A weak spark
can cause a dirt bike to start then stop. There are a few reasons for a weak spark, such as a fouled spark plug or one that is too old. In these situations, replacing the plug itself is a simple fix. A weak spark might also come from a bad spark plug wire, which necessitates replacing only the wire.

mostly related to the very lean air/fuel ratio on the modern fuel injected motorcycle engine

Why is my dirt bike stalling out?
Another scenario might be
a bike running at inadequate levels, or the oil isn’t replaced regularly
. Either can result in a constricted clutch drum. When you put the bike into gear, the engine won’t generate enough power to move those seized clutch bells; as soon as you release the clutch lever, the bike stalls out.

keeping the engine under a light load (you will only be opening the throttle to 1/2 or so) If the needle is set too rich you will hear a sputtering like the choke is on and the acceleration will be slow. If the clip position is too lean
the engine will sound quiet and have a “dead” feeling possibly hesitating
.
Why does my 2 stroke rev up when I start it?
Usually means a lean pilot or an air leak
like you said. If it’s not revving too high I usually just hit the kill button a couple time until it settles down.
What makes a bike stall?
So why do motorcycles stall? Motorcycle engines stall because
the frictional load of the stationary back tire overcomes the output force of the engine, and the engine quits running
. In other words, the engine isn’t getting enough gas to push the motorcycle forward.
How do I stop my motorcycle from stalling?
Why does my bike get off when I accelerate?
You may have
excess slack on the throttle cable where it is connected to the carburetor

. Running lean means there’s too much air and not enough fuel for the engine to burn properly.
Should a 2 stroke dirt bike smoke?
Since the engine is burning pre-mix oil we have to be careful here, because
blueish-white smoke is a normal occurrence of two-stroke engine operation
. However, excessive smoke after warm up can be an indicator of a couple problems.

- Fouled spark plug.
Why is my 2 stroke sputtering?
The reason your two-stroke ‘loads up’ is because
not all of the gas gets burned through the cylinder, so it just sits in the crankcase
. When you give it some throttle, the fuel/air ratio is too high, causing it to blubber and sputter until it clears out this excess fuel.
Why is my dirt bike revving so high?
A motorcycle idles high when it is getting too much of an air and fuel mixture in a low speed or neutral position. This is
usually caused by the idle screw on the carburetor being out of adjustment, an out of place throttle handle screw, a bad carburetor throttle spring, or a sticky throttle or throttle cable
.
What does it mean when an engine loads up?
What Is Engine Load Up?
When the fuel air is taken into the engine, it is partially left unburnt in the crankshaft area
. The fuel air mixture is then compressed and burned at the top of the engine’s cylinder head.
