OK guys you all know what I have been doing with my bike. Mainly carb jetting is my issue now. Everything is clean, main jets are 126's across the board, FP jet needles, number unknown. The needles are set on the third from the top and I can't for the life of me figure out why according to O2 AFR gauge it read lean at 8K RPM at full throttle, after cruising with a friend of mine for a couple of hours in traffic.. First start up and with a cold engine I can break the rear tire loose and drift the bike if I wanted to. After warmed up to about half on the gauge and burning my legs on the frame, Shes a little rich in the mid but pulls great to redline. It's something to do with the heat generated while sitting in traffic.. Could it be I am chasing a carb ghost and need to look at ignition?
Let me break it down and hopefully one of you carb gurus can help
