I just bought a 2002 LC4-640 Six Days with only 300 miles on the clock! The head pipes are blue indicating the jetting is kinda lean. Is there a jetting kit I can buy or do you guys have any suggestions? It has a Supertrapp exhaust that looks heavy but is pretty quiet. I'm thinking there is more power to be found there. I've only ridden it up and down the street but the suspension feels kinda mushy. I'll probably take the suspenders over to Racetech for fixing. Many years ago I raced an 1989 LC4-600 and it ripped!
