I have a 2000 r1 that I'm think of sticking a freshened engine in. They are harder and harder to come by. Visual they look the same as 02-03 cases but part number wide they are different. I know cylinder heads are different, but I just want to use the crankcase. I've got a guy with 02-03 under 10k miles for good price. Just want to see if anyone has done the swap, I know the heads are different, that I will swap over. Anyone have first hand experience. Thanks
