Why is my motorcycle losing power when accelerating?
There are six main reasons why a motorcycle loses power when accelerating which are: Plugged jet in the carburetor. Broken carburetor spring. Vacuum leak on the carburetor or intake boot.
Why does my bike keep losing power?
Loss of power may also be caused by an improper level of oil in the engine. Too high a level will lead to froth introducing air into the lubrication system and reducing the ability of the oil to lubricate the moving parts.
Why does my motorcycle sputter when I give it gas?
The problem of having an engine “sputter” is typically caused by a fuel system issue. For pit bikes with smaller cc displacement engines, in order for a cylinder to fire efficiently, three separate components must work together; the fuel delivery system (carburetor), the ignition coil and wires and the spark plug.
Why does my dirt bike bog down when I give it gas?
Fuel Injection Issues
If you have a fuel-injected dirt bike, the bogging could be caused by problems with the fuel pump or fuel filter. With a fuel-injected dirt bike, use a high-grade fuel cleaner to get rid of dirt and debris that could cause blockages with the pump and/or the filter.
What causes hesitation accelerating?

What would cause loss of power when accelerating?

Why is my dirt bike sputtering?
There are several reasons why a motorcycle sputters. The most common reasons are carburetor issues such as a vacuum leak, fuel leak, or tuning issues. Other culprits could include corroded or cracked spark plugs or spark plug wires, a faulty ignition coil, a clogged air filter, or engine timing issues.
Why do 2 strokes pop?
The cause of this very intense combustion is a considerable buildup of unburned fuel, unburned due to the repeated misfires caused by the stagnant exhaust gases (still trapped in the cylinder because of poor scavenging due to the low differential pressure we have between crankcase and cylinder when the throttle is held …
Why is my 2 stroke misfiring?
An oily build up on a spark plug will cause the spark plug to misfire. Oily build ups are very common on 2-stroke engines from improper mixture of the oil and fuel. To check this, remove the spark plug, inspect it, clean it off, gap, and re-install.
What is surging in a 2 stroke engine?
The most common causes of a two-stroke engine surging include lack of airflow, contaminated fuel, faulty or old spark plugs, or a maladjusted carburetor. Fixing each of these issues involves removing parts of the engine, inspecting, and possibly replacing the equipment.
