lyk u said he trained 2 attain dat speed so without sharingan he still has the speed:| meanwhile Kakashi just stand by, wait, reading Icha Icha Tactics :|
Kirin takes time to be ready, Kakashi can easily kill him off with speed before that
Kakashi at the age of 13 had naturally the speed required for Chidori as stated by Minato
Sasuke at the age of 13 had to use sharingan to copy Lee's taijutsu in order to train with it and gain that speed you are talking of.
Since this thread is about them without sharingan, he loses it :|
