We should try to find a graph illustrating the principle on a motorcycle. I am sure someone has done it. I am not convinced the pilots doing it understand the math behind the principle, but they can feel the difference. If you think of someone walking on a rope, using one leg to correct the moment of inertia.

I know. At the top of the rivalry between MB and VR, Max always got the short end of the stick. Like other duels, those two guys were a motivation to come back for more.... On the day MotoGP retired number 46, they also inducted Max Biaggi as one of the "legends". I will always remember him from the most extreme wheelie on a race track, almost backwards....

You are correct in stating that Rossi started it. It has to do with moving the barycenter, something well defined in Astronomy. Nasa explains it better here: https://spaceplace.nasa.gov/barycenter/en/ Remember back in the 70's, riders did not really lean out of their bikes. At most, they would extend their knee. The principle remains the same. The world Superbike' pilots don't do it either.

Well, Marquez is getting a fourth surgery on his right arm, so 2022 is done and over for him. Everyone is wondering if he is ever going to be able to come back to the front, where he aims to be. As for the lack of spectators at the Mugello, the costs have also gone up unreasonably, when you compare to the Le Mans GP, which was considerably less, on top of offering two concerts and a show for the price. I stayed in Austin on Saturday night, and for the first time, I got charged the infamous "resort fee" that originated in La Vegas. It seems like every business is using the Airlines technique to hide the fees. No more free parking either, it is Valet only. I was on four wheels this time, but I am planning to return with my Le Mans, and see how the Valet manages....

Those 22 hundreds would have been nice to have to replace a few of the missing features though... but its a Guzzi, so it got good bones, all the rest seems to be cosmetics.

It does not make sense to charge that much. It feels like this dealership in Florida that charges $600 for... documentation....

Today was the day of the rookies.... Marc Marquez will abort his season to get yet a fourth operation as he is now convinced he cannot perform in his current physical condition. I am wondering if he will be able to ever come back to his former self. However what really surprised me, is the lack of spectators at the Grand-Prix. Usually, the Mugello is always full, but this year, it seems to be deserted. Many attributes the lack of interest with the departure of Valentino Rossi.

The reason why the screw broke is because this is the side where I dropped the bike. To be able to put everything back together, I had to loosen the two screws of the foot peg bracket, and pull on the exhaust and the foot beg to align the holes to slide the screw. For the other side, no issue at all. The screws go in and out without any force. I found the relay shown on the left hand side pic suspended by a broken zip tie. What is that relay for? The screws are M8 x 40mm long. I used anti-seize anti-ruts compound.

I noticed that Petrucci hangs the leg out more often than any of the other riders do. I don't see Gagné doing it much. He rides pretty much "old style". Is this because of the bikes?

You don't know how good (or bad) you have it. Insuring a motorbike in Europe is so costly, even a challenge for young drivers. Some insurance companies do not even offer insurance for young drivers. You need to jump through hoops. But driving in Europe is very different. I think it is safer overall there. Mainly because there is a really strict prohibition on driving and cell phone use. Its fine. We just have to adapt and take it into account. Since I have been riding (last year), I have not had a real scare just yet. That does not mean I have not been involved in potential situations, but so far, I anticipated everything. I hope that it continues this way. This is why I am going to take, and continue taking these safety courses. No ABS is also an aggravating factor to my insurer.

More gossip about MotoGP. By the way, tomorrow we have the Italian MotoGP. Aprilia has signed Aleix and Maverick for two more years. Seems that Mir is slated to replace Pol at Honda. Jack Miller may go to KTM to replace Oliveira, or Pramac, or remain in Ducati factory. It seems that the current RNF team will swap bikes with Aprilia. We may have four Aprilia next year. Dorna said that another/only a factory team will replace Suzuki. This remains a mystery. Maybe the Chinese? they would need to poach a lot of talent to make it viable though. Some think maybe Yamaha will have another team to compensate losing RNF.

My company submitted us to a driving test every six months. Testing your handling skills every few years may help you to increase safety and awareness. I took the Motorcycle Safety Course here, even if I already had my driver's license. Mainly because it lowers my insurance rate, but also to verify my level. I am planning to do it again, after the Texas Tour, this time, with the Guzzi, and not with one of these 125cc motorcycle which feel like bicycles.

One of the big defect of the stainless steel is galling..... I mean stainless steel in stainless steel. In my battle tank days, we used molysllip, molykote, and coprikote. A quick web search got me to UK https://www.molyslip.co.uk/copaslip/ But I am certain you can get these compounds here in the United States. It worked on battle tanks taken through terrain, mud, salt water, sand what not.... Tomorrow, I shall install four stainless steel M8 x 30mm CHC. Just to meet the minimum purchase, I now own 50 M8 nuts, 50 M8 washers.... I regret the days when you could simply purchase the exact quantity you needed...

She asked me (Stefanie) how I came to know about their Museum. I said the Motorcycle Tour of Texas... her face lit up, and she said she knew all about it. I liked they kept that roll of paper which was anonymously annotated to be the last one produced from the mill before it shut down.

I did all the purchases from "The nut place" 6605 Gessner Road, Houston, TX 77040-4015; They have all metric fasteners in stock, stainless too, they also have a machine shop, they can do fabrication. Nice and friendly people. I recommend.

I got it out using the "jam nut" technique. I also understood why the head broke. I purchased stainless replacement M8 x 40 mm long CHC screws, but the passenger foot peg holding bracket is not in line with the threaded hole. I need to untighten the other screw to align the hole with the thread. I need to remove the seat skirt to access the other screw though.

I found a spare parts catalog titled V11 Cat. 2003-2004. I downloaded it and shared it on Google drive. Anybody clicking this link should be able to access it and download it. https://drive.google.com/file/d/1gKVAaksRzY3CGASXp0ubwHprffQxac6r/view?usp=sharing

As anybody ever replaced the Guzzi parts with the appropriate specification for the fasteners? Like in my original post, the 12/02 spare parts list from Guzzi does not divulge the specification of Item 42. It would be interesting to have all these Guzzi parts replace by the corresponding specification. Nobody ever did that? On the drawing above, the nut is not shown. Does anyone know what is the latest update Guzzi did of the spare parts catalog? 12/02 is December 2002. Are there any later editions? I found this on the web; but you can only consult. You cannot download the catalog. https://www.parts-motoguzzi.com/moto-guzzi-motorcycles/1100-MOTO-GUZZI-MOTORCYCLES/V11/2004/V-11-Le-Mans/FRAME/Lateral-stand--Foot-rests/422/27/332000152/999

Treatments never work as well as proper metallurgy. Black Phosphate or other surface treatments don't work as well as stainless steel.

When I purchased my first Japanese motorcycle in the early 70's, they all came with cross head screws. I did not know at that time that Japanese cross heads were different than European ones. We ended up destroying the heads rendering the screws useless. But dealerships sold socket heads replacement kits for all your motorcycle cross headed screws. The V11 is equipped with socket head fasteners, but not stainless for the most part. I wish there were stores like before, where you could go and purchase the exact amount you needed, rather than packs of several.

A lot of the fasteners on my bike need treatment. I was hoping it was only cosmetic that I could address after completing the Tour of Texas. It seems that I am going to have to remedy that situation sooner than later. The head snapping off clean on that screw is a wake up call.

My tool box is pathetic Docc.... I have nothing but odds and ends. The proper extraction tool from Facom is expensive. But this is something a guy with a workshop and continuously working on bikes would have. Already finding Metric size fasteners or anything metric is challenging here. So far, I have purchased all the metric tools and fasteners from McMaster.

@docc I can confirm the screws are M8, length 25mm. I removed the elastic stop nut from behind with a 13mm flat wrench. Rather than using a vice grip, I am going to try the old trick of using two nuts one against the other. There is also a tool that grips the threads, I forgot the name. Here's the tool that I would need to use: https://www.grainger.com/category/machining/machine-tool-maintenance/bolt-screw-extractor-tools/bolt-screw-extractors?attrs=For+Bolt+Size|6.00mm&brandName=FACOM&filters=attrs%2CbrandName

I was going to take a picture of my tail bag and luggage rack and I noticed the missing CHC screw on the exhaust support. (click the link for technical description) The head just broke. The threaded part of the screw is still in. To remove what's left of the screw, you drill a hole for an extractor, and hope you are able to get it out. If not, you need to drill the screw out completely, and use an helicoil for the repair. This is item 42 on the Guzzi spare parts catalog. No specification. Is it M8x125, or M10x150?

I still need to send you pics of my setup. I am thinking to use one of the Ventura tail bags to replace the Nelson Rigg I have bought $20 from the account manager where I purchased the bike. It works fine, but the slings keep coming undone.
