Its a direct bolt on..You are going to take the reeds out of the package exactly how they come( the larger reed is on the bottom and the smaller "carbon" reed sits on top, your going to place them on the reed cage and place the ree flap ( the metal plate ) over the reeds and screw them in place..Make sure they are center.. Its really easy. Also make sure you intake boot is clean..and be carefull not to get dirt in your carb when you remove it..
