Motorcycle Repair: starter motor, starter clutch, starter motor

Question
how do i reverse dc current flow in suzuki savage LS.starter.to make starter turn in other direction.

Answer
This is not possible.  You have to reverse the polarity and since the bike is wired with a negative chassis, you would blow other things up.  You can get the starter re-wound but why on earth would you need to do this?  The starter clutch will stop the starter from turning the engine in the wrong direction.

Good luck,  Jan
