2015 F4R failure exhaust valve ????

How common is this problem and also rear break is not workin as well. Call me a bit disappointed because from the delivery nightmare to now no rear break and suddenly a failure exhaust valve malfunction has me really thinking I made a mistake buying this brand new 2015 F4R last fall. All these issues with a dealer that doesn't care to respond to my calls and to top it off there isn't even a authorized dealer anywhere close to me So even to service this bike under warranty is gonna take shipping it 500 miles at least to the nearest dealer smh. So with that said does anyone have a clue on how to actually go about fixing my issues. I'm in Detroit Michigan USA so even advice on having it serviced would be helpful. Sad to say at this point I wish I would have bought a fucking Ducati because at least I have a dealer 6 miles away yet they aren't authorized to do any type of warranty work to my F4 Thank u in advance for anyone willing to help me tackle this nightmare that shouldn't even be happening with a BRAND NEW Bike let alone an exotic machine as an F4. I feel like I just bought a Lamborghini brand new only to realize the headaches of lil shit that shouldn't be happening to a machine with only 1200 break in miles on it. WTF

Just disconnect the exhaust valve cables... Bike runs & sounds better without the contraption anyway... http://www.mvagusta.net/forum/2193241-post10.html

Maybe your rear brake needs bleeding... Simple maintenance??

These are good bikes, more exclusive than a Ducati. You just need to show her some love & learn how to cope with the foibles! :-)

The problem with the brake is known to all MVs. The brake flyid container is too close to the exhaust. So the brake fluid loses its function with too much heat. Most people solve this problem using the foot brake.

I also have problems with the exhaust valve on my F4 MY11. I have not fixed it yet. But I'm 99% sure that the actuator that controls the valve is deserted. This is a warranty case for you. How to solve this when the dealer is so far away I can not help you with. But I wish you good luck.

This is what I think you need to replace. Nummer 28.

Do you notice the actuator makes a sound if you turn the key. And do the sounds continue.

That is where the actuator lives on all of them. If you simply disconnect the actuating cables, you should be fine. Leave the electronics alone.

As for the rear brake, as others have said, change the fluid, bleed the system thoroughly. Some have had success removing the master cylinder and inverting it to bleed all of the air out. Even a minor amount of air is detrimental in such a small system.

I just went back to read the OP. Man-o-man. These machines are easy to work on. Learn about them. Do some research on here to find the manual (top of each maintenance section).

If you are at all competent with a wrench, the minor issues that do crop up are easily remedied.

Not sure what happened to my last attempt to post but I was all good with disconnecting my cables and had nothing show up on my cluster. However today I went for a ride and the weather isn't as hot as it's been and sure enough exhaust valve failure came up again. So now what ??? Should I ship the bike to get warrenty work to fix this or is there something else I can do ??
