Problem with my 2001 Suzuki GSX-R600

[buc4933]

Here’s there problem, the bike is fine when your going along at 45 or faster, its when your going slow is when I have the problem. The other day I was riding it into the city and it started bucking or a hiccup as I’ve heard it called before, when I had a steady throttle on it. It felt as if you were just giving it gas real quick and then let off, and then keep doing it. Again it only did this when I was going slow, it even stalled on me a couple of times when I was coming to a stop. When I got home on the back roads I went slow again as if I were in the city and I didn’t have a problem with it. A little bit about the bike it's a 2001 Suzuki GSX-R600 with 5,600 miles on it. If anyone has any idea please let me know.
