How do you find Top Dead Center on the compression stroke for the 1 piston on a motorcycle?
If you don't have a timing mark or cannot find it you need to do this. Find out which cylinder is the #1 cylinder and pull the spark plug out of it. To make it easier to turn the motor over it is best to pull out all to the plugs so you aren't fighting the compression of the other cylinders. Next put a wrench onto the crankshaft pulley on the front of the motor. There should be a bolt there that holds it on. If not, you can turn it by hand. A second set of hands is always good also. Next once you have the plugs out, put you finger or thumb over the hole of the #1 cylinder's plug hole. Then turn or have a friend turn the motor until you feel pressure against your finger. Once you have this figured out you can take a straw or something that won't break and put it down into the cylinder. Going slowly, turn the engine until it looks to be all of the way out, (the straw). This is a good way of getting the timing close. Just remember that this is for ignition timing only. If you have a newer motor that has a 0 tolerance on the valve timing and you just "get it close" you will be smacking pistons into the valves. This however is an easy way to check and see where your distributor and #1 one cylinders are at.

How can you tell if your on the compression or exhaust stroke?
You can determine if you're on the compression or exhaust stroke by observing the position of the piston and the alignment of the crankshaft. When the piston is at the top dead center (TDC) and both valves are closed, it's the compression stroke. Conversely, if the piston is moving down from TDC and the exhaust valve is open, then it's the exhaust stroke. Additionally, you can feel for air pressure at the spark plug hole during the compression stroke.
At what position is top dead center on a crate 350?
the piston in cylinder #1 at the top on the compression stroke
Is top dead center the compression stroke?
Top dead center (TDC) refers to the position of a piston at the highest point in its cylinder. It can occur at the end of both the compression stroke and the exhaust stroke, depending on the engine cycle. During the compression stroke, the piston moves upward toward TDC, compressing the air-fuel mixture before ignition. Therefore, TDC is not exclusively the compression stroke; it is a position that can be reached at different points in the engine cycle.
What are the advantages a mechanic could get if he is skillful in setting piston to top dead center compression stroke?
yeah men
What piston must be at the top when firing order is 1-3-4-2?
#1 piston must be at TDC / Top Dead Center on the compression stroke.
What causes no compression in a 2 stroke dirt bike?
No compression could be various things from your piston to your crank start with your piston by doing a compression test
Are both dots on crank and cam lined up at top dead center?
It will be if #1 piston is at TDC on the compression stroke. When they are lined up.
What position is the pistons when at top dead center?
At top dead center (TDC), the piston is at its highest point in the cylinder, positioned at the very top of its stroke. This occurs at the end of the compression stroke for the intake or compression cycle, and at the end of the power stroke for the exhaust cycle in a four-stroke engine. At this position, the piston is effectively at the zero-degree mark in relation to the crankshaft. It is crucial for timing events in the engine's operation, such as valve opening and closing.
How fuel works in cars engine?
All gasoline engines are four-stroke designs. An engine has an intake stroke where the intake valve is open and the piston is moving downward, creating a vacuum that sucks the fuel into the cylinder. The next stroke is the compression stroke. The intake valve closes, and the piston begins to move upward and compresses the fuel in preparation for ignition. The third stroke is the power stroke. The piston is approaches the top of the cylinder in the compression stroke. Just before it gets to top dead center, the spark plug fires and ignites the fuel. The fuel rapidly expands and pushes the piston down with great force. The last stroke is the exhaust stroke. In this stroke, the piston completes the power stroke and begins to rise again. At this point the exhaust valve opens, and the piston forces the exhaust out of the cylinder in preparation for the intake stroke.
What is the distance a piston travels called?
The distance a piston travels within the cylinder is called the stroke. It is the distance between the top dead center (TDC) and the bottom dead center (BDC) positions of the piston.
Which type of the engine brake uses the compression stroke of the piston as its retarding stroke?
You're talking about an engine compression brake, commonly referred to as a Jake Brake.
What are the Strokes of the four-stroke cycle?
The four-stroke cycle consists of four distinct strokes: intake, compression, power, and exhaust. During the intake stroke, the piston moves down, drawing in a mixture of air and fuel. In the compression stroke, the piston moves up, compressing this mixture before the spark plug ignites it during the power stroke, which forces the piston down. Finally, in the exhaust stroke, the piston moves back up to expel the burnt gases from the cylinder.
