I went through this on my Ka-t and it was pretty terrible. It would go way too rich in the low end, then lean out. I turned up the fuel map thinking it was tune related, but really my fuel pump was just dead and couldn't keep up. The first thing to do is figure out whether this is a tuning issue or something related to the actual mechanical engine. What are you using to tune?
