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

The Airsal 70cc Aluminium "Racing" Cylinder Kit MBK Booster / Stunt is mostly identical to the T6, but is now available with a piston by Mahle. Even without any additional porting, the cylinder has quite a bit of power, also thanks to the bridge exhaust that improves flow. Combining it with a bigger carb, a racing exhaust and maybe a little work on the exhaust port will get you appr. 10hp.

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