Well I just got home.. I'm now in debt but I have a brand new 05 yz450F sitting in my garage.. I had a chance to warm it up a little around the neighborhood and I LOVE the power! This is a nice upgrade from my 01 yz250F and don't think I could ever go back.. Can't wait to get it on some dirt! Any suggestions for break-in, parts or anything I should know? Thanks to everyone for all the info I was able to get on these forums before I bought it!
