Ok..I am sure this topic has been discussed in the past, but I'm going to bring it up again so humor me. Is it worth the trouble to use race fuel in my yz450? I've heard pros and cons to using it in 4-strokes. I know the manual says pump gas is all that is required, but I always smell guys burning race gas at the tracks. Besides the fact that it smells better than bacon cooked outdoors whem camping, does it really provide that much more power? I've heard that if you do run it you need to change your jetting. Can someone educate me? Would I just be wasting my $$$$$?
