The cam contact surface on all screw adjuster type Suzuki rocker arms is a soft material covered with hard chrome. Under the increased loads of higher spring pressures, cam lifts, etc. the surface caves in allowing the chrome to crack and peel off. This wipes out the rocker and cam lobe.The solution is welding the contact pads with special hard face rod and regrinding the faces. This service is performed on customer supplied rockers. Note that they can have pad damage.Remove the adjuster screws. WE DO NOT RETURN ANY ADJUSTER SCREWS.
Some high lift applications require extended pads to keep lobe from running off the pad.Some builders use GSXR rockers in GS motors to change geometry.Only GS cores for GS rockers and GXXR for GSXRs.New rocker arms available.
*Adjuster Screws*
Some very high lift cams have reduced base circles to keep the nose of the cam on the rocker pad. This can cause a problem with the valve adjuster screws being too short to get proper valve lash. Theser high performance screws are longer than Suzuki screws and solve the problem.
