Maybe you could consider looking at this very cheap modification I did, if you have the same pipe as the Aussie version.
To answer your question, yes I had to rejet to achieve the best performance from the bike.
WR450 muffler mod
i did that mod too,
didnt rejet though, goes just fine, starts easier,sounds good
$30 all up.
