Why does a 2 stroke bog at full throttle?
A loose spark plug causes bogging because it doesn’t reach far enough into the combustion chamber to ignite all the fuel. A spark plug can become loose from vibration over time, or if it wasn’t properly tightened to begin with.
Why is my 2 stroke bogging down?
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.
What causes a 2 stroke engine to bog down?

When the bike is at an idle, it will bog if you open the throttle all the way to fast. It is still rideable but sometimes when it happens it is always at the wrong time. My plug is lightly oily and black.
What makes a 2 stroke engine the best?
Jet more by “feel”more than plug color on a two stroke. Two strokes make the best power at low engine temperatures and that combined with oil in the fuel and cold heat range spark plugs makes for a good plug reading that is darkerthan most would expect to see.
Is it OK to run a 2 stroke?
Keep in mind that a 2 stroke will never run “clean” like a 4 stroke and a good running 2 stroke will have situations where it sounds too rich. This is OK as long as it cleans out instantly when throttle is applied and there is no hesitation or bogging. Temperature and Altitude Correction Chart

What to do if your bike Idles but bogs with throttle?

When to turn off choke on 2 stroke engine?
There is a simple solution for this one, but it’s an easy one to forget. Turning the choke on is important for starting a cold engine, but it should be turned off once the engine is warm enough to stay running. The choke creates a richer air/fuel mixture to be able to idle on first start up.
