MV Agusta F4 Wellnut Fix - this could save your engine!!

This video is for anyone with a 1st Generation MV Agusta F4. It is a MUST fix and could save your engine from a lot of damage. The 1st Gen F4s have a design flaw so extreme, it can permanently damage your engine. The fix is so simple, you’d be crazy not to do it immediately. The Wellnuts that the screws holding the plastic injector covers screw into are made of rubber, with a brass threaded insert. Through degradation, the rubber can deteriorate and the brass insert work its way loose from the screw. If this happens and the brass insert falls into your air box, it can easily drop into the intakes and cause irreparable damage to your engine.
