hi guys, i have a question about the vf3 reed valve system i just bought. thier is two pieces with the kit on is the reed cage and reeds, but the other piece looks like it fits in the carb side of the reed cage. i have a 35mm pwk keihin carb and was wondering if that piece needed to be in the reed cage or not. i believe it is a custom air guide but i dont know if i need it in their or not.
