No spark on 110cc chopper four stroke what wire is for the spark

Unless there is a separate compartment that you add oil to the oil will need to b e mixed with the fuel.

110cc sdg pit bike is not getting any spark what are some causes that it isn't getting spark please help!!

are you getting a spark?
if not then i would suggest the kill switch has gone o/c put a meter on it on contenunity and it should buzz out when switched

There is no firing order. Your bike has a coil that fires on both the compression stroke and the exhaust stroke (also called a wasted spark). Therefore either plug wire can go on either cylinder and the bike should run the same.On four cylinder bikes this meant that you could run four plugs using only two coils and two sets of points instead of four coils and four points.If the bike is running poorly try new spark plugs and new spark plug caps first(start with the cheap stuff). Next check the actual coil and pulse pick up or points. You may have to replace the coil only because the wires are cracked shorting.

Two stroke or four stroke. Air cooled or water cooled or oil cooled. Electric start or pullstart or kickstart. Late model or older model. Good condition or rusty and banged up. How many cylinders. Standard or modified. Accessories fitted.
And what sort of transmission work...replace a gear or replace a shaft or replace a bearing.
All these points and probably some more (special tool requirements) will have a bearing on the time required.
Sorry, but more detail is required. Cheers.

There are three things required for combustion to occur: Fuel, compression, and a spark (at the right time). One, or more, of these is/are missing.
If the bike has been in storage for more than about a year, then you can bet that the carburetor is plugged up. It will need to be completely disassembled and cleaned.
Also, check the compression. if it has a four stroke engine, it should be capable of developing at least 135 psi of compression (throttle wide open, choke fully open). If the compression is low (and it is a four stroke engine), check the valve tappet clearances. Insufficient tappet clearance will cause low compression.

check the spark plug , and the ignition system for loose wires then connect , don't forget the battery if there is no current then charge.

That tube would be the overflow tube. Your carb float is sticking open and allowing fuel to flow in constantly. You need to take carb apart, clean needle valve, and inspect or replace carb float.

DO NOT mix oil in the gas on your four stroke engine. You will foul the spark plug(s), build up deposits on the valves and head, and make a smokey, smelly mess. A two stroke engine uses the fuel/oil mix to lubricate the engine before being used as fuel. A four stroke engine has a separate lubrication system and does not normally burn any oil. As the name implies, a two stroke engine works in two strokes. The first stroke is downward, where the fuel/oil mix and air are drawn into the cylinder. The momentum from the crankshaft counterbalance or force from the other cylinder(s) drive the piston back up compressing the mix, and the spark plug sparks at or slightly before the top of the stroke. The rapid combustion of the fuel/oil/air mix drives the piston down, which is the power stroke, and then the cycle starts all over again. A four stroke engine has an intake stroke down taking in the fuel/air mix, a compression stroke up, a power stroke down as the fuel/air mix is ignited at or before the top of the stroke, and a exhaust stroke up before starting all over again. A four stroke is much cleaner and more reliable than a two stroke, but it is heavier and has less torque. A two stroke engine is much lighter and has more torque, but takes more maintenance.
