So the question is . Are all the zx9R frames from 98 up the same ? pretty much is 98 frame and 2002 zx9R motor coompatible ?

Well I've heard that it was common for guy's with 2000 cracked frames to buy a 98/99 frame and swap everything over. Don't have any first hand experiance though.

The 98/99 frame had the tail section welded on and the 2k + were bolt on.

My bike is a 2k but the motor is from a 2002 or 2003 or at least the heads are since I have the front upper motor mount.

So they should be compatible but I can't guarantee anything.

Yes the motor will fit into the frame, but you are going to need the electronic (compelte harness,cdi,etc) off the motor. You are going to have to modify the gauge cluster harnes and headlight harnes if you are not going to swap those things out.
I would recomend that if your are going to do this motor swap go ahead and swap the gauge cluster and headlight to the 00up ones. It is going to cost a little more but save you a but load of trouble rewireing thing.
