Using Guzziology's table of Megacycle/ Norris specs, it appears the progression to the hottest is: (620-) 3 -> 9 -> 10 -> 11 -> 8 -> 7 The P3 looks to have significantly longer duration (20º more intake, 18º more exhaust [276ºI/274ºE] and only 0.004" more lift [0.303"] than the 1064 Sport cam. So, we might say the P3 is a bit "hotter" than a 1064 Sport cam. All of the Megacycle cams have higher lift than the 1064 Sport or P3 cams. Duration numbers place the two Guzzi cams before and after the 620-10, realizing the 620-10 has higher lift than the P3 [0.335"). But where the SS2 and SS3 compare depends on the actual specs. EDIT[19 Oct 2016]: I found this technical section on the Raceco website. Looks like it would be good to archive this while the Raceco site is still supported. http://www.raceco.com/technical.html#ss2

That would have been a sight!!

Hmmm - too cool. A perfect compliment to my high-zoot *coffee maker* ? And that funky device at the right of the photo . . . *push-rod motorcycle analog music input support system*?

How cool is that? I was pretty stunned when this young lad decided to get a motorbike, then started riding with the *usual suspects*, then caféd a V7 Stone. (29 yrs old). Where do these kids get these crazy ideas? Haha - your time is comin', czakky!

Oh, man . . . I totally missed this! ("married off" the oldest boy this weekend) . . . You guys are great! I'm entering that ex officio point in life that it will surprise no one that I have an old Guzzi. What may surprise them is that it's a Tried-and-True RedFrame Sport! (Although I can't stop thinking about a black Cali Vintage . . . ) Gonna have to start wearing my matching *race* leathers more just play the part fully up! Cheers, everyone!

"The nasty bubbling engine paint. The engine cases are the worst, but I can see it starting to spread to the transmission. I’ve started stripping the paint, and now I'm thinking about stripping the tranny too – and going with a smooth (not textured) satin black finish." Same finish on the rear drive, no? It will only be a matter of time then . . .

Serious V11 Brain Surgeons! I am trying to catch up!

I griped about buying my V11, new, from a dealer 125 miles away, but he put it in my driveway from an enclosed trailer. The Lovely Wife wrote the check. I still have them both. (Well done, n-f ! )

Sweet! That paint defies photography (as many Guzzi do!) Those two bike look fabulous together!

Wait-wait-wait . . . I see the Norge in the profile and the pictures, but what's with the 1100 Sport-i? Funky, extra cousin? Neighbor's bike? Honorable mention?

wow . . . Gary Moore . . . iconic! thanks for that, brl !

I can locate Settings -> Extras -> Value Logging (CSV) by selecting "Preferences" from clicking on the GuzziDiag Version, but cannot seem to get further to create or see the TPS graph? ____________________________________________________________________________________________________________

a) Have you checked and confirmed if the TPS is defective? With GuzziDiag you can perform a fast but very reliable check if something is amiss without touching the TPS itself. Select Diagram in the View section and slowly open and close the throttle. The resulting curve should be smooth and consistent with a knee at 30°, beginning where the TPS has a different resistance curve. b&c) The PF3C used by Ducati is the same one as on Guzzis. Going by the curve shown by Cycleworks this is the one you need. d) You can use any TPS which can be fastened to the throttle body. If it has a different curve then the TPS lookup table in the BIN has to be changed so that the voltage delivered by the TPS at all openings corresponds to the values in that table. Most of what needs to be known to understand the TPS operation was already explained here: http://archive.guzzitech.com/HD-TPS-Jeff_B.html Below picture shows the TPS lookup table from a 15M. The lower table is not part of the BIN, it's just a calculated table to show the voltages corresponding to degrees with a PF3C. Adapting the TPS lookup table to TPS with a different curve is quite simple. Use the curve formula of the TPS and calculate a table with corresponding degrees and voltage breakpoints. Change the values in the TPS lookup table accordingly and it's done. Cheers Meinolf I am attempting to produce this table for my Sport with guzzidiag and my *dubious* HD TPS. While I am connected and a window opens from selecting "diagrams" from "view", I cannot seem to produce this table of values. What am I missing, please?

I see that czakky's reference to Dave Richardson's Guzziology has several sections devoted to cams including a reference section on the Megacycle cams. While the duration numbers are the same as the Mike Rich numbers, the lifts are not (over 0.400"). All the lifts in Guzziology agree with the Megacycle Cam .pdf. All are over 0.300", but not over 0.400" as Rich lists. *Difference in valve lash?* As to ScuRoo's original post, "Why not a 620-11 for a V11?" 1064cc/Sport cam: 0.298" lift / ~256º duration (exhaust is likely shorter) 620-11 Megacycle: 0.360" lift / 282º duration With my very limited knowledge of high lift/ high duration cams, isn't it all about the heavy breathing at the highest rev range? In that case, It seems the "Crane" derived 1064/Sport cam is pretty well optimized for the usual tasks of a sporting street bike. That said, I'd just love to listen to a V11 with a 620-11 at it's angry idle. Then on the howl!

Moto Guzzi, admittedly, has a really nice line of motorbikes right now, from a whole series of excellent V7, now the delightfully finished V9, Stelvio, Norge, and a whole passel of 1400 cruisers. I suppose the Griso represents the sport-oriented big block? Curious how we used to speak of ranges of Guzzi by their frames: Carcano's loop frame, Tonti's . . . uh, Tonti frame, and the SpineFrame. Since then, no one seems to be focused on the frame anymore. *Maybe* what Guzzi "needs" is the next generation sporting frame for the modern bigblock. And that 3 cylinder diesel military bike that will replace both the Stelvio and my Jeep wrangler . . .

Well done, guys! Just to restate and share what I learned here about tuning with fork oils, not all "5 wt" or "10 wt" fork oil is the same. Thinner oils do seem to flow better through the Marzocchi's tight damping. See Peter Verdone's great work on listing many common oils using centiStokes@100ºC (a much more accurate unit than "# weight" ): http://www.peterverdone.com/archive/lowspeed.htm (I have had good results with BelRay HV1 5W that I understand comes in at 19.50 cST)

Thanks, czakky! Looks like all of the Sport 1100/ 1100 Sport-i and V11 cams have the same part number, according to Dave Richardson (a solid and reliable source He states the 1064 sport cam lift is 0.298". As Richardson says, cam specs are influenced by valve lash. Is this why the Megacycle lift specs and the Mike Rich specs differ so much? Nonetheless, a 620-11 (and several aftermarket cams) look like they will require some careful head work.

Also, it is notable that Mike Rich specifies particular head work for cams beyond the 620-9, and also does not reference the 620-11. The reason I'm asking for data on the stock cam is to better get a "baseline" relative to the 620-11 (and other aftermarket cams). I *suspect/expect* that the V11 cam is already quite a bit more aggressive than the SP1000. But, if we don't know the lift and the specifications of stock cams, it's hard to compare . . .

It doesn't look like the Mike Rich lift agrees with the Megacycle numbers even though they both claim to be measuring duration at 1,0mm (if I'm reading the Guzzi manual correctly, they are measuring intake at 1,0mm and exhaust at 1,5mm.)

I guess they went almost 20 years between LeMans (1992-2002) the last time, so maybe we're not yet due . . . 100th Anniversary LeMans?

EICMA in Milan has long been a place that Moto Guzzi teases us with tempting siren songs of Moto Guzzis to come. I have a picture cut from a magazine of the black, RedFrame V11 sport they showed in 1997. It was 2000 before I could get mine! What siren song will they sing to us this year? There has been no LeMans since 2004 . . .

I recall that the original Sport 1100 cam was developed in cooperation with Crane Cams. Are the Sport 1100, 1100 Sport-i, and V11 cams all the same? (EDIT [19 Oct 2016]: they are all 1064cc Wittner/Crane Sport cams 3705 3305)

Hoarder. Takes one to know one. I'm wearing mine around my neck as a talisman. There is all kinds of spooky-badness to be kept at bay by well-made things done-up in zinc chromate . . .

Hey! I resemble that remark!
