When servicing a scooter, it is necessary to unscrew the scooter's spark plug to determine whether the carburetor is set correctly.
It is important to pay attention to the brand and heat rating of the spark plug - if you install a spark plug with a different heat rating from the recommended one, it will not self-clean. If the candle is whitish, you need to enrich the mixture; if it is black, lean it. The adjustment is made on the scooter's carburetor with a special screw located under the cover covering the accelerator drive rocker arm. It is important to remember that a scooter air filter clogged with dirt, without passing the required amount of air, will cause the mixture to become richer, and before drawing conclusions about the need to adjust the scooter carburetor, it is necessary to check the condition of the air filter. A correctly selected scooter spark plug has a decisive influence on the performance of the scooter, as well as on its temperature regime. A spark plug with the heat rating recommended by the manufacturer should be installed on the engine only; only in this case will the process of self-cleaning from carbon deposits occur. The spark plug is a comprehensive source of information for deciding on the necessary repair procedures. This method is used to repair both scooters and cars, such as Ford repairs.
It must be remembered that the reason for the enrichment of the scooter mixture can be not only incorrect carburetor settings, but also a dirty scooter air filter; and the cause of a lean mixture may be the scooter’s fuel system clogged with dirt.
Soot contamination
Type of spark plug: dry soft soot of intense black color on the insulator, electrodes and spark plug body.
Consequences: poor start of the scooter engine; poor operation of a cold scooter engine; interruptions in ignition of the air-fuel mixture; bad reaction to gas.
Probable causes: excessively rich air-fuel mixture; The scooter's air filter is very clogged; The thermal range is incorrectly selected - the candle is too “cold”.
Remedy: adjust the working mixture; adjust the cold start system of the scooter engine; change the scooter air filter; clean the spark plugs or replace them with new ones - with the correct heat rating.

Overheat.
Plug Type: Extremely white insulator with small black flecks and premature electrode erosion.
Consequences: loss of scooter power at high speed or under load.
Probable causes: the spark plug is not screwed in enough; The scooter's engine cooling system is not working properly; ignition of the scooter too early; The thermal range is incorrectly selected - the candle is too “hot”.
Remedy: check the torque of the scooter's spark plug; operation of the scooter engine cooling system; adjust the ignition timing; select the correct spark plug heat rating.
Type of spark plug: melted and burned central and grounding electrodes (or one of the electrodes) of the scooter spark plug; bubbling insulator with metal deposits on it.
Consequences: significant loss of scooter engine power; ignition interruptions. Continued use of such spark plugs may cause serious damage to the scooter engine.
Probable causes: thermal overload; significant overheating of spark plug parts due to glow ignition - combustion begins before a proper ignition spark appears; use of low-quality fuel; burning out of the remaining air-fuel mixture in the combustion chamber due to an incorrectly adjusted fuel system of the scooter or the ignition timing of the scooter; The thermal range is incorrectly selected - the spark plug is too “hot”.
Remedy: check the scooter engine, ignition system and fuel system, as well as the quality of the working mixture and the ignition timing of the scooter. Install new spark plugs with the correct heat rating.
Spark plug NGK BP6HS (HONDA DIO)
Signs of a faulty spark plug on a 2T engine. The quality of the photos is not very good, but you can still understand the main points from them. And so, we have 2 halves of the crankcase, a crankshaft, a Honda Dio spark plug, and a pair of main bearings.
Cleanliness is the key to health, so all parts, especially the crankcase, must first be thoroughly cleaned of all contaminants.
We wash the bearings from factory grease. Next, we heat the crankcase with a hair dryer. It needs to be heated well.
If you don’t have a hairdryer, you can use the oven. But in this case, you will have to change the silent blocks, and the kitchen will also be provided with an unforgettable aroma.
What are the best spark plugs for a Honda dio? Honda dio spark plugs
Bearings can be pre-frozen in the freezer. We put both bearings in their places.
If you have heated the crankcase well enough, the bearings can be put into place by hand easily and without effort. And then the fun begins. We take one half of the crankcase and the crankshaft. We insert the crankshaft into the crankcase half by hand as far as possible; there is no point in applying superhuman efforts at this stage.
Now you need to find some object to put on the crankshaft, a Honda Dio spark plug, with which you can press the crankshaft into the bearing. For example, this could be a tube of suitable length and diameter or a bunch of old bearings. We put this stuff on the crankshaft so that there is a thread left for the nut. Now, by tightening the nut, we tighten the crankshaft into the bearing.
Next, take the second half of the crankcase and apply thin to the Honda Dio spark plug! Next, we tighten the halves with bolts.
By this stage there should be no more gaps left, otherwise you risk bending the crankshaft. Honda Dio spark plug crankshaft needs to be centered.
For this you need a set of probes. And if you drive long distances, or with a heavy load, a cold spark plug with a heat rating of 7 or 8 is suitable to avoid hot ignition - after all, during intensive work the spark plug is prone to overheating. Exactly the same rule can be followed for seasonal use of a scooter. Not all scooter riders park their horse in the garage in winter.
If you continue to drive a Honda Dio spark plug in the cold, it makes sense to install a hotter spark plug.
And in the hot summer it will be correct to drive with a cold spark plug. By the type of candle you can conditionally determine whether the heat number is selected correctly. The normal color of the insulator should be light brown.
If the insulator is very light or even white, then the plug is too hot for a Honda Dio engine spark plug. I have a question, perhaps not significant, about candles.
or plays a big role. I couldn't find the answer myself. The bp6hs spark plug is not installed on any Japanese scooter. This candle is used by all the dealers selling Japanese scooters because it is very cheap to purchase and is made in China.
But the bpr6hs spark plug is installed at the factory in Japan on many scooter models. Draw your own conclusions whether the resistor plays a big role.
December 4th, in Spark plug for Honda Dio zx28 with 70cc piston engine, which spark plug to choose, it was ngk b8hs all covered in oil and misfiring. Please tell me the spark plug Honda Dio spark plugs for the Aprilia Scarabeo ie scooter. I have a Honda fullmark, please tell me which NGK spark plug is installed???
