I just purchased an 05 wr 450F and have heard many people talk about the many mods (clip the greay wire, change the throttle stop, and modify the airbox among others). Does anyone have any info on the 05? Is everything still the same? Also, do you purchase a new yz throttle stop piece? and what do you do to the 05 airbox? This is my first 4 stroke so any helpful advice would be much appreciated!
