What does it mean when your ATV won’t idle?
When the engine idles fine but won’t rev up, it is a sign of it getting too little fuel, but it can also be because it is getting too much fuel. The ATV may run fine at low speeds, but as soon as you apply a little or a lot of throttle, the engine will bog down and turn off.

Why does my motorcycle not start when I turn it on?
Clogged Injector Symptoms of a clogged injector: Your motorcycle will attempt to turn over normally when you try to start it but there won’t be any combustion. If you know it’s sparking correctly and that there is gas in the tank but it has been sitting for a while, your culprit is probably a clogged fuel injector.
Why does my dirt bike not idle properly?
Going leaner/smaller on the pilot jet may cure the problem and get your bike to idle properly again. A dirty carb, and more specifically, a dirty pilot jet circuit is one of the most common reasons why a dirt bike won’t stay running.

Whether your dirt bike won’t stay running, or it runs rough, internal wear or damage can wreak havoc on your riding time. In an attempt to save money, find the same bike as yours with a known working carburetor. If you’ve tried every other jetting change, swap your carb with it and see if your problem is fixed.
What causes a carburetor on a motorcycle to not start?
If you have a motorcycle that won’t start, the carburetor may be dirty and will need a good cleaning. This means that the jets inside are probably clogged with deposits which means no fuel can pass through at all.

What should I do if my motorcycle won’t start?
Unless you have one of those new all-electric motorcycles, your bike needs three main things to run- Spark, Fuel/Air mixture and Compression. Your bike will either run rough or not start at all without the proper amounts of any of those elements.

What do idle Jets on a bike look like?
To get an idea what they look like simply do a search in google images for idle jet.It’s just a case of removing the float bowl to get at them. What condition is the inlet manifold in?
Why does my motorcycle engine stall when warm?
And the problem is often worse on a hot day. The dreaded stalling issue when the engine is warm is the most common idle problem and it is mostly related to the very lean air/fuel ratio on the modern fuel injected motorcycle engine. Why does my motorcycle stall at idle when the engine is warmed up and at operating temperature ? – Low compression.

Why is my motorcycle idle speed too low or too high?
If you aren’t going to set your idle to the factory level then you should always aim for high idle speed over lower. If your bike has been warmed up and is idling lower than the recommended level from the manufacturer, you probably have a couple of problems: The engine will stall easily or may not stay running without throttle being added.

Where is the idle button on a motorcycle?
The screw is usually located on the carburetor near the choke. This same screw system is used on the first generation of fuel injected motorcycle engines. Newer models that have fuel injection systems have an ECU (Engine Control Unit) that controls the idle level. If your bike has an ECU you cannot adjust the idle easily.
Why does my dirt bike not turn on?
As there engine temps rise, less fuel is required to keep it running. This is why some dirt bikes need to have the choke on left longer to keep them running without needing to give it more gas by twisting the throttle. 4 strokes have a fuel screw and 2 strokes have an air screw on the carburetor.
Why does my bike engine not rev up?
You can have fuel in the pilot circuit but if the air supply is blocked off, then engine would not rev up. On my carbs, the pilot jet air comes in through a hole at the carb front, goes down through a hole in the bowl gasket, along a passageway, and mixes with the pilot jet in the bowl.
What does it mean when a motorcycle Idles high?
When a motorcycle is idling high, that means there is too much of an air/fuel mixture at a low speed or in neutral position. Essentially the combustion reaction continues to occur more frequently when the motorcycle isn’t going fast, or really going at all.
What to do if your bike won’t run without a choke?
Normally you would keep it on (closed) until the engine warms up and then turn it off (open). If it really won’t run without the choke being closed/on then it’s not getting enough fuel and the carbs probably need cleaning.

Or, you could have air leaking around the throttle, just enough to lean it out at idle; the mounting boots could be the leak, or diaphragms in the carbs, that kind of thing. Wow, thanks both of you!
