Charles, here is the adj procedure according to Dave Dodge. From what I have heard this is the way to do it. I need to do this myself.
A) Remove all of the spark plugs and left side alternator cover.
Rotate the engine at the crank nut (alternator) in a clockwise rotation (only) while putting your finger tightly over the #1 plug hole (left rear). When the engine begins compression stroke on #1 you will feel pressure against your finger. Once you begin to feel pressure, slowly rotate crank to align "T-1" index mark of the rotor with the case half alignment position. This is your starting point at cylinder #1
NOTE: The cam lobes on the rear cylinders Will point away from each other at TDC compression. The cam lobes on the front cylinders will point up and slightly towards each other when timing marks are aligned The marks on the cam sprockets will also line up with the gasket surface on the head when the cams are in the correct Inca f/on.
C) I personally do not use the factory Honda tool. I instead (beginning with #1, lobes pointing away from each other) insert a .003" feeler gauge between the cam lobe and rocker arm pad. I then turn the adjusting screws until they lightly touch the ends of the valves and tighten the lock nuts. This method will give you a snug .003" clearance at the cam, and .005" clearance at the valve. The recommended .004" at the valve is too tight.
D) Slowly rotate crank (clockwise from #1) with finger over #2 plug hole until 'T" rotor mark aligns with case mark. You should have felt the pressure against your finger. The lobes will be pointing up and slightly towards each other and the cam sprocket marks aligned with head surface. Adjust valves.
E) Slowly rotate crank to #3 cylinder and follow alignment procedure "C"
F) Slowly rotate crank to #4 cylinder and follow alignment procedure "D"
NOTE: After adjusting each cylinder check for proper clearance at each valve. After adjusting all of the valves, rotate engine for a couple revolutions and recheck all clearances again at TOO locations (just to make sure). When you are satisfied that all clearances are set, the locknuts must be torqued to 14 ft. lbs.
Because you are adjusting the valves at the location where the clearance would be the loosest, there is really no way to get them too tight.
