Like you, I also like to tinker and would recommend the following projects for your cart.

First and most importantly, change your rear differential oil and use Yamaha Friction Modified gear oil. The cart has wet brakes that are lubricated with the differential oil. The brake system is excellent but does require periodic oil changes.

Check your charging voltage. My 2014 EFI was charging at about 17 volts, which can significantly shorten battery life. If you do a search, Villagetinker started a thread on this with a wiring diagram of how to fix this issue. After his fix the cart now charges at 14 volts.

Replace the brushes in your starter/alternator. They are probably getting close to the wear lines on a 2013. There are YouTube videos that show how to do this.

Think about replacing your secondary clutch, the older clutches are held together with only 4 rivets and can blow out when they get older. The newer 6 rivet clutches are much stronger and more reliable. While you’re doing the project, put a stiffer spring in the clutch and replace the drive belt with a better heavy duty aftermarket belt. Your cart will have much better torque after the fix, which is noticeable going up hills with two passengers and golf bags. This won’t increase your high end speed, just the torque. While you’re doing this, throw in a new starter belt just to be safe. All the parts for this project can be purchased online from powerequipmentman.com.

Ride on : )

My cart 2012 1/2 if has 6 rivet clutch. In my case it was snap ring groove that wore out and let clutch separate.
