I am first to agree that with the same year model bikes, same fuel, same weather, and same elevation - the jetting can be slightly different. I see everyone is running a 168 main and 48 pilot. You are way off at sea level and higher with warmer weather. 65 DEGREES and below with the 160 main and 45 pilot (WHICH, BY THE WAY, IS STOCK) are on the money with mine. Rode in 80 degree weather and with the 160 main it was slightly rich. (power hit a slight wall, and didn't quite pull all the way through) In tight blip areas, the 45 was flaming out on me. This is what I have when above 70 degrees - 155 main, 40 pilot - and my motor sings. I am not running pump fuel, the fuel I am running tends to run a little rich. Regardless, even running pump fuel, I cannot see how you guys are running clean with a 168 main and 48 pilot in warmer weather. The needle and clip position are both on the money. As far as these big companies giving jetting specs, do not take their word for it, do not even take my jetting specs - move those jets up and down and pay attention to the feel and sound of your motor. One more thing, do not go by plug color on the insulator tip. You will be chasing your tail if that is how you are going to jet. In addition, set your accelerator pump timing by the manual.
