Our very own MXS Racing Intake Kit Big Valve w/ HighFlow System Yamaha BW's, available for a very good price.

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 3i reed valve; minor modifications to the reed valve will be necessary.
