Standard plug Innate motor each launched from the manufacturer. Material ends of the nickel electrode and center electrode diameter of 2.5 mm on average. Distance can use standard plugs to 20 thousand km, when the normal combustion conditions and other factors not influenced by kinds of engine oil and fuel consumption of excessive effect of increased spec carburetor.
Preferred the buff bikers touring, because of his ability. The tip of the electrode is made of nickel and platinum center electrode, so that the influence of heat to the metal platinum is smaller. Center electrode diameter of 0.6 mm - 0.8 mm and do not be surprised, when the life of spark plugs age range from 30 thousand miles.
It could be said spring competition, crowded in-tuner applications for non-standard engines. Typically the tip of the electrode is made of nickel and iridium alloy center electrode of platinum opaque color. Center electrode diameter of 0.6 mm - 0.8 mm mm. And the age of the spark plug is about 50 thousand to 70 thousand miles. The advantage, suitable for long-lived large engines above 150 cc bike.
Spark plugs were designed and prepared with materials resistant to high compression, and high engine temperature as well. And be prepared to be able to compensate for the use of full throttle and deceleration.
Racing spark plugs are not the same as Iridium spark plugs. Center electrode diameter is relatively small tapered needle sorts. Age plugs are also relatively short at 20 thousand - 30 thousand km, was dominant when the engine rotates at high rpm above 6000 rpm at high engine temperatures.
Busi Resistor
Ini dia busi yang sering mengecoh konsumen, logo R latin dengan font
miring banyak yang mengira artinya racing. Dan sebenarnya R itu artinya
resistor. Busi ini dipakai untuk melindungi perangkat elektronik digital,
berupa speedometer, indikator pada kendaraan yang memakainya, terhadap
pengaruh gelombang radio dan sejenis nya. Maka, busi ber-kode R pada
busi mesti diingat, sebagai perlindungan perangkat elektronik digital
motor.
Commercially available are also two kinds of plugs that heat and cold. A lot of confusing information usability issues both these types of plugs. The following explanations characterize and when to use these plugs.
Area of residence
Special cold temperature regions, such as mountainous areas and highland, most fit to wear hot plugs. Therefore, use cold plugs will accelerate the buildup of crust. Medium, heat a wide area or metropolitan waterfront, better wear a cold spark plugs. To prevent the occurrence of pre-ignition or premature combustion.
The capacity of the engine and the compression ratio
High compression ratio and a large capacity engine, both generate heat. The logic is simple, the greater the value of the capacity of the engine, the heat contained also higher.
Here plugs also determines the quality of combustion, with limits above 150 cc, you should use cold type spark plugs. And remember, daily motor manufacturer adheres designed a low compression ratio, the relatively low temperature to heat. And machine capacity factor which should be used as guidelines.
conclusion
Thus, the use of plugs that fit the engine could, based on the factors;
- A mixture of fuel and air
- Comparison of the compression
- Ignition Timing
- Octane Fuel
- Use of standard or racing style
- The temperature of the area around
IDENTIFY PROBLEM OF MACHINE CONDITION spark plugs
In addition to errors caused by the use of the type of spark plugs, there is another common problem. What are the problem?
Excessive crust at the end of the spark plug
- Part ignition broken, between CDI, coil and spark plugs cop
- Too old to drive a motorcycle at low RPM
- Code spark plug too cold
- Fuel and air mixture is too fat
- Code spark plug is too hot
- Settings air / fuel too dry
- Crust buildup in the combustion chamber began much
- Too often full throtle

EFFECTS OF MEETING OR SPARK PLUG GAP tenuous
Often experienced by all motorists, sometimes slit center electrode spark plugs to change, tend to move closer or sometimes stretchable. In keeping with tradition, the center electrode spark gap is sometimes addressed by the motorist. What is its effect on the engine when it is too tenuous and meetings?
Gap meeting
Ignition will weaken or small and do not fit with the burning, the downside. But the advantage, always spark plugs fire in any increase in engine rpm with a tight curve.
Gap tenuous
The disadvantage, ignition at high rpm and speed will be chaotic, but the ignition stronger and more complete combustion that occurs at low and medium rpm

KNOW THE SPARK PLUG
terminal
The top of the spark plug that is connected to the ignition system
Insulator (wrapping center electrode)
The main part of the insulators made of porcelain or ceramic, to provide mechanical mounting of the center electrode, so that the high-voltage electricity can be insulated. Ceramic heat also helps burn crust deposits.
Ribs (ceramic top that wraps the terminal associated with the cop plugs)
By lengthening the surface between the high voltage terminal and the grounded metal case of the spark plug, the physical shape of the rib provide functionality to improve the electrical insulation and prevent electrical energy leakage along the surface of the insulator of terminal metal case.
insulator tip
The end insulator that goes into the engine combustion chamber, supposedly able to withstand high temperatures and maintain the electrical insulation. To prevent overheating electrodes, then this section should have good thermal conductivity.
seals
Prevent leaks from the engine combustion chamber
metal case
Binding and channel the heat from the insulator to the cylinder cop, also serves as a ground for the spark through the center electrode to the side electrode.
Center electrode
Connected to the terminal via a cable initernal and ceramic resistance to reduce emission of radio interference resulting from the ignition. Its tip can be made of a combination of copper, chromium or nickel-iron metal of high value. And side electrode or grounding electrode made of nickel steel and at the soldered side Meral case.
