For the following V11 Moto Guzzi made from 1999-2006

V11 Le Mans, Rosso Mandello, Tenni, Cafe Sport, Corsa, Nero Corsa, Ballabio, and Coppa Italia.

If you the valves need adjusting, do first. Here is a link to good instructions:

Then make sure the TPS is to 150 mv at fully closed as follows:

the synchronization rod at the ball joint on the side (the side the TPS sensor),

back off the right idle screw using a hex key,

and back off the choke cam sure the choke cable full retraction of the cam (it didn’t on my

Turn on the ignition key, but do not the bike.

Measure the voltage between the two outer wires of the

If the voltage is not 150 mV �5 mV, then loosen the TPS screws and gently rotate it as

Be careful not to force it against the internal stop in the direction of the voltage, which could it.

Plus or minus 5 mV can be obtained a little effort.

To do the next you will need to connect a manometer (e.g. mercury to each of the two ports on the intake next to the cylinder head.

Next, close both air screws,

Screw in the left throttle screw if the idle is too low to maintain.

Do not use the for this purpose, because would put the connecting rod in compression, backlash, causing the throttle to go out of balance.

Now adjust the left screw for a TPS reading of .521 + — .005 (corresponding to 3.5 physical opening, as read by the diagnostic software).

This can be obtained with a little (Some riders have known to also subsequently readjust the TPS (not the idle to lean or richen the entire range. However, loosening its and offsetting the TPS to a higher voltage, 539, will fool the ECU adding more fuel, but it also fool the ignition table.

See also the note at the under �Options�)

Next both air bypass screws to the idle RPM at 1100 to 1200 maintaining balance.

Air bypass screws should be 1/2 turn or more.

If not, off the idle screw to reduce the TPS reading in steps of 15 mv and open the air screws to compensate until are opened 1/2 turn or more.

B. Check balance at idle If OK, go to step C, if not, rebalance at using the air bypass screws, and go to step A.

C. Disconnect the voltmeter and Replace the hose connecting the two

That completes the procedure.

this procedure is completed future minor changes in speed can be made simply by the left throttle idle Since the throttle bodies been balanced, backlash them has been eliminated, and air screws have been adjusted to maintain balance at these should be stable for miles.

Measure the TPS voltage at the two wires or TPS contacts. There are different methods:

1- Probe at the

2- Disconnect the cable connector the TPS. Use two short lengths of stranded wire of about 30 Strip about 1/4-3/8 off the ends of the stranded wires, a stripped end into the connector, and the connector in part way, far to make electrical connection, but no to jam it all the way.

3- Follow the wires up the seat, splice, solder, and in some lines with bullet connectors for easy

4- Probe at the TPS connector, as shown in image that Mike graciously provided:
