There is more to get out of hot rodding a V11 motor then there is out of a typical Japanese motor because they are not even close to the limits output wise for what they are. They have a lot in common with Harleys in that respect. No, you're not likely to make a V11 competative HP wise with a 1000cc four banger, or even a Ducati 1098. But you can add roughly 20-25% without too much effort and little cost to reliability. Try getting that kind of improvement out of a 1098 ($$$$$$). Hell, just normal breathing and fuel optimizing can net you 10-15%. Dyno readings vary, so it's hard to compare readings from different dynos and/or operators but my wifes V11 went from about 70 at the rear wheel to 75 with pipes and a PC. K&N filter in the stock box along with porting and adjusting the fueling to match has brought it up to 85 at the rear wheel. I don't think the fueling is perfect yet and could see hitting 90 with a bit of time and a few small changes, but for the time being she's happy with it like it is. And there has been zero loss of ridability and reliability.

It's settled, then. Send the ohlins to me, and send the shipping bill to Guzzimoto.
Doh!!!!
-
Yes.
Edit: You can use other combustable products, not just propane.
-
I'll pay shipping!!!

I agree that plugging is riskier closer to the edge of the tire and that I would not want to do it but probably would in a pinch.
On the Slime issue, I have used Slime and not had an issue, but my tire guys hate that foam flat repair stuff and say to avoid it if you can and if I use it, be sure to let them know ahead of time.

I'd not touch the relais - they're good enough (new in your case), I'd not open the oil-temp-sensor thread - even the title is bullshit, and I'd not make things even worse than they actually are - by just jumping from one into the next thread and applying all you'll find to your poor lady. Look, I have 100.000 km on my Sport and still the Siemens relais built in. Because they do a good and reliable job. Others have tried out every relais they could find on the market and only one make seems to be good enough for them. That's a great story. Hey, you thread necromancers, why not let the oil-temp-sensor rest a bit and disgrace the good old relais thread a bit instead
If you don't have the knowledge to DIY maintain your V11 then you better go and see an average mechanic who is keen on working on a bike, he'll fix it for you and maybe he'll also show you how things work. Try the next Japan shop, for instance. At least over here nearly all of those guys have 1A equipement, 1A training on the job, and a good motivation to get one of those famous bikes under their fingers. For a trained and experienced mechanic it makes not much difference whether he works on a lorry or on a bike. They know how to measure sensors or how to synchronise carbs/flaps or how to track down a shortage. And he'll tell you when something is to complicated for him (getting parts or special tools e.g.)
Guess how many trained mechanics are writing in internet forums, or, same question, how many professionals are playing in amateur bands?

I'm glad your Siemens relays are still going. On my wifes bike, one week after we bought it, the bike stopped running leaving her stranded. A friend of mine, who works for Siemens, picked her and the bike up in his truck. They popped the seat to check out the battery. He saw the Siemens relays and said "there's your problem right there". The bike went to the dealer, who new what was wrong before the bike even got there based on the symptoms. Swapped out the relays and the bike fired right up. We have learned to carry spare relays with us whenever we travel.
I agree the bikes are simple, but you do a better job of setting it up if you are used to Guzzis and have the right tools (software as well as hardware). Take what you can get but I would rather a good Guzzi mechanic worked on mine then a good mechanic, and I would go to a Harley mechanic before a Japanese brand mechanic.
You may want to figure out what knob you turned, but if you put it back about where it was the bike should run acceptably. You may have another issue going on.
-
I feel your pain. My local dealer NEVER mentioned the trans recall for my wifes V11. I found out about it from this board.
Then when I asked him if my wifes bike was in the recall range, he said he would look into it. When he finally got back to me he said "the parts would be in in a couple weeks". I'm thinking I wasn't sure I wanted to have you guys do the work. But I wasn't going to leave them hanging, so they did the work. The bike was back in the shop (a different shop) a month after they did the work to have an oil leak fixed......

There is a fuel pressure regulator that would prevent over-pressurization of the fuel system. But a TPS out of wack or throttle bodies out of sync or even a fuel pump that runs when it shouldn't and not when it should all could cause the symptoms you describe.
-
They have officially issued a recall and your dealer should be able to access info on it easily.
I will see what I can dig up.
-
Ask away. It was not the first time someone has asked that. There are a number of things in the manual that either were not translated well or mis-printed. If in doubt, ask.
-
If you remember where the screw was set, put it back. No, this is not perfect but should suffice to make it run. It sounds like you have a seperate issue going on with something, probably the fuel pump, running with the key off. A sticking relay might be causing this. If you have not already done so you may want to replace the 5 relays under the seat with higher quality units. Adjusting the idle on these bikes is not as simple as it is on old carb equiped bikes. I believe there is a way to set the idle mixture but you may need special tools. I have a Power Commander and use that.
You may want to sync the T.B's and set the TPS now.

First off, Pete it is great to hear from you again. It has been too long.
Second, I think if you want to build ANY bike into something more then what it is then more power to you. But if you post what you want to do with out thinking it thru and ignore the realities of what you are doing, don't be surprised (much less angry) when someone with more knowledge then you post opinions that don't agree with your plans.
Lastly, I don't think there is as much room for improvement in the new 8V motor as there was in the old motor. In order to get your 125-130 hp (if it can make it) you may have to give up a lot of streetability. You can probably make the most improvement with getting the fueling right, but that is hard to do until the PCV comes out. Other improvements are going to be harder to get, Most will either be small and/or come at the expense of streetability. This is not to say it can't be done or that you shouldn't do it. It is just that it is more like trying to get big improvements out of a 1098 Ducati then an air-cooled two valve Ducati. The less refined a motor is the easier it is to improve upon. The 8V Guzzi motor is much closer to the edge of what it can do then the previous 4V motors.

Don't be bustin' on Naty Boh, Hon.
It's a B'more thing.

By the way, most (if not all) octane booster is a waste of money and does not deliver what they imply it does.
-
That is a European rating and does not directly equate to 'murican. I assume you are in the US. We use RON+MON/2. It is fine to run US high test in your Guzzi. Some bikes do suffer from light knocking in some situations but that is easily fixed with a PowerCommander, or you can go the Ratchet route and fudge the engine temp sensor reading (see engine temp sensor thread).
-
Sorry,I was refering to the compression on one side, rebound on the other. The guts of the fork. Whether it's right side up or upside down is another matter.
-
That's funny. Not suprising, but funny. The Guzzi specs are wrong again. Looks like the forks are just modern versions of V 11 forks.
-
Sorry but you have it wrong. If you've ever measured one, the readings are steady and repeatable in the tight range and vary substantially when you get into the range out side of calibration.
Edit: A sensor is more accurate if 10 degrees is represented by only 50 ohms rather than 500. Remember, the ECU is reading voltage after the sensor. Small ohm changes mean small voltage changes or accuracy. What you are suggesting is the engineers are having these sensors be in their most accurate range at -40C rather than in normal operating operating temperatures. Why?
That is not how the thermistors I work with work. You may be confusing the range the thermistor is most accurate in with the range the thermistor is least sensitive in. They are not one and the same. Yes, it may be easier for you to read a value when the reading slows down, but that does not mean the computer is in the same boat. The range a thermistor is most accurate (which is what I assume you meant when you said "sensitive") is determined by the material it is made from and it is usually somewhere in the middle of it's range, not on the far end of it's range. The air temp sensors I work with are usually most accurate in the 77 degree F area, where 5 degrees is worth about 1,000 ohms.

Preload is adjusted on both sides at the same time normally. And you can't miss preload adjusters, they usually stick out the top of the fork leg. I do not have either (V 11 & Griso) but don't recall seeing preload adjusters on Brevas or sports, but the Guzzi spec sheet says there are (but no reference to compression or rebound).
-
No, that's backwards. The larger the difference in resistence between two temps, the greater the precision in the reading.
The less difference in resistence between two temps the harder it is to tell the diference.
Picture a tach. What would allow to read the tach more accurately, more or less space between the numbers?
-
Preload (which I don't think it has) would be on both sides. You probably mean compression and rebound. Don't know which side is which.
-
I tried, at the suggestion of my local dealer, a BikeMaster brand battery. It looked like a Yuasa, but was a lot less expensive. Not only did it not last long enough, but it failed suddenly and as we were leaving for our bike trip out to Indy for MotoGP. I had to get a replacement battery to fit at the last minute. I'll never try that again.

Generally speaking, I find it a good idea to have a full grasp of wot it is I'm responding to on any Forum.
But as always, that's just me. . .
Dang, that's funny. I nearly pissed my pants when I read that.
Thanks, RH. I needed a good laugh.

Just curious, but how do you live with something you don't survive?? :D
With humor.
But seriously, if we don't survive but we spent the money/made the effort, does it matter? I personally would rather die trying then die fat. Remember, it's not whether you win or lose, well, yeah it is. I think the arguement that we may not survive even if we spend the money/make the effort is nuts.
