Description
Cylinder Kit d.46mm Airsal Racing 70cc Puch Maxi, racing cylinder for Puch Maxi. The cylinder is made of aluminium with excellent cooling properties, the cylinder bore is Nikasil-coated and thus very durable.
70cc displacement is quite a bit, and even better: the crankcase does not have to be modified / milled for this kit! The cylinder shows its full potential at mid-range where it will get you extremely strong torque, and the cylinder is powerful and reliable at high rpm as well.
An excellently machined cylinder head is included in the kit, as well as a 1-ring piston and gaskets. It is a high-compression head (HC) for excellent performance. The cylinder has an oval inlet, 4 transfer ports (128°) and an oval outlet (175°).
We recommend a larger carburetor and a performance-optimising sports exhaust.
By the way, the cylinder is also available separately without cylinder head!

How to Install a cylinder on a scooter, motorcycle or moped
The cylinder or cylinder kit is the heart of the engine on scooters, motorcycles and mopeds. It consists of a cylinder, a piston with piston ring(s), a cylinder head and gaskets needed for installation.
The service life of a cylinder depends on whether it has been fitted correctly.
Tuning Level: Racing
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
Aluminium cylinders
Aluminium cylinders are more powerful than cast iron cylinders, but require more regular maintenance and must be combined with different components such as a reinforced crankshaft and a larger carburetor.
How to run in an aluminium cylinder?
Aluminium cylinders should be run in for about 200 kilometers , and you should use a fully synthetic engine oil.
Note: To ensure optimum performance and reliability, it is advisable to measure the squish clearance. Just have a look at our tutorial How to adjust squish clearance.
