Causes of unstable motor idle must be alerted immediately. Because, this condition is quite dangerous, especially on automatic type motorcycles. Many problems can occur on a motorcycle.
Not only in important components, but all components can experience problems. There are many variants of the type of motorcycle, matic is one that is quite popular and has many enthusiasts.
In addition to advanced and modern features, the ease of driving also makes anyone feel comfortable. All types of motors also require regular maintenance.
This is to keep the components working optimally. One of the problems that often arise in the injection motor is sluggish. You could say the motor has a problem at idle.
If this happens, it’s a good idea to immediately find out what causes the motor idle to be unstable. If the motorcycle experiences a slow or unstable idle it will be quite dangerous.
This condition will make the automatic motor run even though the gas is fully closed. When idle the motor is unstable suddenly and tends to rise will be dangerous.
There are many factors that cause this to happen. As a vehicle owner you need to know why this problem occurs. So that will help solve it faster.

Some Causes of Unstable Motor Idle
Every motorcycle has a gas setting that can be adjusted to the user. But when the engine is started, the idle speed goes up and down like it’s about to die, indicating a problem.
In addition, vehicles that do not carry out routine maintenance also disrupt idle stability.
There are many factors that influence it to components that cause unstable idle. Actually the main cause of this condition occurs is due to sensors Idle Speed Control (ISC) is broken.
Problematic ISC
The first cause of unstable motor idle is the result of a problematic ISC. Usually the spring in the ISC area has started to weaken. So that makes sluggish so problematic.
If the ISC has a problem, it is not only idling that is suddenly high, but the motor may not want to slow down at all. This sensor is located on the Throttle Body (TB).
ISC inspection or maintenance can be done when disassembling and cleaning it. We recommend that you do it if the motorcycle is more than 3 years old.

Busi
There is a cause of unstable motor idle which is then due to spark plugs. You should check the condition of the spark plugs whether they are still in good condition or not.
As is known if the spark plug acts as the first ignition of the combustion process.
Spark plugs can also have problems if they are dirty or have been used for a long time. A spark plug gap that is too wide will result in a small electric spark.
This will result in the explosion in the combustion chamber getting smaller too.
Noken As Troubled
When there is a problem with noken, it can also cause engine performance to be disrupted.
This will be the cause of unstable motor idle. Starting from the beret that makes the intake and exhaust valves not closed completely.
When noken as a beret, it is better to replace it immediately. This is because the camshaft is one of the vital components on a motorcycle.
Valve Slack
Adjustment or clearance of the valve affects the condition of the engine motor. In addition, it also has an impact on more extravagant fuel consumption so that the cause of the motor idle is unstable.
Not only that, the motor engine is no longer powerful, the engine noise is noisy, and the occurrence of overheat. If the problem has occurred immediately to fix it.
You can re-check the clearance on the valve with a size of 0.8 mm to 0.10 mm. We recommend that you adjust to the standard. Use a feeler gauge to adjust the valve clearance.
In addition, the problem of positioning or changing the valve seat can also affect the valve closure is not perfect. So that the engine performance from rotation at idle is disturbed.
Clogged Sprayer
The carburetor component that can affect the engine idle speed is the nozzle. A clogged nozzle is one of the causes, so you need to provide proper treatment.
The way to fix this is to remove the sprayer and clean all the holes. By providing proper maintenance, the cause of an unstable motor idle can be resolved easily and quickly. (R10/HR-Online)
