Cylinders from UNI AUTO with Stage4 specification. Cast directly with larger channel surfaces. The cylinder casting is very hard.
The cylinder is recommended as a stable touring cylinder. This means that the cylinder can be used sensibly with carburetor sizes of 20-30 mm.
You can build a fast touring engine with a 30 mm carburetor and the bgm Big Box Clubman exhaust. Depending on the gearbox and your personal taste, the gear ratio should be between 5.22 and 4.80.AI-translation
