Hi everyone!

I have a 2010 F4 with 15,000 kms. I just bought it like 2 months ago but 2 weeks ago it went out while riding. I was ridding on the highway, stopped to top the fuel tank, the bikes starts, i ride for about 5 minutes and suddenly it started to lose power, i was in 1rst gear, 120 km/hr, so i changed to 2nd gear, but i was still feeling a power lose, and then suddenly the engine shuts down but the dashboard was still working, and doesn't show any sign of error or warning.

If i try to start it, it tries and tries but the engine just doesn't start.

I search the forum and found that it could be the fuel pump so i replaced it, i tested it, and it's working, if i unplug the hose and turn the keys the fuel tank starts to "shoot" fuel from the pump.

The only "improvement" since i changed the fuel pump is that, sometimes, if i left the bike for 1 or 2 days, when i try to start it, it makes a little "explosion" from the exhaust, but that's all, it won't start.

For the fuel pump i used is a Delphi K9195 because it is interchangeable with the AIRTEX E8229 and the fuel filter is a Mahle KL145.

As an additional info, the bike has a Bodis exhaust, and when i turn the keys the bike starts to make a "click noise", the MV Agusta dealer told me that it was a check for the exhaust system, but that i can unplug it and it won't affect the bike, i tried it, and the noise disappears, but it won't start either, and a yellow light turns on in the dashboard, so i connected again the plug.

I attached pictures of the "click noise box" because i can't find the part in the MV Agusta official dealer. It's next to the fuse box, inside the frame.

I tried following the workshop manual maintenance, but i really don't know from where to start. Any help would be very appreciated!!!

When you turn the key to "on", does the fuel pump prime for three seconds?

Yes! i also tried turning the key to "ON" unplugging the fuel hose to check if the fuel comes out of it, and it does.

I am guessing this is not a fuel delivery issue.

What had been done to the bike immediately prior to the bike shutting off on the road?

What is the condition of your battery?

Nothing else, just the fuel pump. The battery is ok, i have an extra battery to start the bike without compromising the F4 battery.

I just don't know what else i can do, i looked to the workshop manual but i really don't know where to start, i checked all the fuses too and every one is alright. Including the ones next to the battery.

Trying to connect the bike to a diagnostic software could help?

Yes, diagnostics could help.

Just as a general piece of advice, the ECU has a low voltage cutout. If your battery is not up to the task, this can cause your bike to stall and not start.

The box you have pictured is the exhaust valve actuator. A servo motor that pulls cables to open and close the exhaust tuning valve in the mid-pipe.

The clicking sounds you hear are probably the internal gears slipping because the cables or valve are seized preventing movement.
The dash indication with the actuator unplugged is the ECU warning it does not see the actuator.
Try removing or disconnecting the cables.
The default position of the valve is wide open (spring loaded) so engine performance should not be impeded with the cables off.

Tomorrow I'll post a video with the bike trying to start, i believe is not an issue with the battery because it try to start but it just can't, the battery lose a little bit of charge sometimes and the difference is noticeable between a charge of 11.6 V vs 12 ~ 11.9 V so i just charge it to be sure it's working.

Regarding the actuator, i tried to start the bike with it unplugged, but i got the same result, as i mentioned in the begining, I'll post a video of it trying to start with and without the actuator.

I was looking for a diagnostic software and found JPdiag, is it good enough? Can i get some information about the problem?

And one last question, could the problem be the engine? And if it is the engine, can i solve the problem by myself? Or do you recommend me to take the bike to my MV dealer?

Thanks for your help!

What is the batt voltage when cranking?

Battery should be 13+ volts when fully charged !!! Just sayin'......

And I agree that the exhaust valve actuator shouldn't prevent the engine from starting. But disconnect cables, not unplug electrical connector, so no error code from "missing component signal" is created.
