Homebuilt 100HP Go Kart Crosskart Track Day

[@chrisg6534]

Wow amazing, that looks like a blast. You are 100% correct - going from dirt to asphalt is a different game of tolerances. Great work!!

[@notaboutit3565]

Apology accepted lol 😂A liter bike motor, some slightly longer gearing, and a fine tuned suspension setup would dominate on a track like this one. Also I noticed you really heaving the wheel into some of those corners, this might be something to consider for you. I've been wanting to save this idea for my own build but, whatever, sharing's caring and all that. Years and years ago my dad, brother, and I built a go-kart kinda similar in design to this one, it was designed to look like the cockpit of a RAH-66 Comanche. Anyway, we used a 3:1 frozen yogurt machine gearbox as a kind of static "power steering". I've never seen anyone else do this on karts like this, but it was a massive difference in overall stability and confidence when driving the thing and more importantly, it wasn't exhausting to drive for extended periods of time. No plumbing either, it's just a mechanical gear reduction inherently designed to suffer millions of rotations and at least back then, they were cheap and readily available. Really enjoy seeing your vids man, keep it up!

[@2SanityAtitsBest2]

That’s awesome! Great idea. Thanks for sharing.

[@matthewmoilanen787]

Um or he could get a new rack with a different ratio and not booger something together. Racks are available in many ratios and they are designed to to do this.

[@bikerbrego]

That’s why I bought both plans from you. The two seater for the street driving at home with the 1400 and the single seater for fun days with the busa motor. Glad you had fun

[@KJRaycing]

One of my first thoughts was getting the two seater busa powered VF-2 there next year… nutty 😁

[@bikerbrego]

@@KJRaycing good luck and have fun.

[@ltsky311]

Nice man, 1 thing I can say, when money permits, race day in the trailer needs to have a generator and a small 110v welder, unless your gonna drop serious coin on a 3 phase genny. A nice jack, 4 stands, and a small kit of sockets, wrenches. Extra tires rims lugs and lug studs. Sounds like a lot but it should be enough to fix almost anything.

[@muckymoto]

Sam B and I were talking about this video earlier today. I told him I had not seen it yet since I just got in from work. I turned the lights off and cranked up the speakers. WOOOOOHOOOO! This is awesome! I will try and see if there is a track down in ATL that I can take mine too once its done. I did go with a larger wheel set 14" since I thought I wanted to take it to asphalt some point in the future.

[@NoahBanman22]

been loving the videos! If this gets popular enough I would love to see a racing class with this chassis. Could set up below 1000cc classes and below 600cc classes. Set up rules and regulations. That would be really cool. Have a great day!

[@KJRaycing]

That’s what we’re working towards! Thank you so much. 👍

[@2SanityAtitsBest2]

While you can put down more power on asphalt, it becomes far more dangerous at those higher speeds. Lower, stiffer suspension, tuned engine, and see what kind of additions might be good regarding safety in the event of a crash. Thanks for sharing. 🍻

[@chrismustry9302]

Higher speeds are more dangerous? Say it ain't so, Karen....

[@cousin_JACK]

thank you so much for taking the extra effort for us all. This is very enjoyable content 👍👌

[@matthewjackson9765]

Cool vid, you should definitely consider some arm restraints, or window nets, or both before next time.

[@chrismustry9302]

Safety inspector(s) at the track day event said they weren't required

[@RattleCanCustoms]

Dang that looked fun! Might have to find a local track and try it out ourselves 🤘

[@KJRaycing]

Yes. Track day was an absolute blast! I highly recommend, thank you for the comment brother 👍

[@RattleCanCustoms]

@@KJRaycing anytime bro! Keep on grinding and we will see you on the trails!

[@davidgeibel1331]

That looked like you had fun. Nest time I would add some window nets, just in case.

[@KJRaycing]

Man it was a blast! I have doors for it but left them off because I wanted to make it easy for someone to find something wrong with it 😉

[@johncarter3303]

Got a sub out of me. Deff gonna buy your plans and build one

[@letsfish4409]

You could make it more aeorodynamic. for example: a plexi windshield, some plexi side windows. But it looks and drives amazing already.

[@E.V.I.L.Gaming]

Amazing I'll be in touch brother in the process of gathering parts now want your ideas on a 3 seater wanna build 2 of them

[@KJRaycing]

Thank you brother! Sierra cars started developing a three seater after I put my two seater design out. Looks very similar so you could grab some ideas from how they modified it for three seats.

[@whitelinefever4865]

Awesome haven been able to start mine work just gets in the way

[@KJRaycing]

Tell me about it! I haven’t gotten to do KJ Raycing stuff in a long time! It was good to get back in the seat!

[@UncleRayRayGarageEmporium]

I wonder if you could build an unsprung downforce front end? Just mount wings ONTO the upper arms, not the frame. Rear would use rods attached to the rear arms. The rod goes up to the wing, and the wing is mounted to the upper frame on a high offset Heim hinge. Simplifies suspension due to not having to counteract the ride height compression. Also, I forget if you had antiroll bars on this one, but you're going to need them for body roll in high G force turns now as speeds go way up. Doubling speed quadruples G forces. Aerodynamics are probably going to give significant gains due to the unavoidable high drag inherent in this style build. Anything you do with it will still be a blast. Can't wait to see your higher displacement build jump off the drawing board...

[@KJRaycing]

Can’t wait to see your build, you have some great ideas! Thank you so much 👍

[@Erratic17]

I love your work!

[@KJRaycing]

Thank you so much! It is a blast building these and sharing with you guys.

[@mattbayada3011]

Awesome cant beat that sound, you have any Hill Climbs out your way? The Hill climbs in my area in Australia this thing would do great . No weight , perfect for tight corners the big cars would struggle against your cross cart.

[@Powercat46]

after watching this video it really gets you wondering how far your basic chassis design could be taken. Maybe a budget formula car, or a entry-level fully independent suspension oval dirt racer sprint car. The offroad rally course is a lot of fun but not everyone has a place to run those.

[@KJRaycing]

So this idea was the whole premise of the VF (variable frame) kart! I want to have one machine that can do anything through conversion, it is working out pretty great so far and it’s just going to get better as we find different setups! The creative minds of all the builders out there are really making this idea fly 👍. I can’t wait to see yours and how you do it.

[@samj1185]

That 600 sounds great and goes fast but can't wait to see a liter engine in it. Thanks

[@METALWERKS1]

Very cool ! Yeah this is why my aluminum homemade F1 car has a ZX-10 motor . I knew I was building something for track life and high speeds . Also why my car is 12’ long and has 16” tires . Great work as always sir 👍 wish I knew a way to send you pics of my creation ?

[@clivejuniornoconjo1556]

You could DM them straight to him and just ask him to repost it on his insta or even drop your insta in the comments cause I'm also curious to see what you've got...

[@dinos8557]

Great video and nice kart. At around 9:50 you talk about the failure of the clutch cable. Are you running a quick shift and auto blip on that R6 setup. May be something to think about. basically eliminates the need for a clutch pedal other than for starting and stopping.

[@StoryOfJames.]

Perfect timing :)

[@Thehorsepowerfarm]

Have you ever seen the electric power steering from hyper racing? It’s for outlaw karts but I was thinking it could work for cross karts

Looks like you should start building one then

[@louisaltman4993]

Have you ever thought about using a shaft drive bike engine?? Like a VMAX? I’ve had a 1200 Vmax for ten years now and cannot top it out without death wobbles 145 mph in fourth? I’m seriously considering building a cart with it and a FL350 Honda Odyssey I acquired cheap. Would love your opinion on the shaft drive part Thnx love your work

[@timothywilliams2021]

If you use a shaft drive it would eliminate the need for building the chain drive. I'd use a small automotive rear diff. I'd look for one with a variety of aftermarket parts and gear ratios available.

[@matthewmoilanen787]

Shaft drives work great but the only downside is changing gearing. Gear would have to be made by a competent machinist with hyphoid gear cutting capability. As I worked for a manufacturer that did that I don't know of anyone who does it for individual customers? Good luck with your idea!

[@timothywilliams2021]

@@matthewmoilanen787 That's exactly why I suggested using an automotive diff. I'd look for an independent rear diff from a fairly popular car. Something with aftermarket support. Maybe a miata diff. Or a Dana 44.

[@lightning9279]

Not a big fan of safety, but in this case get some nets. One roll at high speeds and that left arm is history.

[@KJRaycing]

Put nets on yours when you build it then…

[@dodikurniadi4846]

Salute 👍👍👍

[@RAM7RO_BU1LD3]

Sounds great!

[@grantholcombe5112]

600 would probably be perfect for a mixed surface. Seems like it was only the straight where it topped out so maybe a gearing could help?

[@KJRaycing]

It was geared perfectly and plenty fast, I was just not pushing it as hard as it could go. I was learning the track and shaking down the machine in asphalt so I may have been a little too reserved.

[@grantholcombe5112]

@@KJRaycing that's understandable. Very cool to see one on a road course, thanks for the video 👍

[@brainstain22]

Man.....I sooo want one of these. Are you @ VIR?

[@kenan8795]

Why you did not show us gps speed from go Pro camera? Just import it.

[@KJRaycing]

Damn I forgot all about that capability, just checked and the gps is turned off 😡. I’ll try to remember for next time.

[@paulteirney3587]

The true speed is the size of the tyre rolled on the ground by seating in the car and marking the tyre and the ground then rolling the car in a straight line till the tyre mark is at the ground again. The dia of the tyre is not the rolled tyre dia which speed is measured by the speedo.

[@CasaMaryParadise]

GPS?

[@randythayer8440]

You could probably do quite a bit better with a shifter cart and different gearing. It seems a little slow and clunky on a track, though. It's probably better off-road. Fun, though, huh?

[@KJRaycing]

Yeah… check the redemption video. It was my first time ever on a race track with one of these. I brought back what I had learned and smoked everyone 🤓

[@hunterlogan2913]

Lower & wider, a little longer and a lot more power, aero, better tires

[@KJRaycing]

Sounds like when you build yours it will be so much better than anyone else’s. I can’t wait to see it 👍

[@hunterlogan2913]

@@KJRaycing I'm not a builder, well exceedingly competent One. It's not my interest & best skill set. I'm a driver who has an understanding of the dynamics. I bought 75% of my rides from the manufacturer including as of late C8 Z07. I have worked with some --too many-- speed shops who are wishful thinking as in poor in managing the needed task(s) at hand Your very high-end backyard kart is awesome times two!! Same kart somewhat modded on paved race track / road course, wrong idea! Think Formula 1 to Porsche 911. Shifter karts are great for what they are but IMO not the right business growth path ~

I was checking to see if you were just a run of the mill douche or a full on total douche; Thank you for answering that question. Enjoy your factory rides while all the people lesser than you try to have a little fun. Passing tech inspection is passing tech inspection no matter where you drive or race. Fortunately for me “opinions” like yours are meaningless and the build quality and setup are what matter. Oh and I was the fastest car on the course in case you missed it, and didn’t crash or die because my build is safe enough to be there: imagine that…

[@chrismoody1342]

There has to be a whole lot better performance left unused. A friend had a 250cc shifter cart and he would easily surpass 120mph.

Totally agree. Looking into smaller racing tires and a gps speedo…

[@drjimjam1112]

Looks too narrow and unprotected for asphalt. Also seems a bit underpowered. Just looks out of place, dirt car on asphalt.
