Airsal Cylinder Kit "T6" 70cc aluminium Yamaha BW's / Slider

A 70cc Aluminium Cylinder for a very good price, here at Maxiscoot! The Airsal 70cc Aluminium Cylinder Kit "T6" Yamaha BW's / Slider / MBK Booster / Stunt (Minarelli vertical, 10mm) is an excellent value for money for Minarelli engines.

The twin exhaust port is bridged and the piston is a single-ring piston, 10mm pin. We did test runs on our scooters with very convincing results. Its only shortcoming - the piston skirt's edges are a little rough. We recommend smoothing them with fine grade sandpaper.

Performance: between 8 and 10hp. We recommend a 17.5mm carburetor (minimum) to get the most out of this cylinder.

Please note that you'll have to adjust squish clearance when installing aluminium cylinders to get maximum power and reliability.
