What may be inappropriate or a bad ignition plugs make for Jawas pioneer? Candle with low heat value of the electrode to glow and then a detonation engine has a piston begins to knock. Indeed, in turn candle with high thermal value often pollutes and is sooty and oily. Oiled plug causes misfiring engine operation, the spark is irregular or the engine can not be started or stopped completely while driving.

The cause of oily or zakarbonování candle is commonly misaligned or improperly elected carburetor heat value of the spark plug. Contaminated candles should be thoroughly cleaned. When large electrode formed similar disorders as in oily candle. When a short circuit between the electrodes or insulation failure candles engine is not possible to shoot. The occurrence of these disorders are driving stops.

I know that most of you have been passionate about mechanics, but sometimes there may be situations when you would quite like to find out what your pioneer angry. However, there are ways to detect some problems very easily. Many of you might be surprised, but very good indicator of a problem with the engine's spark plug.

Because access and removing the spark plug handle most nearly everyone, let's look at how you can detect some defects mere visual inspection of the surface of the electrodes. How to look like a spark plug when the engine functions in order. Electrodes are tanned, insulator has a light brick color.

Secondly, candle is at the surface of the insulator are mainly red-colored deposit. This fact in itself is not a problem and can be caused by someone adds an additive to gasoline.

Third. Detonation combustion caused by low octane value of fuel or too early can damage the candle mechanically. Chipped insulator pieces, damage or loss of material especially large internal electrodes, all this should put you on this issue be highlighted.

Fourth. If the electrodes are wet and blackened, the most likely causes may be too rich mixture, irregularities in the ignition or improper heat value of the spark plug. It is too cold and needs to be replaced.

Fifthly. Candle, which crossed the interval required for the exchange, is generally decrepit. Tanned electrodes and the amount of deposits is a clear signal to the exchange. If you fail to do so, the engine does not have the necessary power and increases fuel consumption.

For the sixth. Too much carbon indicate improper heat value of the spark plug. Because it is too cold there is a deposition of unburnt residues and thus the deterioration of function. It must be done in exchange for warmer.

For the seventh. Too "hot plug" a major advance primarily causes melting of the outer electrode. Another reason may be too lean mixture and thus a high combustion temperature, which results also damage Spark.

After eight. Penetrating oil around leaky or broken piston rings, oil seals, gaskets or cause the formation of deposits on the electrode surface. This helps only overhaul the engine.

Ninth. Mechanical damage is caused by a defect in either the engine or ingestion of foreign bodies. Perhaps also a piece of a broken piston ring. In both cases it is necessary to carry out another inspection engine to avoid far greater damage.

I suppose that many of you will wonder what you can do in quotes ordinary candle. And it's not as I describe here Jawa Pioneer is also a motorbike higher classes. But it is a very important part of the reliability of the engine so that the engine has trod as to your liking. Note underestimate the right choice and the temperature of your candles I myself that I follow, and their candles really devote a lot of attention. Do not leave it until the last minute. Or a speech that the candle that is good I have it there for five years and carcass goes well, be generous in their candlelit not so big money but it can change and be a little big money. And really watch what you are buying candles, which heat values and at what time of year you go to these candles. Health Maxi dog. 'Nuff said I'm done talking.

That is why when I try to describe something here to give all my comments and photos to your idea. I also hope that those photos are outside the spinal cord comments useful and sometimes amusing. I wish all of you let those your pets trample and runs without problems. Health Maxi dog.

My advice to the conclusion reads. Check your candles underestimate even such a seemingly small but very important matter such as candles of your bike. Did you know that the frequency of ignitions up to 4,000 times per minute. Follow the rules of candles marking the seasons. That it is only a fraction of the components of your bike so you always and reliably serve you without any problems brought safely to your destination.
