Well, I picked up my long awaited '09 250r ninja yesterday. While I am not mechanically inclined simply because i have spent very little time doing it, i am even less so w/ motorcycles. This is my first one, i have had it for almost 24 hours, and have put ~70 miles on it, doing the 4k rpm break-in. I have noticed though that my speed and tach reading (while in 6th) vary greatly (5-6 mph). There is no incline/decline, flat surface, w/ minuscule wind change. What could be going on? Answers anyone? anyone experienced the same thing?
