Hey Scud, On the top of the master cyl. there should be a seven or eight digit number stamped into the flat boss. The last two numbers will be the diameter ie 16. BSANUT on ebay usually has an assortment of Brembo stuff. Paul B

^^ I spy the V11-Hammer-Badge-of-Honor . . .

Try these guys: Ducati Brembo 12mm Front Brake / Clutch Master Cylinder REM REC Seal Rebuild Kit 110436292 KTM Aprilia Moto Guzzi (gothamcycles.com) Then search in their website for Ducati Brembo Master. You need to know the diameter (eg 14mm). I presume that you are a "certified brake technician"?

Thanks for the offer, @Randown! Just a note that Randown has been a member here since 2009. Nice Ballabio! Rare to see them in grey . . .

Pretty sure that spring is not available by itself, but the rebuild kit is not expensive. I do recall having to Dremel cut the retention ring that holds it all together. You might see if simply bleeding the clutch with fresh fluid restores your lever travel before we condemn the spring . . .

Some previous discussion here: https://www.v11lemans.com/forums/index.php?/topic/22114-front-brake-master-cylinder-rebuild/#comment-254615 You need a 16mm kit, given Phil's comments. And yes, I think a preventative rebuild is a good idea, especially if the fluid has not been changed every 2 years in the past. I found a rusty spring in my clutch MC. I haven't yet rebuild the front brake MC, so should take my own advice.

Here's a favourite of mine Kenny Brack Goodwood 2013 Ford GT40 in the wet. When I was teaching my son to drive I showed this video to him to demonstrate the speed at which a car gets out of shape in the wet if pushed too hard and the reactions and pre-emptive skills you need to keep it on the road. If you think as a amateur road drive you have those type of skills then you're mistaken so don't push the limits on the streets. Ciao

If you're thinking of tackling any job to do with the clutch M/C; imo I'd read up on Scud's ingenious idea to eliminate a nightmare and install a remote bleeder line from a Griso or Stelvio. I still curse when I think of trying to bleed that sucker, rebuilding the m/c would be the nightmare 10 fold for my meager skill set. fwiw

For a Indy winner, I'd bet it's a piece of cake compared to going flat out into Turn 1 qualifying at The Speedway. It was pretty funny watching him pass so many cars in the wet like they were parked. All of them classic '60's sportscar racers.

Tons of detail on changes by year, so it depends on what year you want to compare to. The Ballabio's flyscreen is mounted to the frame, rather than the bars as the earlier sports.

On my 2003 Lemans, riders left, there is an similar looking piece at the bottom of an adjustment contraption that adjusts the aiming? of the headlight bucket. Mine has a slot cut in the bottom for a screw driver, and appears to be threaded and mounted with a slotted boss at the top to locate it on the bracket, then passes up through the middle of a spring with a nut at the top. Just a wag but yours is probably a variation of the same mechanism in that location with a slightly different design.

Sharp machine.

I take it Paul from Florida is in the writing of "advertising copy" line of work. Ciao

Posted here first, low miles, turn key ready to enjoy, pictures here: https://1drv.ms/u/s!ApfE3KXJ6gPfhJxiQTteMLTKjDYJhQ?e=FdvDhg Haven't figured on a price yet, will update soon. UPDATE $6.9k is the initial ask with the intention of adjusting after some while if it's necessary to meet the market. Posted hi res pic copies. Purchased with 263.0 miles on the odo from OC Harley Davidson in Irvine CA Never down or crashed. Inquire here or text V VI II VI I IX IV VIII VII IV.

Headlamp had burned out (connector has power) on the V11 and she needs a new front tire...so on the lift she goes. Fairing removed (for my piece of mind in case getting it up on the OEM stand goes awry) and in the process of removing the headlamp from its bucket this hollow cylindrical thing falls to the floor (headlamp included for scale). Can't make out any internal threads, and the ID is consistent with the OD of that bottom center screw that allows the headlight to be removed from the bucket. Nothing jumped out at me in the PL/exploded view for the headlight. Is it a spacer thru which the aforementioned bottom center screw fits before it engages the clip in the bucket?

r Seat cowl arrived from Germany safe and sound. Rear fender/mudguard all sorted out. Next project is cracked ABS starter cover and left side cover.

No - that one uses the four treaded fittings on the swingarm, same as the stock one - so it has those four long CF "legs". The Ghezzi Brian one comes with a bracket that mounts with the lower shock-mount bolt. After installation, it looks like it's just floating over the tire. Here is a close-up of the bracket and how it mounts to the lower shock-bolt: Here is the fender from the side: And as luck would have it... the Nero came with the other type of fender. It was beat up (deeply gouged and some chunks taken out). Trash hadn't gone out yet, so I was able to lay it over the top of the installed GB fender for this photo. Surprisingly, you could mount that fender without removing the GB one (you can see it peeking out in a few spots). And if you look carefully, you can see the GB bracket too.)

Scud, is this the same rear mudguard you have ?

Goofman's GB has particular provenance and legacy status. They really are delightful little things, both to ride and behold. Twenty-seven years ago, I had to consider selling mine because of an impending relocation. I decided against it, but an inquiry about it brought me another lifelong friend. Motorcycling is awesome. The riding is good, too . . .

Hmmm....point taken. And hopefully, point made. Docc's, and many other's machines, are not bikes, they are legacies.

Thanks guys. I think I'll order the spring and have the clutch fluid changed with a rear tire replacement and driveshaft service? Kill three birds with 30 stones (rather than a single bird with 27 stones). I suppose there is logical reason for burying the bleeder.

Another view of the slave (with no swingarm) showing the location inboard of the (1st Gen Chuck-Made LuckyPhil Extended) shift arm . . .

Here is an image of the Grimeca slave cylinder from a rear view with no swingarm in the way. The bleeder is capped at the top left beside the clutch fluid line. (The red circle indicates the important main ground to the back of the gearbox which is not part of this topic).

Okay, here is a link to a the thread about the broken M/C spring with images of the failure and rebuild kit parts:

When my lever did that I found a broken spring inside the M/C. I recall another report of same. M/C rebuild Guzzi part # 110436292 (12mm) The bleeder is on the slave cylinder on the very back of the gearbox. Fiddly to get to, but possible. Let me scare up some links & pics . . .

Thanks for the lead on the rebuild kits. I got one for the rear master in the mail yesterday (thanks MG Cycle). I have some clutch and brake masters in a box. Maybe I'll break one down and measure the piston. MG Cycle also sells the kits based on diameter, but they couldn't tell me what kits to get. I'll probably learn that when I complete my "brake certification training." It would be good to document the appropriate kits in our Encyclopedia of compatible parts. I already replaced the clutch line and added the new fluid reservoir, and the master still works (as does the slave cylinder). Do you think a preventative rebuild on the brake masters is worth doing - or will these 20year parts still last for a long time with their current seals and such? As for the CF goodies. I got the rear fender and the belly pan from Ghezzi-Brian for EU 490 including shipping and all customs charges. They don't list prices on their site, but they respond quickly via email. Also picked up a new CF front fender from ebay (an Aprilia uses the same mounting pattern as the V11 with Ohlins - see encyclopedia for details). @nobleswood if you buy one, would you ask Bruno to throw in an extra bracket for the rear fender for me? I'd like to lower the one on my Scura. I'll pay you to ship to me.

Nice old airhead Bimmer, too!

Looks pristine! Beautiful bike!

Thanks very much. It's a work in progress.

Got some carbon fiber goodies from Bruno (aka Brian) of Ghezzi Brian. It's always a happy day when packages arrive from Italy. I rather like the small rear fender, which I have on my Scura, although it sits a bit too high above the tire. So I was pleasantly surprised to find that GB have modified the bracket to make the fender sit closer to the tire (you can actually adjust it till it touches the tire, so be careful). Now it nestles between two rails on the swingarm, (it sat above the rails with the prior bracket.) It was also pre-drilled with mounting holes, which almost lined up with the bracket, and the holes were almost big enough for the included mounting hardware. So let's call those pilot holes. Dremel tool with small stone-cone bit required to get good fit and alignment. So, still kind of a weird shape on one side, still not perfect, but definitely improved. See thread re what makes these bikes quirky... Two reasons I like this fender: 1: it does a surprisingly good job of keeping debris off the lower shock mount and transmission. 2: you can see every inch of the beautiful swingarm, wheel, and final drive (unlike the massive stock unit that hides everything and shovels crap onto the aforementioned areas.) And possibly true but almost certainly irrelevant... it reduces unsprung weight on the rear.

What an awesome solution, Marty! Welldone! Let's all be acutely aware how critical it is to keep that area well greased lest the nose of the crown wheel become ruined from moisture infiltration and the drive will so longer seal.

The Jag was posted by @al_roethlisberger in our "Cars" thread in "Banter." I moved @Guzzimax's car post there (nice Bimmers, g'max!)

Guzzis are quite idiosyncratic. It's just that they idioSYNCH perfectly with a select few humanoids.

I always grow attached to stuff, whatever it is, and can never let go of it. Be it a book or a car. The more I have it, the less likely I am going to let go of it. There is only one reason I am going to part way from some of the things I have accumulated along the road; death! I have seen now enough around me, to understand that all those souvenirs that we could not live without are probably not going to matter to those you leave behind. For the most part. I have a large collection of guitars, and I have seen what happens with those lot purchasers. So I am going to set my affairs in order. As long as I can stay topside of my Le Mans, it will stay with me. But if my health decays to the point where I can only look at it from afar, I will find someone to perpetuate its desire of motion.

A "certified brake technician" I've never met one of those. I've met technicians that are certified in breaking things though. Ciao

Re mirrors - I don't know anything about Valentin. But they are genuine Napoleons. And like others have said... you really need to get that bike tuned up. Don't try to cure the symptom at the bars, try to cure the problem in the engine. The Napoleon mirrors look cool and give better visibility than the stockers. Those are the only reasons to buy them. And on the down side, they somewhat limit your lane-splitting ability. Re the BMW cruisers - I rode them at a BMW demo day at my local dealer. I really wanted to like them, but they shook terribly at a reasonable mid-range RPM - and the seat vibrated (which I guess is a "feature" for some people). So you either had to lug it or wind it up. Apparently this was done intentionally so it would feel more like a Harley... so sad... they sure look pretty though. Instead of a new BMW cruiser, you could buy a low mileage Audace and a California Touring and still have money left over.

What confuses me is that I seem to have moved into a parallel universe where the normal laws of physics are reversed. For every 1 KG of food I consume I put on 2 KG of weight, sigh. Seems my body has turned into a perpetual motion device and actually runs on thin air and stores double what I eat. Ciao
