Info
Will enlarging the cylinder (e.g. 125cc → 150cc) affect engine longevity?
A: Provided that specified components are matched and correctly installed, a larger cylinder will not significantly shorten service life. It is advisable to concurrently inspect the fuel injector/carburettor, ECU, crankshaft, etc., to ensure long-term stability.
What are the differences between aluminium alloy cylinders, ceramic cylinders, and cast iron cylinders?
A:
Aluminium alloy cylinders: Rapid heat dissipation and strong power output, suitable for daily use and modifications.
Ceramic (electroplated) cylinders: Superior wear resistance and robust power delivery, representing a premium choice.
Cast iron cylinders: Cost-effective and durable, though with average heat dissipation, making them more suitable for everyday commuting
How to choose a cylinder for your motorcycle?
Selecting a motorcycle cylinder requires comprehensive consideration of a number of factors, the following is a detailed selection guide:
First, suitable model and specification match. First of all, it is necessary to clarify the brand, model and year of the motorcycle. Different models have different engine and drivetrain designs and have different requirements for cylinder. Second, be sure to specify the size parameters such as the outer diameter, inner diameter and thickness of the cylinder.
What is brand of product do you sell?
We can provide Yamaha, Honda, Piaggio
How long does delivery take?
international delivery take around 15 to 20 working days
After replacing your cylinders, did you notice a significant improvement in power?
A: Replacing with the same displacement improves compression and sealing, resulting in smoother power delivery. Increasing displacement (e.g., 150→170) enhances acceleration and hill-climbing capability.
Will fuel consumption increase after replacing the cylinder?
A: If the displacement increases, fuel consumption may rise by approximately 5%-10%; replacing with the same displacement typically sees little change.
Does installing a new cylinder require modifying the ECU or carburettor?
A:
For an OEM replacement of the same displacement: No.
For an aftermarket upgrade to a larger displacement: It is advisable to recalibrate the ECU/carburettor fuel injection to ensure normal power output and temperature.
Does a new cylinder require running-in? How long should the running-in period be?
A: Yes, it does. We recommend running it in for 300–500 kilometres, during which time avoid heavy throttle use and prolonged high-rev operation.
What should be noted during the running-in period?
A:
1.Change engine oil frequently (every 100km/300km)
2.Avoid operating under full load
3.Do not allow the engine to idle at excessively low RPM
4.Check immediately if abnormal temperatures occur
