Hey all, I bought a 2007 fz6 and has 9000 miles on it. Once its warmed up it runs fine. When its cold and you go to give it some gas, it stutters a lot. In neutral, if you can get it off idle and get the rpms up out of the stuttering rpms, it revs fine. What could cause this since its an 07 and efi...does it need calibrated or...?? Thanks for any and all help guys.
