80CX100

I'm not sure when the American V8 started their basic design, but I just watched this video that had been posted over on WG. The basic guzzi engine, drive shaft design has been around a lot longer than I thought. fwiw

From the Google, German to English translation in the a/m link that LP posted above; Wth is this in laymen's terms "It is also the first Moto Guzzi to be equipped with a six-axle inertia platform (IMU)" I take it that it would be something instead of the CARC system, but 6 axles?

If you were interested in it, but didn't get out to one of the screenings, they've just released the Motorcycle Man DVDs about Dave Roper for sale, Santa's bringing mine https://www.motorcyclemanfilm.com/store/motorcycle-man-dvd MOTORCYCLE MAN DVD 20.00 Own a copy of Motorcycle Man on DVD and enjoy the film along with special features such as deleted scenes and extended interview outtakes. More than 80 minutes combined! Dave Roper is a legend, but he carries himself with such humility, I don't think there's a finer gentleman worthy of supporting. A Class Act

I don't know if quirky is appropriate, I would reserve that to describe the traits on some of the UJM's I've had, my Suzuki DL1000 VStrom had hours worth of tupperware to remove just to see what had to be removed to do a valve adjustment; all held together with magical rubiks cube plastic fasteners that only divulged the magic password after you broke a few. The top notch engineers at Suzuki after much design work and testing, determined that Oxygen was the best material for the seat for the hydraulic clutch seal, now that's Quirky, but I digress Guzzis at the core, are pretty straight forward, simple engineering, that reward hands on involved ownership. If every time a valve cover leaks, the sump drips a bit of oil, the side stand bolt loosens, the grounds get corroded, you want to make a run ro a dealer to fix the peripheral nigglies, I think you're setting yourself up for a world of heartache. For that matter, just trying to find a dealer can be an exercise in frustration , let alone find one that can do quality work. Guzzis reward what you put into them imo, I've never felt that planted on pavement on any other brand, the engine powerband has a character that works well in the real world. I will admit to having more of a fondness for the flowing gracefulness of the Tonti framed bikes, you can tell when you work on a Spine frame that they evolved on a race track, added brace, changed this or that, bolted together here there and everywhere, it's quite the collection of fastenings, brackets and bits. fwiw ymmv

Absolutely. Not being naturally mechanically inclined, I research every job I do, ad nauseum. I had read many times on the difficulty of getting the new Valtec tensioner into proper position and that it was tough, it wouldn't break, just force it into place. I proved that theory wrong and the brittle plastic broke right at the metal support/pivot post, and I had to order a replacement. I think I was lucky that it broke right before my eyes and I had a chance to correct the problem with a new one. More gently installed the 2nd time, by disassembling it, and reassembling it in proper position. I've subsequently read of a catastrophic engine failure due to the Valtec breaking apart, hidden out of view; I'm sure that the point of failure was at the same stress point, but if it cracks during installation and you don't realize it, you can pay a high price later on for an obvious weak spot in the design. fwiw ymmv

When I did the timing chain and installed the Valtec tensioner on my CX100 it only had 24k miles on it, but it was loose and sloppy enough to have started to wear inside the case. You could really feel a difference in how much tighter and uniform the whole ignition timing/firing system was. fwiw

Yup, I thought the same thing when I saw that bike for sale; if it's legit, in decent shape, good bargain. The prices are rising on those in Canada, I'm guesstimating, with that mileage, it would list for at least 6-7+ up here. fwiw

If that is a Givi 755 (looks like it with similar hardware). I picked up an old one on kijiji cheap, intending to use it on my G5, so I'll be following this thread closely. Hopefully someone with knowledge or experience chimes in. Good luck and tks for the post

Thank you. With the challenges I had on a variety of tight clearance issues working on the V11, I tried to do this relocation of the battery tray twice, it sounded easy and simple enough; I gave up in frustration on both unsuccessful attempts. Iirc the main challenge on my bike, was one of the threaded nut tabs was off kilter and welded too close to the frame rail. The 3rd successful attempt, involved bucket loads of patience, a variety of new longer bolts, and I may have had to resort to the use of a file, but I was very glad to finally relocate the tray mounted underneath the tabs; As you're learning, it's a tight fit in there and every mm of extra clearance is a good thing. fwiw

I agree, I've been stung in the past ordering a big bulky "in stock" item and filling the box up with little items I didn't need to help with the high International shipping costs, and ended up without the item I really wanted. When Curtis recently canvassed for information to improve their site & business, I mentioned that carrying the good black wire reinforced valve cover gaskets (Valopini sp?) would be nice. fwiw

Hey FG, tks for posting that. Are you going to do likewise on WG? I'm glad to see Harpers taking the right steps to move their business forward. When I was completely clueless, and a newbie guzzi owner, I luckily placed my first phone call to Harpers. Curtis patiently and kindly took the time to walk me through the basic essentials of what I should be doing, to take the best care of my 30 yr old, new to me guzzi. I'll be forever in Curis's debt. I'll have to search out and get on that email list, I've seen some of the special parts and deals he's come across in the past. tks very much.

Tks very much for posting info and photos on the different designs available, some very nice looking pieces of kit. I went through the HMB information, it appears their sump extensions are available with the filter on the front or rear; they caution that the rear filter style will interfere with most crossovers, I can see that issue being a pain with most exhausts, they also mention requiring a new dipstick, possibly new markings on the oem dipstick would suffice, idk. The long term wear and tear from most small road debris on a front mounted filter wouldn't really concern me. It would be extremely unlikely, but an undetected failure of the ft filter on the road wouldn't be nice; but I think if the event was violent enough to poke a hole into the filter, you'd hopefully know about it.

Hey Weegie, I'm in agreement, my head is still spinning trying figure out the logic in the design. The OP's KS forks, as described in the info provided by Lucky Phil, match what you've just described above. A nice balanced design, imho would be with both bearings located and loaded by the edges or interiors, a combination of those forces from the get go on the drawing board, seems unusual. You have to wonder if at the time, they would alter design to match whatever parts they had on hand in the warehouse or were surplus from suppliers and available cheaply. fwiw idk

I'm not familiar with the Euro versions, curious how they compare pros/cons with the Harpers Outsider style. https://www.harpermoto.com/harpers-outsider-pre-1998-models.html

My head hurts when I start thinking about the axles,spacers,bearing races and all the forces involved, quite the Rubicks cube, the ft is child's play compared to the back It sounds like your new bearing inner races have different ID's, if they do, just for shits and giggles, try reversing the wheel and install it backwards, maybe you've got the right bearings but installed on the wrong sides. fwiw idk Before you start ripping and ordering, it would be nice the hear from someone with a bike that matches your design exactly, or have the bearings specs confirmed by a trusted source ie Harpers, MG Cycle, MPH, or maybe Pete will happen to see this; the info on the bearing specs for your design is probably already here on this site. good luck

I've got a 2003 Lemans, my axle and spacers appear identical to yours, but my LH fork isn't threaded, there's a large nut on the LH side. On my ft wheel assembly, the locating forces and spacers are as described by guzzimoto and weegie, the inner bearing races are an integral part of the whole locating assembly, located by the RH 25 mm wider shoulder of the axle, RH bearing, inner spacer, LH bearing, and the LH 15 mm spacer; but I note in your description, you describe the inner spacer as passing THROUGH the LH bearing not up against the inner races like mine is. I'm just thinking out loud, but is it possible that in the confusing transition of fork/axle designs/wheel assemblies mid year 2003, you may have ended up with the incorrect bearing inner race design/spec? Do you still have the old bearings to compare if they're an exact match to the new ones? I'm sure it's a simple problem once you figure out what it is. good luck

As mentioned already, it's funny the strange places they turn up. Although I was a bike fanatic when I was younger, haunted all the bike shops and lusted after the CX100 in the magazines back in the day, I had never actually seen a Moto Guzzi in person through my lifetime. About 12 years ago at work, I'm in the back parking lot on a smoke break, and one of the guys that worked in the traffic office, rides in on a Rosso Mandello; he'd apparently just picked it up from the Chicago ? area in the US on a bus? and ride deal. I was awestruck, be still my beating heart. When the first guzzi you see and touch is a RM, that sets the stage, and is the fodder for a serious addiction, lol

Yup! There's been a low mileage, "minty" one for sale locally all summer, I keep praying that someone will buy it before I do something stupid, lol.

You mentioned installing a Beetle map, iirc all of his maps have the lambda turned off, so I don't think that should be an issue. Have you done a basic tuneup ie, valves, tps, balance and trim? I know some of the CARC bikes were known to have problematic oem plug wires/caps, mainly from owners pulling on the caps rather than prying them up gently, you may want to verify if that's a known issue with your Stelvio. That's all I've got, fwiw good luck

Most of the major Trials Bike manufacturers are now putting out a few electric models. I can see the benefits on many fronts for that style bike and other types of short distance or circuit style dirt bikes, gobs of instant torque, no more finicky highly tuned ICE engines that need frequent maintenance, and one of the main benefits, the lack of loud exhaust noise. The tech is still evolving, a lot of the older used electric dirt bikes (couple of years old) I've seen for sale have had their batterie$ replaced, once that weak link is perfected, I think they'll sell a ton of them.

For years I was one of those guys that rarely(aka never, lol) used eye, hand or ear protection, but over 20 yrs ago when I got serious about my music,which includes my guitar, that changed for me. I'm doing what I can to protect and preserve what I've got. For my ears depending on the machinery I'm using, I've got a variety of muffs and on my bikes I always use some type of little silicon ? ear plugs I picked up at a safety supply store, iirc "ear softs" ?

I'm sure that upon close examination there would be many differences including the fine details of cooling, combustion chamber design etc, but the op's topic was about guzzi's design being inspired by automotive practices. It definitely appears that at some point, someone in Italy looked at the American V8 and recognized that copying the basic design from the back 2 cylinders to the rear end made a lot of sense in a motorcycle, and it does. fwiw

It's been discussed many times in the past, so I'm surprised no one has mentioned it here. The guzzi engine is basically the last 2 cylinders of the old Chevy 350 V8, ie. 90 degrees, low compression, 2 small valves, pushrods, rocker arms, going back to a dry clutch, tranny and drive shaft. fwiw

I may have ridden on Avons once 40+ yrs ago, but since starting to ride again after a 30 yr hiatus, I haven't had them. I know the racing guys in VRRA, especially those riding old smaller bikes with taller, narrower tires, are fanatical about their Avons. Apparently some of the higher end racing styles, aren't regularly imported into Canada and the riders have to jump through all sorts of hoops and spend big coin to get them; and they're glad when they can score a set and get the Avons they want on their bikes. fwiw

It's way above my pay grade and I don't know how they do it, but I have read discussions on WG, that some guys have been able to run guzzidiag on tablets. fwiw idk?
