How to make your Sled Motor haul the mail in your EZGO

KoogarKiller · 03-10-2011, 11:19 AM

So Ive seen it time and time again... People swap a twin 2 stroke motor into an Ezgo 4 stroke cart and it works.. but the cart doesnt get the acceleration and top speed it should...

So here is the solution:

A Polaris ATV Driven Clutch!

The splines line up with the ezgo rear end... Just slide it on, bolt it up and off you go.

This made my cart twice as fast out of the hole and about 10 MPH faster on top. I am running a secondary clutch off of a 07 Sportsman 800 made by Team Industries.... However just about any of the Polaris ATVs will work. (I talked to the tech guru at Team and he said the 800 clutch is the best one to use if I could find one ($80 on Fleabay)
... There are lots of Ranger, RZR, 500, 700, 400 clutches out there.

It is a roller clutch that is fully tunable...

My motor is a yamaha 440 Fan Cooled that makes about 55hp

The cart flys now! So far I have hit 50mph and am still dialing it in. My rear end is 10.5:1 ratio.

Hope this helps some of you out that are building sled powered carts....

I'm glad someone posted this. I asked a few months ago if anyone knew if another clutch would work on the ezgo and no one seemed to know the answer. Now only if we could find one to fit the engines,hmmmm

Hmm sounds like I need to keep my Yamaha 540 twin and do a little chopping up?

If you have a SRV 540 fan find a PSI pipe for it, night and day you will be amazed. Run the high altitude kit in the 540 clutch.

hey i have a ezgo from the 80s i put a suzuki 340 sled motor in and it tops out at 20 i have noticed that all the carts ive seen have a different rear axel mine looks like one out of a truck just with a pulley on the pinion shaft and i checked the gear ratio in 6-1

I just wanted to say thanks. This thread helped me a lot. I got a Polaris xp 850 ATF clutch for 61$ to my door. And it bolted on THANKS IT HAS. LESS THAN 10 hrs run time SCORE

what width belt do you guys run with the polaris secondary clutch ,the belt from skidoo seems awful wide

I checked out the sportsman 800 on ebay and they all look keyed instead of spline. Am i missing something?

The one I bought was splined and bolted right on my gas ezgo rear end
