Try the link below for an answer. It is for a different bike, but it is a possible solution.

The Honda 1100cc Shadow/Shadow Sabre Engine puts out about 65 hp.
to much fuel is going to the engine for it to burn it all
Backfiring on deceleration is normally caused by excess fuel being ignited in the exhaust system.
probably a bad spark, itll cause your engine to misfire flooding petrol in without igniting it, when it sparks afterwards it ignites causing a bang and backfire.
Just over 67 cubic inches
It depends what CC it is! 100cc will go about 60mph. Adddition: It also depends on type of engine. A 1100cc V-twin engine will perform a lot differently from and 1100cc inline 4 cylinder engine. On top of this, it depends on what your definition of fast is as all of these engines produce different amounts of power at difference rpm ranges. Lastly, an engine has very little to do with the speed of the motorcycle in a turn and this all comes down to suspension, handling characteristics, and largely the skills of the rider.
1100cc refers to the engine displacement of an internal combustion engine, specifically measuring 1100 cubic centimeters. This measurement indicates the total volume of all the cylinders in the engine, which can impact the engine's power output and efficiency. In general, a larger displacement often correlates with greater power, but it can also affect fuel consumption and emissions. Commonly found in motorcycles and some cars, an 1100cc engine strikes a balance between performance and practicality.
The horsepower of an engine is not solely determined by its displacement (like 1100cc), as it also depends on factors such as engine design, efficiency, and tuning. However, a rough estimate can be made, with 1100cc engines typically producing between 70 to 100 horsepower in motorcycles, and slightly less in cars. For a more accurate assessment, it's best to refer to specific engine specifications.
Your grammer is awful. 150cc refers to the cubic capacity of the piston chambers inside the engine. Generally the larger the capacity the more power an engine produces. There is no way to tell the horsepower of an engine from its capacity. My motorcycle produces 147Bhp from its 955cc engine. My car only produces around 60bhp from its 1100cc engine.
Incorrect Timing Can Cause Backfire.
what is making my Lincoln ls v8 backfire under the engine
A flame arrestor. This prevents a backfire from igniting gasoline vapors in the engine compartment.
