    I just went out and checked the up and down play of the butterflies. Can feel some play, also noted some fuel? leakage on the springs,under the TB's, could be carb cleaner residue I guess.
    Bike has 42,000 miles on it, driven by an old fart pretty gently. I have kept up with oil changes and other maintenance.
    Are you thinking about replacement of the butterfly bushings?

    Nope, although that wouldn't hurt. It's more complex than that and the reason why I won't expand on it on a forum because if I did Harry Hometune and his mate Barry Blivettmouth would immediately start pissing about with stuff they don't understand and then when it all went to hell in a handbasket it would all be my fault! Sorry, bin there, done that. Not happening again, I don't need the agro. Sorry.

    After being on ADV for many years, I can say it's not quite like any other forums, for the most part, due to people it attracted. Especially this here thread has had nothing but quality folks (and one occasional OCD lunatic without a life - such as myself). When I had issues with my first Stelvio, posting on those other forums got me absolutely nowhere, except for some tough remarks on how I messed everything up and to take my shoes off then while walking backwards to bow religiously, full of respect, three times, once a week. And then my bike will be whole again. I am not trying to advocate opinion changes, after all. But do know there is an inmate someone here in this forum who makes and sells to inmates bushing kits that fix similar issues for airhead and later GS bikes, and that everyone appreciates him doing it, I saw no blaming whatsoever. Maybe there can be a similar solution for our Stelvios ..

    A new or used Africa Twin is looking better and better. Bay of Fleas has several TB assemblies that look similar to mine, going to be an expensive fix I guess.

    Everything that a man's hands did, can be fixed by another man. It's nothing but one life learning experience.

    Only if that is your problem. My butterflies have up and down play also. As do most of them. And a slight side to side at idle. That means nothing as my bike idles perfectly fine with a stock or custom map. Don’t make the problem fit the solution.

    Go back to stock. You can leave the stepper disconnected if you want just make sure that the tb connections are 100% plugged. Would be better with the stepper reconnected as you will have a rough idle on a cold engine without it.

    Check to make sure the connections to the canister are also plugged if not already. Connecting them together is the easiest way.

    Then start the bike and let it warm up to 60C and the probes heat up. You can track the two lambda probe mv on Guzzidiag. If there is an imbalance the probes will try to correct it. You may see one trying to correct more than the other. That will at least tell you which cylinder you have an issue with. Then work the problem. Air, spark, fuel. It will be one of them. My bet is still on spark based on your video but not easy to diagnose without being there. You have the skills to figure it out. Just trust them.

    I promise you this, it will be a simple fix. Some may disagree but up to you to pick a path at this point. Always here to help by PM if needed.

    Well, shipping a pair of TB's wouldn't be that expensive and I haven't asked for any payment so I'd think it worth a try but......

    I was able to replace both Relays with new ones and it fixed the problem. Thank you everyone for your help with the diagnosis. I really like having a wiring diagram to help trace down each electrical system.
    Here are a few pics: This is with the right side front lower fairing removed (requires a 4 mm Allen wrench and an 8 mm wrench to remove).

    The relay on the far left with the red tape is the relay that was bad. I had no Low beam, high beam or charging system. This picture was taken after I removed the relays and then just hooked them back up for the picture (not fully engaged on the terminals). The relay on the far right with the red tape is the one for the High beam and Low beam lights. I have replaced both of the relays with new ones from NAPA (p/n MPE AR201SB $14.49 each) and I saved the good one that I removed for a spare, just in case this happens again. I also bought one for my best buddy UTRider1 for his Stelvio.

    Here is a picture after the new relays have been installed.


    Relay After.jpg


    And here is the voltage display after the fix. I now also have the high and low beam lights.

    Thanks again for everyone's help with this problem. Me and UTrider1 will be going for a ride this weekend in Southern Utah through Zions National park and then down in to Northern Arizona.

    I suspect you will find honda dealers charge a lot more to fix africa twin problems than what an enthusiastic guzzi saint is asking, but it's your choice.

    Bruce? If you're that worried I'll give you $2K right now and get it shipped somewhere like Seattle,(Chilliwack would be better!) and Jude and I will come over in July and ride the piss out of it when I've fixed it. It would save us the exhorbitant cost of a hire car! :D

    Glad it worked out - as I said had same problem with mine and just coasted into my garage before battery died. I didn’t know lights were off and it wasn’t charging, now I have a voltage idiot light to warn me....

    That relay connector needs to be pushed in further onto the relay. Looks like it is not in all the way

    I had problems with the same relay with my '13 Stelvio. The Guzzi dealer tried two "new" relays right off the shelf and they were both bad. I ended up using a Bosch relay and that was the end of the problems.

    Thanks motomoda, I am not worried about the $, it is what it is... unless it isn't! How sure are you about the diagnosis? That is my concern, ship something out to bumfuck Oz, wait 6 months until all the goatbursters are aligned right, get it back, reinstall and..........?

    Since it's a Honda, it will run forever, even if you forget to change the oil. Oh wait, you can do that with a Stelvio too, apparently.
