I know a 2002 fits no issues, thats what I ordered.
No mods needed at all either.

Make sure you guys check the auto tensioner over to make sure its springy and check the guides for wear. You suspect anything is bad replace it.

Im my experience what caused the tensioner to fail on my friends 400 was the timing chain was stretched.
We put on another one before swapping the chain (brand new) and it failed too after like 3 rides. Put on a whole new chain, guides and tensioner he got used and no issues.
What I think causes it to fail is it pushes to hard against a stretched chain and breaks. Comparing the worn to the new chain we could clearly see the old one was just slightly longer.
