mods for 05 wr450

just got one wanna know what some important mods are. and can the exhaust cam timing be advanced since it doesnt have a decompresion system anymore.

do a search for 450 mods there should be plenty of help

Go to It's pretty much got everything covered :)

It has an auto decompression cam which must be replaced by a YZ exhaust cam. Not a good idea to rotate the 450 exhaust cams like the owners of WR426 models can. :)
