Agreed. The small amount of AL there is probably well within the tolerance from MG for the rotating assembly. But get a proper impact, air, electric, or battery, for next time and get the proper puller. Don't use a screwdriver to try and pry it away from the case.4 points

Nah mate, I bought one for my bike based on your recommendation. I just didn't say thanks. So thanks.4 points

I hate to do it but it's time to move on from my Ballabio. I just can't comfortably ride 2 up on it. It's a sweetheart bike. The biggest issue has been shifting but that was solved with with greasing the shift shaft, adjusting the eccentrics and changing the trans oil. It has Alpina tubeless wheels which were on when I bought it. The speedo died around 10k miles and I replaced it with a GPS model which now shows 2800 miles. Runs beautifully, never had an issue in the 3 years that I have had it. I would like to see it go to a good home. $3500 or best offer.3 points

I'll take the liberty of linking to a video that Paul Minnaert linked to in the german forum. It is a screen-video showing Guzzidiag running on a Breva 750, i.e. a 15RC ECU. Paul wrote that it goes into closed loop at 3:14. I have to say, I can't see the exact moment, but a bit after 3:00 one can see the temperature approaching 60° C, and that the Lambda integrator and Lambda values change. https://www.youtube.com/watch?v=NUOtoYCifN4 As I understand it, from the 15 RC on, that is how the system behaves. 15M and before (without a Lambda sensor), as already mentioned, don't have an open loop/ closed loop function.3 points

I run nothing but 92 octane ethanol-free gas in my '04. With supposed 9.8:1 compression and old-school combustion chambers, high octane is the way to go. My ECU has been re-flashed, probably by Guzzi-Tech, but the label is unreadable. Never any trace of pinging. I would check your timing.3 points

No , I'm good on theory , I was just wondering. W/O2 sensor computer systems on automotive vehicles the engine coolant sensor decides when to go into closed loop and (in theory) the O2 sensor is hot enough to start determining the oxygen content of the exhaust gases. These sensors started out w/one wire , then a second wire was added to have an absolutely good ground for better reading . Then came the four wire system for the addition of a heating element to heat up the sensor for a faster closed loop engagement . All other (early style) w/o any oxygen sensors were "closed / open loop" from beginning to end . I don't care too much for this but it was less complicated to engineer/fabricate . Being in the nascent stages , everything is simpler.3 points

@docc Pecco has no opinion. That being said, only two pilots have won three times the world championship in a row; the first to have accomplished that performance was Valentino Rossi; the second was Marc Marquez... I have no doubt that Bagnaia would most likely be pleased to win a third championship, on a Ducati. The previous guys did it for Japanese brands. I do not know how verbatim are the comments reproduced in my previous post. I can't help but notice that Marc Marquez does not directly refer to the name of Francesco. When he states: "the favorite is the Champion" he may as well speak about himself; after all, he is also considered a Champion, isn't he?2 points

I can say once summer is here, and the motor has its normal running heat in it, both of my LeMans (02 stock/03 exhaust mods) ping slightly under hard accel. Primarily at hard acceleration when speeds are above 60-70 mph. My 2016 Norge also does this during summer heat, and same hard accel, but this ECU has been reflashed by GuzziTech. I run alcohol free 93 octane in all my Guzzis to minimize.2 points

For clarity in the matter of ECU type, none of the V11 Sports US models came with 15RC nor O2 sensor. Only Euro models! If your V11 Sport is a US import, it came with a 15M and no Lambda sensor - so unless it was modified by a PO . . . .1 point

Wouldn't GuzziDiag tell you what ECU you have?1 point

I was running stock oem map with Mistral crossover & mufflers & no dbk;the fueling is fine. Doc has already replied that you don't have an 02 sensor,which means that you should have a 15M ECU; I understood that some of the later '04 models had a 15RC,idk To make absolutely certain how your bike is set up;get a good light & eyes & possibly sensitive fingers to check all around the H pipe crossover; if your bike is one of the later models with the 15RC,you should find an O2 sensor mounted on the H pipe crossover. If the H pipe isn't stock or has possibly been plugged look for an O2 sensor that might have been tucked up out of the way someplace in that general area. fwiw1 point

Awright... I don't have an 02 sensor on my Le Mans, do I?1 point

To take into account the "StayInTune" exhaust system; https://staintune.com.au/ I am not able to say what ECU is installed in my Le Mans, since the label has been ripped off.1 point

I think all efi guzzis were open loop until the 15RC ECU bikes,which had the ability to read an O2 sensor. I'll leave the explanation of the fine details of how the systems & maps work to someone else,,,, I've read some ECUs & maps use a variety of sensors, # of rpms,etc to make sensor/fuelling changes.1 point

Good looking bike . I'd say BUY IT ! BTW , these people that put a price on it is because they know what it means to them . Don't work on them too much on the price .1 point

I hate to show my ignorance but , do these bikes have an open loop / closed loop built into the computer system w/the O2 sensor style system ? On automobiles the ECM goes into closed loop when the engine is up to operating temp and the O2 sensor is hot enough to start "working". I assume the non-O2 sensor bikes are programmed to run as is throughout the temp (cold to hot) temp range?1 point

I don't know why you remapped your ECU,the oem map fueling on my '03 Lemans is very good,but it is a 15M & I have the trim at +28 (ran well before I changed it) My only guzzi that does have a tendency to ping if I push it outside of it's comfort zone is my '08 CalVin,it also has a 15RC ECU like your '04 Lemans iirc. My CalVin's 02 sensor has been disabled in the map & is running open loop. Lucky Phil's research into high quality Bosch O2 sensors to replace the inferior oems,changes the landscape for 15RC owners;or any guzzi/bike running a closed loop.imho If the faster response times of the Bosch O2 sensors enable the 15RC ECU to make instant changes to correct the AFR & greatly improve fueling issues, that's where I'd be spending time & effort on a 15RC bike,fwiw idk.1 point

I've had a Wilbers on my bike for 10 years. I must have recommended these at least a dozen times here over the years. Ignored I am Ignored1 point

It is an eccentric adjuster pin with a flat blade slot under a dome head lock nut. The way to adjust it correctly is to remove the cover and do it on the bench. Any other way risks the shifting issues you already have. You may need to remove the cover and stop the pin from rotating as you turn the locknut. Get your big boy pants on and dive in and remove the cover. Phil1 point

Good evening from the Moto Grappa at the top of Virginia! Here is the slideshow I made of last weekend’s Moto Grappa Tech Days 2024 [MGTD ’24], the seventh in the MGTD series. I took 800+ pix; yes, really. On the merciful side, while, of course, there are still too many, there are fewer than 1/4 of that original number of this weekend of aging Moto Guzzi enthusiasts (sans spousal units) reliving frat house days of debauchery under the guise of working on their Italian mounts. No dummy and experienced in the squalor that follows in a MGTD’s wake, Kathi, my Perfect Pillion & Polish Princess, flew to Seattle just before the event, and — aside from a cameo to swap the “airport car" for a better one — returned after the follow-on HAZMAT team left. 😄 ========= For those still reading, the link opens in landscape collage, thus allowing you to look at all at once rather than slogging through those individually. Hover your cursor over each pic to see captions. The system truncates some of those in the collage format. The best practice is to run the pix in slideshow form so the pix are larger, tho that can cause captions to disappear unless you keep the cursor in the lower left of each photo. Yes, I know a PITA. Speaking of PITA, the “buy photo” option is nuts. If, for some inexplicable reason, you want any pic, simply download it. If want higher-res, let me know. OK … at last, the link: https://bill-and-kathi.smugmug.com/MGTD-2024/n-cRqfHF Bill P.S. I did not include the following “bonus pic" in the slideshow proper. One of the MGTD attendees left early to rent and ride a motorcycle in Nevada.. He took several pix of his MGTD souvenir cap —à la "Where’s Waldo?” — Here’s one; read the sign!1 point

I don't know if I'm the only one,but I gained about 20 lbs just looking at those pics Not only can you guys eat well,but man,some serious good cooking I never eat local maple syrup because I hate making pancakes;but as mentioned above,your french toast has me armed with one of my cast iron pans & a mission this spring Nice to see the V85TT in it's element;I hope Dave had some type of heated gear to go with those hippo hands,that looked frosty. Tks for sharing1 point

I don't believe "overshifting" has anything to do with the shift linkage docc although always worth looking at of course. More likely the stop adjuster has come loose or it has been fiddled with at some point and has been set on the edge of "overshifting" and as time and wear accumulate it ends up outside the acceptable window of operation. The answer is to remove the side plate and check the whole shift mechanism for faults and while in there replace all the springs and adjust the stop on the bench before it damages the hard to fix internal parts like the gear dogs and/or shifter sleeves.1 point

Just make sure it has not gotten "sloppy." Check the pinch bolt on the shaft of the gear box, the lock nuts indexing the Heim/Rose joints, and wobble at the lever pivot. The lever pivot bolt may benefit from shimming (mine has a couple of times). There is an inboard lock nut that keeps that pivot bolt from turning. Look at the relative angles of the parallelogram and adjust as necessary to get as close to get the gearbox arm and the shift extension arm parallel. The lever has more apparent travel between certain gears, so check that it is not fouling anything above or the Frame Side Plate (below) in each gear change, up and down.1 point

Next, I would adjust and make tight the entire external shift mechanism. Best done with the starter off. Make sure the shift lever does not hit anything on the full up and down strokes in every gear. That is best done with the rear wheel suspended in order to rock the wheel a bit to get it into each gear.1 point

Assuming there is nothing like a Power Commander involved, i.e. the re-map was really just that in the ECU, do you have a copy of the original map? If not, I'm quite sure one could be found in the Guzzidiag "experts community" here in Germany. Or maybe someone here can read out the map on his bike and send it to you. I'd offer to do that, but I don't know for sure that mine is original, and mine is not running all that well anyway. It's got the "cough and splutter at 2,800 r.p.m." syndrom, and I haven't figured out exactly why yet. Anyway... The thought is, read out and save the new map. Re-install the original map, and see how that runs. Put the new one back in, and see if the pinging is worse than with the original map.1 point

It's too late, I've burned up the bike. I'm now a former V11 rider. I took off the starter. Unfortunately, I only unhooked the battery ground. The hot starter wire grounded on the shock adjuster when I was working on it. I smelled fire and got it free but too late. The electrics are dead. Totally. Fuses are ok but there's melted insulation under the side cover. So far as the shifter, I was able to get the adjuster off and backed it with an allen head and tighten it. Have no idea about that. Believe me, I'm sick about it.0 points
