BOX A REED VALVE SCOOTER STAGE6 BIG VALVE FOR MBK 50 BOOSTER, STUNT/YAMAHA 50 BWS, SLIDER (FOR CARBURATEURS OF DIAMETER 12 A 28 mm)

Here we offer you the Stage6 BigValve intake system for vertical MBK Booster / Stunt Minarelli!

As you know, vertical engines are restricted at the intake level by a small diameter reed valve block. In order to be able to unclamp them, Stage6 has developed this Big Valve intake which allows you to accommodate a larger reed valve block in order to allow better filling of your engine crankcase.

A larger reed valve block gives you better filling of your engine, in concrete terms this brings a performance gain, particularly at high revs.

Delivery contains:

An aluminum base
A Stage6 reed valve block
An aluminum pipe with vacuum connection
A D.24mm rubber connector (12 to 21mm carburetors)
an aluminum fitting with sleeve for large carburetors (e.g. Stage 6 PWK, Koso, Mikuni, MRD, etc.)
A paper seal
