Harbor Freight 459cc CROSSKART?!?!

- Опубликовано: 21 июл 2024
- So now that it is built it is time to upgrade some things. First things first: Electric start ($100 battery), Super adjustable metal plate CVT mount ($160), Racing Seat ($288) and a GPS speedo mount ($20). I know the racing seat is expensive but it is definitely less expensive than adding a rear suspension and seems to be doing a pretty good job absorbing some bumps. I borrowed this seat from another kart for the time being, now I have to save up for another one because it works so dog-on well.
I'm waiting for parts on the two seater and can't wait to get back to work on it!

Love the look of this build ! Really nice work
Thank you so much! It came out better than I thought it would for sure!
Amazing job with everything you have accomplished so far! I’m really excited about the two seater and whatever it’s coming next on your list
Thanks man! I’m always cooking up new builds. I wish I could do this full time for you guys. I would have something new all the time.
Love this! You’re making it affordable for anyone to build their own!
That is the idea! Now to get some suspension on it and get it ready for busco 🦾😁
I ready to see that 2 setter come together I know you don't have much time for filming as we all have a live and work to attend to but I THINK YOU for all you are doing for us FAN'S
Thank you! I’m still working on it. I’m designing and building suspension options 👍.
Hey @KJ Raycing! Love your stuff man, you got me inspired and I built my little prototype kart too ;) to my level, of course. So out of ingenuity, I used a 4-wheeler swingarm for the rear, never seen that setup before and it seems to handle, the only gripe is of course the swingarm pivot vs. countershaft sprocket thing, you know like in full suspension MTB's, it causes chain issues , I still have to perfect a chain tensioner (of course you wouldn't have that problem if you got a solid rear or a differential). So this kart's engine/converter setup looks a bit like the one I did, in my design the motor doesn't swing with the suspension ( a feature I wanted) it stays with the frame and the sproket close to the swingarm pivot kind of allows it to work, although chain guides are a must.
Rear tire size and sprocket teeth count? Sweet ride!
Nice job, throw a pipe header on there and run some VP 94 fuel and a measured amount of VP octanium and you will see a signifying amount of performance. We run that in our buggies with tillotson 212r stage 2 engines with a juggernaut. Have fun and make some memories. Also the rfy shocks with a resivoir helps out a lot as well.
Thank you! Power mods are 100000% on the to do list. It’s hard to tell the power increase if you don’t start at stock. I’ll get a stable chassis on full suspension before I start playing with the motor. Stay tuned!
You should build one of these with a hopped up predator vtwin. That would be pretty cool. Mid between bike motor amd budget build.
It would be awesome for sure… but for v-twin predator money I would just put an atv engine in there like I did the other ones. The one I have with the bike motor was actually the least expensive to build after the budget kart of course.
Nice to see how well that 459cc moves it stock! I'm building a full suspension off road kart out of square tube. Using a 440cc with some modifications (stage 1, governor removal, and billet rod/flywheel for safety). Any idea what the weight of yours is?
I honestly don’t know the weight of the budget build. I’m guessing 400 or less. My 8 year old daughter can push it around the yard so it can’t be too heavy. A fully built chassis weighs about 115 lbs before adding anything. And I didn’t use all of the pieces. Spending $150 on 4 analog scales seems like an awesome idea until it’s time to hit the checkout button. I’d much rather get something towards building.
@@KJRaycing Yeah I understand that. I can lift my frame by myself as is right now, that's with the steering system in place but nothing else. I'm just glad to see how well that thing performs being stock. It may be the slowest you have as of now but it's my personal favorite!
Quick question, how did those gussets on the CVT plate work? I have the same issue with mine (very similar aftermarket backplate to yours, just a different manufacturer). Mine is 1/4" steel. Thinking about welding some 1/4" flat bar on mine just like yours.
The gussets definitely worked but check out the latest video with the comet 44 magnum, that really made the driveline perfect. The basic 40 series clutch was jumping around causing the flapping of the backplate.
how do these do in soft FL sand? I would think the light weight helps. Would be interested in what tires / chassis height others have gone with for soft sand.
They go great in New York snow and carolina sand, I’m guessing they would do just as well in Florida sand.
Sweet! You can cut the grass with that thing! Alot more fun than riding a lawn mower... Nice work.
Thank you and yes, it is more fun than mowing even without the cup holder 😁
Put the 459cc with a GPS Torque Converter in my Maxxam 150cc and it ran good for about a month and then the engine blew out the top out of nowhere!
What size sprocket you running?
Hey can you tell me what kind of ball joints you have on your front a arms. Im having trouble finding the right ball joints for my a arms
I use sport quad atv a arms. So everything is replaceable with high quality parts.
Must take a lot of time and money to maintain that large field of grass!
Does it turn better with the steering rack at the back or about the same ?
About the same. It could be better but not obvious because of the solid rear.
What size wheels and tires do you have on your 459 cc cart
I really want to build a couple of these, not so much the straight axle rear end model, but im curious what the overall finished width is for these. Wanna make sure theyll fit in my cargo trailer is all.
I really hope you get the chance to build them. They are about 62” wide. There is a crosskart specs and dimensions video on the channel that will tell you more.
@@KJRaycing i appreciate it, i toyed with buying a chassis out of australia years ago but could never justify the cost. Ill be building at least one of yours this summer, would love to bring these out to the flat track events and hopefully get another class going! Ill be buying your plans here soon! Amazing work youve done! Ill get ya footage and pictures when its done!
@@KJRaycing got the plans, rogue fab bender and notcher on order; and all the metal priced out, i cant wait to get started!
Im torn on donor vehicles, part of me wants the ease of the polaris outlaw setup (wish i could find one as cheap as you did!) but wrecked bikes are so much more common and a lot cheaper. That protodie rear end set up looks great, but i dont like having to spend a lot of money for a weak reverse.
Im wondering if reverse is even worth it, will the polaris set up pull it out from like a high center over a small berm? I dont expect too much out of it, but im wondering if i should just pull the trigger on the protodie set up and put a 600cc sport bike motor in it. I heard you briefly mention it in another video so i figured id see if i can pick your brain about it a bit. Thank you so much for all your hard work! I hope i can get at least one finished by september/october!
@@g00gleisgayerthanaids56 see that’s a tough question because I’m not sure what your expectations are or where and how you will be driving it. The KTM is my absolute favorite, it’s punchy and explosive and has reverse. The cool thing about the street bike powered ones is the rev range, having 14k to play with while drifting is incredibly fun. The KTM is super lightweight too and is less complicated for maintenance. I don’t want to steer you the wrong way, I’m just giving you my opinions. The protodie setup is definitely awesome and definitely expensive. I’m working on my own rear end but getting it right and making it affordable takes time and patience for sure. Getting an outlaw donor will give you everything you need to build one; which is huge. I haven’t “needed” reverse yet but it is a nice convenience. But if you don’t have reverse you drive like you don’t have reverse. I’m really excited that you are getting to build one and thank you so much for joining us on this crosskart movement!
@@KJRaycing yeah i dont expect much out of reverse, im down in florida so a lot of sand but weve got some clay tracks and a few spots with real dirt. A lot of road courses and rallycross events to ride.
Im just struggling to find an outlaw donor for a decent price, not many of those quads around me. Cheapest ive found is 3k and it doesnt even have fox podiums, just no name off brand coilovers. Plus the axles are toast.
The more i think about reverse, the less i imagine ill actually need it, id probably use it primarily to back the kart into the trailer, to squeeze in a second one.
Thank you for your detailed responses! Ive been wanting to get into crosskart for years! I think itll really scratch this old group B rally itch that ive had since i was a kid!
the commenter was right; your clutch broke because the chain tension was being applied far away from the casting, creating a big lever arm. The chain tension is much higher than the belt tension.
He was right. We got it figured out and now there is 100’s of hours on the current setup with no failure. Thank you.

It appears the 40 series driven was reversed...it's meant to ride inboard, unless you change to a reverse wound yellow spring.
I ended up getting the drive sorted out. It took about three rides and some research but it is golden now. 👍 Check the next video.
how did you extend the electric start button?
Wire by wire. It is very easy if you don’t overthink it 👍
Arek You have any project?
How has the torque converter held up
It is absolutely flawless. What an incredible setup!
New sub btw.
Buenas tardes, como puedo conseguir los planos?

Is this frame available for the public?
Check the description if the video for all the information 👍. Enjoy the build.
I think the first backing plate broke because the sprocket was on the outside of the driven pulley.
The sprocket wouldn’t fit between because of that flange. The output shaft on the motor isn’t long enough to hold the clutch in your configuration. So you are right for sure, but I couldn’t do anything about it.
Blast LED 40 series. The only way to go.
You need to flip the driven around. The sleeves have to be opposing. You'll be eating belts when climbing hills. Plus your only getting about 70-80% of that engines power. The driver/driven misalignment is eating some of your tourqe and alot of your top end.
@@igokarts4510 the first torque converter kit he had would have been perfectly fine if he would have mounted it correctly. That specific kit calls for the dry clutch to be mounted inboard, where the retaining nut is facing the crankcase cover of the engine. I know it sounds and looks crazy that way but it works flawlessly. How to use this kit with a Kevlar belt for a year and a half now with a built 460 with absolutely no problems whatsoever.
I see what you are saying; but they are aligned… when the clutch is engaged the belt is perfectly straight. I’m going to flip the clutch/driver around the next day I get to play. I believe you, just don’t understand this stuff 100% yet. We’ll get there!
@@KJRaycing guy named Gozz on RUclips explains it perfectly
Son unos genios!!!!🏁👍❤
I think you were talking about me as far as wanting you to mount the drive sprocket inboard in between the driven clutch and the back plate. That is correct leaving the driven mounted the same way you have it now just moving this sprocket to the inside. Then you take the drive clutch off and mount it the opposite way, where the clutches retaining nut is facing the engines side cover. I will leave a link to what I'm talking about, after mounting it this way it'll work absolutely fantastic. I've been running this setup on a 35 Plus hp stroker 460cc for a year and a half now with no problems whatsoever with the same exact torque converter kit

Sir. When I said I went to CVT school I was talking about you. You are absolutely brilliant with this stuff. I know you flip the clutch but I’m just too new and I have never personally seen a clutch mounted backwards. I will definitely give it a go now that I have a better understanding. I had to just get a setup that worked before I could start tweaking and doing things I don’t fully understand. And you were not the commenter I was talking about. Thank you for your videos, I’m a huge fan.
Wish i could build me one, but make it road legal
There is some website that can help with that
as far as the seat prices, this is a fine example of corporate greed that has taken over america.
Top speed ?
I’ve had the 459cc over 40mph in stock form without hitting the rev limiter so I know it has more. My goal is over 60 but still be able to tear up some grass.
@@KJRaycing awesome, really appreciate the reply, hopefully they’ll make a performance kit for the 459 soom
Yeah. I’m realizing I should have went with a 420 or 670 for aftermarket stuff. But it is a pretty potent engine.
@@KJRaycing I feel like the predator engine is no comparison to a motorcycle or atv engine with a trans, am I wrong about that?
@@tjradford9565 a motorcycle or ATV drivetrain would definitely offer more power, but the appeal of the Predator setup is that our younger ones can enjoy the ride with just 2 pedals: "go" and "whoa."
Keep up with the donuts and you wont need a lawn mower ha ha ha.
I wish mowing the lawn was putting the 5 point on and playing for an hour 😁
@@KJRaycing Would make mowing actually fun lol.
need a skid plate. you will thank me later.
Are you serious on the price increase? Seen the price of gas? Food? Hell yes they have to increase their prices!
I know. It just sucks for us builders. I will not join in on the price increase and my plans will always be the same price.
First lol
