Let us know how you did.
Those instructions are fairly good, but there is one REALLY BIG
DO NOT remove the spark plugs before checking valve clearances!!!!!
This is a big NO-NO, and is spelled out in the BMW service manual. When removing the plugs small particles of carbon are dislodged, and may fall into any open exhaust valve, and when you rotate the engine to check each cylinder's valve clearances any particle resting on the valve face or seat will hold the valve open slightly, and you will get a larger clearance reading than you would with the valve closed, causing you to think the clearance is larger than it really is.
If you are just checking valves, or even adjusting them, there is no need to remove the plugs at all.
Also, at the end, he does not say that after you put the sprockets back on and have removed the tensioner hold back tool, the cams should be in the correct position if you did not turn the engine after removing them. To fully check this, remove number one spark plug, and with a small rod or dowel pushed against the top of the piston rotate the engine one revolution (by rocking the rear wheel in the forward travel direction with the transmission in 5th gear) until the piston is back on top dead center and re-check the flats on the rear of the cams. If they are perpindicular to the head, you are good to go. It will be very visible if you are off even one tooth on a sprocket.
