Just got my final drive shipped to me from Henry. Have researched several different units and still can't decide which healer to get. I am leaning towards the 12 o'clock labs h1 model so those of you that used this unit tell me about it. If you used another unit tell me about it. Never have had speedo issues with previous wings help a fellow out. Ease of calibration is what I'm looking for, not having to drive bike and calibrate at the same time.Bike is 2016 comfort, navi,premium auto with xm.
