Im stuck between buying an EZGO gas golf cart or a Yamaha gas golf cart..one person says EZGO's burn and suck valves and another person says Yamahas have issues? All i want to do is adjust the governor to get some more speed out of it and add a 14" wheel and lower profile tire....oh yeah, it will be a limo style cart. Does EZGO have more power than Yamaha (2003 to 2006 models) Is there a big difference between the 2 cylinder EZGO and the single cylinder Yamaha? Will they both run about the same top speed without modifications (other than adjusting the governor)? Any help personal reviews of these carts, the engines, etc.. would help.
