I have a 2005 h1 650. Trying to start it,it acts like the battery is low. Just clicks and may get a slight turn of the crank. Replaced battery and made sure of full charge. Problem is the same. Pulled spark plug and starter works. Can it be that the starter is old and weak? My next option is just replace the starter and hope that it works. Im at a loss and tired of pull starts.. thanks...Bill..
