My 06 just turned over 4k miles. On the way home today from work I left a stop sign after about a 20 mile ride. I gave it a lot of throttle in 1st and it reved freely like I had the clutch pulled in. I thought I span the tire but at about half throttle in 1st and 2nd and hardly any throttle in the rest of the gears the bike will rev to the redline with no acceleration. It shifts fine and launches fine as you dont give it alot of throttle. The bike is completley stock and I changed the oil about 300 miles ago to maxima dino oil, jaso for wet clutches. Any one have any ideas? I tried bleeding the clutch but it didnt help.
