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.
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.
Several things could make a carburetor backfire. The engine could be out of time. the carburetor could have a stuck float, or the engine could have a stuck valve.
No, backfire is usually caused by park plug wires that are installed incorrectly or an engine that is out of time. Fuel filter and pump will not cause backfire.
