Can a 1993 cbr 900 engine be put into a 1999 cbr 900? If so how much needs to be changed for it to work?

 

i have a 93 900 with a 99 900rr motor in it so yah its possible

 

your gonna need the computer and harness for the 93 motor, also you are going to have to change the 93 speedo pick up to the 98-99 pickup if you want a speedo. Why are you going to put a 893 in instead of find a 919? Really just a matter of bolting it in there.
