I'll try to be as detailed as possible here. First the basics.

-1350 miles on the bike
-never tracked
-broken in, first service complete
-zero previous issues or indications
-OAT 82'F
-water temps time of occurrence 184 after 20 minute sit, prior to that low 200's (210-214)

I rode in search of different riding boots today. I've had the bike since January so today's ambient was the highest I've experience so far. 95% of this ride was on the highway. I exited the highway and then rode about 4 miles in <40mph traffic. Water temp increased to about 214. After 20 minutes not finding a solid boot option I left for lunch, rode another 10 minutes on the highway, parked the bike, left the fan on for a minute or so and then went for lunch. Temps about 200 or so at this point.

After a 20 minute sit, I fired up the bike, water temp had cooled to 180'ish. The bike started normally but had an extremely lumpy idle. I though it would stall immediately but it didn't. I managed to get moving about 30 yards and when I pulled in the clutch to stop, the bike stalled. It started again without issue but at low RPM, the fueling was a mess. The idle was off, and the bike seemed like it was going to stall at any moment.

I rode about 1/3 of a mile and pulled into a gas station. While I didn't need fuel, I decided to go ahead and top it off and take a moment to look around. When I removed the fuel cap, it was like opening a can of Coke. Clearly there's an issue with the fuel venting system. I have never experienced this with the bike before but I've also been riding in relatively cool temperatures so perhaps the higher ambient heat is creating some vapor issues. I'm really not sure.

After fueling, the bike was perfect. No issues. Rode 20 miles home and called my dealership who offered to come and pick up the bike tomorrow since I'm leaving town in the evening. I don't expect this to be a big deal but I do think it could be related to the issues some guys are having with starts. I will update this thread when I hear back but I suspect that will be the better part of a week.

Now, before the haters let lose, I'm not very upset about this. Making a hight performance machine that gets 100mpg and makes no sound is quite an undertaking. Euro fueling issues have been problematic for more than one bike manufacturers recently. I'm more than happy to give Ducati and my dealership time to get this right. If the problem persists, then I'll take issue.

Correction to my original post, 1604 miles.

Not sure how many of you had 1098's but their high temp stalling issues were notorious. Hopefully this is an anomaly.

 

[gurneet]

Wow, I feel for you! Now I am starting to get worried about my duc. Hopefully, your bike is okay!

So something similar happened to me , I went riding all day Saturday through the hills up and down freeway doing about 225+ miles without an issue didn't move or start it Sunday then Monday morning I turn it on to go to work as I flipped up the kill switch and hit the ignition button it hesitated to start so I tried again and fired right up got to temp 122° then I left got down the street and jumped on the freeway everything seemed fine and as traffic start to pick up ibstarted to down shift to slow down as soon as a pulled the clutch my bike shuts off , I called the dealer to make appointment ... So as far as I know by asking questions this can cause some issues ( if you fill the tank sitting on bike can cause the charcoal canister to fill and clog ) the could be the issue at hand ....

 

[bucfan444]

Wow. Please keep us updated. I only have 350 break in miles but have yet to experience anything close to this or the hard starts.

 

[Dingo]

YES... if you manage to get fuel into the little hole alongside the fuel fill hole, you will have problems starting the bike. My salesman told me this, however he didn't go into detail about whether the bike would stall at some point.

He also said if you put a smoke windscreen on the bike to cover the LCD panel with a rag when the sun's out, otherwise the optics will fry the screen - he's seen it happen he said :surprise:

Was it a vacuum or pressure being released when you opened the cap? It sounds like it cleared up after venting the tank to atmosphere, does sound like it may be a venting issue, keep us posted.


My only issue thus far is a persistent surging at 4000-5000 rpm when engine is hot. Have not tried Sport mode, always been in Race, this could be the touchy throttle everyone alludes to in Race mode. If so, it's much more than just a touchy throttle as the bike bucks and surges pretty bad sometimes.

Suction, not over pressure is what happened. It makes sense that suction would cause fueling issues. As soon as the tank was vented the bike ran perfectly. They will be picking my bike up in an hour. I'm out of town this weekend but I'll post as soon as I have anything for the group to digest.

I haven't experienced any surging but I only ride at WOT so......

 

[Kruz]

Yea, if it's pulling a vacuum on the tank, it's reducing the head pressure to the fuel pump and possibly going lean. I need to check this the next time mine starts the surging, it seems to happen only after I've run the engine for about a half hour. I 'll vent the tank and see if it makes any difference next time. Mine doesn't surge at WOT, only at partial throttle in the rpm range specified.


Thanks!

I wonder if changing to an aftermarket fuel cap would help? This sounds like it may be becoming a common issue.

 

[Kruz]

Don't know, I'm leaving in about 20 minutes for a ride and it's getting warm outside, mid 80s here today, so it should be interesting to see if I have issues with exhaust heat and the surging. If it starts, I 'll pull over and release the cap pressure. This may be one of those Euro 4 compliance things Ducati needs to work on.

 

[Kruz]

Well that ride went pretty well. It's about 82 F here and although I did feel some heat on my left under thigh, not too bad. Stopping in traffic, I'm able to get my leg away from the bike and it cools right down. The heat is always there but I think you'll stop noticing it after awhile.


I'm happy to report there was no suction or pressure release from my tank when I made a petrol stop and the surging issue seems to have subsided , for the most part she behaved very well today. I'm guessing it was a load of water or stale fuel from a previous fill up.


Starting hot or cold is still one or two revolutions and it comes to life.


I'm starting to like this bike, it's a gradual thing but it's creeping up on me a little at a time. The quick shifter is butter smooth and the bike loves to flop over on it's side at the nearest hint of a corner.


Another cool thing about this bike, it never feels like it's going fast even when you're really hauling, hit 110 mph again and it felt like I was just out on a stroll.

I've had two stalling issues at idle after riding for awhile, didn't notice any relationship to refueling. I wonder if the charcoal emissions canister has anything to do with it? It has caused issues on other bikes, especially if the tanks were overfilled and they got fuel in them. Extra plumbing is never a good thing.

Checked mine today when refueling, no suction. Get yours checked out by your dealer if this continues.

 

[levigarrett]

Heard from the dealership today. They want to remove the charcoal canister for starters. I generally do that myself immediately upon getting home. We'll see how that works.

 

[tko]

Remove it as in leave it off, or as a troubleshooting step?

Remove forever. Tbh, I've always taken them off and thrown them away. Everyone I rode with in FL had the canister removed. It's common.

 

[tko]

Right. I was just surprised that the dealer was going to do that. Hopefully thats the issue for you.
