I have had no problems with my bike at all. I have 2200 miles on it, cleaned the chain 3 times, adjusted it once, added a little coolant back at 200 miles, changed the oil and filter once, adjusted the throttle play a little bit, also adjusted the clutch once at the handle; and like i said no mechanical problems at all. It rides firm and tight just like new still. I rate it in my experience a 9. The only thing keeping it from being a 10 is because of the handlebar vibrations and the stock grips. I fixed the grips with some progrips and have weighted barends coming, once thats solved the bike will be very comfortable I hope.
