I have read an article from AMSOIL that states too much ZDDP is not "better"; quite the contrary in fact, since they state it can damage your engine. Here below is an excerpt from the recommended fluids for the V11 Le Mans. As you can see, it is in line with whatever Oil manufacturers recommend 5W-40. But as with everything else, this recommendation is frozen in time. Interestingly, AGIP is now ENI, and they have a new oil line using the i-Ride prefix. They no longer offer Agip Racing; the only place you find racing is in oil specifically conceived for Aprilia: i-Ride Aprilia Racing in SAE grades: 10W60 and 5W40. Those are indicated as "racing" lubricants. For us V11 owners, I think the i-Ride 20W50 is what they would recommend. As you would expect, they only show the usual SAE parameters.

AMSOIL also advertises they use anti-wear components in the recommended oil for our V11s; https://www.amsoil.com/lookup/motorcycle/2004/moto-guzzi/v11-sport-v11-lemans/1100/?volume=us-volume

I know UK can be cold, but I would not think you need 0W -35 degrees Celcius would be exceptional. If I check the Castrol UK website, they recommend the usual 5W40 which is typical of all the sites I checked. In their spec sheet, they only state the SAE parameters. Here's the link: https://www.castrol.com/en_gb/united-kingdom/home/car-engine-oil-and-fluids/motor-oil-and-fluids-finder.html?customerType=retail&category=motorcycles-mopeds-atv-utv&make=moto-guzzi&model=v-series-1977-&engineType=v-11-1998-2006&ref=954f0940624f1d950b784a0852e063d5&component=engine But if you want to feel safe, an easy choice is Mobil 1 V Twin 20W50; do you have to crank start your engine below -15 degC at any time? Mobil 1 publishes their level of Zinc and Phosphorus for that oil:

Indeed. What we don't know, what is the minimum ppm we should have. From what I understand, more is not synonym of better. This is the a big dilemma. As I have read, consumers are not really interested in what oil is used in their vehicles. There is some common interest in vintage vehicles owners though. Kudos to RedLine for indicating levels of Zinc and Phosphorus. This is what I am trying to find from those who don't specify whether these are included or not.

The SAE J300 tables help define a motor oil selection according to your own environmental conditions. (refer to the table below) It is not all about ZDDP though. There is another parameter we should not ignore: HTHS which stands for High Temperature High Shear rate viscosity. SAE (Society of Automotive Engineers) classify if four categories the oil viscosity: 1) HTHS that controls oil film thickness in bearings 2) LTHS that relates to engine startability (LT= Low Temperature) 3) LTLS that relates to oil pumpability (LS=Low Shear rate) 4) HS viscometric effect that influence fuel economy Because in Texas we seldom see temperatures below zero degree Celcius, I could use a multigrade oil starting with 25W; I currently use 15W. Of course, if I go to Alaska and leave my bike outside, I would need to do an oil change. The other side of the grade scale is more challenging to comprehend in relation to our "ancient" V11 technology. In the user's manual Moto Guzzi recommended 40, so we could safely assume that it is the lowest grade choice. If you check the manufacturers' websites, some provide a motorcycle oil selector. For those who have Moto Guzzi V11s, 5W40 is often suggested. But it is the easy part in our never ending quest for the best oil in our V11s. Oil manufacturers in their vast majority only publish the SAE results.

One tattle tale, or tell tale, would be blowing that 15 amps fuse if staying with the start button depressed too long.

@docc When I read the OP's narrative, I think of what happened to me last year. It could be a similar issue to mine, which is now just a memory that I tell while sitting around the fireplace.

06-May-2022 refuel at Buc-ee's I-10 Baytown. Unfortunately no Ethanol free gas at this service center; 80 miles mixed of I-10 (West and East) and traffic ridden errands. I have not refueled yet and have gone beyond the 150miles.

7th Stop: 101 Dalmatians giant fire hydrant: #26 193 miles return trip.

I am working on oil at present. This is so unfortunate that excepted for LIQUI MOLLY, none of the oil manufacturers are answering my emails. I found some websites with similar interests and motorbikes than ours. Understand this as: "older motorcycles, 4 strokes, ranging from one to six cylinders, air cooled. So far, I have been able to recouped some information; 1) Multigrade oil is admissible. Fully synthetic oils are best. 2) Grade range should be selected according to the specific temperature conditions your motorcycle is mostly exposed to. The biggest challenge, is to find out about the additives list and amount. The so-called ppm of ZDDP (Zinc) and Phosphorus which our V11 require. My current quest is to clarify which oils if any, still contain those elements. From what I understand the oil components that we had in all oils for older motorcycles may no longer be present in those conceived for modern motorcycles. This is the information I have been looking for.

I think our languages are full of these idioms that we use without second thoughts. "Pulling the trigger" does not exist in my language. Nor does "shoot", you know, "can I ask you something? shoot!"

It is all fine. I think incident happens. I have not yet spoken to the guy who was driving it, but I will. So far, I only spoken to the owner. I want to get a full understanding on how a simple turn at a red light causes someone to lose control. There maybe a perfectly valid explanation, I simply want to hear it from the horse's mouth. They sent me a text the car is ready for pickup. But tomorrow I am planning to go to Beaumont to check out that 101 Dalmatians fire hydrant. On that topic, I never ever drive someone else's car or motorcycle. I am always afraid this kind of incident could happen. Even if you are not responsible, you still feel like you are.

For sure, this guys has many skills... not often housed in the same person.

If only for the unfortunate pronunciation of Guzzi, and Motocyclette Certifiée non conforme, this is trulya work of art and dedication!

The "cross" shape of the dipstick is supposed to help retain the oil using the "liquid surface tension". Although it is not "at a glance" reading, it is possible to get a level from that Guzzi dipstick. I asked my good friend at LIQUI MOLLY, here's the answer: the dipstick is calibrated to be accurate when the oil is hot (my guess). Quote: Technically it is absolutely normal to check the oil level at operating temperature. Oil has a different behavior and a different volume when it is hot, so to make sure the oil level is correct when the engine is running the level should be checked / adjusted when it is hot. We hope we could help you with our information. Should you have further questions regarding our products we would be very pleased to get contacted from you again. Freundliche Grüße / Best regards i.

The latch receptacle of the soft top. This is located above the windshield. When you close the top, there is a claw that comes in and locks the top automatically. The latch receptacle is held by two screws that are held in bushings made of brass. He replaced the screws but split the brass bushings when screwing it on. He said he used a torque wrench and used the required torque. I don't usually drive with the top on, but sometimes I close it to avoid transforming the car into a bath tube when rain is predicted. This is when that latch receptacle fell off. As for the what exactly happened during the incident, I went to Einer's and no incident report was done. I can only give them the benefit of the doubt. They could have said nothing too. I would probably have not noticed since the damage apparently only on a rim.

@docc TCO, is something I keep track of for all my vehicles. I do not have an unlimited budget, and knowing TCO is primordial. Some unforeseen costs may make ownership unsustainable.

Apparently during the test drive the technician was ran off the road by another car.... What was the Murphy law for this? if anything can go wrong, it will?

Catastrophic; Major (order of classification of failures) Total Cost of Ownership

Just for conversation' sake; does anyone know why we need to check the oil level warm? In the old days, the recommendation was to always check when the engine was cold and the oil fully collected in the sump. With a wet sump of course. Dry sump required to have the engine running to check the oil level, as for the Honda CB 750. Why would Guzzi recommend running the engine for a few minutes, stop it, and then check the oil level? I am thinking, and correct me if I am wrong, synthetic oils expend a lot more than mineral oils. My guess is, that dipstick is calibrated to be accurate with synthetic oils, meaning with a cold engine, the oil level would be shown lower than if you followed the recommendation to check with warm oil; making you possibly top off the oil when it is not needed.

Having a black engine does not help the trouble shooting. I did check the tightness of the hoses connections to the oil radiator.

These worm-screw adjustable collars.... Thanks, I have now an idea at what I should be looking for.

I found that hose on MG Cycle, and found another topic in the forum. The oil coat is on the right end side of the engine. Bottom only. I took some pictures let me try to find them.

Anybody has photos of the intake of that hose? my engine gets oil slicked when I ride on long run. Only the right end side. That breather hose was indicated as a possible culprit.

I have a permanent tendinitis in my left wrist. When I spot a slow down or a red light, I slow down hoping to not have to stop and use the clutch. Typically, I would not run that slow.
