Can anyone provide a Service Manual pdf link that works? Also, can anyone provide a list/location of all the sensors on this '98 Centauro ?

The issue is present regardless of engine temperature. The engine is equipped with an oil temperature gauge.

Thanks, everyone, for the variety of ideas. Mine is a '98 model year and shows 7600 miles. It has apparently had this problem for a long time, hence the mileage. It has the Joe Caruso gears recently installed and new cam belts. The spark plugs are new but not the wires. pete roper, it feels like sudden spark drop-out to me as well. I'll change out the plug wires, check the connections to the coils, and double up on the ground connections directly from the battery. guzzigary, is there a way to test the crank position sensor?

A little information..... I have owned a number of V 11 MG in my time, but never have I had this much trouble tuning one like I am with this Centauro. I have completed the usual tuning sequence, and replaced the TPS with a known good unit from another bike. With weather cooperating today, I went out on a road test and discovered the followin: 1. Idle is good once warm. The "choke" function works properly while cold. 2. Cruising under light throttle AND below 2000 rpm, the engine runs smoothly at any speed. 3. Accellerating from a stop or from any rolling speed or throttle opening is smooth and as powerful as expected. 4. Steady state cruising above 2000-2500 rpm through 4500 (that's as far as I dared go) precipitates extremely rough runnin, and I mean birdering on violent, at any speed in any gear. To me, the common issue is engine load/throttle position. This critically includes engine rpm (over 2000 rpm). I thought this pointed to the TPS but a new one had no effect on any of this. Conversation with Will Creedon suggested enrichening the ECU potentiometer setting. I found that ¼ turn increments, all the way to full rich did not positively affect the issue. (The last 90* of the available 180*, negatively affected idle and low speed running.) Does this information stimulate anyone's diagnostic ideas?

Is there current contact information for Will Creedon? I may have one of his chips installed and have some questions.

Sump flange for early V11 engines. May also fit other years as part number is specific for the paint variant. MSRP $315 USD make an offer.

Harper's has the "bumper" pads but not the metal mounting "plates". I think that I can make the plates using the pads as templates.

Upon making inquiry with AF1 Racing, a Texas motorcycle dealership very conversant on things Moto Guzzi, they provided me with a copy of the attached OEM parts fiche which provides the information that I referenced above. Clearly, there are parts that I need to acquire. I provide this for the forum's information.

Having just received a bare OEM luggage rack for my Centauro, and having received no mounting hardware along with it, I am stymied about the mounting process. It seems that either the missing hardware is a crucial component of the unit, or that this unit is not correct for my Centauro. Can someone illuminate this conundrum for me as I cannot find anything at the usual interweb resources.

Perfect! Thank you. This is exactly what I was looking for. I have found it available through a Canadian distributor and have ordered it through the local retailer. I'll post pictures of the fitment.

It's the " vintage" thing that appears to be the problem. Do you know if the Tuono one would fit?

Indeed, but they have nothing in a tank mount ring that is undrilled, so I have ordered a tail bag mount which I will cut to fit, I hope.🤪

As noted by others, Curtis was responsive to the phone call, once he was reached. Issue resolved!

I have a V11 upper sump half if you decide to go in that direction.
