Anybody got any suggestions for carb set up for a 2001 with Muzzy full exhaust and K&N filter. I am used to FI, so I am kinda old at this. Jet kit..what one would be best also. It runn good I guess but stumbles down low and feals a little sluggish, not bad. I am just used to crisper responce. I will pull apart next weekend to adjust valves, tune carbs, ect. Thanks for any help.
