throttle bogs/dies, that’s the culprit. If you can make it through the bog and then it suddenly roars to life, that’s also a really big confirmation as well.
How does the idle work on a carb?
The PILOT jets aren’t delivering fuel. Not the mains. The way carbs work is there are three different “circuits” for fuel: idle, pilot, main. The idle is obviously what gives you fuel during idle. The pilot serves as a gradual step as the circuits trade off from the tiny idle circuit to the relatively large main.
Can you get a 12 0 clock wheelie from idle?
So instead of getting a 12 0’clock wheelie from idle you can take off from a stop like a less crazy person if desired. Either way the solution is the same.
Why does my dirt bike only run on choke?
You won’t see one of these on a dirt bike because the choke circuit actually just adds more fuel to the mixture with the same amount of airflow. So, a far too lean air/fuel mixture is why your bike only runs with the choke on.
What happens when you turn the choke on for a carburetor?
When you turn the choke on for a carburetor, it is creating a rich condition. This makes the bike easier to start, by increasing the amount of fuel present in the air/fuel mixture. When an engine is cold, it needs a little richer mixture in order to get up to operating temperature.
Do you need to tune the fuel mixture on a motorcycle?
Once you have the motorcycle up and running, you will need to tune the idle mixture. Every carburetor is equipped with an AIR or FUEL screw to tune the air fuel mixture at idle.
Why does my air conditioner turn off when I Turn Off the choke?
It can be caused by an air leak. Air leaks can be caused by cracks in the vacuum lines on some carbs, a crack in the air boot, or simply a loose clamp between the carb and the air boot. Remember, more air in the system means a leaner air/fuel ratio, thus causing an overly lean condition when the choke is turned off.
