Hi All, I`m not going to complain how fuel inefficient the ZX-14 is. I love the bike and the power it makes. But mine seems to use more gas than some others. The new 12-R was tested in the mags to be 36-40 mpg. Honestly, I get 31-32 mpg and that`s mostly on the highway doing around 80 mph. The computer says I average 39.5 mpg but the MOST I ever got was 38 mpg on a long road trip. I have a Muzzy full system and map and a Dyna Jet Power Commander. The bike runs good but the end of the pipe is always black. My buddy says it smokes a little when I get on it. My old ZX-11 always got in the 40`s and got 50 on road trips. Should I look into a different map or maybe an Auto Tune? Thanks in advance for any help. Lou D
