I changed my jetting to the 48/170 before I even started it the first time. I found this to be too rich. Went to a 45/165 or 45/168 depending on the weather. I found my bike runs crisper with the 45 pilot in. I have a little popping on decel, not much. I can usually tune it out with the fuel screw if I really try. Every bike is different but when my bike is running the best it will have a little popping on decel. I can't really speak on how the bike runs at a steady RPM because that is not how i ride it. I ride some pretty tight woods and am either on or off the gas.
