R1 Powered TXT EZ-GO

[R1 Buggy]

Hello everyone!

Names Robert and I am a Hobart service technician who works on kitchen equipment. Current project im fixated on trying to get rolling is a 2004 yzf-R1 motorcycle engine to a 1999 txt ez-go rolling chasis(originally electric). It currently still has the stock rear end spicer trans and I've been told by several to get rid of it and fabricate a live axle or 4stroke drive and driven assembly to the rear. It currently has some leaf springs on it raising it about 3-5" I believe and the tires need to replaced with something nice and knobby for off-roading. I live in myrtle beach sc and golf carts are everywhere and we can drive them anywhere so long as we are not on major hwys.

Before I consider my options just know I will be researching this section of the forum and trying to find any projects similar to mine that were successful and emulating there progress...
option 1
If anyone knows of a place to buy a live axle kit for an ezgo or for something else that matches closely to the ezgo's then please let me know where.
option 2
Or if any of you know where to buy a drive and driven 4stroke axle assembly that would have reverse I'd be interested in checking those out too for pricing.
option 3
I saw a video on youtube of a guy who took the spicer stock trans out from between the driver and passenger side axles and then used spider gears with bearings and some welding to put the two axles together with a sprocket in the middle of the gears. Has anyone done this or know of a thread that shows this?

I only need the cart to do around 40mph normally with a top speed of 50-60 if possible. I've been told by Gearhead1956 I will need a jackshaft in my application but everywhere I look online they all seem to be for gokarts or motorized bicycles and im pretty sure they couldn't handle the torque.
Gearhead says I will need to build my own jackshaft.
Does anyone have a thread or youtube video on doing that?

So at this time the motor is off the motorcycle frame and sitting on a roller.
The cart rear is removed as I was in the process of reversing the axles so the spline could be centered as stock it sits too much to the passengers side. I swapped the drums so the brakes would match and still be used with the brake lines as they are in decent condition but I've been told I will need to rid of those too if I plan to actually stop. So if anybody here needs a stock txt rear axle complete with drum brakes I figured I post here first for sale before facebook, craigslist, ebay, etc... I will post as many photos of it as[/U] possible this evening when I get home from work.

Let me know if your interested and we can talk pricing I wont be asking much because I know I don't really need it and shouldn't use it.

Ok guys I just watched this youtube video linked above about how to build a jackshaft and this guy is saying its easy. He said to just find an old go kart and use the hubs to make a jackshaft out of them as they have bearings already and they are pretty solid with bolt patterns to mount to whatever you need. so I was looking around and somebody else stated you can just go to bmikarts.com and buy hubs with bearings already in them for like 10 bucks. so looks like I can make my own jackshaft after all for less than 30-50 bucks and some fabrication. I'm excited.
Anyone here ever made a jackshaft out of wheel hubs? I'm going to try. I'll post up what my progress is. Seems like a genius idea!!!

Many ways to get this done. The stock Golf Cart 4 stroke engine shifter rear axle probably won't last long behind the R1, try for an ATV axle from at least a 500 CC, you still won't have reverse though. Another way is use a Honda Prelude trans axle, look at the bike engine dune buggies, this will get you reverse plus an infinite choice of gear ratios by having the 5 speed plus reverse in the Honda trans and the bike trans. Another way is to have a starter motor to run the cart in reverse, you can search that and it will show up. I ran a swing arm that I built with Coilovers and a Mini Sprint car rear axle using all Mini Sprint hardware, finally using a 13 tooth front and a 60 tooth rear to keep it from bogging on launch,,, but that was with 10 inch slicks. Build on!! Spend Money!! but please finish the cart. I must stress!!! be very aware that you are powering a vehicle with 100 times more Horse Power than it was ever intended to have, think about your own safety and the safety of anyone with or around you while operating it. Mine was dangerously fast but I had very good brakes, harnesses, full cage, window net. Think safety first before you go fast. I'm not a preacher, I like to build fast stuff too, look at my builds, I have several on here.

Thanks so much rifter for all the advice!you are the first to recommend using a Honda prelude transaxle. It sounds a little more difficult to fabricate to the machine versus the ATV live axle but to have a reverse would be nice plus we have several junkyards in my area where I can most likely find one from my wrecked Honda prelude. Why is it a Honda prelude transaxle works for the easy go application that I want to achieve? What's special about it that makes it work or can any Honda transaxle be used ? In all honesty he I'm very anxious to try and get this on the road but as you said safety should always come first in all in all it seems that the ATV axle option seems the "easiest "my only problem is I'm having trouble just finding a rolling chassis for sale because I would like to have all of the brakes and complete axle assembly that come with it as well as the swingarm so that the engine and axle can be is o my only problem is I'm having trouble just finding a rolling chassis for sale because I would like to have all of the brakes and complete axle assembly that come with it as well as the swingarm so that the engine and axle can be as one.as soon as I get off work I'll be checking out your page and in looking at the projects you have completed to get some ideas again thanks so much for the help and I'm grateful for the advice have a great day

Stupid autocorrect talk to text��

You should not need a jackshaft, I had a ex500 hooked to a G2G rear and it was geared perfect, maybe a little fast, remember you have 5-6 gears of the bike engine.

What you really need to do is change the front axle, you will have dangerous bump steer that will have it walking worse than a wheat truck and and you need upgraded brakes as your brakes will be worse than said wheat truck.

It is really recommend to go with a at style swingarm as it can take the power and brakes. I've never heard of the Honda prelude transaxle modification but that sounds like the ticket, leave the bike in 1:1 gear or one gear under, use the bike clutch, and shift with the Honda transmission.

Thanks for the advice cfherrman
But What is a G2G Rear? Im assuming the ex500 is a atv
As far as the front axles concerned I understand all braking and steering needs upgrading as it will be driving faster then intended hence why I need an atv chassis to apply the suspension and disc braking to the front and rear.

The car transaxle mod sounds great(heavy but great) but honestly I haven't seen any videos of people riding around with that application. most are on live axles which were from racing go karts or atv's and the occasional 4stroke transaxle. But if I could see something like this already applied maybe it would make more sense. I searched and searched but all I could find were photos of prelude transaxles which look complicated to even understand how I would get the sprocket to turn it. so I will keep looking but im currently searching around on BMIKARTS.COM and it looks fairly simple to just replace the stock electric transaxle with a ordered chromoly live axle and get all the extras like pillow blocks, collars, hubs, etc. kind of looking to see if they just have a kit or assembly already set up in 1" or more configuration.

This video by T-man really is pushing me in that direction. that way I can go ahead and get it on the road driving and upgrade everything else slowly as it becomes available.

Here is the spicer trans axle currently on the txt ex-go. I have removed it and flipped it to line the spline up with the middle and swapped the hubs as the brake levers were reversed when I reversed the axle.
I will swap it back as it was only 8 bolts from the frame and 4 on each hub to do this as soon as somebody tells me they want to purchase it. I have no use for it... Right?

G2g is a stupid autocorrect version of 'g2', as in yahama g2 golf cart.

Prelude, Civic have the input shaft on the left while most others have it on the right, you can adapt the bike engine mounting and install a sprocket and outer support bearing on the Prelude input shaft, you will also have independent suspension on the rear, and it's easy to shorten the axles and change the steering assembly to a fixed steer.
