My Yamaha G22 golf cart is painfully slow, and I’m feeling left behind in my neighborhood rides. I’m not aiming to race, but a decent speed boost is essential for safety and, let’s be honest, a bit of fun. Has anyone successfully managed to ramp up their G22’s speed and torque without spending a fortune.
Response
I faced similar speed issues with my G22. Upgrading to an Alltrax XCT controller was a game-changer for me. It’s reasonably priced and significantly enhances speed and torque.
