One for Mathieu: And one for Carl: Hubert

Engine has arrived. Hubert

Several sources say no. There's a thread already, very well disguised, though Hubert

The seats usually show widely spread diameter tolerances. If the old bearing goes out easily, a normal bearing is good on this side. Does it sit very tight, then a -C3 was probably the better choice. Hubert

Language, words, ain't your favorite tools, are they?

Because others had this perfomance already in the late 30ies, last century. That's all. Just a rhetoric question. Nevertheless it's still a good job to bring a 500cc SR/XT to this level. Hubert

Don't use silicone, it contains acid. I'd use one of those water and acrylic based products, similar to silicone, also available at any DIY store. You have the microswitch outside of the ECU? I have mine open and the pcb laquer sealed. Water may get in, but so it can get out also. If you seal it, water will get in as well - and stay there Hubert

Christian, I do appreciate your hobbies and interests , believe me. Then maybe my first answer was written in a somewhat misleading tone, yes, maybe. But, compared to how much effort and time you have to spend to get any measurable and worth telling results on a flow bench (not to talk of the material/heads you need) I still do believe that this somewhat anachronistic Guzzi 2 valve concept is not the ideal basis for it. And I think you don't work on Guzzi 2-V heads anyway. I was not really asking how many horsepowers these Manx or Guzzis had, I knew that they also were somewhere above 50 HP. RL - that's Real Life Hubert

Maybe. Anyway, RL happens somewhere else. BTW, what figures had the Manx or those old GP Guzzis? Hubert

This flowbench stuff reminds me quite fataly to those great oil temp sensor threads: First class, high speed wanking, nothing else. Get rid of these 120° bends in the inlet ducts, put in 2 extra valves and you have a basis for such semi scientific procedures. Or, as one once had said: real life sex will never hold what masturbation did promisse you! Hubert

Switzerland? Great! How about St.Moritz (good base for 1 day trips, e.g. Mandello). http://www.stmoritz.ch/car-motorcycle-002-010218-en.htm Hubert

I guess it has to do with your dealer. The guy above made similar experiencies with his dealer. So far more or less all solutions for the problems he'd experienced with his Stelvio were solved by a Guzzi technician, not by his dealer. The german importer seems to be very agile in such things. BTW, the Mana that he's actually got came without any restrictions concerning useage or mileage or other things. Hubert

Loc-Tite sounds like a lot of fun - next time you want to remove the instrument housings (bulb change or so). I'd suggest something less secure. Hubert

Paul, do you know what happened to this guy? http://www.v11lemans.com/forums/index.php?...14516&st=75 Where can I find more info about this german fellow's story? Treffpunkt_1100Sport? Hubert

LOL, when did I say this? I'm really curious where this idea comes from. Is it my bad english or is it something on your side? I told BFG not to fight the Guzzi/Piaggio windmills, instead he should better fetch and run the bike as long as it is still under warranty. That's what this German guy obviously did and, according to Paul, he now has a new engine. (I deliberately underlined the keywords this time. Maybe a more visual aproach makes the content of the text better understandable.) Hubert

Theoretically this should work (having TDC set to 1), practically I found it was more important to have valves and synchronisation set correctly for achieving a reliable idle. Hubert

... but with stunning front brakes! Hubert

......That's friggin brilliant! .... Have you considered to just turn around the ecu, so that the connector points downwards? Hubert edit: seems as if I came a bit slow with this idea

The right side's the right sight, but the left one's been designed by a different guy I'd say. Hubert

Tom, what is this red and silicone secured thingy? Haven't seen it before. Hubert

Anyone keen on my fist thoughts about that? Hubert

I wish he would. I tried to make clear that he hasn't any empirical evidence. He just sees that the tapets fail, or did fail. We all see this. The rest of all his "Sherlock Holmes" gaming is plain bullocks. Something goes wrong at Guzzi/Aprilia/Piaggio, that's beyond question. But to look at two versions of a whatever, public manual and search there for different identifiers and then, based on these findings, write or better fabulate about "I have found evidence of bad engineering" is more than stupid. Heck, you know, at Guzzi they certainly don't care about all those Greg Fields and C.ie out there. Nevertheless, I at least feel offended, maybe others as well. Ride on, too ! ...and off for China

Paul, do you think it's important to be a 4V owner to see whether a certain argumentation makes sense or not? Or whether it's fair or not? I always thought for this purpose it was just enough to have all his valves at the right place. I hope you can agree on that. Hubert

Or a problem with his new PCIII USB. Map mismatch probably. Edit: of course that's nonsense, sorry. In that case the rear wheel would have been found in front of the bike, not behind it.

I have no evidence that they were not cast iron. Why should they not make it from cast iron? That's common practice. Tappets, camshafts, things like that. Cast iron is not always that what you usually get from cheap china toys. Nevertheless, in a shop or parts or "agent only" manual you will of course always find the same name: cast iron. Casting and heat treatment technologies nowadays can produce nearly everything you want. You should search for figures like 1.1120 or 1.6570 and compare them to 0.7060 / EN-JS 1060 or the like. Something like that is written on the drawings. When everything is ready, drawings released, tools started, plant planned, suppliers choosen, all these formalities done, then the "Bureau of Technical Documentation" (just call it what you like) starts its work, writing shop manuals, user manuals, parts catalogues and so on. Normaly they do this job only once and with as less effort as possible. They do all but care about cast iron or cast steel or steel or peanut butter. BTW, can you have a look in the Centauro/Daytona/4V manuals after these pieces of evidence? For blaming any engineer at Guzzi or Aprilia for eventually having done a bad job, and for doing this on an international and publical forum like this, at least in my opinion it needs a bit more skills and facts than just comparing two versions of an english part manual, or even being employed at the home of Guzziology or "knowing" Dr.John (who's nimbus might also be well discussed btw.) Hubert Edit: Because you've asked for it: I don't think engineers are above all faults. But for an engineer life normaly is not too difficult - as long as he remembers the magical question: "Are the parts all up to spec?" Another good one is:"You can show me that your assembly line is capable?" That's it. Something different is sitting in front of a blank CAD screen - but for this annoyance you're in most cases acceptably paid.
