AIRSAL Ø47mm liquid-cooled cylinder head for MBK 51 / Motobecane AV10

Here is the cylinder head to accompany your Ø47mm AIRSAL liquid-cooled cylinders on MBK 51.

This high-quality, one-piece cylinder head features a high-compression hemispherical combustion chamber with a polished finish. It requires a standard 0.5mm aluminum head gasket for the center (compression) and an original O-ring for the outer chamber.

A squish clearance of 0.9mm to 1.2mm is recommended for this setup. For high-mileage riders who want to maximize reliability, without a water pump, and who might use fuel of questionable quality, a 1.4mm squish clearance may be more appropriate!
