New F7 EFI owner (first Cat). Had the new rig out this a couple times just screwing around and put about 60 miles on it. Nice sled-really rips. I do have one question though. It seems like I get an occasional bog out of the engine (even after it is warmed up). It almost seems like a lean bog. All updates were done to it and when I asked the dealer he said its probably a question of getting the engine broke in and to give it a couple hundred miles. Does this sound like what people have been experiencing, or is there anything I could check out? Any help is appreciated.
