SA-S-750 (GSXR-600 & GSXR-750) Early SA-S-1300 (GSX1300 R)
The GSXR has a ball bearing behind each cam sprocket. Press the original sprocket off but leave the bearing on. You’ll notice that a line has been stamped on the end of each camshaft at the factory. Line up one of the adapter’s 6mm threaded holes with the line and press the adapter on. Caution: make sure you press the adapter on the right way (with the larger of the two steps facing outwards). Make sure you are pressing the adapter on squarely to the cam. When pressing on an adapter, support the camshaft securely and squarely by the flange behind the ball bearing. DO NOT just stand the cam on its end and press. Failure to do this will result in damage to the cam and the adapter. You may want to slightly G.T.A.W. weld a spot or two to secure the adapter to the cam. This will insure no future movement. DO NOT OVERWELOl
