I just got my v4 base model Streetfighter a week ago, and the last few cold starts it just doesn't start on the first two or three tries. It eventually goes after a few minutes.

I messaged the dealer and they said "these 1200cc engines usually don't start on the first try" which I think is a complete bullshit answer.

Anyone else run into this?

Welcome to the wonderful world of Ducati. :)

I've never owned a fuel injected vehicle that had so many cold start and cold idle problems... FI is SUPPOSED to make this all trivial - but not for Ducati for some reason. My 1200 (and it IS actually a 1200) doesn't like sitting outside overnight if it's too cold (can cause hard starting), it doesn't like cold and humidity AT ALL (will frequently cause hard starting)... it doesn't like lithium batteries (a brand new Shorai lithium WILL NOT start the bike (without a number of start cycles to warm the battery up) if it's less than 55f or so (and the new Duc's don't have any big power draw other than the starter so you HAVE to use the starter to warm them up).

And the cold idle learn cycle really likes to get screwed up after some arbitrary period of time and will cause high idle or stall if you don't reset it occassionally.

Now... all this stuff can be dealt with (except the lithium battery problem... I just went back to lead acid to solve that), but you shouldn't have to learn that "a tiny bit of throttle when it's starting hard will always get it going... as long as you don't give it TOO MUCH throttle and flood it", or "if the idle sounds like it's going off then hold it at 1k or so for 10 seconds and it'll usually settle down".

FI should just work... but... TID.

Having owned all manner of motorcycles, the Ducs are by far the worst starters. The fact that it takes more than 3 cranks to start my fully warmed up bike with a fully charged battery is just wrong but pretty much all Ducatis are that way right out of the crate. Typical description of starting a Ducati is that it cranks for so long you think it's not going to start, then at the last second it does start.

If you replace the battery -> solenoid -> starter cable with a heavier gauge one, it will help considerably, especially with cold starts.

I will say that "a tiny bit of throttle when it's starting" is useful advice. putting your hand on the throttle and just thinking about turning it is about how much it needs but this technique definitely works for me.

I have a HM 1100s that hates cold mornings. It has taken as many as 10 attempts to start it! I never touched the throttle!

Then, one day i gave the throttle the gentlest of turns and boom! Now starts on cold days.

Go figure :D:D:D

I had the Streetfighter 848 before this, and it sucked at starting too. So I get what you all mean when you say "welcome to the world of Ducati".

I tried something different myself, I let it sit for a couple days, and then turned the key on and didn't start it. Let it boot up, and you can hear this pump sound kick in after 5 seconds or so. I started it then and it worked on the first try. It seems like I was starting it before it can get ready to start. So all is good.

That being said, excluding this starting process, it actually starts a lot better than my previous 848. That would take a few cranks before it started. But this picks up pretty quickly.

Thought I'd share this incase someone else was running into the same issue

When starting any Ducati you're supposed to always wait until the fuel pump stops priming and the dash fully goes through its start up sequence before you crank over the engine. Your old 848SF may have started better if you had done that.

Yeah the sf 848 used to start up before all that happened, but this one definitely needs the few seconds before starting.

Yup... forgot to add "let the fuel pump cycle completely before trying to start"... you get to the point where you just do this stuff automatically and don't necessarily think about it. :)

I was wrong, this didn't fix the problem. It's still there. I read somewhere else someone said to try keeping the gas lid open when starting it, that didn't work either.

I'm going to mention it at the first service and see what they say

ironically mine started first time, every time until we went to the east coast and rode for a week. I'm guessing it's something in the self learning cycle of the ecu. I'm at 3500 ft asl and we rode the smokies and that whole area for 5 days on better quality fuel. I'm hoping a good ride up here on NM crap fuel resolves it. It's taking 4-6 tries now, where she'd fire on half a crank before. We used ethanol free fuel out east 90% of the time as well.

I recent picked up the 2020 SF V4S. I had the same issue. If I try to cycle it to start too quickly it will have a hard time starting. If I turn the key to the run position, wait for all fuel systems to gain pressure and then you will hear what sounds like two relays clicking, After that sound, she starts right up. This has been very consistent. Hope this helps,

I've been using good fuel too. The first refill I used petro canada 95, so that may have messed it up. But I've refilled around 8 times since then, and everytime I've used shell 91.

I hope using good fuel and after this long trip things go well. Keep us posted

I've tried this every time. I let it start up for at least 30 seconds, I head a pump, rather than relays clicking, and I try to start it then. It worked one time, but it hasn't since. I have my first service booked for Tuesday, I'm going to me took it to them and I'll report back here.

How long were you waiting to hear the relays click?

It usually takes about 10 - 15 seconds after the fuel pump turns off. Then I would hear two clicks, starts every time after that.

I know which two clicks you're talking about now. Yeah it doesn't start for me unfortunately. I'm in an underground garage 2 floors down, i wonder if that play any role in this. It's a stretch, but I can't think of anything else. I'm at the dealership now doing my first service, and again, they're saying "ducati's are notorious for not starting on the first try". It's bs, but we'll see what happens.

Your underground parking facility should have nothing to do with how quickly your bike starts. Parking garages have ventilation that keeps the air clean and the oxygen levels safe for humans and vehicles. If your parking garage has extremely poor air quality you would be on the floor passed out and your bike would still start in low quality air.

So this is weird, I had a cold start issue yesterday. It acted like it didn't want to start cold . I stood the bike up right and level and it started with no issues. It was in "N" and the kick stand was up. No issues sense then. The bike does act surprisingly different after the first service. I also found that using a battery tender has helped.
