Hello everyone! Guys, please help me! My Panigale V4S behaves very strangely, at high revs when slowly opening the throttle the motorcycle makes strange sounds, similar to hum and bubbling, it seems that the sound comes from the exhaust system and the fuel tank, when I open the throttle this sound appears, and if I keep the throttle slightly open this sound is constant, and when at high revs I open the gas the motorcycle makes this sound and starts to go with a delay and a sharp jerk. I also noticed that the motorcycle began to go very badly, it lacks power, as if something is holding it or there is not enough fuel, especially in first gear there is very little torque and power, on the Bapro dyno the motorcycle showed 197 engine horsepower. The motorcycle has T800 firmware and Termignoni D184 exhaust. I may be wrong, but this problem appeared after the service removed my fuel tank to install a carbon engine covers, I had problems with the smell of gasoline, I was told that the Evap hose was not connected well, they fixed it, but the motorcycle behaves as if in low power emergency mode, please help me!))

I don't know exactly what your problem is but it does seem fuel related. If you didn't have a problem before the work then perhaps that is the starting point.
Remove the tank check the connections and the routing of the various pipes to the tank, could it be contaminated fuel or a dirty filter?

.... that, comrade. You'll illegally arrest me for being a spy and throw me into the gulag or poison me.
 
Friend, what are you upset about? Personally, I have a lot of American friends, and I have excellent relationships with normal people. If you need to talk about politics, do it somewhere else.

Should I look at the fuel system? The bike is acting really bad. Could there be a problem with the EVAP?
 
Possibly, it would seem logical to troubleshoot by going back to when the bike was running well and if it changed after the tank removal then look there. You could try removing the evap and see if that changes anything. Its only 20 minutes work.

Unless you are living under a liberal rock and think the real world is all about the right to be a trangender dwarf even if you are a 6"6" bodybuilder, it's pretty hard to ignore geopolitical reality that other people have different beliefs and values to Californians. The Russkies and the Banderites will sort it out in their own good time i.e. it's none of our business and IDGAF.

when removing the fuel tank everything seems clear and simple, what mistakes could have been made?

Friend, you might find the solution to your bike's problems in the trenches. You coming on to this forum and telling me what I can and can't talk about sounds about right from a privileged oligarch's kid.

It's cute seeing Paul trying to diagnose the vaguest of problems when OP has no clue what he's doing. No offense, but it's the blind leading the blind. How about you take the tank off and try fixing it first before posting on here? Or even better, take it back to the ..... that worked on the bike and have them fix it. That would be the smart thing to do. If you or them can't figure it out then ask specific questions.

And more importantly, that Ducabike clutch cover is the real war crime here. This dude needs to be sent to The Hague

lol, clear covers are a war crime but as you say its a very vague description which is why the Hansel and Gretel approach is suggested. Follow the breadcrumbs back to when you weren't lost... but to be fair if you haven't got the skills to remove the tank then it's not going to be easy. The OP hasn't given us much of an idea about the mechanical skill set he has.

You must have lead marbles for a brain, Boris. I think it’s very obvious my contempt for you sneaky ....... Russians. You could solve the problem by growing a pair and go to the front lines to serve as cannon fodder like your brothers that have been forced by Putin’s conscription.

How many miles are on the bike? Does it only do it when hot?

Your problem sounds like there's too much pressure building in the tank leading to a sort of vapor lock condition, which will be very noticeable when warm. The EVAP canister is choking off the bike. Very common mod to remove them.

Put the troll on ignore. Most everyone here already has.
