Our very own MXS Racing Intake Kit Big Valve w/ HighFlow System Yamaha BW's / Slider / MBK Booster / Nitro, 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 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. You can, however, use it with any other (Racing + Hyper racing) cylinder for Yamaha BW's / Slider etc.

This Big Valve HighFlow intake kit includes a Stage6 Reed Valve Viton AM6 / Derbi for optimum flow and cylinder filling - and, consequently, improved performance.

The kit includes:

• rubber intake manifold d=32 / 35mm (PWK type)
• anodized green aluminium mount
• Stage6 Reed Valve Viton AM6
• Allen screws (x8)
• aluminium spacer 1.5mm
• paper gasket (x1)
• hose clamp
• installation guide

Note: 1 gasket is included, but we recommend adding a paper gasket or silicone sealant (depending on your manifold).
