Raise crankshaft cylinder 85mm Polini

Crankshaft cylinder riser 85mm Polini. From the Italian manufacturer Polini, we have this spacer, necessary when replacing your 80mm connecting rod crankshaft with an 85mm one. With this spacer, we will increase the cylinder height by 5mm so that it can function properly. It is delivered in a kit along with the new studs that you will need. Suitable for Minarelli horizontal cylinders from Polini.
