| + | These C-clamp pliers make a good tool to adjust the spring cam height if you don't have the proper spanner. The ends were ground to an angle using an angle grinder. \\ | ||
| + | Then you simply adjust the jaws to fit opposite holes in the cam with very light clamp pressure on the tool and turn the spring cam where you want it. \\ | ||

| + | The top acorn nut on a 98 1200S (probably other year models) is a 9/16" 6 sided hex nut. The threaded stud is welded to the frame. \\ | ||
| + | The lower mounting nut and bolt are both 3/4" six sided hex heads. The rear nut takes an open end wrench due to little room between the nut and frame. \\ | ||
