It could be a number of things, like a broken or worn ring, or a leaking head or base gasket. If it happened suddenly, I'd suspect a broken ring. If it happened gradually, I'd suspect it's a wear issue. If it's accompanied by a noisy piston, (sometimes called, "piston slap") then I would suggest it's time for a top-end job. Good Luck
It's a dirt bike that uses a 2-stroke engine.
It has a Honda engine with the following specifications: 83cc's single-cylinder two-stroke, compression 8.4:1, bore x stroke is 47.0 x 47.8 mm or 1.9 x 1.9 inches. The engine is liquid cooled.
No compression could be various things from your piston to your crank start with your piston by doing a compression test
no compression (easy to push kick starter down)
when bike is at rest the piston is any where within the cylinder ..now when u again start up the engine by a kick u actual set the piston to the TDS(top dead center) and the hardest kick u give is for the suction stroke to take place which also due to inertia lets the compression stroke take place and so does the power stroke happens due to spark ignition or by compression ignition and so the engine starts operating................. hope u got it.........lean more on utube.....videos....
For the same engine size, it should be.
Two strokes can accelerate faster but it depends on engine size
if we use 2 stroke diesel engine in our bike then engine get more vibration & noise so it is not comfartable to the rider so it cant use in our bike
A 70cc bike can be either a 2-stroke or a 4-stroke engine, as the displacement refers only to the engine size and not the type. Both engine types are commonly found in small motorcycles and scooters. The choice between a 2-stroke and a 4-stroke depends on the bike's design and intended use, with each having its own characteristics in terms of power delivery, efficiency, and maintenance.
All of the Orion bikes use a 4 stroke engine.
2 stroke
that engine code is not a four stroke, its 2 stroke 80cc
