Not entirely wrong.
Step 1:
Cylinder 1 Intake
Cylinder 1 Exhaust
Cylinder 3 Exhaust
Cylinder 4 Intake

Step 2:
Cylinder 2 Intake
Cylinder 2 Exhaust
Cylinder 3 Intake
Cylinder 4 Exhaust

Rotate the engine 360 degrees between step1 and step 2. Valves in step 1 will be closed (rockers loose) so you can adjust them. After rotation, the valves in step 2 will be closed (rockers loose).

I worked in a motorcycle shop for years and an older experienced mechanic showed me this trick to adjust valves making sure they were always end up adjusted on the cam base circle.

1. Only work on one cyl at a time
2. Remove plugs (at this dealer we always replaced plugs)

Turn engine over (hand crank or starter bump)

Now here is the secret
Turn the engine over
When the exhaust valve starts to open adjust the intake valve
Rotate the engine over
When the intake valve starts to close adjust the exhaust valve
Repeat for other cylinders
The valves are adjusted on the cam base circle

Happy motoring

Just checked and adjusted the valves on my '81 Interstate. These instructions were excellent, thank you.
All of the intakes were good; 3 on the exhaust side were a little tight, about 0.10 mm. a 1/8 turn was about all I needed to get them each to 0.13 mm.

Do I have to drain the oil before I start this? How much oil comes out? Just did an oil changed before deciding to change the timing belts

You don't have to change the oil. Only a little will dribble out with the valve covers off. But it's a good time to do it. Just don't excessively spin the engine over when adjusting the valves. Maybe better to crank engine over by hand. Either by hand rotating the rear wheel (in highest gear) or using the alternator bolt. Or by carefully bumping it over with the starter.

I always did mine along with a tune up so oil and plugs were out. A good job to do in the morning with a cup of coffee. Relax and take your time. Don't hurry or force anything and you're gonna be fine. Buy yourself a genuine Honda service manual and read it.

When I worked on my race car I took notes of what it took (tools & procedures) and this would remind me of things that needed to be done. I have a notebook with these notes in my toolbox.

Good luck and have fun
Scott

The movement is just checking that you do in fact have the engine in the correct part of the cycle - you don't want to adjust valve clearance on a valve that is currently being compressed. Once you adjust all of the valves, the amount of movement will be correct.
