Valve Adjustment - Stephen Karlan (Dali Meeow)

TOOLS NEEDED

newspaper (oil catcher) flashlight drain pan

med. screwdriver (pry) 3, 4, 5, 6 mm T handle Allen plug tool

compressed air torque wrench 2 sets gauges

hemostat for rubber plug 10mm box wrench carb stix

5/8-in. or 17mm socket pliers

You must start with a cold engine. Put newspaper or drain pan under the cylinder heads to

catch the oil drips. Remove alternator cover using 4mm Allen wrench. Check alternator belt for

cracks and tension and then leave cover off for valve adjustment.

Remove round black rubber timing hole plug (size of quarter) located on right side of engine

(above and to the rear of the cylinder head) by grabbing the edge of the plug with a hemostat

(medical tweezers, marijuana roach holder) and pulling or carefully pry it out with a long

screwdriver. Timing marks will be seen inside of this hole later on during the adjustment

procedure.

Remove black plastic strip ("4 Valve" imprinted on part) covering the spark plug by hand.

Remove plug wire from plug by using 2-inch long black plastic loop tool contained in your

BMW tool kit. The purpose of the black plastic loop tool is to give you a handle to pull on that

will pull the plug wire off the plug. Holding onto the loop end, point open side toward rear of

bike while hooking the tool onto the plug wire boot, then pull out to remove the plug wire. Use

compressed air to blow out plug hole before removing plug -- there will be dirt in that hole that

you don't want in your cylinder !! At the very least, use a tube or straw to direct the air and lots

of lung force. Remove spark plug using tool kit wrench. Place a pan/newspaper under the

valve cover to catch the small amount of oil that will drip out when you loosen the four valve

cover Allen screws. Loosen the Allen screws with a 6mm wrench and remove the valve cover;

lightly tap if it's stuck.

With bike on centerstand and in neutral, use appropriate socket (5/8-in. or 17mm, depending

on bike) to turn the lower alternator drive pulley (and engine) clockwise. Insert long

screwdriver into either spark plug hole while turning engine over; when screwdriver is being

pushed out, start looking for timing marks. Use a small flashlight to illuminate the flywheel

marks. The marks, in order, are "Z", "S" and "OT". Center "OT" in the timing hole opening.

Optional method #1 for moving the cylinders into place: Instead of looking at the flywheel

index marks, remove both spark plugs and put the bike on the center stand in 5th gear. Put a

long screwdriver into either spark plug hole and push it against the piston crown. Rotate the

rear wheel until the screwdriver projects the maximum distance out of the cylinder. Rock the

engine by moving the rear wheel slightly back and forth to get the piston at the very top, OT.

With OT centered, the valves on one side of the engine will "wiggle" a little bit. If they do not

"wiggle", check the valves on the opposite side of the engine. One side or the other must

wiggle. Adjust valves using 10 mm box wrench, 3mm Allen and two feeler gauges.

BMW recommends the following two feeler gauge dance step. One gauge is used to adjust the

intake (or exhaust) valve while the second feeler gauge is positioned under the adjoining

intake (or exhaust) valve to stabilize and prevent the rocker from canting.
