These drive clutch rebuild parts are for later model G1 & G3 (Sun Classic) 2-cycle gas, and models G2, G5 (Sun Classic), G8, G9, G11, & G14 4-cycle gas Yamaha Golf Carts. This drive clutch can be identified by the dome shaped dust cover that is held in place with 6 screws spaced around the perimeter flange.
The earlier model drive clutch did not have this particular dust cover. It has an cast aluminum cover with a single retainer bolt that you can see. The flyweights for this model are no longer available.
Each flyweight kit includes one flyweight, one spacer & four plastic washers. You also may need the two pivot pins, one long and one short, that hold each flyweight in place. Please click on the picture for another view of the flyweight. These pivot pins are NOT part of the kit but you may order them from the drop down menu at the bottom.
Please select the kit only, the kit with the pivot pins from the drop down menu and then type the number of kits needed in the quantity box below. There are three used per vehicle.
This repair can be used with the clutch on the engine, in the cart.

Note 1: A telltale sign of a bad flyweight is a crack or dent (coming from the inside) in the side of the gold colored metal dust cover. If the dust cover does have a crack, it should be replaced. The added weight of a weld to repair the crack will adversely affect the balance of the engine. Please click the following link to get to the Yamaha G1-14 Drive Clutch Dust Cover page.
Another symptom of a bad flyweight is poor performance, especially up hills or under a load. If the engine does not have its normal get up & go, pull off the dust cover & check the flyweights. TIP: The phillip head screws that secure the dust cover can be too tight to break loose with a screwdriver. Squeeze a small "Vice-Grip" pliers on each screw head to break it loose, then use a regular screwdriver to finish the job.
If one flyweight is worn, or has broken, there is a good chance the other two may be excessively worn too. Usually the weights will get wobbly on their pivot pins and the holes will elongate. Careful examination will reveal this condition.
NOTE: If you need to replace either the Drive or the Driven Clutch chances are the Drive Belt needs to be replaces as well. Check the old one for cracks and splits.
And if the Drive Belt is bad, check the Starter/Generator Belt as well.
