Im trying to fine tune my carbs on my 1999 zx6r, but I'm having trouble taking the first step. My current mods are Muzzy full exhaust and K&N filter. My jetting is 145 mains, 120 pilots, and needle on the 3rd clip. Idle air screws are 3 turns out. At idle it is a a tad bit notchy, but not noticeable unless you try hard to here it. When I blip the throttle the RPM's do not dip before it revs or hangs before it comes down, it has good throttle response but It smells like its running rich. Also when I'm cruising at around 7k RPM I notice the tach slightly fluctuating like it is struggling to go over 7k RPM but when I snap the throttle it responses fine. What should I adjust or change. I was told the needles a long time ago, but I want to be sure first because the last time I touched one I broke the jet holder.
