Hi!
After years without bigger problems, i have no power from 4.500 rpm on. In the 3rd, 4th, 5th, 6th its is not possible to drive more than 6.000rpm. The motor feels normal from 0-4.000 but then....

What the hell could this be? I have no idea, maybe the ignition, or a sensor?

Need some help now...
Thanks

sounds like timing that's not advancing... might want to check there first

keep us posted

The Ducati Guy says its the frontside Injector; but I am not shure that this could cause that malfunction.....
Anybody had a defect injector?

Have you checked your fuel filter lately? They do block up and will restrict the flow of fuel to the injectors at high rpm & full throttle.

Mine was really blocked after a few years and I now replace every couple of years or so.

Worth a go.

Hi, solution:

There is a fucking metal fuel pipe inside the tank, which has a small leak now because of rust...

So there is not enough fuel pressure (only 1-2 instead of 3 bar), thats the reason why the engine does not run over 6000rpm....

The tank is a joke, there is lots of rust already.....

Hi again!

The ducati guy has made a bypass of the rotted pipe inside the tank and....nothing changed!
Still tere was a fuel pressure of only 2 bar. So I talked to a german specialist. And what he said was really remarkable & it was the solution of all the problems:

The fuel pressure regulator has a hidden screw behind an aluminium plate where it is possible to adjust the fuel pressure from 1 to 4 bar !

So we adjusted it to 3 bar and- what should I say it worked. The bike goes better than ever. It could be that the spring inside got worn out.

Every fuelpressure regulator has a (hidden) srcew!

Fabolous....
