Just another newbie!!!

Hello everyone, I’m not really good at standing up in front of a big audience and talking about myself but then again I’m technically not,!! Well, my names josh and I have Recently bought a 2006 mv aGusta F4 1000 , It only has about 7000 miles on Her, She’s really beautiful bike all carbon fiber, Anyhow, I’m having a problem with it. If anyone could help me diagnose a problem I’m having with it that would be awesome.

So my Problem is this, when I started up runs fine as soon as it starts to get warm cylinder three cut off and will run on just The three cylinders

I’ll tell you a little bit Of what I’ve done so far , all I did was pull the spark plug wire one at a time and started up and see if around any worse or better and when I got to three it ran the same as it did with out being pulled .so I narrowed it down to cylinder three ? it’s getting spark on cylinder three I’m not sure about gas but I can’t see why when it gets around 150 degrees why it would cut of gas to just that cylinder but I haven’t done anything to check yet , I’m more hoping someone’s had a similar thing happen to them and could enlighten me
Thank you and talk to y’all later?

Hi and welcome.

I have nearly the same bike but am not technical enough to assist. You will get it fixed though.

Welcome, Josh. Congratulations!
After your problems get sorted it would be swell to see pics, but not mandatory.

You might need to have your injectors cleaned and have orings replaced. Its an easy send away process. Inexpensive. Mr.Injector does a great job. That said others will also chime in with additional possible solutions.

It sounds like your EBS relay is triggered.... The Engine Braking System works by Killing the #3 cylinder injector and opening a big air bleed into the #2 intake tract.

The EBS relay is triggered by the ECU when the ECU thinks it is called for. The relay opens the #3 cylinder injector power supply and turns on a solenoid valve that goes to the intake manifold.

The relays are know to fail when hot...... located right beside the cylinder on the left side of the bike, masked from air flow by the radiator and fairing panel.

A search will lead you to several threads in the topic.

Welcome again to the family.... find your manuals at Donsy's site (thanks again Donsy): Team Double 3 Racing | MV Agusta

And don't forget to add your location on the planet to your profile....

Thanks everyone for the warm welcome. I did some reading and am leaning towards the ebs also , my problems started when riding through Bay Area traffic on a 100 degree summer day temps got up to 230 and not much to say but she started to run like a #*[email protected] , u get the picture , the thing that I donít get it why will she run fine from the time I start her to around 150-170 degrees and the the three cylinder goes ? I understand the ebs function and all , so I guess what Iím really asking is ,do relays sometimes malfunction only to a certain degree (no pun intended)!????

From a dealer. Also, GP Racing (site sponsor) keeps them in stock I think. If not, and you can't wait, I'll ship you mine and replace it.
