As the other guys say, remove the snorkel from the top of the airbox. I removed the small white side pannel piece off the RHS too, (about 4 inch by one inch) and drilled the airbox cover underneath to allow more air in.
For UK I run a 165 main jet, you may have this already in the US spec one, but the needle is different I amsure.
Speak to a UK dealer and order the needle for the UK model, or order a JD jetting kit off here! I think you will need to uncork the US can too.
Once all this is done, they are pretty punchy. Mine will pick the front up off the gas in the first 4 gears quite easily, up to 60+ mph!

Please could somebody tell me the location of the throttle stop may be pics if any
98% of the info in the 250F FAQ is applicable to your WR450F as well,
specifically for the throttle stop pics,

Cut the screw to 23mm (cut longer first then file it back)
Use a 4mm(?) allen key to turn it out from the bottom of the throttle body, it's loctited in so will be tight to turn.
I got a US model too and once you've cut the screw off you'll need to ditch the exhaust baffle or it will break off and fly out with the increase in exhaust pressure!
I fitted a www.quietiscool.com insert. Cost me £37 shipped
They restrict the US versions to meet stricter emmision laws, jetting is on the lean side too, I'm playing with different jets at the moment.
