Mine does it and it has since I rode it home. I've been told it's from the shower injectors kicking in and since I'm going to upgrade to a full Austin Racing exhaust and Aprilia Race ECU I've not worried about it even though it is very, very annoying becuase it bucks both on and off the throttle as you pass 6000 RPM's.

I've read about this problem being limited to the R models and not the Factory ones. Looks like DuctTape owns a Factory, so it looks like all models! Damn.

Yup, I have the factory and the buck. The dealership I got it from even mentioned it when I showed up toget her and it's my understanding the lag/buck is due to the the one set of injectors shutting off and the shower injectors kicking in.

The bike is not supposed to cut out at 6k. The original engine in my RSV4 did not do that, but the replacement engine would pause at 6k rpms, after a month in the shop, and new throttle boddies, the bike was good.
