Part become very rare, here is a kit for engines ZUNDAPP 4M, 5M, FALCONET, RACING and many other models. This high performance kit from ATHENA is very robust and powerful! It consists of a nickel-treated aluminum cylinder EUROCILINDRO, a single-segment vertex piston! The diagrams, the compression ratio, the ducts ... Everything is studied to obtain an excellent engine performance. It is clearly less torque and powerful than the 70cc version, but it allows less soliciter crankshaft and respect the displacement of 50cc. It mounts in combination with the original breech! We recommend a 17.5 to 21mm carburetor and a sport exhaust!
