test riding the two speed go kart

[@aleblanc3547]

Yeap, the transmission did it's thing a lot better than I thought it might. What a screamer...51 MPH that close to the ground has got to feel like 100 in anything else.

[@baddage]

It shifts better than I thought it would. The drive pins act as a synchromesh to get the sprocket hubs up to speed. Pretty cool!

[@mackbreakerpuch]

damn never expected it to work that well, good job man!!

[@71MercuryCoupe]

Find 'em and grind 'em, still an awesome setup nonetheless, makes me want to try and build one

[@redorrick427]

Why don't you all relax and give the dude some credit'.He said it would go faster.To me that's fast enough with a twitchy steering.But it should go faster like he said.By the way,lets see all your builds..........Yeah Thought So!

[@JimmysTractor]

11:04 good thing you shut it down. Those little weights cause alot of damage when they fly off. Don't ask me how I know!

[@allenmckinney9533]

I was expecting to the 1st gear chain to come off.

[@RichieRichOverdrive]

Me too, he might need a half link rather than a full for that one.

[@Dennis-pe6zx]

Allen McKinney looks good but are u able to get rid of some slack in the first gear chain? Between the looks and sound i thought it was gonna come off.

[@rscarawa]

Me too. I thought that chain would hop the sprocket too.
Also, open up the holes in that disk so they are more elongated. That should make shifting a little faster with reduced grinding.

[@MrRenoman2011]

Great video. On the issue of a two speed mini bike I used to have a fox that had a two speed. The way it worked as that the engine was fixed with two centrifical clutches that engaged as different times. When it got to the speed that the second clutch would engage the second over ran the first and there was a one way bearing on the jacks shaft that let the first run freely. I believe there was also a one way bearing on the second that the first gear would use when the second was not engaged. Was a real cool system and compact. Just thought I would share.

[@carabela125]

Back in the day, Heathkit used to sell a 2 speed minibike with a similar shift but it was really lightweight; it could only be shifted when not moving. This is a great build ! My suggestion is to rubber mount the shifter. On motorcycles they have rubber in the back wheel to take the shock of shifting.

[@vtecbanger3180]

carabela125 a cush like a street bike

[@avinshetty5363]

good work bro....i think no one can hate your work brother.....u explains in the much understandable way...

[@bucktoothbettysboyfriend11]

GREAT JOB....... DON`T LISTEN TO THE HATERS. KEEP DOING WHAT YOU DO.

[@RichieRichOverdrive]

Good job on the shifter setup! Shame about the torque converter, I'm sure you can work it out though.
What you should really look into for your karts is caster and ackerman angles. Caster helps autocenter at speed so your steering isn't so jumpy, it'll always return your wheels to straight forward. Ackerman angles has to do with your steering arms on the spindles. They should point towards the center of your rear axle. They just help with your turning radius. With the correct ackerman angles, on turns your inside front wheel should turn sharper than your outside wheel.
Just some suggestions.

[@ClumsyCars]

I too watch project binky. lol

[@firemanjim324]

J&A Lawnmowers you need to add akerman to your steering geometry. Your steering arms should point to center of rear axle, and be BEHIND front axle.

[@lfc6183]

[@Blu0tuth0ninja]

Put some spring pushed friction plates that spline with the transfer wheel. Could make shifting alot smoother by acting as synchronizers.

[@FalloutNewNarwhal]

Ace! NOW TURBO IT 😂

[@lulink99]

Nice video and really cool transmission! I think you should just add a mechanism to fix the shifting lever in the three different positions. (1st, 2nd & neutral) You could do it simply by adding a spring that pushes the lever in a grooves on a vertical plate.

[@slrs3908]

Love it! An ingenious design. Back in the 1970's Kawasaki sold a trail bike with relatively low power that was compensated with a 2 range transmission. It had 3 or 4 regular gears, but when stopped, you chose high or low range depending on the type of riding you planned on doing. Low for trails, etc., and high for on road for top speed. That is the only way I could make sense of you using an infinitely variable transmission (that shifts automatically) with a 2 speed transmission. No disrespect, because it is an awesome design and well carried out, but other wise, with enough power, you don't need 2 transmissions. A simple centrifugal clutch would also work well for shifting a 2 speed and might be even better (simpler).

[@tellmesomething2go]

What might help, is to bevel the leading edge of the receiving holes, so that the pins are already below the face of the discs, by the time they are directly over the holes.

[@gregorymessenger2093]

Man I love it hahaaa you're crazy but it's good to have confidence in even the most thrown together go kart hahaaa great stuff :)))

[@poco1990]

You're thinking,planning,building and learning. Awesome keep it up young man!

[@jpwipeout99]

That was awesome man!!! That two speed worked beautifully and I love that camera angle by the way. The test drive was a little long but man pat ur self on the back. That was a huge success!

[@normdoty]

excellent design and workmanship !!!! chains need some tightening maybe try a HALF LINK if the chains sprockets or shafts can't be moved... on the device that comes un done possibly use locktite on it, failing that you could try left hand threads re thought - you could use safety wire to lock the bolt in place much easier / simply drill a hole thru the bolts head and a hole thru something else to wire the bolt too . the slider on its shaft, possibly use 2 or 3 keys / key ways, giving more longevity / strength.. excellent keep up the great work. used to do this kind of stuff in another lifetime.. you make me proud brother ..

[@mrarkane]

Hang on a minute, you have effectively added high and low range to an infinitely variable transmission to begin with. Nice work you do BTW.

[@suntzu6122]

Fuggin love this channel!!!
Great work man keep it up!!! So badass!!

[@tombenes4461]

Looks great only one thing I would do differently is tighten the chains

[@delifruityicecream2663]

Awesome work. Been thinking minibike the whole time too. Looking forward to your next build with this limitless potential.

[@benoitdebrueker2500]

Amazing.
Just add some idler gears to stop the chains flapping and you going a real good gear train.
Look up "dog clutch", it's the same idea as your prongs and holes system but more robust.

[@kenbrown460]

I agree amazing. But I disagree on adding more unnecessary moving parts. He just needs to adjust the tension on the chain alittle.

[@codycheney3401]

So imagine if your rear tires were 4" taller ! Your speed would be perfect ! I looks to be a fun cart I will have to look at the build video again and see how you made it ! 2 Thumbs up ! Maybe try a heavy duty spring to keep it in gear ! I think that you really have a winner here now if you could figure out a reverse gear to go with it ! Can you do a video just on how you made the 2 speed with the torque converter that is in iits self a two speed so you really get 4 speeds on paper any way ! great idea !

[@adamthomas892]

cody cheney reverse would be awesome!

[@glenjohnson670]

cody cheney i

[@gijs.22]

cody cheney i think he needs a shift lock just a little lever on the shift handle to release it if he pulls it

[@mk5455]

There's a reason why go-karts have low profile tires, the larger diameter would make any kart unstable. You want more speed(????) add another tooth to each sprocket. Very impressive young man. VERY!!!

[@kenbrown460]

It's already geared alittle to high as he even said. Putting tires 4" taller will add so much circumference it will want to do 80+mph but won't have the torque to ever get there..lol

[@fan1701]

That thing works really good. I wasn' t expecting that. You have got a winner there. You are right, a minibike with that trans would be killer.

[@rockofagesusa7942]

Thanks for the ride

[@WarrenGarabrandt]

That works much better than I thought it was going to. Good job!

[@michielcouvreur]

Very good job man, I'm planing to make a 2 speed bike with belts. Do you have video how you made the gear system?

[@tomharrell1954]

First super great job! Your ability to build the cart is great. Because you are able to reach 50 miles per hour your engineering skills must catch up with your building skills. 50 mph has more than enough kinetic energy to get you killed. The previous comments mentioned steering Caster, camber Ackerman Angles, Loctite, safety washers, the steering linkage geometry, roadworthy tires, and wheels. Your achievements are great, I just don't want them to get you killed. Lastly driving on the highway is dangrous. Old farts like me may not see a little cart. Being squashed may not be so much fun.

[@hunterpetrovich5036]

You should make some kind of synchronizing ring out of rubber or something

[@slaapkonijn58]

Hunter Petrovich was thinking thesame thing

[@all4amd344]

Hunter Petrovich he could make the holes for the studs to go in oval.

[@twoeightythreez]

He could cannibalize an old th350 or something for the frictions lol

[@osquad1346]

This is freakin awesome nice job man btw can’t wait to see more videos on the dune buggy

[@JagMods]

I've followed your transmission build. and I'm impressed. Nicely done.

[@kuntrekuzzin]

Ive been following your videos for a few years now and dude your getting better and better hell my uncle subscribed as well

[@morganberrigaud2670]

Very interesting, i watch you fromage France still 6month you have really good ideas i love your videos👌🏼

[@markozbirn2080]

I seen this done before with the transmission being it on unit, you did a great job on your design by using one less shaft and bearing. less moving parts means more power to the tires. Good job

[@kenbrown460]

Awesome job man !! Everybody needs to realize this was it's first test drive. I'm sure hes gonna adjust the chains and do many tweaks. If you watch the previous video he pretty much freehand engineered it. Just grabbing pieces of metal holding it where it looked good and welding it just to test and see if the transmission even worked.

[@bryduhbikeguy]

Awesome ! Glad the converter came off at stop.Wouldn't have found it all if at speed.REally Great build>Thanks for showing us.

[@SeaCowsBeatLobsters]

Your 2 speed trans design is elegant and simple. I think it has a lot of potential. It might be easier to shift if you made slots instead of holes for the bolts to catch in.

[@RichieRichOverdrive]

^^^^I like the slots idea
But you'd need a milling machine and a rotory table to make those rounded slots(or a cnc machine).
Also, having the slack in between the pins and the plate might accelerate wear, or shear those pins. I think I heard chatter in his setup as it was. Also, the less consistent power of the single cyl engine increases the chatter.
Just in my thinking, though.

[@akio2589]

It'd be clunky. Literally. When ever you applied/released the throttle, it would clunk as the drive would catch up axle or vice versa.

[@SeaCowsBeatLobsters]

good point. maybe having slots that start at the face of the disc and gradually deepen, though he would still need a mill

[@InsideOfMyOwnMind]

Just leave them both engaged, add another torque converter and switch between them. That's how many modern vehicles work, no more grinding and instant shifts.

[@rickeybowman8583]

I really like your design. I think it could be improved using some heavy duty springs and gears from a "lunchbox locker".

[@bobcat9314]

Dude..that's insane..haha..looks like a great project..nice job ..keep safe so you can keep posting videos of all your cool project..there exciting to watch..thanks for posting

[@robertirish2275]

Very nice and simple design that worked. liked it very much. keep up the good work.

[@thecrazymanfromireland]

Over 50 mph dam that's fast for a home made go cart super video thums up buddy

[@TheRonin508]

Awesome job. Great idea. Check out how a 2 speed transmission works on a gas powered R/C car. Very simple, adjustable, and automatic.

[@kbakeritsallaboutnobody.5761]

Not to say I was thinking it was going to be a failure because I am VERY impressed with how well it works. You could play around with different tire sizes. You made it this far. You can figure it out and make it work. Good job and and nice video! 👏👍

[@lilflatty2472]

Wow that’s pretty ingenious! I build all kinds of crazy/wacky stuff myself but that trans is really cool!

[@Joe_1971]

That's an awsome build bro...great job. You have a really nice work shop.!!

[@r.j.burmeister6147]

Didn't think itd work but did very well. Nice job bro

[@amcustomfab]

grate work amazing what you accomplished with so little resources.

[@crazypeopleakronohio2191]

Truly a good build man... I wish I had more friends like yourself....

[@grantdeisig1360]

Very well made. When I was younger we just used the secondary and gear case off a bombadier snowmobile, and ran a yamaha two cylinder 399 engine. We achieved speeds of about 50mph, but the torque was where the fun was at. The only thing that I really hated was the solid rear axle. Next time I'll use a rear differential so we can turn much nicer. Good video though!

[@Mtlmshr]

Hey you figured out a " Crash box!" Lots o fun!!

[@firemanjim324]

The first video I saw of yours was a weak ass attempt at building a kart using a self propelled mower engine. I told you to quit wasting your time and build something worth your time and money.
Well, you did just that... I was blown away with this build. You did a fantastic job !
I have a 2 speed automatic transmission on my Sears roper mini bike. It has enough torque in first to ride a wheelie and hits 65+ in second gear. It is comprised of 2 cent clutches , one using a one way bearing.. it's an N.O.S set up I bought off eBay. It ran around $300 in total , plus a reproduction mount I had made . I believe it was from a company called black widow....
I want to put it on a light street kart.... I think it would be a blast.... and in thinking of how the transmission works, a 3 or 4 speed could be engineered , I'm sure....
Love the new skills you have acquired. You got a new subscriber....

[@phildoethedildoe]

Pretty cool cart there! i machine a lot and this gives me some idea's for my buggy i have!! I like the build video where you show how to mill the parts for the 2 speed system, You ought to take a look at the first gear chain and take one link out of it as there is far to much slop and play and at high speed it could catch and bind the gears. Still...it is an epic build and nicely done!!

[@nandito7021]

well done buddy hope to see you on a near future owning a car factory thats how most of the well-known car brands started their bussines thumbs up👍👍

[@barrywithers8913]

Well Done !! luv that gearbox ,,,,,

[@phill903]

It is amazing how well your two speed works.

[@gwood64]

Rupp had a 2 speed setup that used a one way clutch and two centrifugal clutches. Worked real slick, all automatic

[@SmOoThYwOoDy]

Looks like some fun roads to drive on, lots of curves. 2 speed without a clutch is awesome.

[@bobbywarrior1434]

Congratulations on your success, it takes a lot of thinking and will to achieve things , keep it up you will make great things

[@1teddy1979]

Ya man that is awesome!

[@theupscriber65]

Nice job. You didn't listen to the doubters (myself included) and it worked!

[@Wilson84KS]

Great work man! Also it's a nice place where you live, much space and surronded by trees, I'm a little jalous ;-P

[@Bobby8451]

11:07 LMAO!!!!!!!!!!! GOOD STUFF

[@ronaldnickell6110]

Great job. I believe Northern Tool has a little rack and pinion that would work for the steering .That might make it a little less sensitive, but still give a relatively fast response, just a little more turning of the steering wheel.

[@kwik440]

Genius !! man that thing flies !

[@kilogram064]

That's pretty darned smooth.

[@hunterpetrovich5036]

I knew that pulley was gonna fall off at some point! Lol

[@texaswildcat2000]

Shift lock....simple....move lever to side, spring loaded, move forward (or back) and let the spring pull it back into a detent (notch)....2 notches, 1ea gear...you'd have to build it, simple tho, and I'd recommend install just above the base so you keep the same pivot point for forward and backward movement....

[@1981dasimpson]

works better then i had expected and no where near as much grinding and missing of holes that i thought they would be well done

[@aircooledtx]

Need smaller steering wheel. Take my advice add roll bar. In 80's I flip similar go-cart about 40mph , took hide off both arms. The problem was ,wife was at work about 20 miles away, and no way to get to hospital, wrap towels around arms and waited. Never rode another cart. No roll bars,if had them would not have been as bad.

[@victor280768]

NICE PROYECT, CONGRATULATIONS!

[@jcustomdiy3661]

Awesome work I really like it . It work like a old gear box and one think more, if you work on gear ratio you can definitely achieve good speed and a synchronise dog clutch mechanism that care your gear shift mechanism

[@rockofagesusa7942]

Like you’re shop and your cool ideas , I think I’ll steal some of them hehe

[@JeffreyMaysjmmods]

great job!

[@ericlarreau5498]

on your shifter... spring-loaded trigger connected by a rod to a pin down below... a simple fore-aft gate shifter, a slot with a hole on each end... pull the trigger, move the lever forward, drop the pin into first... pull the trigger, move the lever back, drop the pin into second...

[@billylatham9183]

Good job Guy ! Keep at it.

[@adamthomas892]

Cool project, it reminds me of the way dog boxes are made. To make the shifting easyer. You could have your "dog" engage into slots that are larger than the pins, so that when you shift it's more likely that the pins will hit a hole than skate along the plate, the only problem with that is that you add extra lash to your drivetrain, just a suggestion though, and super cool. Is it a waist of time? only if you didn't learn anything doing it.

[@exercisemyrights]

good stuff man.ingenious..
watch them sketchy tires..50 mph is no joke

[@RcMicroFlyer]

11:05 The weld on the big sprocket is cracked. Very nice project though :-)

[@DktheWelder]

Cool idea seems to work well to lock it in first or second move the pivots of gear lever together so when in 1st it goes over center forwards then second is over center back

[@keun2009]

You're crazy man...!!!!! Hahaha....Great job & nice place to live!!!

[@MrMoo-kb7rl]

Add a sheet metal plate with cut outs for the shifter to rest in and then have a spring pulling the shifter towards the cut out, so it locks in gear, Great job on the build

[@sergiocarrasco9288]

Buen trabajo amigo. Felicidades. ..

[@rickjames4630]

Badass bro!!!

[@badbadbrian3820]

That's awesome!!!!

[@Neuron43]

With a first gear like that, who needs second? he he. I was surprised to hear that the steering was too sensitive because it seemed to handle very well on the corners. Maybe it took a lot of upper body strength to keep it in line though. I also found the gear shifting surprisingly smooth. Overall very impressed with that build.

[@trimbot6]

I suggest you chamfer the holes the dogs engage into in a tear drop shape to lessen the wear otherwise an innovative, effective garage built go kart, looks like a lot of fun, enjoy! Thanks for making the inspiring video..........

[@james-jl2ej]

[@715101]

That worked really well I can't believe that It shifts both up and down so smoothly on the move
Aim for around 5.5:1 for first gear and 3.5:1 for second on your next gearbox 👍

[@JoseRochaMicroondas]

excelente Muito bom Show de bola

[@fortj3]

I'm very intrigued by your two speed transmission. It could use some tweaks, but you proved that it works. The hard part is done. You could always spring load it to the high gear position.
You hold it in low until ready to shift into high. Then, let off the throttle and shifter, to go into high.
Or, you would work out an over-center linkage that will hold it in each gear.

[@smallenginedude71]

now this is some fucking cool stuff!! excellent work!

[@andrewkramer3011]

I reckon that shifts similar to Semi transmissions. Those aren't synchronized like car transmissions so you either have to double clutch or float the gears. Keep shifting that thing smooth and you'd be able to ride a big rig down the road.

[@seanbinyamin]

you have to build the mini Tank whit 6.5HP !!!

[@ctbully]

Wow it actually works, with a small bit of grinding. Amazing. Hey they place where you live looks really amazing.
