What a beast!!

Good going! You don't have to change the map to set the CO, just must have an ECU interface tool of some sort. Your local Guzzi shop could check it in minutes. +1.75 on the air screws seems like a lot. I like a full turn to get stable idle in the heat of the US south. Now that the TPS has its baseline, don't be afraid to simply raise the idle with the set screw to where you want it. Best to balance at some rpm (2500+) and use the air screws to balance at idle. Every tune-up brings the parameters closer and closer/better and better!

The CO trim is set in the ECU with a software interface. Those guzzidiag guys are amazing. I'm thinking it can be done that way. Certainly, using an exhaust gas analyzer will give you the best results, but they're not common in most people's pile of tools. Using the original Moto Guzzi diagnostic tool (Axone) and also the software interface VDSTS, we found my CO trim set to minus 27 (an arbitrary scale, but very lean). Zeroing the CO on the scale really improved my running. (We confirmed the result with an exhaust analyzer as well). Again, it's my understanding you can do this with guzzidiag as well as comparing the rpm seen by the ECU to what you see on your tach. However, the air bleed screws really do not set the CO (AFAIK).

So, extrapolating with some linearity, and rounding off a bit, there would have been some 6,600 RedFrames built 1999-2001 (probably including the 600 Rosso Mandello with black "RedFrames") and under 1,000 imported into the US. Pure speculation, mind you . . .

Do you have a way to check the CO on the ECU's "dashboard?" Make sure it's not ridiculously leaned out. Then you can also be certain your tach and the ECU are seeing the same rpm before setting the idle.

Does it get a lot of miles, or sit a lot? Dropped right in with no changes to the hold down or the cables?

If you guys go to Frenchies, I want in on this! I'll buy the first round!! South'n Beer&Grouper Raid!

Trailer's not big enough for your entire collection of sweet, bright red Italian motorbikes? :race:

That's an excellent explanation. The recall document is US specific. Were early V11 gearboxes also "recalled" in other countries? Interesting, that from October 1999 to April 2001 (probably all of 2000 V11 production and half of the 2001 imports), there were only 680 units imported to the US. I'm thinking there is nothing quite linear about Things Italian, so I'm reluctant to extrapolate . . . but I want to . . .

The 2000 Sport had a (rare) three year warranty. My dealer, 125 miles away, developed the confidence that I could install the parts and return the defective to him : Win-win! I hope he doesn't mind my broadcasting this world-wide, but if you ever meet Ben Curlin give him a big solid handshake as you've just met a very fine gentleman and an excellent person. I'll always admire the way he stood by me as a customer and an enthusiast in spite of the hassles MGNA threw his way. Service way beyond the call of duty!

Guzzi with parts off a milking machine . . . now this is coming together!

Ok - that's good stuff! I'm on my third speedo. The first was replaced under warranty for wagging at highway speeds (just under 27,000 miles) and the second lost it's trip odometer (44,000 miles). Several bevel drives are in the mix there, too! I reckon there's a SpeedHut in my future! (Just turned 20,000 miles on this 3rd Veglia speedo). The original gearbox might have run it's pawl spring forever, but not it's "sliding dogs." The warranty replacement gearbox (after ~30,000 miles/ 3 years) popped its pawl spring after 4 years/27,000 miles. The replacement gearbox was 2002 mfg which (I believe) is over-represented in the spring failures. 38,000 miles on that spring now, but let's pretend, for VooDoo purposes, that we never had this conversation. (I see lots of rounding error in those numbers, but you get the idea!)

Ok, I get that. Like how the seals in a fork also have a "dust seal?" You guys are so kind to make me feel better about paying $22 for a $7 part . . .

Hmmm, mine are all sealed. I'm not saying they come with grease in them, just that they're sealed . . .

We've long talked about production numbers of the various V11. While the Workshop Manual declares that each year begins with serial number 111111, the date range of the early gearbox recall mystifies me. (V11 Recall Notices in FileShare): "From 2000 models xxx111929 to 2001 models xxx114435" Based on the first 2001 being 111111, that would be 3,325 of the 2001 models alone with no clear indication the last 2000 serial number. (my Sport was constructed March 2000 at # 112641). Yet, the recall notice specifies that 100% of the range is affected and that entails "680 units." How in the world does that add up? They don't number sequentially?

For sure, they had $7 Chinese bearings, but this was their "name brand" (Federal Mogul) product at $22. I'll be keeping an eye on it. Impatience got the best of me and made me proud to have the bike back on the road in under 30 hours after the failure. Once again, I feel lucky. Stupid, but lucky.

I'm pretty impressed it made it that far. I'm less impressed with myself that I didn't see it coming. In the past, I've made a habit of lifting the seal cover and adding a bit of high quality grease. I didn't do that with this replacement since I've bent and munted the seals sometimes before. Figured I'd leave well enough alone this time. Still trying to learn that axiom, "If it ain't broke, don't fix it!"

Carl, you're a respected member of this, and all, Guzzi community. Even if you have foisted off The Bugswatter on some unsuspecting Coloradan.

Exactly. The company behind it usually is one of the well knowns like FAG or INA anyway. Way more important is the right spacer length. You checked this probably, did you? Hubert Oh, yes. Some years ago. The first bearing was replaced under 15,000 miles/24.000 km under warranty (although I installed it), second bearing (rear/left) went 40,000 miles, and the Sport just turned 92,000 mi/148.000 km while it was eating this bearing alive. I remember some discussion about the meaning of the suffix on bearings, but don't recall the details. The French bearing MG supplied me was 6204-2SG1, and this one: 204-FF. While dimensionally the same, what is the difference?

Pretty amazing, though, to find this trouble yesterday, and have it fixed today. The replacement bearing: Federal Mogul "National Bearings" 204-FF. (what, in the world, does that actually mean??) Heat gun on the race, bearing in the freezer for 15 or 20 minutes, drifted right in.

Out pretty easy with a little heat (gun), resharpening the punch on the bench grinder a couple times and the judicious application of f=ma (500g Gedore machinist's hammer). I can have a bearing tonight and back together again. The question is whether an O'Reilly "name brand" built in China is same/better/worse than the 7year old French bearing* that just failed. Other bearings I've found on the Guzzi are made in Turkey or Poland. *(EDIT 10-17-2014; Just found in my records having replaced this bearing again after 35,000 miles - so: under warranty at ~14,000, another French bearing went 35,000, and again, now, after 40,000.)

Thanks, Hubert! Indeed, the pistons were being pushed back into the calipers by wiggling at the wheel. Here's why:

Right now, it feels solid as rock after sitting overnight. After rolling along a short distance, it goes away again. Never had one do this before. I thought maybe a warped rotor is pushing the pistons back in to the calipers, but I don't feel any pulsing in the lever.
