Good evening everybody, last year I build my personal Guzzi café racer . Unfortunatly I didn´t get younger in the past 63 years, so I prefer riding on my V 85 TT, the best Moto Guzzi ever left the factory in Mandello del Lario !!! Best regards ! Jürgen

Low idling Cheers Tom.

Yeah, it is not normally a high pressure situation, so the intake pipe does not need much to stay on. It is actually normally a low pressure / vacuum situation between the head and the throttle bodies. It should not take much to keep it on. But you can see one of the slots in the metal intake spigot that the rubber boot grabs in your picture. Something went wrong to pop that off.

I believe their only purpose is to keep the spacer more or less lined up with the hole in the bearing so you can get the axle in.

We know that it's important to have the rear wheel spacer stack-up right, or bearing life will be short. It's difficult visualize the parts that make up the stack-up, so I marked up manual pages in the attachment to show the parts involved in clamping the inner races of each bearing. Sizes are included. The sizes are my measurements, so if you have any comments, then I can edit the pages. V11 Rear Wheel Spacers v1.pdf

MPH is one of the too few places where you can get your vintage motorcycle looked after; At one time they were a Moto Guzzi dealership, but have parted ways with Piaggio's take over. I visited with them today, August 7th 2023, and was informed Mike, the owner has sold the car part of the business Mike Haven Automotive, and they are going to move the Motorcycle repairs to where Mike lives in Hempstead Texas, Waller county. The move should take place before the end of 2023. Mike says this will save them the commute, and will improve the turn around time for the bikes, which is currently around six weeks.

I missed this thread last month. Sorry. We fly this pair flags twice every year: 6 June and 14 July. We also fly the flag of France on 5 May ... That pairing on Cinco de Mayo no doubt puzzles many, but think how wonderful Mexican cuisine -- already fine, IMO -- would be had the French won! Bill

Mike, Todd, Davey, and others there over the years made MPH unforgettable and part of Moto Guzzi lore.

The metal "intake pipe" is not totally smooth, there are some ridges. And the Rubber boot has matching features inside, so it does seat. In addition to what Docc said about tuning, it's worth inspecting the system for other air leaks - both the boots and the vacuum hoses that attach to the intake port. And since one boot is already off, why not do a quick clean on the throttle bodies?

Those are nice cars. Especially the styling. But they perform well also.

I've likely got a spare (I had several made years ago) for the cost of shipping. Can check if you like.

Incidentally, I didn't put in three links to be a smart-arse, but rather to give an idea where one can go to check on part numbers. PS: docc beat me to it, but I worked so hard on this I'm posting it anyway... PPS: I read somewhere about spacers to fill out the missing length on the spacer. Don't know if it was here or somewhere else. That might be an option, if you can figure out how much too short yours is. Apparently a bit too long is not as bad as a bit too short. Having said that, I can imagine that an additional short spacer in there would be an absolute pain to install.

If classic Tonti’s are the big blocks Lino’s must be the ‘lil small blocks

Yeah, me too. Back in the day I crashed countless times running enduros. Most of the time I could throw the bike away. I have visions of a top box hitting me in the ass and taking me to the scene of the crash.

This morning, my Le Mans started to run on one cylinder. In the 87 Octanes topic, I reported that my V11 had a lot of misfiring. Fortunately, I was less from a mile from my house, on my way back from a run, so I limped back and a quick look at my left intake identified the root cause. The rubber boot had slipped from the intake pipe, and was no longer sealing around it. I was intrigued to find out there seem to be no lip on the pipe to prevent that kind of mishap. I have seen similar assembly with the pipe having a lip and the rubber boot a groove underneath the collar recess. Tightening the collar would lock the boot onto the pipe. But here, it looks the pipe is smooth, so the rubber boot is only held by friction. If you have not, worth checking on your bike.

I am lucky, I get to celebrate both now.... The difference is that in 1976 (just a "few" years ago then....) I was in the military and participated to the parade. This year, the Indian PM is the guest of honor. My next objective will be to descend the Champs-Elysées on my V11 Le Mans, for the posterity!

That is correct Mick Phil

That occurring can be a sign of throttle body imbalance (or imperfections in the tuning parameters, i.e. TPS and valve adjustment variances).

I found the instructions in the FAQ section of their website. From what I read, the GPS odometers can be programmed by the user. The mechanically driven ones need Speedhut to do it.

Here ya go @docc Sorry for the dupe posts. Getting used to how this site works: I did email Harpermoto. I tried calling yesterday but no answer. I'll try again tomorrow. I didn't figure they'd be open today. the length of my current spacer is 112.7mm as accurately as I could measure. Also, i did a web search using just the numbers as you stated above an dI was able to find a couple of places that show the part, but do not confirm it's available. All the research I've found has show the spacer needs to be 113.2 (+/- .1 mm). My numbers are an average of the different info I'v found. Additionally I'm happy to shim the existing spacer if I can find the shims. I have no idea were to look for those. Thanks all for the replies!

Yea docc thats why I always actually use "Guzzi part" not just Guzzi before the numbers in fact. Forgot the "part" bit. I must say parts are getting harder and harder to come by these days. New parts are thin on the ground and used parts are more affordable but there's a lot of "suspect" parts and sellers out there and shipping is making the costs exorbitant. You should see the cost and speed of availability of RE parts direct from India. The parts are dirt cheap and the service is the best I've ever experienced. Hows $300US for a brand new painted fuel tank shipped to your door in under 10 days sound. Phil Phil

There is only one way to know the required bearing spacer length. Measure it. As already pointed out the factory has supplied 3 different lengths at different times so how do you know 113 is the right answer for your wheel. When you remove the first wheel bearing use a 6"vernia to depth measure between the old bearing race ( provided it isn't totally shagged) and the wheel bearing recess shoulder and thats the spacer length you need plus, .1 to .2mm exactly. Any less than the base measurement and you'll have bearing issues any more than the baseline plus .2mm and you should be fine. A little longer is fine a little shorter is not. Years ago I used some glued on shims to adjust the length of mine as it was only .5 or so short and I couldn't machine up a new spacer at that time. Phil

113mm is correct. IIRC, there were some very early spacers 110mm. So, all along, I thought my 112mm spacer was "fine." Not so! Take it from a guy that learned this the hard way! [edit: Plus: those SKF totally put me on that rollback 310 miles from home. I'll never run anything but: KOYO 6304 2RS C3 Deep Groove Ball Bearings 20x52x 5mm for that application . . .

I believe I have read here that it is supposed to be 113 mm. . Is that correct? Relevant to me because I expect to be changing the wheel bearings in the rear wheel of my 2002 Le Mans in the very near future. I'd like to be able to check the length of the spacer while I'm at it.

That is good advice! I find that some websites use the GU and others do not. I always search a particular source both ways.

You leave off the GU when searching for or ordering Guzzi parts. Just use the numerics. Phil

Welldone, @audiomick! Here it is at Harper (Missouri, USA), but seriously, call Curtis to verify availability: https://harpermoto.com/products/spacer-inner-a-01634000?_pos=1&_psq=01634000&_ss=e&_v=1.0

Verified Inner Spacer part number: GU 01634000 Mine came from Harpermoto in 2019, $30.70US. For best results "call" Curtis. "On the phone." Once in hand, verify the replacement spacer is the correct 113mm. I have also had the very best results with the KOYO bearings in C3 specification.

What does your existing spacer length measure, @BlackEmperor_Moto ? The upper, 112mm, spacer ate my wheel bearings forever. The lower, 113mm, spacer was the solution.

I don't recognize that connector as original to the V11 stator (?) An electrical failure like that can be hell on downstream components (regulator and relays). Be aware of/ monitor for sequelae . . . [edit: it also occurs to me to check the attachment of the two yellow wires to the stator under the alternator cover for breakage. Probably not "on the road", but when home.]

Yeh, sorry Docc. I meant isopropyl alcohol, or any mild solvent. Using your IPA would be wasted.

Focused on the front collar I was so excited about the possibility of finally finding the elusive reason why the Short Frame front U-joint is SO IMPOSSIBLE to approach. It occurred to me that, if the later front collars are a larger ID, that would be the difference. If not, The enigma remains . . .

So because of a huge house renovation, I have not had a lot of time to ride my Italian bikes However, the previous car was increasing in maintenance (and a diesel, which was not the right choice anymore), so I wanted something else. And well, the Italian blood was already there, so I bought my 4th Italian vehicle, this time with 4 wheels.
