If the swing arm pivot fits the the '02 engine, it should drop right in. If it doesn't, you can switch the steel collars that push into the crankcases at the rear hard point with the '01, and the whole thing will go as if it were made for the job. .

Yamaha's parts site shows the same swing arm pivot and bearings for both years.

The engine will fit, subject only to the conditions I mentioned.
