$150 Offroad Go Kart Find!

In this video we resurrect a Firefox 620 go kart we are calling internet explorer. It has a 6hp Mitsubishi engine that had a gummed up carburetor and it only needed a rebuild to get running and driving. It's especially cool because it has a full suspension with front independent suspension. After we got it running we took it off road and had a lot of fun driving it around. We found this thing cheap on craigslist and plan on doing a full build with it in the future!

Sorry for no upload last week....we were all pretty busy over thanksgiving but now we have some awesome videos on deck. Stay tuned!

[@morpar318]

Hay Build Break Repeat will you guys should put in a predator 670 in that cart that would be sick.

[@danmackintosh6325]

If that TC is working properly (did sound a bit high-geared on take off) the next thing I reckon you should do is remove the governor from the Mitsi engine and make sure the exhaust isn't bent/restricted as it looks to be blowing directly on the frame tube.Other than these 0-buck mods I'd suggest replacing the chain/sprocket combo to gear down a bit and help it get "out the hole" better (plus that chain is haggard anyway lol). This and removing the governor should get a bit more out of it, and if you end up blowing the motor you were gonna swap it anyway right? might as well get your money's worth out of it first... Oh, one last thing is either replace the carb or make sure it's fully cleaned out, that might help power too. Thanks for sharing, I think you got a bargain.

[@gokartmasterjames8394]

The sprockets are definitely a speed issue, I think it goes from about an 8 to a 70 tooth, Should get like a 12 tooth lol

[@isaiahtaylor8887]

Build Break Repeat i have the same gokart but im putting on a 540cc kawasaki lawn mower engine

[@collinhetsler4746]

Love the videos man always happy when I see you’re posts

[@zukislumber]

this would be great for young new riders. Nice vid. Thanks.

[@rickburnout666]

It needs a 670 in it

[@Leek2x]

Video and music was soothing 😂😂 I enjoyed it

[@BuildBreakRepeat]

Leek 2x lol yeah my friend made it, link is in the description check it out!

[@sonicserveweb-marketing-me5303]

Hey, Thats amazing. Makes me want to buy a go kart 😲

[@colbybarbour9990]

did you get one?

[@j.w.3345]

I doubt you'll ever see this comment, anyhow....I just picked up this exact cart frame today. No engine but I'm putting on a Predator 301 or 420. For the life of me, I could NOT figure out what kind of kart it was. Mine had no markings. Thanks for solving that for me! J

[@Leek2x]

This was really cool

[@bawltelilyoung9801]

Leek 2x can i bye

[@gokartmasterjames8394]

I think most of the top speed issue has to deal with the gear ratio that’s on it.If you’re running it at 3600 rpm, it should run about 22mph.The gear ratio is like 8.75 I think.The sprockets on it are like 8 and 70.Mine’s also really slow, but it’s like the best thing I’ve driven for off-roading.Mine’s yellow, but I think they’re the same.I got mine a few weeks ago and had to clean the gas tank and the carb.The gas tank was a pain to get on and off.It doesn’t have a seat bottom yet but I’m going to bolt an old seat cushion on it hat I’m sitting on to drive it.Paid 250 for mine, needs new front tires, but it’s a Monster.Thinking about putting a 12 tooth sprocket on it,If it’s hitting 22 right now it should get close or over 30mph.

[@MarkSawatsky]

The front alignment is keeping it from accelerating. Looks like too much toe-in is acting like the brakes are on.

[@witosarlaw]

Mantap bang

[@darringoodbrand6603]

Wouldn't be driving it with the front wheels like that lol

[@therealcolinfreeman]

Wow someone else has the same go-kart as mine lol

[@christianlucatino1910]

I’d do 2 things with this 1 fix the CVT (torque converter) it seems to have an issue with something slipping either the belt or clutch portion seems to have an issue 2. Remove the governor That would give it way better top end and higher top speed I would swap the engine for a predator. Everyone does that I’d try something different. The engine seems to be pretty healthy. No knocks or ticks. It also seems to not have any blowby which means you’ve got good piston rings. I’d keep it if I were you

[@BuildBreakRepeat]

Christian Lucatino Cool, Thanks for the advice.

[@kylec.5462]

Wow 2 guys who build go karts all the time, but they probably need your advice.

[@stevendohm3399]

You should keep the original engine it has on it right now can clean it up a bit and see if you can get some performance for the engine

[@beans4gas]

Damn 150! Im in Oregon and something like this goes for 1500!

[@colbybarbour9990]

Put a 670 predator on it

[@BuildBreakRepeat]

Corey Lyscas Lol you guys are insane....It would be sick but the budget doesn’t really allow for it right now haha.

[@takerkanefan108]

reminds me of Rather Be Weldings mini buggy

[@BuildBreakRepeat]

takerkanefan108 Yeah kinda, his is sick, hopefully he gets it running good soon.

[@DrLove911]

Idk what city you looked in on Craigslist but it's hard to.believe

[@spikemandan]

have you checked the axle rod bearings? i noticed it still locked up and very poor acceleration

[@BuildBreakRepeat]

spikeman dan They are kinda tight, well look at replacing them.

[@spikemandan]

may as well see if its able to be restored take them off and set them in fresh oil for the night it just may do the trick better off saving money that way if that fails then yeah go ahead and get new ones only reason i say this is because it just a $150 go cart might as well keep it a cheap build your buddy spike ;)

[@BuildBreakRepeat]

spikeman dan Ok cool thanks

[@K.J.Ray421]

That's exactly what I was thinking. The tires stopped dead while it was on the jack at 9:30 and it also killed the engine. If it can't freewheel with no friction, then your axle is nearly locked up or brakes are stuck. And since you know the brakes aren't working atm, it must be axle bearings or the torque converter seizing.

[@staceystarling15]

Have same kart. How do i replace rear axle bearings on this. Def was the crusty axle bearings locking up n rear

[@deweys]

How do people find these karts for sub $200? Every kart posted in my area is near list price and covered in rust..

[@colbybarbour9990]

i don’t know what you mean, this lady gave me her sons old one after i fixed her deck! lol

[@skarekr0w3]

What calipers are those?

[@foulmouthgolf1449]

Do you guys live near Kansas City

[@ryan.b1861]

My predator 212 Boggs out and sometimes it shuts down I think it a fuel issue but the engine is almost completely new

[@BuildBreakRepeat]

There’s a low oil cut off switch on predators that will shut them off a lot if you still have it connected and drive it Offroad. If it normally drives fine but shuts off when you hit big bumps and stuff that’s probably your issue.

[@ryan.b1861]

Thanks it may have low oil because it runs a little ruff and hot thanks

[@lobdaboss]

Hey, do you know a good place to find go karts for cheap? I’ve always wanted one but I’m poor. Thanks

[@dogetheshibainu608]

I have one of those and I think the clutch is broken

[@staceystarling15]

Have this same kart, just recieved my new 16 hp duromax. Ready to roll, accept, problem of course. So rear axle bearings r rusted, how do i remove them? Got tires off of splined axle (hard) and need to know how to remove axle bearings n rear.any help greatly appreciated

[@DavidRodriguez-fn4yn]

stacey may you have to completely remove the rear axle from the axle hangers. There will be 2nor three bolted holding it

[@robbyalbert4904]

How do you find them for so cheap?

To be honest the engine has potential it just needs tlc to bring it back and it wouldn't cost much just fluids gaskets and some odds

Thats the reason why those yerf dogs are not made anymore. The front ends were breaking off and hurting people.

it's not predator style, predator is the copy of a HONDA engine .. I'm surprised you do not know that.
