I caught the issue the first day with owning my 2020 ATAS

Welcome to the Forum. It is worth to you have a Cup of coffee and seat to read this 600 post tread.
You will be more than informed on the Issue.
And Yes, I will take a normal AT. No Problem.

Doing a little more digging around for solutions, what are the forum members thoughts on using a few ml of acetone every other fill up?

I just got preapproved to buy a 2020 ATAS, but I see this thread and am a bit hesitant to pull the trigger now. Hear that Honda?
I did just watch a video on how to pull the tank and it's not that terrible, but why should I have to do this to my brand new bike?
Is there any reasonable expectation that a dealer who just wants to sell bikes will have their service department do this for me (for free or as part of setup) if I agree to purchase it?

You could always try, but it wouldn't surprise me if they give you the "that's the first we have ever heard of it" or "it only affected the 2018/19 models, 2020 is different lines."

You could also try calling Honda and let them know you are pre-approved, but after reading through 600+ posts about the issue you are not comfortable with the purchase unless they agree to remove the tank and scrub it as part of the PDI.

You'd get your money's worth out of the PDI fee.

This might be the link

Right? Such a bloated fee and then some dealers still don't do it right. Not replacing the brake caliper bolts, mounting the wheel incorrectly, etc.

That maybe the link, but this video is about a '16 CRF1000 AT (not Adventure Sport), rather have a video of a CRF1100 ATAS tankremoval .

I could not find one for the 2020 AT AS ES DCT, which is what I have. Only 425 miles on it and trying to decide how to deal with it. I believe I should go ahead and install the Guglatech Mazinga pre-fuel Filter. This way I could possible prevent the stall issue before it starts.

Hello all and thanks for the informative posts that will help convince folks to be preventative with this issue and remain safe. Whether one decides to remediate the issue themself or have the dealer do it, as with most things, going into it with all the background information like this is invaluable.

Long story short, I'm in the middle of doing the work myself. The dealer is scheduled to do the warranty work also, and through me working with Honda USA and the dealer, they're on the same page with what needs to be done (i.e. scrub a dub dub, rinse, scrub a dub dub, rinse and repeat, then replace the fuel pump instead of just replacing it with another tank that will have the same issue). However, that fancy fuel pump is on somewhere between a 2-3 month backorder and they won't touch it until they have the parts. Sorta makes you wonder how the Honda production line can be pumping bikes off for new sales if there's such a shortage of fuel pumps!

So again, I'll do the bulk of the work myself, cleaning instead of replacing the fuel pump, and then they can do it all again when they get the pump. At least I can then right from now until whenever that is that they get it. On the bright side, I'm learning a lot about working on this bike, including fairing removal (which wasn't necessary by the way lol), tank removal (ahhh...good to know that for air filter changes and valve checks), plus I like wrenching so that's the silver lining.

I'd post a bunch of photos, but at this point, we all know the issue, the cause, and most of what are the proper steps to resolve it. The one thing I could use some clarification on is this white'ish filter/strainer that many have posted pictures of (pic below).

As you can see, mine has some sort of black media inside it that I assumed was a sort of charcoal type filter. When trying to clean it, I'm getting black residue coming from it but others I've seen posted look completely clean/white.

Any advice? Should I keep cleaning it with gas until it's completely white/yellowish or am I removing function from the filtering?

IP, you are much further along than I am. I’m going to go out on a limb here. Be careful cleaning with the gasoline. The vapors are so flammable you could have a disaster. If you can backflush the Filter with kerosine, opposite it’s path of normal flow, you should be able to clean out the “goo” and remove the “white flakes”, but as I said I’m going out on a limb since I have not executed the cleaning myself. I believe Honda has used a charcoal type of media for this strainer element. I don’t think it will be any other color than grey-blackish. Rinse it out with plenty of water when you think you are done then let it dry thoroughly in the sun. Don’t destroy it trying to get it clean. I believe that element is on backorder too. I have not looked for it yet. The Guglatech Mazinga Filter comes with a new primary element, which I refer to as a strainer that you are attempting to clean, therefore I haven’t tried to find the element by itself. I’m assuming the new fuel pump includes that filter. Most directly, I am hoping one of these other knowledgeable users gets on here to help you with the cleaning process. I’m sitting at home with stitches running down my stomach from a double hernia repair, and have yet to tear into my new ATAS. Please keep us posted on your success.

Welcome to the Forum @IdealPragmatist, and good to read that you are proactively engaged with Honda/Honda Service. This is the least I would expect from a relationship with an authorized Honda representative.

Hi all, a lot of great information on here which is appreciated. I am in the process of finding a 2018-2018 ATAS. If I find a used one without warranty this tank issue will not be covered by Honda and would be up to me to get it fixed, correct? Not sure if I wanted to take this risk even absolutely live this bike. Is there any info on how often this happens? Thank you.

Correct. Unless there is an official recall, an out of warranty bike would not be covered. This is one of the primary reasons many of us are pushing for an official recall. Then the issue would have to be remedied regardless of warranty status.

One option would be to look for a used one that has the Honda Extended Warranty on it. This is transferrable and would give you the piece of mind. Resale peace of mind to a future buyer is perhaps the main reason I purchased it on mine.

Another option is to find a used one where the work has already been performed. In this case the work follows the VIN regardless of owner and if it fails again, it would likewise be covered.

Edit: I would not just take the owner's word that it was done. A responsible owner should save those work orders and be able to provide them to you as part of the sale.

Thank you so much for your detailed reply. Very helpful. Might look at the standard AT then as well. It seems only an issue on the ATAS.

Also correct. The issue is strictly with the larger ATAS tank. You will not experience the issue with the Standard AT. Enjoy!

Thanks, @TN-Rider , yeah definitely have to be careful with gas, I was in a very well ventilated area and in a bit of a push to get it all back together while I remembered how it came apart so I went the gas that I had. It's all back together again, gas station for a full tank and running smooth.

Again, I won't post a bunch of pics that are just repeats of what everyone else has already posted but I will share a few before/afters along with what I found worked for removing it. There are so many areas of this tank you just can't reach. Luckily, my hand was just small enough to get in through the pump opening so I could reach a bit of it. For the rest, I found that pouring a bit of gas in it, moving the take to settle the gas in the affected area, then inserting an air hose with a blow gun attachment and agitating the hell out of the gas in that area worked pretty well. Close the tank cap and shove a rag in the hole for the fuel level sensor, insert air hose through the fuel pump opening and let it rip. Again, better be in a very well ventilated area

Looks great @IdealPragmatist. Thanks for posting your work. The compressed air agitation looks like it really did the job. I am curious how many miles are on your ATAS.
