It's a prototype Ducati by Mariani according to "Dogwalker"

This is the cut through - imagine this timing gear as the front look of a new 8V SB Guzzi mill  :o  Would only take new heads/pistons and a new timing cover.


That is a cool concept with a nod to Ducati's history with bevel driven cams. It looks like the concept is using traditional valve springs. If they are going to use bevel driven cams it seems they should stick with Desmodromic cams.

Speaking of elegant and beautiful.. look at the casting for the 4V small block valve mechanism.. ;-T




 :+1  ;-T
One of many things I like about the 8V SB's  The engine itself look so much better than it's contemporary SB mills. It has some competision now from the new V7 line - that mill looks cool too - but lacks the extra valves  ;)

That bevel drive is really expensive compared to a chain or belt drive.
The latest chain drive MG is a very good design, IMHO. Water cooling is inevitable to meet emission regulations, and increase power with reduced fuel consumption.
As said earlier, Piaggio Group chief engineer already stated that air cooled engine will survive the next emissions regulations (Euro-4 and Euro-5 have already been decided), even with a pratical limitation to 100 hp/l.
This means that it would be possible to have an emission compliant small block 800cc, air-cooled, engine, with 80hp.
So, it will be possible to do all the middleweight range, with the exception of the supersport, with one engine (enduro/crossover, sport naked,  touring, supermotard...), just see what BMW and Ducati does with their 800cc engines of similar prestations, and with the advantage that the Guzzi engine would also be suitable, as is,  for vintage and custom/cruiser bikes.
Chain, or belt, drive are less expensive than bevel drive, but they require redesigning the basement, cause they must be placed behind the cylinders. In front, they are a too big aerodynamic obstacle.
Bevel drive, as said, besides being beautiful and technically attractive, requires only the redesign of the heads and the front cover of the engine.
So, "really expensive", what does it means for a mass produced engine, with components purchased in blocks of thousands? 50 Euros for engine? It could easily turn to be a saving. Actually, we see that bevel drive is used in the Kawasaki W800, that is not an expensive bike, for aestetic reasons only.

In another thread we read that MG is moving to liquid cooling. Actions speak louder than words, so that is how I take the pronouncements of an engineer.
You mention re-designing the "basement" as if that would only be neccessary for chain or belt. Doing so for a bevel drive will be much more complicated, and if said bevel drive can be made at the front, so can chain and belt.
And really expensive does apply to bevel drive; there many more parts, some of them precision machined and adjusted, while none of that is needed for belt or chain. The Kawa engine uses one shaft and because they do use a shaft drive doesn't mean it's not expensive.

Really, no. If you know the disposition of the SB engine placing a pair of shafts and bevel gears in front of the engine, does not require any redesign of the block.

and if said bevel drive can be made at the front, so can chain and belt.
In fact the chain has been placed behind the cylinders in the new 4V. Chains and belts requires a box to contain them, placing it right in front of the cylinders means to greatly reduce the cooling. This does not apply, of course, to the shaft drive.

And really expensive does apply to bevel drive; there many more parts, some of them precision machined and adjusted, while none of that is needed for belt or chain. The Kawa engine uses one shaft and because they do use a shaft drive doesn't mean it's not expensive.
A Bevel drive has many more parts than a chain drive? How many?
And, so I asked, what does it means "really expensive"? have you an idea? I can see that the W800 use it, for aestetic reasons only, and it's not an expensive bike. So, how many $ for engine, for a mass produced engine?

A bevel drive has precision parts. Spiral bevel gears must be hobbed, while sprockets for chain and belts can be made of sintered material. Bevel gears require precision mounting and adjustment, while chains and belts do not. All of that addds up to "really expensive".
I very much doubt anything can be done to the existing block without a re-design, for certain a bevel drive could not be bolted onto existing structure. Chains and belts can easily be run through passages created in existing parts, much the like we see pushrods running within the cylinder casting.

I know, thanks, so I asked: what does it means "really expensive"? have you an idea? How many $ for engine, for a mass produced engine? Since the existance of bevel drived bikes in the middle range market seems to demonstrate that producing them is not impossible, it would be interesting to know before to say it is too expensive to be produced.

Bevel gears require precision mounting and adjustment, while chains and belts do not.
Really? That's new. I had always thought that timing adjustement requires precision for chains and belts too.

I very much doubt anything can be done to the existing block without a re-design,  for certain a bevel drive could not be bolted onto existing structure.
Really? Given that the bevel gear would be placed on the head of the existing camshaft, where once there was the distributor, why not?

Chains and belts can easily be run through passages created in existing parts, much the like we see pushrods running within the cylinder casting.
Since this would require to put a pair of sprockets inside the engine (a very compact and "crowded" one like the SB), where today there is none, I do not see it that simple.

Spiral bevel gears *are* very expensive to produce, and the manufacturing tolerance is much fussier. If Honda (or even Kawasaki) with their thousands of units produced were doing it, you might have an argument. With Guzzi's few hundred (in a good year) units, it would add *considerably* to the cost, IMHO. Just sayin..

The W800 engine is used only in the W800, that is produced in some thousands per year.
Guzzi SB are produced in some thousands per year (now that the line is composed with V7 and Nevada only. As i Said, an 80HP SB would be good to made some other model too).
It seems quite comparable to me.

The precision mounting and adjustment of bevel gears is in addition to the timing requirement. Which model Guzzi engine had the distibutor mounted on the camshaft? None I know of.
You obvioulsy know little about gear trains, so get yourself educated and get back to us when you have.

I don't see a distributor in the photos. Can you try again?

Here's a photo of a Ducati timing chest-not much is similar to the MG, starting with the big ball bearing supporting the crankshaft, which drives the gear train.
As I stated earlier, your knowledge of gear trains is far from complete.

Then the bevel gear can not be put there for a matter of semantics? Must be a new field of mechanics.

Sorry, but that photo is not an argument. You can see another interpretation of the same subject in Mariani's prototype above. There is no requirement for a bevel gear to be attached directly to the crankshaft. Is only one of the possible choices.

Sematics it is not. You don't understand the basic definitions of engine architecture.
But you were quite happy to post photos in support of your erroneous opinion.

I thought you might have understood what I was talking about anyway. Unfortunately, it seems that dialectical questions continue to interest you more than mechanical ones.

So, can you tell me a reason for which a bevel gear can not be placed there (the fact that in an Ducati engine was in another place, is not a big reason)?

LMAO!  Thanks for that. Its funny, all the talk of bevel drives, water cooling etc...I like Guzzi's because they are dead simple, easy to work on, and easy to become passionate about.  Guess I'm just old school that way. I'd take a Pratt&Whitney R985 over a PT6A-67 anyday! 

Pushrod actuated valves and aircooling has worked for a lot of years.  I'm all about improving things, but there is something to be said for proven designs that work.  And that are economical to modify...LOL

Wow is that a cool pic or what ;-T  On a serious note though, the valve train on the Lario is its weak point The SB mill was originally designed for 2V heads. Hence the cam lobe, tappet issues managing now twice the springs and valve assemblies. Some kind of OHC design would fix the weakness once and for all. In spite of this I sure like the 8V SB's - and consider it a challenge to make them last  :)

That is a good point Brian.  Just my opinion, but I think the design is sound, I believe it was more the materials that were used to assemble the original bikes that was the problem.  Cam wear and valve breakage caused by increased spring pressure, which was necessary to stop valve float at high rpm.  To be frank, what I'm doing on my project is really only part of a fix.  After all, I'm going to be limited on the RPM to 7600, and to really make power I should be turning up to 9000 or so.  I am attempting to make a reliable engine though, so I will keep the rpm's down.  I think with the Ferrea super alloy valves I'm installing, the DLC coating on the cam and lifters, and bronze guides in the heads, I will be ok.  I guess we will see...LOL  I have all the parts ordered now, its just a matter of waiting for them to arrive, and then shipping out the heads, cam and lifters for work.   ;-T ;-T ;-T

I guess you are doing a "Kevin" - at least on the valve train  ;D  Your bike will likely last into the next millenium  ;-T
Can't wait to hear the first ride report  ;-T ...and yes, if Guzzi had used better materials, and the wider cam from the start, they would have had a lot less issues IMHO, perhaps even as little as other later SB's, but in the middle of the remediation process it looked like Guzzi just dropped the ball and ran away from the 8V SB's. Sad IMO.

Well, things are proceeding apace with the project.  The main thing that takes time is the shipping of parts from Italy and Germany.  At this point I have located all the parts necessary to complete the conversion, I have to wait until they arrive, then send the heads off for new bronze guides, send the cam and lifters in for DLC coating, complete the initial dyno run with the stock heads etc...
I thought I would post a few pictures of the progress to this point.  Tonight I removed the right hand head and cylinder in order to weigh the existing piston.  I removed the exhaust, intake, and fuel tank to start with.

There are two issues that have come up, both managable.  The original cylinder base studs are too short for the 4 valve configuration.   You can see that two of the outboard studs don't even come through the head.



Fortunately a cylinder stud kit for a Volkswagen Beetle has the exact length, diameter, and thread that I need.  10mm x 240mm, and 10mm x 214mm.  Both in a 1.5 thread per mm pitch.  The VW studs are chromemoly from CB performance, they should do the trick.

The other issue is that the stock rh head incorporates a cylinder temp sensor for the fuel injection computer.  I do not think this will be an issue with my new heads.  I have installed a re-flashed ECU from Todd at Guzzitech, and a Power Commander V with Autotune.  This lets me adjust the fueling based on what the O2 sensor is reading.  I am pretty sure the CHT input is not used anymore.  I will have to study up on that though.  Here you can see how the CHT sensor is mounted in the 2 valve head.

Great info Mike  ;-T

I needed a set of studs too a while back for a 750 8V project. At that time the ony way even Martin Hagemann could help me was selling me an additional used V75/4 crank case - happy for that today, as it turned into an additional mill later on  ;D

Great work and great info ;-T
