Cheaper and more convenient, I agree. Easier? so far, I only found the one on eBay, which bevelled box looks terrible.

You are correct. The Quota stock ratio is 8/33; Harper has the gear set in stock for 670 USD. https://harpermoto.com/products/gearset-8-33-30354602

I have shimmed electrical submersible pumps before. The principle is the same. My immediate concern is to get that pinion out, so I can assess its status. Once I have some factual parameters, I will be in a better position to decide what to do. The safe way, would be to replace the final drive. I found new ones in Europe, for 1500 EUR, plus shipping and whatever US import tax of the day. Harper has new 8/33 pinion and ring gear in stock; I want to retain the 7/33 ratio. eBay has one final drive on sale, for 200 USD. No history available.

@audiomick I found a tutorial of what you need to do to adjust the flange and the pinion. The Guzzi manual shows what you should achieve, and what to do in case the wear is not as in example #1. He explains that the one he is showing has done 200,000 km. And the pinion ate the spline.

@pete roper I see what you mean. No access from the oil level port.

I want to have a look to see what 220 miles of riding without oil did. I have the oil fill port to check what is in the way. If I can't get it out this way, I will go back to finding a vise.

Something came to mind last night, while we were under heavy thunderstorms in Houston.... Why don't I use the oil level port, to chase the pinion out, using a bronze rod.... this would work better, since I would act directly on the pinion head... Now I need to find a bronze rod that can go through the oil lever port. Also, once I get the pinion carrier out, what can I use to clean the inside of the box from any burrs, without damaging the o'ring and seal?

Somewhat, the Aprilia was known to be performing well at Silverstone; so does the M1. JM's spoiled his relationship with Aprilia. It reminds me of Zarco and KTM. Different circumstances, since Zarco established he could not race properly with the KTM.

Fabio Quartararo losing on winning the race because his ride height device locked up, was unlucky.

I found a dolly with adjustable width and height. https://www.redlinestands.com/catalog/lifts-c-290/parts-accessories-c-290_304/motorcycle-dollies-c-290_304_115/kl-supply-mc460-motorcycle-engine-cradle-dolly-p-493 This one too: https://www.redlinestands.com/catalog/index.php?main_page=product_info&products_id=2860

My Quota experience is documented in this forum. I bought mine in February 2024, from a lot seller in Peoria Arizona. I went there, purchased and brought the bike to Houston riding. I completely agree with you about the Quota. It is my GOTO vehicle, the V11 Le Mans being now the exception. In 2024, I unwillingly got dragged into riding in terrain while participating in a drive to raise funds. All the other bikes were proper Dualsports. We did not do anything that would have impressed Travis Pastrana, but the Quota (and me) surprisingly held their own! during that ride, we hit all kind of terrain, including sand and loose gravel. I was more the limit than the bike itself. Equipped with Trail Mission tires. My Quota was tuned by MPH in Houston. When I brought it back from Peoria, the bike had no idle, but otherwise did the 1200 miles without a flinch. I am on a Quota group on Facebook. I have had a rear end issue, when I lost the final transmission oil drain plug. Some Quota owners have replaced the 8/33 by a 7/33 ratio, including an 18" rear wheel. I have done some far and away travel with the Quota, still do, and I am fine with the current gearbox stepping. That 5th overdrive comes in handy when I have to be on highways. Not in theory! this bike is a camel...

That's what I need. A way to move my bike around in the garage. But I need something that fits the Guzzi. I was trolling around to see if anybody else used one already, rather than starting a search for one that fits the V11 and the Quota.

@audiomick, @docc The floor of my garage has been surfaced and painted; it is as smooth as it could be. A dolly would work wonders for me. For example, if I had had one today, I would not have needed to reinstall the final transmission, put the wheel back to garage the bike behind my car. Docc, the ceiling of my garage is made of sheet rock! There is nothing that will hold a bike. Those houses are cardboard built, with wood. Haussman built apartment buildings in Paris in the 1800. They are still standing and lived in. The housing quality where I live is below everything I came across before... and I have been in many places, including some that do not have indoor plumbing...

I know the feeling.... This is what happens in Monaco on F1 GP.... I have been there once... my dream? driving my Le Mans to l'hôtel de Paris, and handing the key to the jockey to park it....

I took the final transmission off my Quota this afternoon, and reinstalled it to enable moving the bike. Anyone using a dolly? such as this https://letsroll.store/product/lets-roll-low-profile-motorcycle-lift/ https://letsroll.store/wp-content/uploads/2022/03/Lift-Demo-v04.mp4

I realized it immediately after I found each screw had some sealant or Loctite on them. It was fastidious to remove them, and once they were all out, the flange did not move at all. It was worth trying. I am afraid to break the casing or damage the flange. If I could hold the pinion carrier spline in a vice, with protection to not damage it, I would probably be able to do a better job. Tuesday, I will go to one of the motorcycle dealers I know, and I will ask them if they let me use one of their vice.

No luck removing that pinion assembly from the carter. The drain plug is again full of burrs, which makes me think there is much more than what the magnet can capture. I have reinstalled the bevelled box on the bike, the rear wheel, so I can move the bike out of the way. My next move will be to bring that bevelled box to a workshop so they can remove the pinion assy. I removed all the screws of the flange, all were stopped with loctite, it was fun. I don't have a power driver, I only use hand tools... The flange did not budge either.

I have removed the bevelled box from the shaft. The pinion carrier does not come out. I don't have a bench. I hold the box by the spine, and with a soft hammer I have tried giving a few knocks on the carter to get it moving; so far, without luck. It is not the best set up, since I am holding it by hand. I think I am going to remove the flange. It may help to look at it from the inside.

Another atypical race today, atypical being an understatement. Luck always play a part in everything we do. Some people get lucky, others, not so much.

That rattling noise we hear when you attempt to restart indicates a current intensity drop, which confirms an electrical issue. On a different note, I had some electrical issues with my V11, including the starter shorting internally (documented with photos), but once you have sorted them for good, then the Guzzi is a rock.

It's the plan!

Point taken.

It's the carter of the ring gear and pinion.

The seller is taking wrecked or disabled motorcycles, break them down to eBay the parts. That is his occupation, and he was honest in telling me he had no idea. This is not an MG specialist. He just makes a living out of selling parts. It is cheap enough that I could purchase it anyhow. I have been waiting for more oil. Reason tells that I should change everything, as a matter of precaution. I do not think the rear wheel would lock up because of a drive pinion worn down prematurely. Since I had my 996 IMS changed, I had the opportunity to discuss the reason why those bearings failed. A lock-up would most likely be caused by the bearings. I am going to get to the bottom of it.
