My 1198S has been having some issues while riding.

From 1st through 6th gear Everytime it hits 4k-7k rpms, the bike loses all power, and starts to jerk and lag. After turning the throttle all the way, it rips out of the lag and launches full blast.

This started to happen after my groomsmen after my wedding dropped it right after he changes my tire in the back.

I took it in to Ducati of Seattle & Belleive, neither which could find the issue.

It idiels perfectly, revs just fine, but as soon as you begin to ride, it loses power.

Any ideas what could be causing this??

First off, welcome to the forum!

Sounds like a fueling or ignition problem to me, but I can't imagine how something like that could come from a simple drop on the ground.

When it looses power, does it act as if you cut the ignition? If so, it could be the kickstand side switch, that could have been damaged when the bike fell over. You can test this by riding the bike somewhere without anyone around and hitting the kill switch on the right control panel to mimmic the feeling.

Thank you!

That was my first guess as well. I went and got a new fuel pump installed, cleaned the injectors, and changed the fuel lines, nothing change at all.

It does not feel like it engine is dying, just simply put, resisting power.
Once it get over 6k rpms it drives like its suppose to.

I'm getting both tires replaced tomorrow to see if that was the problem effecting the DTC. And I'll defintily check out the kick stand, maybe that might be it!

Shut off the DTC.....then try it. Also, take the mouse nest out of your airbox.

If it's just resisting power, I like the DTC idea a lot. Maybe one of the wheel speed sensors is unplugged?

Uh,..... think it might be magnetic........

The sensors have a physical plug for the wiring harness. If the front wheel speed sensor was unplugged, it could very well confuse the system just enough to cause this problem.

Changes the tires, didnt fix the problem.

hasn't the kick stand switch given this type of symptom?

Good call, especially if the bike was ever dropped. I've removed the switch from the street bike, and RTV'd a piece of u-shaped safety wire into the empty connector to mimic the stand-up setting of the switch.

I had a similar issue with the track bike recently, and since it was after a tear-down and as new build, I was chasing tuning, all sorts of stuff. It turned out to be the quick shifter cutting out with some vibration and also anytime my foot even got close to it. Look into this, and disconnect the QS if you have one.

The kill switch has also been known to cause cut-out sort of problems, one fix to prevent that was a backwards kill switch strategy that can be used in the Nemesis ECU and others so that if the switch fails or becomes disconnected in some way, the bike is still running, and the switch is essentially backwards. That's more bench racing than helful information probably, but gets us thinking of causes of such problems.
