Why does my dirt bike cut off when I give it gas?
Dirty Air Filter As the air filter cleans the air entering the carburetor, it will eventually become dirty or clogged and may prevent the proper amount of air from mixing with the fuel, causing your engine to stall.
How do you tell if a 2 stroke plug is fouled?
A fouled spark plug occurs when the plug isn’t burning fuel normally, leaving damage to the plug which can cause the engine not to start. A normal spark plug will appear dry with a grayish color. A wet spark plug can indicate water in the fuel while a white residue on the plug can point to a plug that is too hot.
Why does my 2 stroke keep cutting out?
3. Fuel Tank Cap. Another common cause of bogging down can be the fuel tank cap. The obvious effect this has on the engine is less fuel getting into the carburettor, which can contribute to the engine bogging down and eventually it will cause the engine to stop completely.
Why does my 2 stroke dies when I give it gas?
Carburetors mix air and fuel at a precise ratio for the combustion process. Anything that prevents the proper airflow or entry of fuel will result in the inefficiency of the carburetor. This can lead to the symptom of your two-stroke engine dying at full throttle.
How do you know when a 2 stroke needs a new top end?
While most 2-strokes are easier to kick over than a four-stroke dirt bike, you shouldn’t be able to push the kick-start lever down with one finger. If it kicks over with next to no resistance, the top-end is probably down on compression.
How much does a top end rebuild cost for a 2 stroke?
How Much Does It Cost To Rebuild A Top-End 2 Stroke? The cost of rebuilding a 2 stroke dirt bike top end can vary from under $50 to $500+. It depends on what parts need to be replaced and if you’re doing the rebuild yourself or paying someone else to do the work.

What should the compression be on a 125 2 stroke?
