threads getting long and I'm too lazy to reread but have you pulled and cleaned the cam position sensor. at that point you should check it with the multi meter. Sweede here had issues with them I know and found dirt cheap replacement ones.

I have read this thread, seen all the suggestions and would have thought that at least one of them would solve the problem.

I confess I have no idea but will be very interested to see just what is causing the problem when it finally sees the light of day.

The O2 sensor doesn't start working until it's up to temp after running for a bit. But even then it shouldn't make THAT big a difference in mapping. It's a corrective factor.

 Smithswede's problem was different . His initial problem was a bad plug cap that killed the ignition on one cylinder , then later he began having problems with cam sensors , but when they fail both cylinders die . Somehow the problem has magically fixed its self .

If I remember correctly, Pete Roper said the magic figure was 60 degC.  Mine flipped dead on when he put his magic machine on it.

Yesterday I walked away from this thing for a while and went for a ride on my BMW, and ended up stopping into a real nice motorcycle shop that mostly messes with Harleys, but also happens to have an Italian guy there who is a Ducati and Moto Guzzi specialist. I'll be calling them on Monday to speak with this guy and see what ideas he has. His hourly rate is more that fair, so I may well just drop the bike off to him and say "fix it".
As I've been reminded, my time may be better spent on other things, lol.
I have a 3 year old son and 4 other motorcycles that run at my house, all begging for attention.

Plan is to drop the bike off to an Italian bike specialist on Wednesday.
I will update once he figures out what is wrong.

Copied and pasted to save time:
So my Italian bike guy confirmed everything I had tested, but found that the ECU is actually telling the right side injector to stay open, rather than me just suspecting it. Bottle trick was kind of messy, so I didn't do a great job of
letting it go long enough to see if the injector would shut back off.
Mike says that the left plug getting a lot of fuel was most likely because the engine was still cold during testing, as I couldn't let it run long enough to warm up for fear of gas-flooding the crankcase. He did confirm that the left side is pulsing correctly, while the right side is staying wide open.
I have sent an E-mail to Todd Eagan at GuzziTech to see if he can repair this ECU, or if I will just have to buy another.
In the meantime, does anyone have an 08-15 V7 or Nevada ECU they'd be willing to part with?
I'm pretty confident that another ecu would solve the issue at this point.

If somehow the map got corrupted causing your problem. Maybe someone here can send you a stock map or an updated one that would make it run batter than a stock one and all you will have to do it load it. All you would need are the cables, Guzzidiag and the upload/download software, and a computer close enough to the bike for the cables to reach.

Just a thought,

That's definitely worth a shot, and I have cables on the way.
I wonder if my old derelict laptop can support the software, but if not, I can always borrow a laptop from a friend.
I may order a known-good ECU from ebay, and map that instead. The bike is for my wife, so I will let her decide,
as she is also the one who worries about money in our household.

Give this a quick read for the basics, a longer read if you want. Guzzidiag runs on win XP and up, maybe earlier versions?

Thanks, Tom.
I believe it will work with my old laptop, which I believe is running Windows Vista? I haven't booted it up in a number of years.
I've had computers at my disposal at work for the last several years, so I haven't had a need for one at home lately.

I ended up ordering a used ECU from Ebay, hopefully it will work.
I did also call the local Guzzi Dealer, however, and their news was that the ECU for this bike has been discontinued, and is no longer available new.
This is a little disturbing, Knowing that I'm probably not alone in hoping that these bikes last a long time like their predecessors.
I have a 1981 smallblock 500 in the garage with well over 200k miles (according to the owner).
I'd love to think that this v7 will still be doing the thing in another 30 years, but I'd be willing to bet I'll end up having to adapt the EFi from a similar displacement Ducati, or maybe a suzuki SV650,
or may even put carbs on, and even then I'll need to figure out spark management. At what point will it no longer be worth messing with?

The V7C uses the 15RC ECU, as does the 750 Breva & injected Nevada's. There seems to be a reasonable supply around secondhand, though the price is variable. This ECU is pretty robust, and according to those who would know, well written. Beetle's map for these is free, by the way, as he reckons there wasn't much to do to improve it. Either get hold of Beetle's map, or one of the later factory versions.

FWIW, my V7C is moving towards your 200K mile target steadily, with a mere 218,000km - it's not on the clock, that stops working at 199,999.

And thanks for reminding me - before I take the 2011 wreck apart, I'd better store a copy of its map, too. Should you need a copy, it's only a cloud away.

The 15RC is also used on the CalVin IIRR. I'm sure the map is different.

Heyyyyy!
Replacement ECU came a day early!
I slapped that puppy on the bike, and she starts right up and runs great!

Now the only problem is that it wants to idle at 3k rpm, even after about 5 minutes warming up.
Anybody know the easy way to adjust the idle speed on a dual throttle body v7?
I'm sure I can figure it out, but would prefer to know right where to go, lest I get something else out of whack that I should have left alone.

You may have an air leak between the throttle bodies and the heads.

Fan-bloody-tastic. Now to run it in. Keep freeway droning to a minimum in the early days, hunt up some tight twisties & hills, lots of gear changes & running up & down the rev range. Change fluids again in, say, another 500 miles - check the drain plug magnets, likely to be some swarf on all of them at first, gradually reducing each oil change. My 2TB had a distinct loosening at around 9,000 miles & another around 19,000.

You should end up getting 55-60 mpg, once you're used to the bike. If it seems consistently high, try a throttle body balance. Schedule one in anyway, somewhere in the next 20,000 miles. No real rush.

How old are your tyres? Just a thought.

Thanks folks!
Yeah, I figure I'll change the oils again soon, and do a few early changes, maybe 1000 miles apart for the first 5k or so.
The tires are the original ones from 2011, so they'll be getting replaced very soon, most likely with Avon AM26 Roadriders, as I've run them in the past and liked them.
My wife is waiting to take her MSF course again in April, and once she does, this will be her bike.
She hasn't ridden in about 4 years, so I can understand her caution getting back into it.
In the meantime, I'll enjoy getting the first couple thousand break-in miles on it.

I'll be in Kansas in July, on my way to Colorado. I'll be going out there for a week long Moto camping trip on my KLR.
I'll be hauling the big green pig in my pickup to Denver, then parking the truck at my cousin's house, and then heading out to see what I can see. Might end up in Utah and Arizona bit as well before heading back to the truck.
The Guzzis will most likely be riding the bench for that trip.
