Bike back from first service where it had SE211 Cams fitted. OMG its a different bike!

The power is amazing, I find myself quickly switching into third and backing off as it now goes so bloody fast! At the very bottom end the motor seems a tad weak but only for the first 1000rpm or so (dont have a tach so not sure), but could just be that the response is so strong that it emphasises the difference? (yes I know that there are endless threads about the best cams but that's what the dealer recommended and I dont lose any warranty) Anyway have to get a lot more k's on the bike to get to know it all over again so will report back.

Can anyone confirm whether its likely I've lost power low down to gain the mid range? Or is it just that the rest of the acceleration is so strong that itmakes the low end seem weaker?
