So apparently the tech says that there's nothing wrong with the bike- they are sending it back to me today.

Hoping that it just works... I just bought the thing- don't want issues, just want it to start when I need it to.

Will post up if problem persists... hopefully it just runs and I can move on with enjoying my bike.

Oh great. How can they say that? 5 minutes to start is not acceptable

Seafoam doesn't destroy plastic, rubber, or anything really. It's a petroleum product, has no added cleaners or anything. Gasoline has more cleaning agents in it than seafoam does. All seafoam does is break up the sludge from the byproducts in gasoline, it isn't really a "cleaning" agent.

I dunno where you got the idea it can damage EFI systems, but most bikes nowadays are EFI and I've never heard of seafoam damaging anything in them. The only possible downside of seafoam is if you use it on something with a ton of buildup; you can possibly harm the motor if you have a ton of debris in sludge in your fuel system and suddenly run it all through the motor.

It isn't really necessary to run it through any modern bike because most of them don't have the mileage to require it. However, in my case, I got terrible gas from a station (likely old gas sitting in the bottom that had sludged up) and needed to flush that bullshit out of the fuel system since it was obviously messing up fueling. The V4 only has a 4 gallon tank, so it isn't difficult to run through an entire tank in just a day or so, meaning even if seafoam could damage things, it never sat there long enough to do so.

Cars are EFI as well and seafoam is great, especially used for storing gasoline over winter.

My bike sat for about a week and this time before starting it, I just turned the key on for about a minute or so and let it sit. The bike started right up.

Quick update:
Tried to start bike up earlier this week (the first time since I've had the problem) and it was having trouble starting again... turned over but no start.

I remember reading that someone had a similar issue and they were able to start it after leaving the gas lid open before firing it up (then closing it before riding away, of course). I tried it and it worked right away!

I immediately rode it over to Shell and filled it up with 91. It's been starting up fine since... I don't know lol

If that’s happening the check valve that’s supposed to let air in but fumes out as the fuel is drawn down is bad. Pay attention to see if you hear a whoose sound when you open the tank lid. If you do there is a vacuum in the tank and it’s impossible to pump gas out. The Aprilia V4RR was notorious for this same problem. Most people just removed the whole EVAP system.

Ducati dealers are aware of the this problem and won't tell you cause they don't know ethier at this point
