Anybody have any advice on these bikes? I'm looking for a bike with more power and torque then my 6R, but still retain many of the same comfort qualities that attracted me to the ninja in the first place. I found a 2001 for $4K, that's in mint condition with 4100 miles on it. The only problem, well, it may not be a problem, but it had its first oil change at 3500 miles. Is it worth my time? I know the first oil change is most important, so is there any damage inside the cyilnders and crankcase from the metal shavings?
