I had my stator and rectifier replaced 2017 because I fired them both when ik improperly getting a jump on my battery,ever since I had both replaced,it takes a little more time for my engine to turn over. Before replacement my bike would fire up like brand new,then after replacement it struggles to turn over.now that it's winter,it's even harder to start...so if anyone had this issue and know the solution ,please help..I thought changing the spark plugs would work but it didnt.
