And you are aware of the aftermarket support for those engines, arent you? If some is good, more is better! And too much is just about right! |

Please tell me someone makes an installation kit that includes some sort of transmission with reverse.
I have a late 60s vintage Taylor Dunn electric cart that has $700 worth of dead batteries and still has the original wiper style speed control that is a giant PITA. Part of me would love to make a gasser out of it but most of the ideas I have had have been thwarted by lack of a reverse gear. Funfact: My cart came standard with a Currie built Ford 9" rear axle. |

I thought about doing a build thread for mine. Also a 91 EZGO, but mine is a marathon. Electric. I built a custom lithium battery pack using cells from a Nissan Leaf EV. It's up and running great (goes 19 with stock motor). It needs body work/paint and electrical accessories (lights/radio).... Maybe a new motor for more speed

If it's top speed you're going for, you'll want either/or bigger tires/taller gears. Otherwise that big motor will just be good for getting you up to 19 mph really quick and any mods you do to the motor won't do much more for you unless you modify it to run at much higher RPM which is going to be big bucks. That V twin will rev to about 4500 stock so really not much different than your stock motor (if you eliminated the governor) which means your top speed will remain roughly the same unless you put bigger tires or taller gears or both. V-twin would probably have the power to get you a 50 mph top speed if geared correctly.
Gear swap isn't too bad. Pretty straight forward. Just messy and takes some time. I have the Kawasaki 290d with advanced timing, jetted carb and header pipe/motorcycle exhaust with 8:1 gears and 25" tires that tops out at 34 mph. Takes a city block to get there. Eventually will get the 600 ish CC single cylinder engine to take the place of the 290. Don't want the V-twin as on my cart it requires a lift. For now the 290 is sufficient, gets up to 25 pretty quick and will slowly climb from there, can still climb steep hills. But if the motor blows, it'll be a fun day swapping in more power. It's plated and we put 1000 miles on it a summer and is an absolute blast to drive around small town and gravel roads. |
