  1. Yep, that is low fuel on an early Sport (chin-pad, external pump/filter) tank. The right "lobe" holds up to 0.8 US gallons of "fuel." Or is it half (or more) of accumulated detritus, water, and "binary azeotropes?" Draining the fuel from the regulator return hose will only drain the left side "lobe." The right side lobe will have to be siphoned from the filler at the top, or the regulator removed, or the tank removed and turned on its head. Fully draining your tank should be properly shielded from the public eye . . . @czakky knows how I wait for these moments . . .

  2. I think you are on the right track by draining the tank and getting *all* the water out of it. Of course, that may not be it, but.. (settling in to camp chair around the fire) Let me tell you a story. One time a guy asked me what was wrong with his Luscombe. His little 65 horsepower Continental would purr along.. hiccup.. then continue purring. He said he was getting afraid to fly it. I said, "You didn't drain the carb at the annual inspection like you are supposed to, did you?" "Uhh, no." We did that, and he lived happily ever after. Water is funny stuff.

  3. Hey X! Welcome and well done. Really nice bikes. Congrats on your sweet Rosso Corsa! Very cool that SUB has an MGS-01. I’ve never seen one for sale. Alas, It’s one of those collector’s things where if you ride it you depreciate pristine value of the bike. Hell, that bike should be ridden! Cheers!

  5. If you find water, you should change the fuel filter, and clear the screen on the fuel tap inlet. I had brown fuzz through my bike fuel system that may have come from disintegrating filter paper.

  6. ...and that, ladies and gentlemen, is why aircraft maintenance is even more important than motorcycle maintenance.

  7. +1 Took a friends 140 for a spin yrs ago to exercise it, not realizing in my youth that a sump drain located mid tank won’t be the low point when a tail dragger is on the ground (my t-craft didn’t have that issue). Ran perfectly sweet till leveling out at 800’, then my very young son asked why the plane was so quiet... After paying an unscheduled visit to the farm of my in-laws on one of their fallow fields, the water was removed by raising tail, then flew it back. Water trapped in the wrong spot is “undesirable”. Drain water, then add some fuel additive, and done. If that’s the issue here.

  9. Another theory. On an external pump tank. Does the regulator valve not have an exposed spring that corrodes? Would a failing spring not cause reduced pressure and would the head of fuel from a fill up not increase the pressure slightly masking the issue.

  10. What year is the V11? I understand the last ones had tanks with integral pumps. I had similar symptoms with my Nevada ie. Was a split hose causing reduced pressure to the injectors. The escaping fuel leaking back into the tank. The fill up increased the pressure just enough to hide the symptoms for a while, but ran pretty lean bluing the can and eventually failed completely.

  14. Nah, I live right here in the Seattle neighborhood of Ballard. I WISH I could ride to Vancouver (BC) right now though (border closed).

  16. Fuel pumped past the injectors returns to the tank through the pressure regulator. You can drain any water/old gas at the bottom of the tank by disconnecting the hose at the regulator, and collecting the fuel as you turn on and off the ign switch. About half a cup will come out each prime cycle.

  17. No way! How could that happen?

  18. I wonder if it could be caused by water in the gas tank. If you can get a small hose into each "lobe" you can siphon a bit out of each side. Then run the bike towards empty closer to home to see if the problem repeats.

  20. Hello, So I started getting the itch for another air cooled Italian. I came to motorcycles fairly late in life after decades of being a bike freak (the pedal kind). My first motto was a Sporster, which grew a bit boring after a few months. Bike number 2 was a shiny new 2003 Ducati M1000 that turned out to be may first moto love for a number of reasons, but went to a new home in 2010. I have had a handful of bikes since then and still do, but not an Italian so before my time runs out I decided to give in to the desire. I have always been Guzzi curious and even looked at the Lemans when I purchased the Monster but landed on the lighter less $$ machine at the time. Anyway, I hunted down a Rosso Corsa and brought it home. It's a 2003 with 20k miles, good shape but a few items to sort out. I'm looking forward to playing around with it and I am already appreciative of this forum for the tech information. Marco69 - I am just up the road from you and you are welcome to a close look and ride to see what the v11 is like. I also really like the 1100 sport and considered one that popped up at SUB a while back. It's a good place to look for cool bikes. They have a 81 Lemans, Centuro, and MGS-01 at the moment.

  21. I am 51 years old and reside in Redmond, WA - Been fortunate enough to live and work in many countries. I have been involved with motorcycle (and cars for that matter) since the age of reason! More than anything I consider myself a student of motorcycle design and its intricate inner workings (some would say a mechanic). I have built, raced and cared for many motorcycles over the years - some more fun than others and some more memorable than others. My first bike was an 1980 Suzuki A100 built into a 125cc road racer. This was my first rotary valve two stroke engine. My first full on restoration was when I was 16 and it was a 1959 Gilera B300 twin - this is one of the most memorable ones. I few years ago, I decided to parts ways with the corporate world and decided to open a motorcycle shop - after all, I had to do something with the almost 50 motorcycles I had accumulated through the years of frustrating corporate work. I don't have that many anymore, but I still have too many, which makes it extremely ironic that I signed up to the forum with the sole purpose of researching whether to get a 1100 Sport or a V11 Lemans. Here is a list of memorable bikes I have owned throughout the last 30 odd years: 1959 Gilera B300 Bicilindrica 1960 Gilera B300 Extra Bicilindrica 1999 Laverda 750 S Formula 1973 Moto Guzzi Eldorado 1968 Benelli 250 Racer (fully built by me) 2000 Ducati 750SS (half fairing) 1999 MuZ Skorpion 660 1962 Matchless G12 1978 Yamaha XS650 (first full custom hard tail I ever built) 1992 NSR250R SP Suzuki A100 Racer (don't know the year - already a race bike when I bought it) 1975 Suzuki T500 1988 Honda NT650 Hawk (I've owned 4 of them) 1987 Honda VFR750 There are many more, but I want to keep this short and only as an introduction. Anyway, happy to be here and I look forward to meeting some of you... Cheers!
