I think that everyone that owns a recent Ducati SHOULD disable or remove the exhaust valve.
It frees up the engine on low revs.
Put the bike on the side stand and stand on it's right.
Rev it slowly and at the same time look at the side of the valve, you can watch it moving and understand how it messes up with the engine.
This feeling that the engine does not want to rev freely past idle at light throttle opening, the feeling of the sound disappearing at some revs...Its all the valve's doing! Unplug the thing go for a ride and if not convinced, plug it back in.
Actually we, monster 1200 821 and Hyper 821 owners, are very fortuned as unplugging it won't produce a warning light on the dash. We don't need a Duc.EE to eliminate the light. Maybe Ducati realized that the majority of owners are disabling it and made life easier on us...maybe!!!
