TPS slightly in one direction will increase the voltage; turning it in the other direction

will decrease the voltage. Turn the TPS until the observed voltage decreases to about

.006 or .005 volts, which probably is as low as the voltage will go. If it will go no lower,

that's okay. DO NOT continue to turn the TPS after it reaches its minimum value,

which is close to zero. Start at a high value (.300) and turn the TPS until it reaches the

low value (.006 or .005) and stop. [Note: Some digital voltmeters have an autorange

function; below a certain value they will read in millivolts. The .006 may read as 6 MV,

which is the same as .006 volts. Don't let the decimal places confuse you.]

Stop moving the TPS just when the voltage stops decreasing and lock it down there.

At this point we say the TPS is at zero. The throttle position is also at zero. The TPS is

now locked and set. This is the last TPS adjustment you will need; it is now set. You

will not change the position of the TPS again !! [Author's note: The throttle opening is

at zero and the TPS value is at zero, which explains Rob Lentini's title of "Zero-Zero"

for this procedure.]

Step 6. Move left throttle plate stop screw to obtain .370 volts and lock screw.

With the ignition still on, turn the left throttle plate stop screw clockwise (CW). By

turning the screw, the flange will be moved away from the throttle plate. Continue

turning the throttle plate stop screw until the voltage starts to rise, and continue until

you reach 370 millivolts (.370 volts). Stop there, and lock it down with the lock nut. Blip

the throttle several times to check the accuracy and repeatability of the 370 millivolts.

Readjust the throttle plate screw if necessary. Remove the DVM, remove the object

inserted into wire #1, replace the rubber boot onto the TPS.

There is a possibility that .370 millivolts will not be the correct adjustment value for your

bike. This will be explained in Step 10.

Step 7. Large brass bypass screws in, bike on, warm engine, rough idle expected

On the right side of the bike, on the outer surface of the throttle body tube, is a large

brass bypass screw with a slotted (NOT Phillips) head that faces toward the rear of the

bike. If you were to place a screwdriver on the screw, the handle of the screwdriver

would point toward the right rear turn signal. This large brass bypass screw is

approximately one inch forward of the black plastic air intake tube. You are looking for it

on the right side because it is easier to locate there; there are fewer things in the way.

You can see the large brass bypass screws easily when standing near the turn signals.

If you look on the left side, you will find a similar large brass bypass screw. The official

BMW Repair Manual calls this a "recirculating air screw" at page 00.27.

Count and record the turns you make to lightly seat both the right and left large brass

bypass screws by turning them clockwise with a flat screwdriver.

Position a fan near the front tire with its output directed at the cylinders equally to avoid

overheating, or use two fans, one directed to each cylinder. If your bike has a Rider

Information Display (RID), allow the oil to heat up to 5 bars, otherwise idle the bike for

five minutes. It will idle rough because it is not in synch. Do not be concerned about a

rough idle at this time.
