Tuning Big Valve intake kit from Easyboost for Minarelli upright engines. The kit comes with 2 metal spacers, matching Big Valve reed block for proper air flow and a set of gaskets. The Big Valve intake significantly increases the air-fuel flow and thus the cylinder filling, which has a noticeable positive effect on the throttle response and engine performance. Our recommendation: a larger intake manifold and carburettor round out this tuning level! Delivery includes:

2x spacer

3x gasket (paper)

4x bolt

1x reed block
