    Loss of power/engine cuts - still there

    So, update of the day! I took the bike for a long ride this morning to have it warm and do the wiggle tests! The first half was amazing. 30 miles of pure happiness in the canyons, no cuts whatsoever, power everywhere, rock stable idle, working fan, etc. Arrived at the top of the mountain, I...

    Loss of power/engine cuts - still there

    Good call njloco! Thanks :) Once I've figure this all out, I'll definitely do a second pass with the right lube on the right screws/bolts to make sure everything is perfect. Now, I just finished with the big engine ground. I cleaned the hell of that thing, and the big chunk of wire is in okay...

    Loss of power/engine cuts - still there

    Yeah, I ended up in the ER (thankfully it wasn’t a big deal at all) one day because of a massive shock. I was working much younger on the kitchen with my dad and as I was wiring the electric stove, for some reason the electric switch was on. Touched half a second the wrong cables - 220v and 32A...

    Loss of power/engine cuts - still there

    Sorry if it looks confusing sometimes, maybe it is in the words I used. I will try to define more specifically one thing that I think can be confusing: "engine cuts": I really translated the same words as I would use in French and maybe it is incorrect. What I mean by that, is that with the...

    Loss of power/engine cuts - still there

    - Noted for the coil - interesting and glad to get the correct information, thanks. I'll leave that aside then. - Very clear for the electrical issue. I am not certain all grounds are pristine, and neither do I know if my ECM unit is good. I haven't tried another unit and I did not perform the...

    Loss of power/engine cuts - still there

    Hi peeps! Here is some update on the long quest to get rid of my engine cuts. - Previous symptoms lead us to believe the intake leak could most likely be the reason for the engine cuts around 4000 rpm (with nice backfires) - The AFV setting was also getting very high (over 120%), which...

    Hmmm...

    OMG this is hilarious! Well done 34:19, this truly is one of my favorite best April 1st joke I've heard so far (right behind the day a good friend tried to make me believe she was pregnant and I was the father. Another dipstick story I guess :eagerness: )

    AFV at 128% & engine cuts

    Hahahaha. It doesn't make any sense. I just went for a ride. Well, please find the log below: https://drive.google.com/file/d/1ubzxJw-81CS7JYC2fytarld8QUScHVjo/view?usp=sharing Almost no issue AT ALL. Went almost to 6k rpm without cuts - except for just one time, at the end of the trip and...

    AFV at 128% & engine cuts

    Oh god. I am in love with this software, pure eyegasm! I just tried to get the software - not sure the difference between the MS and the HD though. Which one are you using? It is so useful, I would have never been able to identify by myself this rev hang you were talking about! Incredible...

    AFV at 128% & engine cuts

    Oh yeah, sorry I only put the log, with the two files created by ECMDroid. You can find my EEPROM file right there: https://drive.google.com/file/d/1WvCrPZNJ2JZBG3eEZ8NKpwH7yhXBwSar/view?usp=sharing Please note the only change I ever did on it was to burn the new AFV value to 100.

    AFV at 128% & engine cuts

    Ok! I’ve already ordered the new intake flange and rings from Twin Motorcycles. After 25 000 miles, I guess it’s expected. Before the tps, it was sometimes idling a bit low I realize now - and in that regard it runs better now. But apart from the first start after the AFV set to 100 which...

    AFV at 128% & engine cuts

    1) The first time I tried to reach over 4k rpm, it was so loud and it felt clearly closer to my face - I would say it was on the intake side, not the exhaust (but that's really based on a perception). Plus, the exhaust's after fire definitely are numerous, not so loud and don't happen during...

    AFV at 128% & engine cuts

    lowkey, I just went through all this - although I just see the EDIT you made haha... Well if anything I'll just update the procedure later with this extra step! Here is the detail of all requested information / actions 1) My TPS degree before the reset was showing 3.7 2) I did not activate...

    AFV at 128% & engine cuts

    lowkey, thank you for taking the time to prepare such a comprehensive reply! I will work on this probably over the weekend. In the meantime, here is the information you requested: - 2005 Buell XB12Scg (the chassis says 2004, but I guess the Scg only started officially on the market in 2005) -...

    AFV at 128% & engine cuts

    Alrighty, test done tonight after a quick 10-minute ride in the neighborhood and few dogs scared by the decel popping. I did the test only from the right side (as described in the Manual). It's not an easy diagnostic. The manual mentions a "change of tone" and the video from Twin said it could...

    AFV at 128% & engine cuts

    Alright, good to exclude the ECM, I can focus on the potential intake leak. As for the spray, does it have to be necessary brake cleaner? I'm just curious about what's in it that creates the RPM to drop. EDIT: to try to clarify my mind - so far I believed that inflammable liquids would higher...

    XB9s Fuel pump

    Will do! I just need to figure out the Cooter "A-frame ladder" system to lift the rear - a picture maybe?

    Haha same, my tank is full! I just ordered the part tho, better safe than sorry.

    AFV at 128% & engine cuts

    Hi peeps! After a ride today, it turns out my XB12 still needs some work. A bit of context here. The situation - When I bought it (less than a hundred miles ago), the engine won't feel so great and going over 4000 rpm would result in engine cuts, plus I'd hear a lot of after fire in the...

    XB9s Fuel pump

    Haha! Yes, I saw this one! I even tried earlier but it didn't change the situation - that's why I was wondering if the fuel pump could be related. The battery is brand new (+ I have a tender that I plug once a week, but it's always showing 100% charged so far) and it's really not slow cranking...
