Stage 1 : increases torque and power with no additional modifications. Ideal for basic tuning. Stage 2 : better suited to large machines, requires further improvements such as hi-compression pistons and larger carburetor to deliver its potential. Stage 3 : specifically developed for Supermotard or to increase cylinders (use original valve springs for mounting) In any case, we strongly advise these preparations to be handled by qualified professionals and with the adapted tools. Two sets of valve discs included for a perfect fit.
