For those who want more speed. If you are thinking about the high speed magnet that is advertised and sold. Be SURE to check you motor carefully before buying one. They say to make sure your speed sensor is mounted with two screws. I though I did. What I was looking at was the screws that hold the retaining ring for the motor bearing. (wrong) DO NOT take those out.
As soon as I did I knew I had messed up. I will be taking my cart to the shop tomorrow to let them pull the motor to replace them. Good weather I'm going to play golf.
Just though I would post this to hopefully prevent someone else for making the same mistake. Thanks.
