Hey man. First, please don't type in all caps. Its hard to read, and online it means you are YELLING! Your question would probably get more results in the jetting forum instead of the mods forum. I've given up trying to give jetting suggestions to people, there's just too many variables. They can get you close but you will have to do the fine tuning yourself. Post this same topic in jetting and you will get some answers.
YFZ450's are fast to begin with. If you really want to put them to shame, put some cubs on your shee.
