Rather than go to that trouble, see if you can connect to one of your V11 and get GuzziDiag to display selected measurements. Try to follow the steps in the Basic Tutorial. It shows the step-by-step: Once connected, it will be quite interesting to see what your CO Fuel Trim is . . .

I would have to strongly recommend you source the pawl spring (from @Scud) as well. It is so unlikely the "Detent Roller" spring shown in the Stein-Dinse link is the problem . . .

GuzziDiag V0.60 -> "Windows" Don't worry about any of the 'IAW" software for now . . .

Open that link to the von-der-salierberg page and follow the instructions in the Basic Tutirorial. You download the software based upon what operating system you are using (Windows). At about the sixth step, you will see where to "select your motorcycle (model)."

So great, Jon! Like I said, you (and your V11) are in the right place. FYI, those TYCO relays are among the most failure prone relays ever to ride in a V11. DigiKey is a worldwide electronics distributor (not sure your actual location). Currently, the Best (micro-ISO) Relay is probably the Picker Components high current selection. (Yes, you can put the same 5-pin relay in all five positions ) . . . https://www.digikey.com/en/products/detail/picker-components/PC782-1C-12S-R-X/12352866 Data Sheet There were "variations" in the V11 line over the course of production, 1999-2005. Knowing the tenth character in your VIN and the "model" (LeMans, Sport, Rosso Corsa, etc) will help you, immensely, with various tasks and parts selection . . . Best! docc

Hi, Jon! You are in the world's best place to get to know your V11. Your ECU is likely fine. Let's start with fuses and relays (under the seat). First, look at Fuse#2 (from the front). Next, carefully give Relays #4 and #5 a wiggle and firm press (maybe even unseat them slightly and press them firmly back in). Make note of the make/model of your relays and post back . . . Best to you and welcome! docc

Are you speaking of the corroded coil output? Yes, it cleaned up, but the wire end had corroded apart and had to be replaced. And, yes, that nasty hiccup was much improved!

One can hope . . . Best wishes to @FreyZI . . . "Life" can get >busy< . . .

Last visit from @FreyZI was about three months ago. Last major activity on this project was closer to a year ago (?) . . . So, "dunno" . . . mySport would look right-sporting with one. . . .

I declare this drift "back on topic" . . .

For purposes of clarity, "Return" spring (left) / "Detent Roller" spring (right): [Above: the difference in spring shape after about 90,000 miles/145.000 km] [Below] - Top: 64,000 mile factory pawl spring; Middle: new factory spring; Bottom: ChuckScud Superspring:

I will report back on the results of installing fresh, correct O-rings on the Air Bypass Screws. There are many (many) culprits to exorcise that contribute to the V11 sub-4000 rpm hiccup/cough. As, @Tomchri has said, " the TPS is VERY important ." Yet, one of the most maddening hiccup/cough sources to contribute to my (ongoing) madness: a very slightly loose vacuum tap and dried out rubber cap: (Yes. It made THAT much difference. ) And, yep, sometimes those superficial intake rubber cracks aren't just on the surface: In case we forget that "Ignition" issues can send us down the "Fuel/Air/Map" rabbit holes, this coil -> ignition wire connection failure took a long time to reveal itself . . .

The first one will display, if you "hot link" it. The others are fb, so no. Just links that won't display.

I wish those images would display - would love to see them. Here are a couple I could produce:

" IPA Time" , indeed !

For certain, the V11 is exceptionally sensitive to even very minor intake leaks as well as exhaust leaks. These can add up to a maddening crusade to hunt down and eradicate idle issues and the nefarious sub-4000 rpm cough/hiccup. Ever the Beta Tester, and afflicted with a painfully inquisitive mind , I removed my Air Bypass Screws for cleaning this Decent Tune-up : Yep, they were really sooty and nasty. Far worse than this "representative image" shows: Then I got the clever idea that the 20+ year old O-rings could be suspect (green, left: below). One, especially, looks deformed and damaged. So, I locally sourced Viton O-rings in "Standard" size #008. They look (and measure) a bit undersize (black, right: below): After waiting at a crowded counter at my expert rubber&gasket resource (along with folks repairing bulldozers and well drilling equipment ), the good man sizes the wee O-ring as metric 4mm I.D. x 2mm cross section. The #008 is indeed a bit undersize. He figures Viton is the right choice and orders them for me. (I had him get a dozen so the well drillers would let me live) and asked him what the OEM green O-rings could be. He figured EPR (or EPDM) as used with refrigerant, but no way they could have lasted all this time (me: "thinking" ). So, what are the OEM green air bypass screw O-rings? Nitrile? And, isn't it coming time these hidden leak sources might start contributing to our madness if undetected?

With this latest offer to produce a batch, @Pressureangle, do you want a post here to edit/update the sign-up list like was done for the Latest Last Batch of Chuck-made Shift Extenders? I see three in the last 4 hours . .

Too cool, @Steve S ! I have long wondered how many V11 have benefited from your stewardship. Regarding the OE front brake pads, Tim at CadreCycle in Cincinnati, Ohio/USA, tells me he has three sets of these GU01654630 at $73.00US. Each V11 uses two sets. This morning OPP Racing sent me a tracking number for the order I made last night. Another member here tells me he has used OPP extensively for Brembo components and parts.

Nero Corsa from @Steve S

Even the Öhlins V11 look to be 2-pin . . .

I don't know where I got the idea that the front calipers changed to a single pin during the V11 series. A 2003 LeMans is definitely a "later" V11. [edit]: Every image of a V11 I can find, through the 2004 Corsas and the 2004 Scura R, have the same 2-pin front calipers.

Thanks! Here is the detail from my OPP invoice: Brembo OE Brake Pad Set, Ferit I-D 450FF Pad Kit for 20.6800.xx / 20.9230.xx Caliper, Shape M - 107670810 [edit]: our early 2-pin calipers (didn't the V11 change to single pin calipers later?) look like these P4 34/30 20.6800: [Yet, I can't tell the difference from this 20.9230:

These Brembo "sinter" pads (red backing) are what is available from MG Cycle for the front. The rear I got from them recently is "carbon ceramic" (blue backing) that I have run before.

Thanks, again, @Speedfrog. I made an order from OPP Racing and will hope for the best. I just cannot run these "sinter" pads.
