Racing Crankshaft Jasil Full-Swing for Puch Maxi E50 (1-Speed)

Get the maximum performance out of your moped! The Jasil racing crankshaft in the full-swing design is the ultimate upgrade for any tuned Puch Maxi E50 engine. The closed swings significantly increase the pre-compression in the crankcase, leading to a noticeably improved cylinder filling. The result: Noticeably more torque and a higher top speed.

This crankshaft is designed not only for performance but also for extreme durability. It is finely balanced and easily withstands the high RPMs of racing cylinders. The reinforced connecting rod provides additional stability under heavy loads. Whether you're on the racetrack or optimizing your everyday moped for the mountains – this full-swing crankshaft is the heart of any serious tuning project.

Installation and Maintenance Tips

• Recommended bearing replacement: Always install new quality bearings (preferably C3 bearings) when fitting a racing crankshaft to ensure full power is safely and smoothly delivered to the road.

• Utilize pre-compression: Since the full-swing crankshaft reduces the dead space in the crankcase, make sure your carburetor and jetting are optimally tuned to this new pressure.

• Lubrication: Use only high-quality, fully synthetic two-stroke oil at a mixing ratio of 1:50 for a racing crankshaft to perfectly protect the connecting rod bearing even at maximum RPM.

• Set ignition: Be sure to check the ignition timing after installation. As the engine is now more responsive, precise ignition is crucial for cooling and performance.
