What is the model number of a 110 motorcycle spark plug?
3 Answers
For 110 motorcycles, there are two most common types of spark plugs: One has a thread diameter of 10 millimeters and a thread length of 12.7 millimeters. The other also has a thread diameter of 10 millimeters, but with a thread length of 19 millimeters. The function of a spark plug is to generate a high-voltage electric spark to ignite the compressed combustible air-fuel mixture. It ensures the normal operation of the engine, and without it, the vehicle cannot start. If the spark plug is well-maintained, the vehicle will be very fuel-efficient, quiet, and free of noise, which is very beneficial for motorcycles. Spark plug maintenance precautions: Always keep the spark plug insulator clean and dry. During normal use, dust, oil, and other deposits often accumulate on the spark plug insulator. These deposits can form external leakage paths, affecting the normal sparking of the plug. When servicing the engine or performing other operations, be careful not to bump the spark plug insulator to avoid damage from force, which could affect the spark plug's normal operation. When connecting or disconnecting the high-voltage wire, be cautious and gentle. Avoid excessive force or shaking the spark plug insulator to prevent damaging the spark plug's seal or causing it to fail. Do not drop or throw new spark plugs or those removed for cleaning and inspection to avoid damaging the insulator.
I've worked in a motorcycle repair shop for ten years. Common spark plug models for 110cc motorcycles include NGK CR7HSA or C7HSA, but this isn't absolute. The actual model depends on your bike brand - for example, Honda and Suzuki use different specifications. I've encountered too many customers who bought wrong spark plugs and ended up with delayed ignition and skyrocketing fuel consumption. The best advice is to check your owner's manual for factory recommendations or unscrew the old spark plug to check the number at the bottom. When replacing it yourself, use a spark plug wrench and turn gently to avoid breaking the threads. Check and clean carbon deposits every 10,000 km to prevent engine shaking issues. Always buy new spark plugs from authorized stores to avoid counterfeit risks.
My friends and I often ride 110cc motorcycles for outings. Choosing NGK C7HSA spark plugs is the safest bet, but it depends on the vehicle condition. My bike runs much smoother since I replaced it last year. The model number is easy to read on the old spark plug - mismatched ones may cause cold start difficulties. Just tell the parts shop your bike model and they'll find it for you, costing just a few dozen yuan. I recommend checking it every six months to avoid roadside breakdowns. Cleaning spark plugs is simple too - just spray some cleaner and wipe. DIY saves money. Using wrong models reduces power and increases fuel consumption, so remember to replace them promptly.
