This is good information. I am wanting to build a small boat and I need a reverse. I am considering a 2 cylinder engine for smoothness. Singles just vibrate so much.
I did a similar project on a ez go cart. And I found that you have too line the primary and driven clutch back plates with each other to get the belt to run even thru the whole rpm range. Not the centers. I did it the same way and noticed that the belt was running at a slight angle when the motor was revving. Yours might not do that. But after shifting the motor over to line the back of the clutches up it ran true throughout the whole rpm range. Great job bro! You made it look a lot easier than mine went. Lol
what all extra did you have to buy besides the motor for this to work? I can't seem to find any type of parts list anywhere from these builds people have done. Thanks!!
The comment that says to line up the back of the pulleys rather then the centre is right. The outside pulls in and out as needed. The proper primary has a spring inside holding sides apart. Does yours and is it strong enough?
Was the original engine 2 stroke or 4 stroke? I've got a golf cart I'm doing a budget build on for my father inlaw. It's a 89 ez go 2 stroke gas, the engine was shot so I picked up a predator 212. I'm using the oem driven clutch, what drive clutch do you reccomend? P.s. I still have the oem driver
I am doing a similar conversion. I have a yamaha g9 cart and I'm installing a Honda g160 motor and I need a belt. what size did you use and where did you get it?
are there any videos on how exactly to install a comet style drive pulley onto the 3/4" shaft of a 212cc predator motor, the pulley is tapered & having trouble finding any adapters that will work, thank you.
That's awesome! Just seeing this frame it brings back such memories! Back when I was 14 I had a almost brand new Yamaha golf cart. Those clutches have pucks for weight. You can easily remove some weight off each one to increase your stall speed of the clutch. JUST make sure you remove the same amount off each one. A digital scale works the best for accuracy! Hope that helps?
You know your stuff man! Just watched all three videos. I am in a similar situation. I keep going back and forth between the 6.5 hp or 13/14 electric engine...I'd like to do the 6.5, plus I believe I have most of the original golf cart parts; clutches, etc. I do have the original golf cart engine, but was told it caught fire, carb is off...just need the time to look. Enjoyed your videos here and look forward to your next ones. Also worried about the end of this, how's the clutch coming along with idling?
Well, i just uploaded a new vid where i tuned the clutch. Spoiler alert, I’ve since then bought a comet 780, which is specifically designed for this application. As far as using an engine with e start, that would be way easier. But from what i read, most of them only have a 3 amp charging system, which is ok to maintain the battery and MAYBE run a few lights. Personally, I’m planning on using a golf cart starter/generator, which will not only give me e start but charge the battery at 15 amps for front and rear lights, as well as a radio with a speaker or two.
Great video, you can also disconnect the wire to that kill switch and run it to a more easily accessible toggle on the dash. Be a easy way to shut it down.
That sounds awesome! I have a f/n/r transaxle from a 4 stroke ezgo in mine, maybe you could do a similar swap depending on how your current transaxle is designed.
I had to install a transmission to add reverse and neutral. Turned down the idle to a low rpm in order to shift from forward to neutral and reverse smoothly.
Currently have a 91 ezgo 2 stroke w low compression in thinking about swapping. Need it to be capable of hauling four of us at the camp ground. Is your 212 suitable or should I spend money for the 420
I'm new at this. First I want to convert a harley three wheeled golf cart to four. Is there a place to buy the suspension for the two wheels and steering for the front?
Depends on your skill level and access to tools. You could get a 4 wheeled parts cart and graft the front end on, you could use go kart parts like a arms and steering and all that jazz, you could find an old four wheeler and use parts from that. It’s a lot of fabrication. Most people will tell you just to sell it and buy a 4 wheeled cart, but if you can get donor parts for cheap it would be worth it.
Honestly i just got the longest belt i could find that was the right width, and mounted the engine where it reached. The belt i used is a dayco hp2028 which is 56” around and 1.19” wide
think you need to align the motor side to that side of the rear pulley , those sides are mounted solid the other sides move in and out wat you could do to have the clutch engage at a higher rpm is change the springs in the clutch part of it (thats the part that causes the engagement and slippage the belt and pulley just transfer the power ) ua-cam.com/video/-8ymMBnfR84/v-deo.html&ab_channel=KartFab as for checking if the belt hits the frame , just tape a strip of paper to go under the belt and over the frame somewat tight (no tape over the part you suspect the belt to hit ) and take it for a drive , if the paper is blackened or torn off at the end of the trip the belt is hitting the frame if the belt is trowwing pieces of rubber off you might want to tension it a bit more , it seems awefully loose the way you mounted it
I don’t remember the size, but it’s in one of my other videos i believe. It was the longest dayco power sports belt i could get that’s the correct width.
I have a 20 hp vanguard v-twin on my 1993 ezgo marathon . does your cart start when you hit the gas or do you have to turn it over with the key and leave it in idle???
Hi the way my ezgo is set up from the factory is the belt isn't tight! So you half to give it some gas an it makes the belt right and goes! I think you putting the belt all the way tight is the problem.
I got an adapter that’s 3/4” inside and 1” tapered outside. I didn’t make the shaft any longer. A narrower belt may keep it from engaging too early, but both clutches are designed for this width so i wouldn’t get the full gear ratios.
@@BackRoadBomber Thanks for the reply. I am building the almost identical cart to what I see you have. Right now I am running the torque converter to chain method but I want to try the direct belt method as in your video. How did that work out for you? Also, do you remember the brand and model of the drive clutch you installed and where you purchased it? Thank you.
@@2001gwmc the rear axle is from an ezgo so it would have forward and reverse, with the stock ezgo clutch. The drive clutch is a knock off replacement for the gas version of the g1, but I’ve since purchased a comet 780 as the drive clutch, since this one still engaged way too soon.
@@BackRoadBomber Thanks for communicating with me. I'm new at this. I'm an old guy (76) and just needed a project to keep me busy. Today I received a drive clutch from Amazon. The brand name is VEVOR. After taking the cover off it appears to be identical to the one in your video. I now understand about the 3/4" to 1" adapter. I have looked at them online. Do you use a key in the slot on the shaft or does compression/pressure old it tight on the shaft? Also, the bolt that came with the clutch is way too big so I guess I need to get a bolt the correct size and length for the predator engine. I have a 1996 Yamaha G14. I only have the frame (no body). I do have forward & reverse on the rear end. With the torque converter and chain set up I got 15 mph. That's fast enough for me but I wanted to try the direct belt set-up like in your video. Thanks for your help.
@@BackRoadBomber I received the tapered shaft adapter. It did not come with a "key". Does it require a key in the slot? It seems like it would take a special key that has a step-down to it (one size for the engine shaft stepped down to a smaller size for the adapter).
Well the rear axle is from an ezgo txt gas model, it had a 19 spline input shaft. I bought a 19 spline motor couple meant for electric models and it fit perfectly, then i just had to bore out a sprocket to the same size and welded it on
The cart was originally electric. I swapped the rear axle from a 4 stroke gas ezgo, and as soon as i make the linkage and hook it up, it will have reverse
Watch the bolt holding the clutch on....not running true...loose bolt?...bent crankshaft?.... you can remove some weights from inside the clutch so it don't engage so soon.....ski do clutch...you would have to add weights.
I didn’t yet lol i have to manually flip the lever on the axle. I’m hoping to find a column shift mechanism from the junkyard and use a heavy duty cable.
This also makes a great legalized no licence starter car even with a 7 horsepower lawn mower engine cannot go any faster between 30 to 40mph estimate. Do not also forget the key ignition as an option so it looks like a wannabe car.

BACK PLATES aok < GREAT to know
Back plates are the plates that don't move.

How did you mount the tampered clutch adapter to the clutch. I have 3/4" shaft adapter
Do you put a pulley on the existing rear axle? can you just buy that special pulley (centrifical I assume) .... thanks much !! GD Tractor
What kind of clutch and belt are you using?
Also, how did you make the shaft longer on the Predator 212?
I am doing a similar conversion. I have a yamaha g9 cart and I'm installing a Honda g160 motor and I need a belt. what size did you use and where did you get it?
Great job but where did you get the torque converter at .
Do you have an link to find the clutch?
are there any videos on how exactly to install a comet style drive pulley onto the 3/4" shaft of a 212cc predator motor, the pulley is tapered & having trouble finding any adapters that will work, thank you.

Instablaster.
Predator 420, works great.
I was told that you can remove some springs from clutch and it won't take off right away.
Where are you located and do you do it for customers or just a personal project
Where did you get the clutch??
Where can I find that clutch?

What torque converter did you use
Great video, you can also disconnect the wire to that kill switch and run it to a more easily accessible toggle on the dash. Be a easy way to shut it down.
Was the spider measuring something?
Wanted to let you know there is an idle screw on the back side of the carburetor idle it down and you can shift it in gear
I did a 720cc vtwin subaru engine that runs on propane in an 89 ezgo. Only thing I need to work on is adding reverse gear.
That sounds awesome! I have a f/n/r transaxle from a 4 stroke ezgo in mine, maybe you could do a similar swap depending on how your current transaxle is designed.

Where’d you get the engine mount plate? I am doing the same engine swap on my 1983 Yamaha G1. Great video by the way
They sell them at harbor freight

The 70s and 80s 2 stroker rear ends are set up super different
How did you figure out what size belt to use I am installing a predator 420cc in my 01 ezgo and I need a longer belt
Honestly i just got the longest belt i could find that was the right width, and mounted the engine where it reached. The belt i used is a dayco hp2028 which is 56” around and 1.19” wide
either you have a crankcase bearing going or you don't have your clutch tight. check it
Hi where did you get the aftermarket clutch I've got a 212 predator engine
go power sports .com
think you need to align the motor side to that side of the rear pulley , those sides are mounted solid the other sides move in and out
wat you could do to have the clutch engage at a higher rpm is change the springs in the clutch part of it (thats the part that causes the engagement and slippage the belt and pulley just transfer the power )
ua-cam.com/video/-8ymMBnfR84/v-deo.html&ab_channel=KartFab
as for checking if the belt hits the frame , just tape a strip of paper to go under the belt and over the frame somewat tight (no tape over the part you suspect the belt to hit ) and take it for a drive , if the paper is blackened or torn off at the end of the trip the belt is hitting the frame if the belt is trowwing pieces of rubber off you might want to tension it a bit more , it seems awefully loose the way you mounted it
Did you had to modify the shaft to install the stock clutch on the predator engine ?
Why do you put a space before the question mark?
Fyi, in the future. line up your belts with the stationary side of the clutch on both front and back. Takes the guest work out.
The stationary sides are opposite. The inside (closest to engine) is stationary on the drive clutch, the outside is stationary on the driven
Where you get the belt? I need one that big but can't find it.
Ditto
how did you get the tapered clutch to fit on a strait shaft
Have a friend with a machine shop like I did we made up a tapered bushing
Hey sir what belt r u running I need some numbers and a linth if u don’t mind
I don’t remember the size, but it’s in one of my other videos i believe. It was the longest dayco power sports belt i could get that’s the correct width.
I have a 20 hp vanguard v-twin on my 1993 ezgo marathon . does your cart start when you hit the gas or do you have to turn it over with the key and leave it in idle???
Right now it’s pull start only. Once the weather breaks I’ll be swapping in an electric start engine abs. Making it key start.
Do you have a video series on that build cuz I am doing the exact same thing
If you have a 93 when you mash the gas pedal I think it's called a stop and go
A little longer belt or just move the engine back a little. This will slow down drive belt engagement.
Thank you! I will do that when i pull it out of storage and start working on it again.
Hi the way my ezgo is set up from the factory is the belt isn't tight!
So you half to give it some gas an it makes the belt right and goes!
I think you putting the belt all the way tight is the problem.
Thank you! I am beginning to realize that, i haven’t worked on the the thing in a few years but i still have it and it’s still unfinished lol
Where did you get the primary clutch?
??
What transaxle is that it doesn't look like a factory g1 transaxle
It’s from a 4 stroke ezgo workhorse
What is the part number to the belt? Thank you
022034123
Where did you purchase that drive clutch that fits a 3/4" shaft? Also, wouldn't a narrower belt also solve the problem?

Hello how did the clutch work out? We're and name were you got clutch and belt number appreciate if you can help me out
The primary clutch didn’t work well i ended up getting a comet 780 series and the belt is a dayco hp2028. I’ll make an update video soon.
How did you do the rear back sprocket
Well the rear axle is from an ezgo txt gas model, it had a 19 spline input shaft. I bought a 19 spline motor couple meant for electric models and it fit perfectly, then i just had to bore out a sprocket to the same size and welded it on
Where did u get the longer drive belt?!
It’s a dayco hp2028 power sports belt
Come on man , don't you have a set of stones🤣😅????? I think we've all done a test ride of regret. I wanna know more about this clutch though
was the clutch a straight shaft? not tapered? what size shaft?
It’s an aftermarket Yamaha g1 clutch, tapered shaft.
thanks.
@@BackRoadBomber so how did u get it to fit the 212cc predator i saw on ebay a billet aluminium sleeve to convert the shaft is that what u did
Lowering the idle should stop the clutch from engaging at idle
What kind of belt did you use
Dayco hp2028 powersports belt
This also will move forward n reverse?
Yes i put the f-n-r axle from an ezgo in it
What clutch are you running
This guy clearly doesn't want to answer questions but it looks like a knock off of a comet 44c
What kind of speed are you getting out of it now
At that point it was about 22mph. Since then I’ve changed some stuff, though.
@BackRoadBomber what did you change and did it change top speed?
does the reverse still work?
The cart was originally electric. I swapped the rear axle from a 4 stroke gas ezgo, and as soon as i make the linkage and hook it up, it will have reverse
Hey can u please tell ,e that belt size
It’s a dayco hp2028, it’s 56 inches long and 1.25 inches wide
What about reverse?
It has a rear axle from a four stroke ezgo in it, i just haven’t built the linkage to shift it yet.
Watch the bolt holding the clutch on....not running true...loose bolt?...bent crankshaft?.... you can remove some weights from inside the clutch so it don't engage so soon.....ski do clutch...you would have to add weights.
Hi, say my name is Chris and I want to do the same thing with my cart. I have some questions and would really appreciate it if we could talk.
Sure thing. It’s been three years the cart is very different now, but if i can help you i will.
I’ll bet those welds didn’t hold.
How do you got it to shift to forward to reverse
I didn’t yet lol i have to manually flip the lever on the axle. I’m hoping to find a column shift mechanism from the junkyard and use a heavy duty cable.
