Sneaky build

[sneakysilverH3]

Well yes i am new, my name is John. I bought a go kart awhile back (dont kbow the name) i have installed a predator engine and new cluth all from northern. I am getting a list of supplies fron bmikarts to do a live axle swap. I do believe i have the right parts to order but i dont understand how the sprocet will be held the axle. I know welding is an option but dont wanna waste an axle. Also what brake system do yall think is best for the money i dont plan on racing. I am mainly going to be off road with this so i know disc is best but would drum be enough? I will post pics and go more into detail about what all i want to do to the kart. Also will put my parts list and maybe yall can double check it for me thanks!

Ok for parts to go from dead axle to live axle
Axle bearings
Liveaxle
Bearing hangers
Bearing flanges
New wheels and tires
Sprocket
Sprocket hub
And a brake system
Are there any parts missing?

Get pillow blocks in stead of the flange/hanger/bearing's. You might be able to save some money by just getting some keyed shaft in stead of a marketed "axle".

Not all sprockets have a separate hub, some are integral. And on that note, if you get a separated one, make sure you dont get the sprocket to hot welding it or it will warp. TIG it if you can or get some one to for you (the best way, but obviously mig will do).

Make sure you gearing ratio is correct before you go buy a bunch of sprockets. account for tire size and clutch tooth count asawell.

I'm not ordering parts yet and I was plan on getting a sprocket and hub that bolt together and has a set screw to hold it, would that work also I still need to pick out my tires I want 12" knobby

Also I plan on using centrifugal clutch for now. So looking at 12 T clutch and 60T sprocket so I can get a 5:1 ratio (if I'm correct) I also looked into the bearing pillows, what makes them different? I honestly don't know. Only thing I feel like imma have a hard time with is setting up my brake system

Brakes aren't too difficult (as I have just discovered, thanks to some advice from Fabroman).

If you take a look at my build thread "Our Project", there is a recent photo where you can see my brakes and axle.

I bought a caliper, master cyl and disc which normally goes on a Chinese dirt bike. The lot was $65 AU, I'm sure you would be able to buy the same thing or similar there.

You will need a carrier to hold the disc on the axle.

There is a little bit of mucking around to make a bracket to secure the caliper but it's not hard.

Pillow blocks are much more durable and they can handle much more abuse. Plus no welding for the "bracket", they just bolt on.

Post a pic of the vehicle.

Here is the kart sat for 5 years and have been doing stuff here and there but finally running great and ready to make it better

Well I have a round tubing frame. And I was gonna weld on square tubing to give a bit of a rake and some clearance for bigger tires

I want 12" knobby

Personally, I'd go for 15s... but, that's just me

looking at 12 T clutch and 60T sprocket so I can get a 5:1 ratio

Correct but, that may be pushing it a little bit

T-Man made a vid about a year ago (can't find it right now) showing an ATV brake setup he bought for $40

 

[Poboy kartman]

Are those 145/170-6 tires? I can't get a lot of detail from your pics, but I think that may be a Manco. Is there a "Masters of Motion" sticker on it?

Haha wow I didn't realize I put 12 but yes either 14 or 15s I have 14s now now for the ratio Idk what would be a good set up honestly I want torque but also want top speed. I'll start doing more research into the atv brakes

[OzFab]

now for the ratio Idk what would be a good set up honestly I want torque but also want top speed.

Pick one, otherwise, you get a happy medium; 6:1 is a good starting point. 5:1 on 15s will give you a good top speed but, acceleration will be lousy...

Ok I'll start with a 6:1 mainly because that's what I have now but the acceleration isn't that noticeable because of spinning the one drive wheel. Just need a sprocket hub to mount it to the live axle right?

Correct, it's on the parts list

John I just bought almost the same parts list from BMI. Check their clearance page before you order. They have the bearing hangers and bearings cheap. and used? wheels and tires. Also they have a bearing kit that puts them all together it is 18 bucks and it is 34 elsewhere.
I bought the unihub sprocket hub (14$) and it seemed bent when I questioned them they suggested getting their aluminum hub. It is 22$. They also send me a broken clutch having trouble returning it! They do have great pricing though.
Search their site thoroully they have a ton of stuff. I tried to order every thing at once and ended up making three orders NO FREE SHIPPING.

Have you stopped to wonder why? As you said in another thread

you get what you pay for.

 

[chancer]

Yep. They sell cheap parts. I am learning that the hard way. That is why I mentioned the Hilliard clutch by name. They do have good pricing, so if you know exactly what name brand part you want I think they will probably have the best price. As for the generic parts, bearings, axles etc yeah probably made in China junk. I also posted in another thread "I am a cheapskate" LOL

 

[OzFab]

I also posted in another thread "I am a cheapskate" LOL

Most of us will shop around to save a few bucks if we can, as I do but, I don't compromise on quality; I'd rather pay the few extra dollars for Japanese bearings & know they'll last than cheap out & buy Chinese & have the fear that they'll collapse at the worst possible time...

I have looked into there parts and compared them to others, I don't plan on buying all my parts from there, I have decided to get pillow block bearing. Pretty much just ordering tires rims and axle from them now

Correct, it's on the parts list

What are you confused about? My go kart as it sits right now has a 12 tooth clutch and 72 sprocket so I have a 6:1 right? It's single wheel drive Idk if that changes things
