Default Modifying Governor on G16 & G22

Here is a way to modify your governor to be wide open without having to play around try to figure out how to re align the throttle cables

1- Loosen the 10mm nut if you already have it cranked up , (it need to be stock)

2- Remove the plastic black cover at the back & remove the basket if you still have one

At the lower part of the governor there is a bolt with a 10mm nut you loosen it so you can pry up the governor about 1/4 of an inch of the shaft you will notice that it is D shaped you take a 5/16 drill bit & round up the bracket so it will spin freely on the shaft
Put it back in place
Use a little lock tight or nail polish on the bolt & just tighten it by hand to keep from loosing it
This way you have full throttle no restriction & all runs smooth like before,
Change you oil to synthetic 1 liter of 10w30
Very important don’t hold it to the floor going downhill not to blow it up
Good Luck Cart de Golf

this might work on other models I havent tryed it

It works on most Yamahas. Some carts you need to put a spring on the arm to keep it from lifting off the shaft, and some to also act as a return spring as some the governor does much of the return force even at rest. A G9 needs a spring for both issues, but a simple automotive carb throttle spring works well. That said for me this method has worked better than putting the cable on the carb.

make sure the shaft spins inside the governor no hold back

for 30 mph you will need to do air cleaner jet ect.

What is the risk to the engine when bypassing the governor?
Thanks

Just be mindful of your RPMs, and don't hold the throttle wide open going down hills.
