Recently got my first road bike a 2014 ninja 300 w/abs. I ve noticed that the clutch lever has a lot of vertical (up and down) play. I have tried tightening the 10 mm and 8mm bolt and lock nut on the lever handle but have had no success in moving either. Do I just accept the vertical clutch play or is there a way I can tighten this down I haven't tried. Its not the cable as I can easily engage the clutch to shift just find it bothersome that the clutch lever moves up and down which I might just accept. Any help is greatly appreciated and thank you.
