Hyundai cart restoration
 
3 Attachment(s)
New here, but found the site helpful and thought I'd document some of my own finds for this fairly uncommon cart.

Current issues I'm working through:

-voltage regulator sending battery 17+ volts
-smells of gas
-seems to run rich
- touchy throttle
-shocks are shot
-add back seat
-add amp and sub

Already resolved:

King pin and bushing replacement
Fit 14" wheels with low profile tires
Wired in stereo
Wired lights

Still have to figure out the abrupt engagement from a stop, but Im working on the air ride now. Here it is as laid out as it can go without any front modifications made to clearance. It should go lower if I narrow the front or do some body work.

New voltage regulator also solved the over voltage issue.

Welcome! That looks like a fun project. Reminds me of the Yamaha G2/G9 body style.

It seems to share a lot of components with the Yamaha G2. For example it has G2 Rear shocks, but at all 4 corners.

Some of the old hitachi? voltage regulators were adjustable, for sure on the G1.
the cover would come off and you could adjust it with the small slotted screw.

Golf courses would bump up the voltage to help keep the batteries charged on those short runs

I didnt see any adjustment on this one when I opened it up, but that is good to know.

Front air ride is installed and controlled by a schrader valve for the time being. They were a drop in fit running them upside down to typical. Ill use the same air shocks for the rear but will require trimming the sleeve down.

Still trying to resolve the touchy throttle, it clicks and disengages the engine at light throttle, and re-engaging click it wants to take off again. maybe its just the setting of whatever switch controls that? All air ride on, not sure if i like it or not, I was hoping it would ride nicer. Back seat also on, ordered a kit for a yamaha and made some modifications.

Make sure the activation switch for start closes before the carb starts to open. Should solve that problem. Probably just a throttle cable adjustment. Make sure you still get full throttle with pedal down.

What wheels did you use?

Do you have any info on the parts used for that? My Hyundai has slop in the pins that I would like to sort out.

Mine is the same way. The Mikuni I would re-jet but I am having no luck finding any info on the carb, or smaller jets that will fit it. I am using a rigged-up Amazon carb now but would much rather rebuild the Mikuni.

My cart also feels like someone is popping the clutch when you try to start off. I am not sure if it is a worn belt (mine measures a touch over 7/8" on the outside), or a clutch engagement issue, but in a video I watched of a Hyundai cart, it began moving on it's own with the starter engagement, and then when the engine caught it moved faster but there was no sudden engagement jerk happening after the engine had started and built up RPM... it slowly crept forward under starter power and then the engine caught and it smoothly transitioned into forward motion... so I think that is what it should do and I hopefully can sort out what is happening as it is annoying, and adding wear to the parts with the shock forces.

Thanks for any info on the kingpin fix:thumbup:
