MXS 70cc cylinder kit Prebug Minarelli Vertical 10mm wrist pin

$ 169.00

70cc Cylinder Kit 'MXS Sport' Yamaha Zuma Prebug MBK Booster / Stunt (10mm piston pin) - developed by Maxiscoot's Racing Team!

The Nikasil-plated aluminium cylinder has 5 transfer ports and an oval exhaust port. The kit comes with a HQ single-ring piston (10mm wrist pin) and a high-compression cylinder head (port timings: 189.4°/123.6°/125.8°).

To unlock the full potential of this kit, we recommend running it with a 21mm (at least 17.5mm) carburetor and a sports exhaust (such as the Yasuni R); you can even run it with your original exhaust.

With the right set-up and adjustments, this sports kit can reach record-breaking 16hp!

The kit comes with complete piston (pin, circlips and ring included) and the proper gaskets for mounting. To make sure to get maximum power and reliability out of this cylinder kit, you should definitely adjust squish clearance when mounting it (cylinder spacers are included).

For: Minarelli Vertical engines
Diameter: 47.6mm - Stroke: 39mm
Note: piston pin = 10mm.
