Mv Agusta F4 1000 2005

Hi to all 🙂

I need your help

I have an Mv Agusta F4 1000 first gen

I had a problem with one of the injectors since the connector plug broke

Ordered a new set ( IWP 162 ) and since i had to remove fuel tank and air box i decided to do a service ( new oil 10W60 ENI, sparkplugs, oil filter ) .

Before the problem with the injector my bike was running like hell today it runs and after a while it stops

I just removed the sparkplugs and noticed this :

1st sparkplug : black
2nd Sparkplug : normal
3rd sparkplug : as new very clean
4th sparkplug : black ( burnt )


Please advice

Welcome to the family !!! Where on the planet do you ride your MV ??? Please add that to your profile.

#1 and #4 plugs are fired by the same coil. Likewise #2 and #3.

I suspect either you have a poor connection to the #1-4 coil, or the coil itself is failing.

Don't rule out the plug caps !!! They contain resistors for radio noise suppression. Maybe one of the caps was damaged during the plug swap. Resistance tests will tell.

I used to be fast....now I just dream about it.
