I'm new to the forum. In fact, I posted a similar message to the wrong area yesterday.... I just got my NEW 2015 fuel-injected 4-stroke 357-c.c. Yamaha-drive PTV. The speed governor on the cart is "factory set" to a mere 12 m.p.h. Hey, I can almost run that fast! The operator's manual says the "Maximum speed" is 19.5 m.p.h. Any suggestions from my fellow forum members would be GREATLY appreciated! I almost got rear-ended by an EzGo the 1st time out. HELP. Best regards.
