Metric Flow Balls
Our metric flow ball kit contains eight precision balls 2mm to 9mm welded to stainless steel rods. The metric kit is designed for small engines with port sizes up to 32mm (1 1/4” inches), carburetor work or any small passageway you may want to investigate. The 2mm ball is welded to a .035” dia. rod.
These tools will enable you to insightfully do research and design work and “map” your cylinder head port.
Since you can’t see air, you can put these tools in the port, watch and measure changes, and the magnitude of those changes.
Custom sizes and lengths are also available. Just contact us!
