I did this about two years ago now and wanted to post it here. When I did this the starter generator on my 1050 didn't charge the battery that well and I always found myself needing to pull the starter belt off so I could use a rope to start the engine. That was always a pain, so one day I had the idea to add another starter pulley to the front of the engine so I didn't need to take the belt off any more. All that I needed was another pulley that I already had and 3 longer bolts. Now I have a backup incase my battery is too weak to turn the engine over.
