Re: top speed Yamaha Drive
Thanks, but where I live getting parts from the US is very expensive and not worth it, this is why i would like to keep the cart stock. Another cart on my estate can hit 65kmph, the guy says all he did was remove the governor, adjust the carb, do something with the exhaust and adjust the throttle cable. He wasn't very helpful or friendly but his cart goes fast. Which is something im looking for. Thanks

Re: top speed Yamaha Drive
There is no cart in the US that can go 40mph stock with a few adjustments. The only one close is a G1 yamaha which is getting pretty old, and it would take more than adjustments to hit 40. They can do 30 but not 40. But any newer cart with a 4 stroke there is no way without gears and/or lifted and large tires. They are 9-12hp engines and it is very hard to change that; that is why we have a big block section here you must change the engine to get more power/rpm.
Plowmans has a kit for more HP from the Drive, I think 15hp, but that still does not make it go faster. It is the same as your car in first gear it just will not go fast no matter what until you change that gearing ratio. |

Re: top speed Yamaha Drive
A g1 has a 2 stroke engine they modified from an old snowmobile design. It will get a lot of rpm that is how it can go faster in a stock cart. If you advance the timing and cut the head it will run pretty fast, if you work on the exhaust port it will go faster yet. I had one that went over 30mph and it was all stock on the outside of the cart.

Re: top speed Yamaha Drive
Read the sticky about modifying the bracket on the governor with a 5/16 drill bit. No parts required and no problems with rerouting throttle cable and associated drivability issue that some experience. I have the Plowmans clutch, carb and air box mods on my Drive, but the governor mod is a great place to start if you can't access parts from the US.

Re: top speed Yamaha Drive
Skeptic: I have a 2012 Yamaha Drive, stock speed around 14 MPH. I changed the rear end gear out to an 8/1 gear, 17MPH. Tighten the factory speed spring as far as it would go, 23MPH. I back off the speed spring to 20MPH because I was afraid of the spring coming out of the hole. Bought a Cart-Parts plus speed spring and installed, tighten so no thread showed on the backside, 27MPH with stock wheels. Have you ever riden a golf cart at 27MPH? That's fast. If I would tighten the Cart-Parts plus speed spring even more I bet it will go at least 30MPH!
NOW I am Believer, buy the speed spring if you want to go fast!!!!! |

Re: top speed Yamaha Drive
Its there, just like what is shown in the pics for all yamaha gas carts. You will have to get under the back of the cart and a light may help. Right on top of the transaxle. Tighten the 10mm not in relatively small increments until you either reach a speed that is acceptable or begin to get undesireable side effects like a jerky throttle response. Ultimately the best solution is remove and drill out the governor bracket as described in the sticky.
