Started my "shakedown/prep" for the XXI South'n SpineRaid, about two months out (metric: 8,6 weeks ). Sixty mile/97 km warm-up ride (aka: get beer). Onto the lift and drop motoroil and gearbox oil. No metal fuzz on the engine drain plug (6300 miles/ 10.000 km); the "usual" fuzz on the gearbox plug (15,000 miles/24.000 km). Out with the oil filter through the access cover, remove the label from the new WIX filter and see that the old filter gasket came out with the old filter. Fresh RedlIne 20W-50 after being certain the filter access cover screwed back on perfectly. Took time to troubleshoot the (lately) dodgy Neutral Switch. Fitted a new crush washer (to space the switch correctly on the shift plate) and adjusted the external shift mechanism connecting rod so the lever clears the Frame Side Plate/"stiletto" on the downstroke. On to service all major electrical grounds and battery terminals with CRC Electronics Cleaner® and Caig DeOxit®. Yeah, that's a French medical graduated cylinder. Yeah, I use that to add 850.0 ml to the gearbox. Yeah, I know that's bogus. I even heated the gear oil to 120ºF/ 49ºC for a clean pour. Next: Decent Tune-up . . .

This might help someone. (and apologies if it has already been noted) I had carefully set the TPS by the book and the bike (2002 LeMans) suffered from surging when hot and abrupt on/off throttle transition and slight pinking at full throttle. The surging and throttle transition made the bike frustrating to ride. I retested the TPS it was still 160mV with throttle plate closed = not significantly different than where I'd set it last year. I then noticed that when the throttle was pulled open that the first motion was to take up throttle shaft wear. (to check for wear, grab the throttle shaft nut under the throttle body and move it side to side. The right side has more play that the left, perhaps because of the return spring. There are rubber seals on the shafts but may be unable to compensate for the wear or have failed after 23 years.) In one of the TPS discussions KiwiRoy suggested that because the voltage increase with rotation is not linear that the goal of setting the TPS was not so much to achieve precisely 150mV (or 157mV), but to make sure the setting was on the tail of voltage increase. I pictured the voltage increase as a curve similar to exponential growth with 150mV somewhere close to the baseline suggesting that at 150mV the computer can sense the TPS but is not yet altering fuel settings. After setting the TPS the manual states that throttle plate angle should be set to 3-3.5 degrees. I wondered how to do this because I don't have Guzzidiag computer setup, but another post (I forget who posted) stated that throttle plate angle at idle corresponded to 470-480mV. Another post stated that instructions for installing a new mixture map that the idle throttle stop should be set at exactly 475mV. My idle stop was at 311mV so I decided to experiment with changing it. I set the TPS to show about 470mV just as the throttle starts to lift off the idle stop. As the throttle linkage is pulled the first movement takes up play in the worn throttle shaft and the mV increases. All the play is taken up and the throttle starts to open at about 470mV but my TPS reads about 420mV when the spring holds the throttle against the idle stop. (differing amounts of wear should result in different idle stop mV) With the throttle plate fully closed (as in setting by the book) the TPS shows about 220mV. I then balanced throttle bodies side to side. The result is dramatic! There is no hint of surging even at low rpm and low speed and the harsh on/off throttle transition is mostly gone. There is no pinking. It has really improved the bike. Yes, I know there someone has posted a tutorial for replacing throttle shaft bushings. I have even bought new bushings and seals and will get to it eventually, but I am very happy with the way the bike runs now.

LaGrasta - this makes sense, but I wasn't able to find the instructions at electrosport. Do you run it through a fuse or circuit breaker like Docc suggests? Tomchi, AudioMick and Docc - I do recall that the ground was to attach to the engine. Perhaps my memory confused this with a power wire like LaGrasta describes? I will reroute it when I install the new regulator. Docc - I tried to find Caig Deoxit a couple years ago and looks like it is mail order only for me. The connectors are bright and shiny. Speedfrog - the replacement regulator is arriving today so maybe mosfet next time. The description of the electrosport regulator also looked good. To everyone - I really appreciate your quick and detailed help. Your knowledge and willingness to help are impressive. Thank you.

...sounds like someone loves his V11. 🙌

Very nice, and easy to handle too. I might need to upgrade. Right now I have a Walmart plastic graduated liter measuring cup.

Nothing today, but... The day before yesterday on the V11, got the forks and front wheel back in. About time, too... Yesterday on the V35 Imola rode about 110 km. I really didn't want to, honest, but the battery needed charging... On the Breva, disconnected the battery. It isn't going to be ridden for about 4 weeks, minimum. If the battery is not disconnected, that is long enough to completely flatten it.

Yeah , when you realize what is / is not in this switch then you conclude they are charging about $90 too much. It is literally a door jamb switch. That reminds me , I will look through my Standard Ignition Buyer's Guide and see what I can find.

Glad that you avoided that switch $!

I couldn't measure how little the plunger moves to close the switch, but is has to be less than 0.004" (maybe as little as 0.002"). "A skosh " . . . So, my circuit tested good (light on when wire-end connector grounded, off when open), and the switch tested good (considering the wee skosh of movement to actuate). So, I am happy, yet surprised, to report a new crush washer was the solution. For now. Some things don't stay fixed. I also found my shift lever striking the lower hook of the Frame Side Plate/ "Stiletto " on the downstroke. Lengthened the connector rod one full turn of the rear rose/Heim joint. As noted, "Some things don't stay fixed. "

Just trying to nip things in the bud.

As a replacement for your stock regulator, consider upgrading to a Mosfet type reg. Shindengen Mosfet regs in particular are the bees knees of motorcycle regulators. https://roadstercycle.com/Shindengen Mosfet Regulator about.htm

The TPS voltage change is not an exponential curve but a straight line. Depending on the model of TPS it is either a dead straight line from zero degrees to 87 or a straight line until a break point at 30 deg then another straight line from there. So either the linier or non linier version. Just change the throttle bushes and seals. Delaying replacing the coated bushes will just end up wearing the throttle shafts and then the TB's are scrap unless you have the kind of access to machinery I have. Use the Viton seals now available via CA cycleworks as they will be better than the yamaha seals I'm sure. Phil

fully unacceptable. I'm sure your Guzzi dies of embaressment every time you use it.

thanks for the clarification.

I think we should be sourcing a "compatible part" instead of the Gu$$i part. I feel certain someone posted this switch with a male spade connector (instead of the "T-disc"). Yet, I cannot find it . . .

. [Wasn’t sure if this should go in to “travel, “events,” “banter,” or what subthread, but put it here. Mods can move if I chose incorrectly.] =============== Over the years of SSR's, we have invited attendees to come visit us sometime here at the top of Virginia. Eric <pressureangle> emailed us and wondered if the offer was still open. Hmmmmm. Unable to come up with any credible excuses for “no,” we said, “of course.” Eric did mention that he had two traveling companions. I heard — apparently what I wanted to hear — that one was a woman. The three arrived day before yesterday ... Two beemerists and a Harley. [Really, Eric. Puhleeze.] Wonder which the lady is on? I’m going with one of the GS’s. But, I ruled out this GS as, while I agree with the sticker's sentiment, I saw Eric pull in on it. Hmmmmm. What about this one? What tag is that? Ah, Quebec Très intéressant. Perhaps she looks like Marianne Fortier in leathers; yes, undoubtedly. Kathi, I can explain ... uhm; better not. But what if the lady rides the Harley from Maine? Never been much into knives, tassels, and tats, but one should be openminded about such things. As, however, you may see from supper, no Marianne Fortier stand-in or biker-ette. Sigh. But Denys and Eric (#2) were great bubbas. After the meal — and more than a wee bit of wine, beer, grappa, bourbon, and Fernet-Branca, Eric 2 got into the swing of things! As always, of course, morning brings the reckoning … Still, I thought Kathi was a bit too sad at E2's departure … But, off they went … Eric rode caboose to ensure no stragglers … They spent last night at the Fancy Gap/BRP KOA; E2 seems to have transferred his hangover to Denys! Not sure where the trio is today … will let Eric pick it up from here. We had a great time and hope to see all three again. Bill

No, it was a strictly Prussian affair.

But was there mutton?

We made it to Asheville, tomorrow is Wheels Through Time motorcycle museum. Thanks to the Hagans for the hospital ity, and the many new flavors from around the world.

I recently got my drop-top coupé back from an extensive, fifteen week, repair. The absence caused me some interest in all of your comments and experiences. Just back from a weekend drive of nearly 200 miles/ 322km, I so enjoyed the engagement offered by the top-down experience. At times, a pungent aroma would fill the cabin and I would look about for the fresh-mown hay field; same sensory intensity crossing creeks and rivers on my way. Much like what we know of motorcycling. In fairness, I wore an earplug in the inboard ear for much of the trip as the buffeting can be annoying. Also, the option of top up and A/C is ever present and available. Yet, all-in-all, I always come away thinking (and I quote from the Clint Eastwood movie Gran Torino), "Ain't she sweet?"
