Bought a used 2013. I noticed that bike cuts out at steady (low load) throttle...I do not know if it is electrical or fuel delivery related. Also the bike seems weak at the first 1/4 throttle opening...goes fine at full throttle... What could be the reason?
 
I replaced piston, spark plug and adjusted valves...
