Nope, the mounts are slightly different. But, if you are handy with a welder, I bet you could make it work.

I think you would have to cut down the oil lines. You will have to make new engine sleeves for the swingarm bolt. put I think it should work.

Depends on the year. The 98-01 bikes use a 17mm bolt and the 02-04 bikes use a 18mm bolt (think I got the sizes right, but the 02-04 bikes use a 1mm larger bolt) for the swingarm.
