r/gokarts

A while ago I was looking for a yerf dog 3203 axle with snap ring grooves but couldn’t find any, so I just decided to order a fully keyed 45 inch axle, (original is 39 - 1/2) and then I measured each snap ring groove made 2 lines for each groove with a 1/8 width and moved them down by 5-1/2, I did this for all 7 grooves, then I used a 1/8 thick angle grinder disc and I carefully made the grooves and filed/deburred them, they all fit nicely and are surprisingly straight. But I’m just curious, dose this compromise the strength of the new axle?

I’m trying to mount this quad suspension to a go-kart. I want the main kart frame to sit roughly 12 inches above the ground, with the wheels/tire centers sitting below the frame. I’m trying to figure out the best way to connect the suspension to the kart frame using the existing suspension and scrap steel. (P.S Don’t talk about the rust I will sand and paint it later.)

wheel is wobbling, I don’t think it’s the axle since I just put it on, well at least I hope it’s not. I’m thinking it’s a bent rim since the tires I put on are pretty old and rusty what are your thoughts?

Found this on Facebook marketplace. I’m trading a minibike and some Motorola radios and some other radio stuff I don’t need for it. It also runs perfectly

Restoring an old heavily modified cart (I believe it was a Manco but it's been chopped up and extended) with a predator 412. Terrifyingly fast and the brakes need work, so I figured I'd see if it's possible to convert it to hydro but I'm running into a space issue. I can't see a good way to mount a master cylinder in front of the pedal since there's only a couple inches of frame to work with.

I thought of moving the pedal back but then it would be a little too close to the steering, plus I don't want to reduce leg room. Another option is extending the part of the pedal below the frame and mounting the cylinder behind and underneath, but I'd be worried it would get ripped off, which would obviously be not so great.

If anyone has done this before and has any ideas/tips, please let me know! Worst case scenario if it can't be done I'll keep it cable and just get a beefy caliper setup.

Recently picked up this vintage go kart on fb marketplace. The guy I bought it from said it’s from the 60s and has been sitting in a bush hidden from view for years. I plan on either restoring the motor if it’s original, or swapping it with an electric motor from an e-bike!

So my son’s go kart keeps leaking gas out of the carburetor and gets flooded. I thought the gas tank was building up pressure too much and I installed a pressure relief valve in and still having gas come out the carburetor. I don’t know what else to do.

Do yall think my engine is running good or lean? Plug has only been run for about an hour.

It looks pretty aligned to me, I have no clue why it’s shredding so much.

Love the leaning I'm doing with this go kart. Not the best weld but learning.

I love the torque converter compared to the clutch

I did this EZ-GO electric-to-gas conversion as a hobby build and for the wife and kids to enjoy. But we moved to the mountains immediately after I finished the build and bought a Polaris Ranger so this thing has been sitting (winterized, but still). Just wondering where you all think I should price it and maybe some suggestions for things to include/exclude in the listing… here are the bullet points.

Electric-to-gas golf cart conversion with new (about 5 hours) predator 420cc engine, electric start, heavy-duty drivetrain, ~5X the horsepower as when it was electric.

Brand new tires
New steering rack

New hubs
New backing plates and brake assy/pads
New leaf spring bushings, bolts and hardware
1” jackshaft with 1/4” keyway
Heavy duty pillow block
50 series chain
Brand new 3,000lb winch
LED light bar and 2 minis
Brand new 110 amp hour marine battery
Parallel charging coils (3 amps)
Voltage rectifier
Go Power Sports performance intake

Oil drain hose
Governor removed
6:1 differential (the fastest gearing)
Mini bike exhaust
Folding rear seat/truck bed

All seats are brand new and have zero wear or tears. New aluminum floor pan. Horse stall mat for floor.

Manco magnum express wheels won’t come off even after using a hammer and wooden 2x4 from the back… could use some tips if anyone has a good method or tool I could pick up for this. The axle is covered in these collar spacers behind the wheel as well.

I have a barn find kart, looks to be a serious racing machine for oval track, maybe? Can anyone tell me more about what I’ve got here? I have all of the parts, I was wanting to rebuild it into a “milder” version of itself for more all-terrain riding, or am I starting with something inappropriate for that? I don’t mind sinking a few bucks into it.

Any option other than re mounting the engine?

I don’t think this really belongs in this group anymore where else should I post it
