Surfer kris
The venturi step is known as a plenun chamber its purpose is to
Retain unused previous charge to the crankcase very useful as it happens
Around 350 times per secondplenum chambers were banned far fai speed
Events using 4 mm venturi many years ago but does not affect cox 049
In fact promotes easier tuning & more power
