What's up? I have a 2002 RK that is carb.ed. I plan on going with a stageI setup. Would it benifit me to go with an aftermarket ignition module? If so, which one and how does it increase performance? What is meant by single and dual fire systems? Now lastly, am I correct in assuming that you should upgrade the coil? Any information is appreciated. I have a limited understanding of this and would like some insight. Peace, J.T.
