I just bought my son a 2004 yz85, the bike runs great until the upper rpm band. It hits the pipe good, pulls great to a certain rpm and lays down, in all gears. If he keeps it on a tight track, or off the straightaways it's okay. I have changed fuel, cleaned carb, changed fuel lines etc.... it doesn't smoke any more or less than comparable bikes. I am running 32:1 with Redline and Premium unleaded. Air filter good, fuel flow into carb good. I have mechanical ability, but this one is kicking me in the backside.
Please Help!!!!
