I'm looking to upgrade my motor and with the kids riding this cart I dont need it going much more than 20. I've spoken to Andrea @ EMP and to Ricky @ Plum Qwick. It sounds like both companies could meet my needs. I live in Virginia Beach and own a house in South Carolina. Plum Quick is just off my route to SC so I could save in shipping by using them and if I had a problem then that would be same cost savings. I plan on getting a second cart that the kids won't ride and punching it out to 72 or more and I am going with a D&D when I start that project. Thanks in advance for you help.
