I know this isn't on the "current events" list but was hoping someone else had some experience with this and could share their experience. I did some searches but failed to uncover anything relative. Yamaha updated the intake boot (from the airbox to the carb) on the 2005 YZ450F from the design used on the 03 & 04 models. Question: did anyone have an 03 or 04 model who installed the new boot from the 05 and, if so, what difference did it make? I now this is a reach, but I figured I wouldn't know unless I asked!
