New V7 Special 850 Stumbling

<< < (8/9) > >>

Vagrant:
My 2020 V85 has a stumble / flat spot at about 3500 rpm and again at 4200-4400. I suspect it's a "pass emissions " thing.

I would have to crash one of my Guzzi’s to get another.
I seriously cannot conceive of buying another new bike in my lifetime..
Unless I ride a V100 in Mandello this September

GuizDiag does not work on the V7 850 as the 850 uses Can Bus for comms rather than the K line of the older Guzzis.

New to MG coming from an old BMW airhead. Many of the comments here mirror what I'm seeing in my 21 V7. Over the past month, have noticed a long crank before start (not always- when it happens it's almost always first start after sitting overnight), and during the first 5-10 minutes of riding an occasional stumble, like a momentary loss of power. The latter almost always is associated with steady throttle or when initially coming off throttle. It seems to improve/go away with time/miles.

What is weird about this is it started up after I mounted a center stand. To do this I loosened the header flange and muffler mounts to gain clearance. So, I thought maybe I did not have the headers well seating and perhaps O2 was getting introduced in the exhaust stream and messing up the sensor. I remounted to see if that helped but it did not go away. I guess another coincidence is I'm riding more and the weather is notable warmer. I live in WI, got the bike in November, so really this is the first riding where the temp is above 30-40F.

Anyway, have my 1K service soon and will mention to MG and see if there is anything they can offer.

Great site here!

I purchased V7 850 last November. It stumbled at any steady speed under4,000 rpm. I took it to dealer and after several technicians told me there was nothing wrong. The service manager finally rode the bike and admitted it had a bad problem. He asked that they keep it to figure it out. After a week , I was again told it drove exactly like other 2021’s on the floor and there a was nothing wrong. When I went to pick it up, the owner rode my bike and another one off the floor and stated it was worse than a stumble. This was early last March.

The service manager contacted Moto Guzzi and the Guzzi representative stated there were several complaints like mine and they are working on a new map. Yesterday, the new map was installed and now the bike runs perfect. Not even a flutter!

Now a very happy V7 owner.
