I bought my wife a 2008 Nighster 1200N a couple of months back. I occasionally ride it. It is stock with the exception of pipes put on by the dealer. They were already on the bike on their show room so i am not sure what they are, I just know they are alot louder than any of the other nightsters I had him start up. Anyway, here is my question. I drove it to work today and there is an area where the speed limit is 15 mph. I have noticed at low speeds. ie, 20 and below, the bike just sputters all over the place and sounds terrible. I got to the point where I would just bump the clutch through this area and idle through. This does not seem normal to me, I should be able to cruise at 15 mph in first without the bike sputtering and lunging through. Or is this just the 1200N way that I have to get used to. It just seams very out of tune but since it is fuel injected there really is nothing to adjust. Thanks for any resonse in advance.
