So, a V85TT without the tricker, more expensive V85 motor? The lesser V850 motor instead?

Oh, oh, okay. Sorry about the ox. A new model of the V7, come V850:

@fotoguzzi had a bin of Centauro parts he has been sharing . . .

Vibration in grips at 3k-5k RPM...any way to correct?
docc replied to VtwinStorm's topic in Technical Topics
Fresh Brembo pads, fluid bleed, and especially rotating and equalizing the piston action across all pistons in each caliper can work wonders on the brake feel. -

Hard to know if it was just not said rightly, heard wrongly, or something that actually does not apply to the V11 15M ECU. AFAIK, the V11 ECU have no "relearn" capability on any level. -

The only parameter my V11 ever "relearned" has been the undauntable effects of gravity. Otherwise, it's 15m ECU doesn't have that capability. Pretty sure that started with the next (W5AM?) ECU in 2006. -
To your point, "[What makes Guzzis quirky]?" It really is, JMO, that they require an immersed owner. No shop or tech can deliver it back to us fully capable. This would be like the veterinarian delivering our dog back to us spayed and dew claws removed. It remains to us to train and bond with this *animal* . . . What? The Guzzi is like a living, breathing, thinking animal? Compared to common machinery? Yes. We would not be the first to suppose such thinking . . . "A skittish motor-bike with a touch of blood in it is better than all the riding animals on earth, because of its logical extension of our faculties, and the hint, the provocation, to excess conferred by its honeyed untiring smoothness. Because Boa loves me, he gives me five more miles of speed than a stranger would get from him." – T. E. Lawrence

Early reports of grip vibration (along with reports of "twitchy" handling) on the RedFrame Sports likely led rather quickly to the V11 Longframe and wider rear wheel/tire with longer forks to attach the clip-ons above the top triple clamp. Then: ~ handlebars ~ . . . Seriously, for a RedFrame Sport: beyond performing, repeatedly, a meticulous Decent Tune-up, setting up the suspension with springs correct for your weight and settling on reliable tires/tire pressures will work wonders for your Sport's "feel." Otherwise, I would say the early Sport naturally feels more like a Fender P-bass through a Marshall amp in a concrete corner than a cello in the forest . . . -
If you have an aftermarket shift pedal, it will be harder to adjust the linkage so the shifter does not strike the frame side plate on the downstroke. Worth fettling the external shifter linkage and pivot bolt.

I had my (hefty) factory bar-end weight inserts machined to accept CRG bar-end mirrors and ditched the "stalk mirrors." Not to everyone's liking, but improved the felt vibration. Italian made ProGrip "Superbike" grips made it even better. Nothing really made the major difference until the effects of the Decent Tune-up took hold . . . -
That cam drive Garvey disassembled is absolutely incredible. It looked like two different size sprockets pinned together like a reduction drive. But noooooooooo! Too cool. Thanks, again, for the vid @ScuRoo !

That is such a wild, non-inutive concept. I could never get my mind wrapped around that. Garvey's Teaching Jig is fabulous. Such a good teacher, as well, IMO.

Holy cow! That is so geeky! I watched it beginning to end, paused, replayed parts, and took notes . . . Brian Garvey's explanation of secondary vibration (and the Formula 1 solutions) is stunningly clear. Even I get it (now)! When he put up the image of the timing gears from the Cosworth TJV10 (24:05), I grabbed a screen shot to remind myself part of why I would like Joe Caruso's gear set in my Sport. Elegance! (At 16:04, Garvey says, "You never turn an engine backwards." Why is that? Any engine?)

The combination of Scud's ChuckSuperSpring and LuckyPhil's Shift Improvement is stellar, as well as an extended shift arm. Grooming, adjusting, and greasing the foot pedal pivot bolt and the entire rear-set shift mechanism is definitely the place to start. The pivot bolt has a lock nut that allows it to be set for a bit of freeplay for the shifter , but not too loose. Make certain the pinch bolt on the gearbox arm is tight as are the lock nuts to the Heim/Rose joints. Adjust the connecting rod length so the pedal does not strike the frame side plate on the downstroke and the arms are parallel: If you take the side plate off for the spring and shift improvement, change the detent follower on the index wheel. Mine was notchy enough to cause stuck lever repeatedly, just like your symptoms. +1 with Steve S that a broken spring doesn't let the lever just pop back up and resume play.

I did not know that CMS-NL has parts for our V11! That is great news! They do not show Moto Guzzi or the V11 in their searches, but I entered the part number for the 2002 jewelled lamp panel and it brought up a page. "Expect up to six weeks delivery" usually means they are hoping to get it from the factory . . . https://www.cmsnl.com/products/lamp-panel_pggu02781101/

Quality valve stem caps are important! Make sure they have a seated O-ring and in no way depress the valve stem air release. Mine came from a Boeing 737 (aircraft content) . . .

The Legnano green Sport looks so capable and composed. While the triple, and especially its exhaust, looks like a pleated skirt from a Leonard Cohen song that you could cut your lip on. I mean, I like it, but I've cut my lip on pleated skirts before, too . . . . As we northern hemispherists enter the Season of Mice and Ice, we look forward to what you chaps are up to . . .
