Gentlemen, I just might be from the old school on valve adjustments.
Some of you may follow what the "new books" says. There's the old way, and there's the new way, so to speak. I'll take the sure way, as it's the best way to insure proper valve clearance.
So here's two versions on how it can be done.
1) In written form... as you have stated in your posts here.
2) In a video form... the old way... the sure way.
Results: Probably come out the same on valve clearance.
Adjusting Overhead Valves the modern way according to John Deere's bible.
Turn the flywheel to close both valves.
Insert a narrow screwdriver into the spark plug hole and touch the piston. Turn the flywheel clockwise past top dead center until the piston has moved down 1/4". Use the screwdriver to gauge the piston's range of motion. PLEASE NOTE: This procedure must be performed for each cylinder on V-Twin engines.
Check the valve clearance by placing a feeler gauge between the valve head and the rocker arm. Clearances differ for the two valves and typically range from .002 - .004" to .005 - .007". Valve clearance specifications for your engine series are available by viewing our Engine Specifications Chart.
Adjust the clearances as required by turning the rocker screw. Once adjustments are completed, tighten the rocker nut.
Install the valve cover, using new gaskets, as required, and make sure the cover is secure.
The Old Way. Less headache and accurate.
