MXS Big Valve Minarelli Vertical / Zuma Prebug Intake

This Big Valve HighFlow kit is the result of many months of development and testing in our MXS Racing workshop; it is basically designed for use with our MXS MXS Racing and MXS Sport cylinders for Minarelli vertical. The intake is a little larger than other existing "Big Valve" intakes so it can easily be combined with MXS cylinders, and a reed valve for Minarelli AM6 engines can be mounted. You can, however, use it with any other cylinder for Minarelli vertical. The kit includes: rubber intake manifold d=32 / 35mm (PWK type) anodized green aluminium mount Allen screws (x8) aluminium spacer 1.5mm paper gasket (x1) hose clamp instruction manual For maximum performance and more torque, we recommend adding a V-Force 8 petal reed valve; minor modifications to the reed valve will be necessary.
