Removing the Rocker Cover, Camshaft, Cylinder Head, Cylinder, and Piston

Perform the following, preliminary steps.

Remove the fuel tank.
Drain the coolant.
Remove the radiator hoses from the cylinder head and water pump.
Remove both radiators from the frame.
Remove the exhaust header.
Remove the perimeter engine bracket.
Remove the entire engine from the frame of the motorcycle.

Set the crankshaft to TDC on the compression stroke, which will release pressure on the rockers and all four valves. Remove the two plug bolts from the cylinder head to verify the camshaft is in the proper position.
