Basically, the ignition system must be capable of supplying the amount of voltage required to create a spark in the opening of the electrode. In practice, this means that there must be a considerable “reserve deignición” factors to take into account normal wear and spark plug ignition system. Book ignition, so … is the difference between the voltage available from the ignition system and the voltage required by the spark plug. Many factors can diminish the pool of fire “and cause loss of ejecución.Para that a spark plug to execute its core work of providing a high voltage at the appropriate point in the combustion chamber, it must comply exactly with the dimensional requirements of the cylinder in particularly when it is installed. Manufacturers generally use spark plugs with a diameter of threads on 8mm, 10mm and 12mm.
Note: The tolerance measures threads must meet the specifications set by the SAE (Society of Automotive Engineers) and ISO (International Standard Organization). The condition and quality of the spark plugs are very important for reliable performance in motorcycle engines. Offered in the market different types of designs to meet different and varied purposes that might require a motorcycle. Remember to always consult the manual of your motorcycle for the proper selection and values on specifications. Although the task of inspecting and change (s) spark plug (s) may sound a little intimidating at first instance, then a brief description of basic steps to make your next assignment. First, become familiar with the area to work, so it gives you an idea of how to make a much safer approach. Photo # 1 (0600) Make sure you have all the right tools to do the job (the sizes and variations of tools and accessories needed will depend on the make and model of the motorcycle). Photo # 2 (0646) Many motorcycles require the removal of the fuel tank and most likely the removal of the air induction system. Remove the main fuel supply (if applicable). Photo # 3 (0609) Remove the fuel tank. Photo # 4 (0618) Your next task will be to remove the “cover” of the spark plug, clean the area with a cloth, brush or air pressure to prevent any particles from falling into the cavity of the spark plug. Photo # 5 (0626) Carefully turn the cover until it releases from the spark plug. Photo # 6 (0628) In multi-cylinder engines, list the position of the cables. Motorcycle with the “cover” to the integrated coil, release the electrical connector, turn the release of the coil and spark plug. Proceed to inspect the “cover” for abrasions or fissures. Recommended lighting the spark plug cavity with a flashlight to inspect the possibility of a particle deposited on the inside, if any, to remove it using a vacuum or air pressure. Place the tool and proceed to remove the spark plug. Photo # 7 (0652) should not be completely loose nor very strong. Inspect the spark plug, Photo # 8 (0654) if necessary clean and refurbish or replace. Use a solvent (not gasoline), clean with a brush or wire brush (being careful not to hurt the ceramics). This process will remove any contaminants on the island. Photo # 9.10 (0662 and 0664) Remove the solvent with a clean cloth or air pressure. Check the opening of the electrode, the spark plug gauge according to manufacturing specifications. Photo # 11 (0672) When installing the spark plug is recommended that you use a type of “atiseize” below the tip (not applicable to the first thread or near the electrode). Insert the plug into the cavity, begins to tighten by hand only. Recommendations of the manufacturing conforms to generally apply the following twists: 8mm (6-7 ft-lb), 10mm (7-9 ft-lb), 12mm (11-14 ft-lb). Photo # 12 (0642) Note: When you are re-installing a spark plug used previously, where the washer is been compressed, the spark plug only needs to rotate ¼ turn after being adjusted manually. Replace the cover over the spark plug, make sure that strong as it could go a particle somewhere open. Photo # 13 (0685) Take the time to re-locate all the parts back into place. Remember connectors, clamps, etc.. Photo # 14.15 (0688 and 0691).
