[R1 Buggy]

Well as of this weekend I have
torn down my R1 from the frame and swing arm
removed the rear axle with diff and reversed to align sprocket in the center of cart as it was to far right on the passengers side
swapped the hubs with drums as the brake line brackets and levers were backwards once axle was reversed
also was able to flux core wire weld(crappy jobfirst time welder) the adapter plate(steel) to the spline coupler(steel) so that the sprocket can turn the trans axle

Next I will be figuring out how to jack this heavy huge motor up into the golf cart and mount it.
Previously ive already remove the rusted cage where the batteries used to sit and I will copy it and make a new one with steel rebar
I know this trans will not be able to handle this motor torque and speed and the gearing will be way off and it will be high revs with low speed but I don't have a four wheeler rear axle yet and until I find one if I can make this work then I will slowly cruise with it for now until I tear it up or find an axle which ever comes first.
If any of you out there have any tips and tricks on making this easier or more simple then by all means please comment. This is my first golf cart build and I am a newby so don't take it too hard on me. I just want a loud, fast, off road cart so can you blame me for trying???
I have seen several youtube videos of some taking the gearing case out and welding the two axles together with spider gears and bearings in the ends of each axle. Has anyone here done this? I'm considering it as an option but don't know where to start as far as getting parts are concerned.
Thanks everyone for any and all assistance!

There are a few things you need to consider here.

height of engine, has to fit under seat, ground clearance.

Using a chain or belt drive, The engine and rear end has to move as ONE. Going to need a swing arm of some sort!

Since your going to use the M/C trans, you will want the largest sprocket you can fit on the engine/trans and smallest gear on the rear end. The gear you have currently on the rear is going to produce a very slow cart!
I once used a GSXR engine, even though it was a 6 speed. 6th gear was still an under drive! Less then a 1 to 1

Depending on the final drive ratio of the trans and max RPM of the engine this set up will still only put you in the 30's MPH. Mostly because of the use of the stock rear end ratio around 12 to 1

The issue you will run into is the engine will not except a very large sprocket ( clearance issues ) and the smallest gear you can put on the rear end will bind and throw chains. That's why you will see most have some sort of a jack shaft set-up to increase the RPM's at the rear sprocket.

The easiest way to achieve your goal is to use a live axle to get rid of the 12 to 1 axle! But even then, (depending on what you want for top end) you may need a jack shaft.
If you get it geared for top end, Then you will need to get it STOPPED !! stock brakes will not do it.

Just my 2cents worth from my experience.

good luck, keep us informed

Thanks so much @Gearhead1956
I was afraid of that slowness you are talking about. I noticed once I welded the adapter plate to the coupler and put it on and began to spin it by hand the sprocket turns several revolutions before the hubs even begin to move and turn a half a turn. So I understand what you are saying. I don't want to sound stupid but being I've never messed with mechanics like this I just don't know what a jack shaft is nor where the best place to get one(bang for your buck). I will google it and research what one is... Looks as though its a shaft between two bearings one on each end which are mounted in some way like pillow blocks and are mounted to the rear end or frame. so im guessing the jackshaft needs to be between the motor gear and the rear axle to provide my small 13tooth gearing a chance to increase to 15-20tooth gearing? and then turn the rear from that larger sprocket. So if you have any good places or websites to visit for jackshafts please be sure and let me know. I will work on finding a live axle because this spicer stock trans just seems like a waist of time the more I look into trying to make it work. Maybe I can list it for sale and use the money to buy the jackshaft or live axle although ill probably need to add a lil more money to it.
thanks again so much for all the advice!

You should start by going to the big block talk on this forum and do some reading on bike swaps.
This is not as easy as it seems. Lots of fab and engineering work is needed.
Many have tried and most end up with a cart that makes a lot of noise with a big engine and go's very slow!

The only reason to use a cart rear end is to have reverse, and yours does not. you would need a 4 stroke rear end with reverse built in.

A jack shaft in this application, is not something you would buy. But something you would have to build. Yes, its used to change the gear ratio.
The math in itself gets complicated!
Engine rpm's, final drive ratio of trans. then the gearing, trans gear to 1st gear on Jack shaft to 2nd gear on jack shaft to gear on rear end thru 12 to 1 rear end then tire size!

Wow, yea so if im looking at jack shaft kits like this one then im wasting time?
Its for a 4 stroke kart

Building my own jackshaft doesn't sound impossible but very close to it :D

I will go to BIG Block talk and find the closest project comparing to mine and try to emulate whatever that person did.

I knew this wouldn't be easy but I am willing to put in the effort...
