According to http://www.powersportspro.com/pages/parts/viewbybrand/2/Yamaha.aspx (http://www.powersportspro.com/pages/parts/viewbybrand/2/Yamaha.aspx) it will work.

Look up your part # once, then enter it in their "Quick Part Lookup" and it'll list all models that use it.

In 2000 Suzuki reduced inertia in the crank by 5%. This basically balanced out the crankshaft for more power. I believe that is the only difference. The only noticable difference in the engine is that the piston in a '99 is a dome design and a '00 is flat top. I think 96-00 cranks are all interchangable.
