I don't know how anyone else does this job, but I remove the spark plugs, and turn the engine over with the allen head bolt that secures the alternator rotor, and if you do this, you need to remove the ground cable from the battery, as there are 'hot' terminals under the front cover, and if you touch the front cover to one of these, good chance you'll fry the diode board .
Valve clearance check/adjustment, needs to be done on a 'cold' engine .
Checking the cylinder head hold down nuts for proper torque, is a good idea, before performing the valve adjustment .
