Golf cart speed is regulated by most courses at about 12 m.p.h. This ensures a reasonably slow speed for these heavy-bottomed vehicles and is typically installed by the manufacturer. But sometimes, you want the cart to go faster. To do this, you need to modify the speed governer that prohibits the engine from revving at a higher r.p.m. However, doing this may damage your engine if you consistently over-rev your engine. Read on for an overview of removing or modifying the different regulators, specifics vary due to manufacturing and engine details.
Step 1
Open the panel that covers your engine. Typically, there's a flat panel behind the seat that you can remove using a flat or Phillip-head screwdriver.
Step 2
Access and adjust the spring. The most common type of ground speed governor is an adjustable, mechanical, spring-loaded governer. It is most typically located running in parallel to the golf cart's acceleration system; either at the carburetor or pivoting from the differential. Adjust the tension of the spring by hand or using a wrench and test if the speed is increasing or decreasing. Once you've determined which way to turn the spring, turn it until you've reached a more acceptable speed.
Step 3
Adjust the clutch and throttle cable. Commonly used on two stroke carts, this governor resides next to the secondary sheave, or driven clutch. Use a wrench to turn the cable nut that attaches the throttle cable. By lengthening the cable, you allow a higher top speed as more gas is delivered to the engine since the throttle lever action will be minimized.
Step 4
Talk to a professional. If you have a spark regulator that acts as the governor for your cart, you won't be able to modify this on your own as it's an electrical device, not mechanical.
Step 5
Buy a bigger engine. The safest method is to move from a 295 cc engine to a 350 cc engine. The bigger engine provides more power, and thus a higher top speed. While you can install the engine yourself, most mechanics can conduct the swap in about an hour and a half.
