Hello! My first post I own a 2007 DRZ 400 SM Black - last season purchase (1st bike), this year I noticed the throttle lag, twist - "pause" - accelerate. So I'm going to install the FCR carb for instant feedback (I assume I can still buy them). My question is this: I must do the 3x3 mod at the same time as the carb install, right? Thanks in advance, what a great forum this site is! Ben.
