Golf Cart Conversion Yamaha G22 Electric to 7HP Gasoline

- Electric motor failed in my G22, so I converted it to an electric start gas engine. The mod utilizes #35 chain drive with a centrifugal clutch, and go-cart transmission. Whole conversion cost about $250, including engine! Sold the controller and motor for almost $1000, and kept the 6 batteries for my off-grid system. Win/win... never looked back! LoL
Would like to see more about your drive system, sprockets, brackets, etc. I am about to do what you did as my batteries are shot and has been sitting a few years. Good Job!
I used the same trans on mine except I used a torque converter clutch and belt. Then a #40 chain to the rear end coming from the trans. Awesome job!
Chris, yes, that #35 chain that I used is a little light for the job, but still working. The only thing that I have had an issue with was the clutch. I had to put a replacement clutch in because the centrifugal clutch sprocket wore down very quickly, on the inexpensive Chinese clutch. I like your approach better, with the belt-drive and torque clutch, because that is where all of the stress is in the system, as you know. Way to go Chris!
what transmission is that ,i got a ez go cart that im converting to gas and what did you do to connect it to the the rear end where the electric motor went ?thanks i need ideas!!
It is easy... I just used an angle grinder to carefully grind down the splines on the differential input-shaft. That way I could just slip a chain-drive sprocket over the shaft, and JB Welded it in place (as well as tightening the set-screws that came with the sprocket.)
thanks i want to do the same set up but i want to use a torque converter
I'm with on on that torque converter call! I am going to be switching over to that myself. The centrifugal clutch works for flat-land applications, but if you need to go slowly, and need power, the Torque Converter is the only way to go... and for just a few dollars more!
Yeah I picked up my torque converter kit on eBay for around $65 new. Performs flawlessly. Fits right on the forward/reverse trans too.
Awesome Chris... glad to hear that! I am doing the same thing asap!
Chris Pearson I'd like to have more info on this
Brian Matheny I actually bought a torque converter kit on eBay. But then I found the f/r trans on aliexpress and ordered it too. The pulley ended up fitting the trans perfect. Email me at 89mirageman@live.com and I'll send you some pics.

Can you seen me pictures

I know it’s been a while since you posted this but also interested in torque converter kit also.
Any tips on what brand or manufacturer or better yet a link !
took a 1968 harley davidson gulf cart and put a 7 hrs duro max on it had to change mounts heavy duty throttle only thing cant back up working on that now
Good job on the conversion.
This is the first build that I have been able to find where the forward and reverse still work. I myself am not mechanically inclined. can you provide more info on how you did that. I have a club car I just started stripping down to start my build
Tim, thanks for your comment. I need to shoot a real video, where the exact process is detailed, but have just not had time to do it. Here is the secret to Forward and Reverse... the mech is for a Go Kart, and works well:

I have the exact golf cart and would like to do the same thing. Will you post a parts list? I would greatly appreciate it. Thx
Could you make anything video going over how you completed the build in trying to switch mine to gas and I want to see how it would be a huge help!
Nick, yes, that is no problem. I have not switched my cart over to the Torque Convert type of clutch yet, but I can show you exactly how I did this part, and you can just substitute the better clutch (not this centrifugal type... been through two of them already.) Thanks, and I should have that up by tomorrow night.
Hi there awesome build I love it..your build is the first I saw with forward and reverse. I have this old ez-go golf cart I’m looking to do the same but need a little more details. Could you make a video explaining how you did it. Please and thank you
What did you do to make that chain tensioner? Where to buy the roller? Thanks
Did you make the mounting plate to rear drive
I'm looking to do the same thing with my 1988 club car DS. I bought the same engine but it's the 440. I also bought the engine plate as well. Do I need to put a tension so the engine goes with the golf kart ?
Ray, yes, a tension idler for the chain-drive is important. Otherwise, when you are going fast, the chain can slip on the clutch sprocket.
What are your sprocket sizes?
What is your top speed?
Top speed is fairly low... I'd say about 10MPH. I'll check those sprocket sizes for you tomorrow. Thanks!
So no issues with the skinnier tires on there? I like the look of those a lot better and I'm in need of tires on mine.
No issues at all... here is the deal: at first I thought that by switching over to the more narrow tires, I would loose traction. Not so. In fact what happens is, the narrow tire actually puts more pounds-per-square-inch on the ground, and works well. The fat flotation-type golf cart tires are just easier on the turf, but really don't give you any better traction.
I figured the trailer tires would tear up the yard a little more since they're narrow like go-kart tires.
How did you get the reverse to work? Looks like you added something to switch the drive front to reverse.

What are the back wheels and tires from? Would there be any drawback to running those on all four corners? I like the way they look.
Chris, they are standard 4 on 4 (bolt pattern) rims and tires from Amazon, that normally go on small utility trailers. I have them front and back now, because I am trying to create an old Ford Model T looking rig.

Great set up. Have you checked MPH yet to see what it does?
Flat-out, about 20MPH. However, you can easily change the sprocket ratios to get whatever you want/need. It was a super easy conversion, and I have had zero issues so far.
Ok. Great thanks for the info!
Where did you find a sprocket to fit the splined shaft?
Chad, what I did was carefully grind down the splines with a hand-held
angle grinder, as I had somebody slowly rotate one of the back tires by
hand. As the splined shaft rotates, it is easy to take off each
"spline" and make a smooth 1/2" shaft. I then used a standard 1/2"
bore sprocket, and used JB Weld and the set screws to secure it. Works
great... no problems at all.
Victorian Machines nice job. I'm working on my ezgo conversion and i grinded the input shaft to 3/4in and will put a jackshaft on it.
Excellent! That is the way to do it!
Vmax?
Centrifugal clutch were dis you order that ?
How did you put Reverse on it?
Jonathan, I put a go kart transmission in it. It is the small aluminum mech that sits between the engine and the rear axle. There is a short #35 chain from the engine clutch to the transmission, and then a separate #35 chain back to the sprocket gear on the transaxle. The forward/reverse control lever uses two cables, and I mounted it on the driver's side, right on the front of the seat box-frame. Here is a link to the eBay auction for the transmission: www.ebay.com/itm/181890531869?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Victorian Machines here's a quick video I threw together with a few pictures of my conversion. Shows how the torque converter setup works with the same transmission you have. I made a slanted motor plate so it would sit nicely behind the engine, this way the belt reaches. ua-cam.com/video/CQX3Kg5pcpU/v-deo.html
nice video thank you.
Thanks Ron, it is a work-in-process. I am in the process of changing the centrifugal clutch over to a torque convert type. They are smoother, and you can vary the speed over a wider range.
Can you e mail me the parts were you got them I like your engine set up.. best video I seen . thanks .
Juan, thanks and yes, let me pull together some links of exactly where to find the parts as cheaply as possible. I was supposed to shoot a more detailed video of the mods, but just haven't had the time since I am moving.
can it reverts
Yes, it has reverse. It is controlled with a three position shifter... Forward, Neutral, and Reverse.
Scalded Dog!
Yeah you said a scalded dog. That engine was maxed out and you were only doing like 2 miles an hour at best. More like. runs like a dead dog. And is that a lawnmower transmission ahead of that easy go rear ended??? The easy go rearend is like a 12 to 1 ratio with that lawnmower transmission ahead of it you sacrificed every amount of speed you could ever get. I don’t understand. Sorry.
Donald... it's was a joke. It was just a hack to get the old girl even rolling again. LoL!
Yeah I missed that.
Scalded dog? I've seen new born puppies move faster than that..
Please kill the music so we can hear you
