If your Harley has suddenly started to kick-back on a HOT start that sounds & feels like something in the primary is coming apart , you know , that LOUD CLANK-BANG ! Don't just blow that off as normal Harley sounds . If it continues to do this intermittently be forewarned that sooner or later the "STATOR" and or the "COMPENSATOR" are on there way to destruction & will damage the "RECTERFIER / REGULATOR in the process leaving you stranded even with that brand new fully charged battery ! Ask me how I know ! :cry Hey , its only money !
