3-Installation of valves between axis DERBI or MINARELLI AM6 (with a small retouch), you will be able to install simple valves like the MALOSSI VL6, VL14, VL18 ... But we strongly recommend the valves TOP PERFORMANCES VFORCE of MINARELLI AM6, with a slight retouching holes, they have the right length and perfect dimmensions. They follow with a carburetor up to 30mm, with their roof system, they offer at all speeds a maximum of performance, with these, it is necessary to provide a small touch of the top of the housing to release the high blade!
