  1. For a production air cooled push rod V twin a Guzzi big block makes good power. The newer 8V CARC engines make better power, but they seem to less fuel efficient. The older 4V engines like from the Daytona and Centuaro have their own issues but they make good power. All three are big block Guzzi's, but each of the three has a different character. Being oversquare is only one aspect of engine design. If you make an engine oversquare but you don't have the flow past the valves to support the oversquare aspect you could make less power, not more. Being oversquare alone does not make more pow
  2. I don't think HD is chasing HP. They are after torque, it seems. And feel. HD has built some pretty powerful engines. Obviously there was the V Rod engine. But they also built a 1200 air cooled engine for the Buell that made 101 HP (mine put out about 80 HP at the rear tire, more than the wife's V11, and over 70 ft/lbs of torque). That was a seriously sweet motor. Not like a V11 motor, it was much more of a stump puller that would still rev while the V11 motor is more of a mid-range motor. Certainly HD could build a more modern engine, but really they seem to be doing fine where they are.
  3. We did install a power commander on the wife's V11 years ago. That was before options like Guzzi Diag came out. The power commander on the wife's V11 works well. but it is old school tech. The newer Guzzi Diag options has potential that the power commander could never have. That said, it should run fine stock, and if yours doesn't I would do as docc suggests and perform a basic tune up. You never know what state a used bike is in when you acquire it. Once the basics are good there is plenty of time to go down the Guzzi Diag rabbit hole.
  4. As mentioned, the key to the fuel sensor is it has enough resistance when covered in fuel (kept cool) to prevent the low fuel light from lighting. As long as there is enough resistance, it really doesn't matter how much there is. When it is exposed, uncovered, its resistance goes down and it can flow enough electricity to light the low fuel light. It is a really simple circuit. Besides testing the resistance of the sensor you can confirm that applying 12 volts to the rest of the circuit will light the low fuel light.
  5. Not only do you not need to flush the old oil out, if you find you are out in the middle of nowhere and need to add a quart of oil and all you can find is dino, you can add a quart of dino oil to your sump of synthetic oil as needed. The two types of oil are fully compatible. In the early days, they sometimes didn't mix well. But those days are gone.
  6. It sounds like the OP is talking about the side to side play in the floating brake discs. That is normal, and as long as there is no rotational play in the buttons that locate the brake discs he should be fine. Full floating brake discs have side to side play. And they also can make odd noised when wheeling the bike around in the garage or driveway. But as long as they have no rotational play between the disc and the carrier you should be fine. I prefer pads that are of a softer material than the discs, so it is the pads that wear. But there are some interesting pad materials out the
  7. First, you have to think about how the horsepower is being measured. If you are measuring it at the rear wheel, there is likely around 15% more power at the crank. So a bike with 100 hp at the rear wheel has probably around 115 hp at the crank. Then you have the old joke about how small Italian horses are.... As a former racer of Ducati's, I know all about inflated horsepower claims. Our Ducati racebikes would make an honest 75 hp at the rear wheel (two valve air cooled 750 twin). We raced against guys with similar motors claiming upwards of 100 hp at the rear wheel from their two valve 7
  8. Unlike newer Guzzi's like the V11, the airbox on the Daytona was not exactly ideal. So a common aftermarket mod on normal Daytonas was those velocity stacks and foam pod air filters. Mine (not a Dr John) had them when I bought it. They have since been swapped out for better quality pod filters. I have considered trying to fit a V11 airbox to go with my V11 subframe, but I would have to fit the V11 gas tank as well and don't see that as likely. I prefer the Daytona gas tank. But with the V11 subframe on mine the stock airbox for a Daytona isn't an option. So, pods it is. Not ideal, but it
  9. Welcome to the forum. Do you own a Guzzi? If so, which one?
  10. We replaced the original battery in the wifes V11 with an Odyssey PC545. Ran it that way for years, but swapped it out before leaving on a long trip years back. The battery wasn't dead or anything, just didn't want it to die on the trip (had a bad experience with the original). After sitting in my garage for a few years, the battery in my lawn tractor died. So I grabbed the PC545 and put it in the lawn tractor, where it is still chugging away now. It just keeps going. And it gets very little special care or attention, nothing what some do for their batteries (docc?). I mention it because
  11. And that would be a widget in my world.
  12. How do you connect to the ECU without a widget?
  13. Yes. He is. With a widget and some software you can write new maps to the ecu.
  14. Many years ago we had Penske build us a shock for the wife's V11. I can't remember if we gave them her shock or simply gave them the measurements along with weight and riding style. What I do remember is we were tight for time and they came through for us and we had the new shock in time for our motorcycle trip. The original Sachs shock had done what they do, the lower eye had cracked. And as such the shop doing the new clutch would not put it back together with a broken shock. So we needed a shock quick, and Michael Himmelsbach at Penske came through for us. It has been a great shock as well,
  15. Yeah, and while I value Phil's knowledge and expertise, Pete has such a way with words when he is telling you things you need to know. "CF on a Guzzi is like shaving an elephant to make it lighter!" Classic. (sorry, this post is wandering off topic)
