smartmoto-electronics.com/eva...
In today's video, I'm diving into a common yet often overlooked issue that can affect your riding experience - overfilling your motorcycle's gas tank. 🏍️⛽ I share my personal experience with my 2023 Ducati Multistrada V4 Pikes Peak and my previous Ducati Multistrada V4S, and how overfilling the gas tank led to some unexpected problems.
We'll explore the ins and outs of the evaporation canister (aka charcoal canister) system in modern motorcycles, focusing on its role in capturing and managing fuel vapors. I'll break down how overfilling the tank can lead to saturation of this canister, and the cascade of issues it can cause, including engine stalling and rough idling, especially at lower RPMs.
🔍 What You'll Learn:
The function and importance of the evaporation canister in your Ducati.
The consequences of saturating the canister by overfilling the fuel tank.
How this common mistake impacted both my Multistrada V4 Pikes Peak and V4S.
Practical tips to avoid overfilling and maintaining optimal bike performance.
Whether you're a seasoned rider or new to the world of Ducatis, this video is packed with essential insights to help you maintain your bike's health and enjoy a smoother ride. So, grab your helmet, and let's get into it!
Remember, a small step in how you fuel your bike can make a big difference in your riding experience. 🛣️🏔️ If you've had similar experiences or have any questions, drop them in the comments below.

Do you over fuel your motorcycle?

[@injector90]

I was like you back in the day fueling my V4S to the top top. I thought modern bikes dont have these overfueling kind of problems any more and since our V4 doesnt shine with range i was increasing range indirectly :P And indeed have stutter and stalling! Will check that and fuel normally; thanks for the advice! Greets from germany!

[@normanchen1]

Yes, everytime😅

[@IronDavid081]

I think you saved my mental health!!! I usually overfuel my Mts v4s and after one year i’m getting crazy to understand why she’s not smooth anymore. Do you know how long it takes to “restore”?

[@tomtraynor5384]

Try Smartmoto Cannister removal kit PVE 082 and done. Fill it however you want. No more "whoosh!" when you remove fuel cap. Same on my Hypermotard eliminated coming to stop stalls.

[@alexanderb522]

Thank you very much for this. This explains why my V4PP would sometimes randomly stall at low rpm. Come to think of it now it seems to happen after I fill up. Thank you again!

[@RemboUSMC]

No problem. I hope it helps.

[@alexanderb522]

@@RemboUSMC thank you again for always producing great content. I have another issue with the V4PP that i hope you can help me with. At constant open throttle at around 5k rpm there is “jerkiness” back and forth with the bike that I can feel usually in 1st-3rd gears. Usually goes away past 5k rpm. Would you have any idea why this is happening? Brought it to the dealer but they dismissed it. Test drove a regular MTS V4S and did not feel this. The PP is completely stock.

[@kurushunwalla]

Good point Rembo. Thanks for letting us know, appreciated. I don’t overfill my bikes or cars. Please keep the great content flowing. Cheers

[@RemboUSMC]

Thanks, will do!

[@RichDunn]

Yes, this is important. I made lots of videos about throttle surging and stalling on Multistrada's and Streetfighters. I wrote to Ducati and spoke to top people in Ducati NA at serious length, both on the phone and in person. All either denied a problem or said they didn't know what caused it and didn't expect the factory to fix it. One of them even said Claudia knows who am, ha! I always suspected the evaporation system and overfilling the filler was causing a vacuum problem. It took me and a few MTS-owning friends to fully test running 2-3 tank-fulls which hadn't been overfilled, to fully flush out the system, before all signs of surging and stalling were totally eradicated. Why Ducati can't explicitly state in the owner manual that overfilling the gas tank will cause evap system purging and subsequently some surging and possible engine stalling may occur until 2-3 tank fulls later, is beyond me. I guess they just don't want to admit that this is a problem when it doesn't appear to affect other manufacturers' models when you over-flll their tanks 🤷‍♂

[@RemboUSMC]

There is a comment above from a BMW rider experiencing the same thing.

[@RichDunn]

@@RemboUSMC GTK. FYI, I've owned 10 BMW motorcycles, and none of them have had surging or stalling. A similar story with my Triumph's. It's only been my Ducati's (the last three) that I've experienced this problem.

[@RemboUSMC]

Understood. Thank you for clarifying that @@RichDunn

[@sethzelenik1605]

Maybe im being difficult but i just dont see this as acceptable. A 30k dollar premium motorcycle shouldn’t have to be fueled a specific way. Surging and stalling is a considerable safety concern. This is 100% a design flaw that should be addressed. The worst thing we can do as a consumer is alter our behavior to compensate for a sub par design and dangerous design. My bike is at the shop now with 700 miles on it and the techs have no idea how to resolve this. If I bypass the canister i void my warranty. Just very disappointing situation to deal with after such a large investment in what is a premium product. This is not a motorcycle manufacturing issue. This is a Ducati issue.

Update. Still in the shop. Just made my first payment and I have only ridden the bike a week. Although I am disappointed in the dealership, I will say that Ducati North America has been excellent about talking to me and keeping me updated on the progress. It’s important that we don’t confuse dealership issues with brand issues. Hopefully they can find a solution.

[@aaberrill]

Have been experiencing the same problem with my 21 V4s Panigale. Great video will apply what you have mentioned! For the Panigale's this is even worse as the fuel tank gets cooked by the engine and the fuel just emits even more vapor (especially if it parked after a long hot ride).

[@RemboUSMC]

Glad it helped. I have less of a problem in the Florida winter and more of an issue in the summer so that makes sense.

[@daverodgers9416]

Great video Rembo! Thank you. I have always filled to the tippy top. No problems. However, I live in a rural area, (Eastern Oregon). Hence no stop and go, well minimal when leaving town, so this may have masked the problem. I appreciate the knowledge and will follow. Also, given I always carry extra fuel for long trips, no need to really top up! Thank you again!

[@RemboUSMC]

Thanks for sharing!

[@THEelduderino]

Haven’t had the issue on my Duc MS V4S but what you’re saying makes sense & I’ll pay attention to not overfill. Have seen canister delete kits for my Husqvarna Norden 901, didn’t understand the “why” someone would want to buy think you’ve nailed it

[@davidneven4093]

Cheers Rembo 👍 Good video.....but......it's a 💩y designed evap canister - have a look at it in diagrams or pull the cover off the tank and observe - fuel easily overwhelms the CF because it's downstream and under the tank filler, whereas on say, KTM 1290GT's, it is way back under the passenger seat. The KTM CF does not cause any issues as it cannot flood but riders remove it to gain more under seat storage space. You have a point, though under filling gets Ducati off the hook it causes the masses to complain bitterly about poor range 🙄. That must hurt sales. I removed my CF a year ago and instantly lost all bad effects - I have always fully filled my tank (leaving an expansion gap - just not the standard 1/4 of a tank gap) so I continue to put 21-21.5 ltrs into that small 22ltr tank (wish I could use the phone pocket for extra fuel capacity 😉). No issues and I get 200+ miles per tank. Another myth is 98 vs 95 octane here in Aus. I use both....whatever is available, and no issue with either. You are right, but Ducati needs to redesign their version of the CA emissions control add on CF and stop just relying on telling people to only ever part fill their tank. BMW must be laughing all the way to the bank with their 25 ltr tanks 😆.... Trust me, the V4 will run well without a CF but I understand you have annual inspections to pass so removal is not an option, and there is no where else to mount the thing to prevent fouling the AFR's unless it's bolted on outside somewhere 😱. Happy N/Y to all 👍

[@RemboUSMC]

Thanks for the informative post David. I appreciate it and I am sure others do too.

[@charlesscharfy6607]

Your overfill tube should carry the fuel out the bottom of the mc. The vap canister does not allow fuel to enter the tube into the canister because the vacuum is not strong enough. But maybe I am incorrect.

[@michaelriley3044]

Ok thanks Just spoken with my dealer and he says Ducati are aware it (wobbling)and coming up with a fix apparently Will keep you posted

[@RemboUSMC]

Please do!

[@DCGULL01]

So glad you didn't remove the carbon cannister, right? I'm, for the very 1st time in my life- not modding to 'race spec' or 'off-road use only' right away. Heck, I'm going to let the bike dictate ANY changes, cuz it started off at such a high level. ('23 Tuono 660 Factory). I haven't even swapped out the rear seat for the artsy seat cowling

[@omarbarboza2780]

Correct grammar Is a failure that we are not able to replicate at the dealer, because it happens for a period of time after overfilling. In the Panigale 1199 and 1299 was common for people to remove the charcoal canister, since it is exposed.

[@RemboUSMC]

Great information. Thank you for shating.

[@warren7780]

I think you just solved a niggling issue? I recently had my 2017 Multi Enduro serviced and a couple of recall things done. Riding home I stopped for fuel, yes filled it up with 98 Octane. All good riding home as there were quite a few hwy miles. Next day rode into city (Easier to park) later got on bike fired up and rode to first lights. As I clutched it, she stalled? OK, quick hit of the starter and off we go to the next lights, clutched again and stalled (this while still rolling). Hmmm restart and give a few revs, don't stop now out of city (amazing yes) and no more problems. A courtesy call to Ducati to explain. What fuel did I use? 98, My other Ducati runs the same 98 too. "Oh there's your problem these bikes are made to run on 95" HUH? OK I have been running on 95 now with no issue but then again haven't filled "all" the way. Going to have a closer look tomorrow.

[@michaelriley3044]

Thanks for the heads up👍 Have you ever had a problem with handle bars wobbling on high speed sweeping bends (100+mph) A few guys on a forum have encountered it like myself and have raised the forks through the yokes about 10mm to cure it Have you come across it in any of your comments?

@@RemboUSMC The evap system is very complex on the V4S, but simple on the V2S. My friend removed his and has had no problems. A dealer won't do this for you, but it's not difficult to do if someone decides to bypass the system themselves.

[@TheKerimtopcuoglu]

My V4RALLY stalls at neutral from time to time, doesn't happen often but so far I have been unable to find any solution to it. I have tried everything (including removal of evap canister, throttle body adjustment , etc) but it still happens. It only stalls at neutral (one time it stalled when the clutch was pulled in at first gear) So I wonder if your solution will resolve the issue as I have already removed the canister. Weird thing is I owned a V4 pikes peak before and never had this issue. At one point I thought of a faulty cylinder activation &deactivation process, or an overall cylinder synchronisation problem. The bike stayed at my local Ducati dealer for a while and they found no fault at all. In conclusion I was unable to find a fix for it. I will still go ahead and try out your recommendation though, thank you.

Bypass the charcoal canister and the bike runs flawlessly regardless of fuel level. Seriously, on a bike that struggles to get 30mpg, we need to be able to stuff that tank full. The evap canister and purge valve can be plugged, vent the tank to atmosphere. All is well.

Your bike probably has the same issue as my 2020 Hypermotard 950. Bought the bike new and at 600 miles I had stalling at low idle and when coming to a stop. The intake was clogged and Ducati replaced the tank and cleaned the throttle bodies. At 1200 miles they cleaned the intake and I received photos of this round. It looked like spray foam all over the inside of the motor. This "foam" would hold the butterflies open causing it to stall. Now at 2000 miles the same thing and Ducati said I'm out of warranty and in order for them to cover the work they would need me to sign an agreement releasing them from any future liability from damage to this bike. It appears that the Plastic Gas Tank is dissolving from fuel maybe ethanol then depositing a foam residue all over the intake, fuel pump, injectors, and fuel lines. You probably have a plastic tank from the same vendor who builds all the tanks for Ducati. Buyer BEWARE. Ask your mechanic to send you pictures of your intake if it happens again.

[@RemboUSMC]

Great information. Thank you for sharing with us. I think this may be helpful to a lot of people.

could this cause fuel to leak out? due to oversaturation?

If you delete the evap canister and connect the tank overfill line with a Y connector to the drain line under your motorcycle, it permanently solves the issue 😊

This video would have been useful months ago, I had that cheap crap removed from the bike. This is an issue with DUCATI. If the gas tank is supposed to hold 5.8 gallons of fuel then I SHOULD BE ABLE TO PUT THAT MUCH IN!!! No such thing as "overfilling" unless the gas is literally pouring out of the tank. If Ducati wants to claim that the customer is "overfilling" something then they need to specify at what point that it. They're trying to shift the blame onto the customer so they don't have to fulfill claims on this cheap crap that they put on a $30k bike. Typical unreliable Ducati crap.

[@RemboUSMC]

It is in the manual. If all of us would have read the manual, we would have known. Mine holds 5.8 gallons without overfilling.

[@Waldo1122]

@@RemboUSMC I always filled my tank up to the very top without it spilling into the upper circle yet my canister still got saturated. This is a manufactuer defect that Ducati needs to address. Ducati says "don't overfill" what does that mean? Where is the line indicating that? Do they mean don't have gas flooding out of your gas tank? This is a non issue with Kawasaki, Suzuki, Yamaha, BMW etc... Looks like it is where Ducati cut corners like they usually do. If 100s of people are having an issue with it then CLEARLY people aren't fueling their machines wrong. Ducati is just pinching pennies so they have money for MOTOGP.
