Cart too fast!

[x-bird]

I know most of you are saying "What!" We bought 10 carts a few years back for our 9-hole golf course. I'm now down to four. one of the chargers was marked "Fleet" and one of my carts is way faster than all the others. I wonder if it was a groundskeeping cart. I don't like my customers using it, but I do need it for them. What would I check to see if it has been modded for a speed upgrade? This cart comes back with spruce tree bits in it and scrapes from guy anchors etc. Our course runs outside our netted driving range, i'm waiting for someone to really do something stupid with it out there. My grounds help nearly backed over one of our deck mowers with it t his morning just pulling it out of the maintenance shed. I think this is also the cart that i posted about a few years back that really draws its charge down quickly. Still have to check on it, has been holding a charge normally so far this season.
