I have a 2003 FZS600 and recently purchased a 2007 S2 FZ6. The FZS throttle response is smooth and predictable but the throttle on the S2 is just the opposite, it seems to have a dead spot when first turned then suddenly takes!. Not good when you are trying to smoothly increase speed coming out of corners. Anyone had this problem or any ideas on how to smooth out the throttle response?
