That is what I have been hearing here. I asked the shop to do that and when they dynoed the bike they said it did not need to be rejeted?? I ran that jet tool Dog sent to me and with the elavation I live at 6000 it also told me to rejet. Shop showed me the graph and it did not look way out. running about 53 hp. So I will pull a plug and see ... If it is way gray running lean right, or black rich. I know rich from running KDX and high oil mix for the desert. It erks me to go to a shop and they try to tell you what "you" want!!! Trust you guys here more than them.. Let me know
