Thanks for the tips!

I'ma go at it right now and have a look at what you said, thanks!
I want to see this engine stay in it, but with performance mods. However, my guess is that it will end up with a Predator 420 in it. Which will also be cool.
I just recently started working on the one that I have. New carb, re-did the whole wiring harness, added a key start, new battery. Now I just need to get the front suspension fixed. The ball joints like to snap the ring that holds them in. I'm going to be replacing them with heim joints, but I do not have the tools necessary to do so, so I have to find a metal shop that can do it for me.
This GY6 is set up the Same as Common Scooter engines. CVT with the front Part with the Rollers, and the back piece with the Main gear ratio changer an the Clutch. They are also mostly Used in Chinese scooters as 50cc and up to 125 or 150. Think they were often Chinese Copies of Honda Engines :)
I have had one of these carts for over 15 years. I'm still impressed with how it performs. I found myself trying to give you pointers while you were troubleshooting it. Push the break! Haha A couple of cautions here. The original spindles bend very easily. Also, these carts are top-heavy and don't have that wide of a wheel base. They will roll easily if you're not careful.
I have two Yerf Dog Spider Box. The front suspension is a little weak where the Yoke connects to the control arms and a little metal fatigue fixed by re-welding the front end. Believe I have the manuals and sales DVD.
glad to see you guys start tinkering with the GY6/CVT combo. Lots of them out there and the CVT has lots of options. Just putting the 212 or 470 into different frames gets a little same old same old. I have this in a Trailmaster buggy and run it all over the mountains and thru the fields and hills on my property with no issues. Have fun
There technically isn't a gy6 250. You can bore it out to a 232, but a 250 is probably a roketa or honda engine. Water cooled, vertical head that sticks up?
I use to build this engines in Puerto Rico for scooter drag racing. Trust me, dont judge them because they produce only 9hp. You can build this things all the way to 232cc and the cvt have great tuneability also.
Now get some "works" brand atv shocks. I used front shocks off a 1994 honda trx250x on mine and made a HUGE difference. Also they where works brand shocks with remote reservoirs.
My son and I have a Spiderbox, did a tuneable CGI ignition upgrade, 180cc bore, performance clutch and weights, new higher clearance front end. Opened up the exhaust. Really scoots. Turned heads at Durhamtown. Glad to see you boys saving a classic!
YES!! I've been WAITING for you guys to pick up one of these! I've heard the GY6 setup is very efficient at getting that power to the ground. Can't wait till Wednesday!
Hey guy's this the same model Jaret and I rolled. Check the ball joints. We have a 420 on it, with Buggy Depot front suspension kit on it, with the heavy duty ball joints.. It's a really killer model. I noticed while it was first running there was a spark under the wiring harness. It was Brite enough I found see it.
I used to have one of these when I was a kid, rode it all the time with my friend and it was a blast. It would do 45mph easily in a 4 acre field, lots of mods available for them. I would like to buy another one someday.
Those lights are usually AC running directly on the stater not the battery. It usually depends if it has a DC or AC CDI. If it has a AC CDI, the stater is likely center tap grounded creating 2 'phases' and the lights and CDI are one one phase and the charging system is on the other. While AC CDI equipped engines typically use grounded stater's with half wave rectifiers, engines equipped with DC CDIs sometimes have full wave rectifiers with the stater ungrounded. Speaking of stater's they can have a 6, 8 or 11 pole stater grounded or ungrounded. The wrong stater or upgrading the stater without wiring changes and damage the CDI and/or blow all the light bulbs as ungrounded stater's typically produce twice the voltage Another thing to note the flywheel that comes with a 6 pole stater will NOT work for the 8 or 11 pole, there are 2 different flywheel designs. If you are planning to put lights and stuff on it for max charging go to a 11 pole ungrounded stater with a full wave bridge rectifier and a racing DC CDI with no rev limiter or at least a higher than stock rev limit. DC CDI's provide better spark but will not kick start with a dead battery. If your wondering usually the kick start is where the muffler bolt is mounted. But that's right ladies the rev limiter is electronic on these. ;) I have something similar and mine hit 35 MPH on Go Power Sports Street Tires when the engine setup was completely stock with a stock CDI. Lightly modded on street tires I've hit 45 MPH and can easily climb some pretty decent hills with 2 people. The GY6 CVT's can really torque through some pretty nasty terrain even with 22x10-10's on the rear. www.gopowersports.com/long-lasting-tire-set . As they say though 'mileage may very'. I have something similar to a Tomberlin Crossfire 150R with the 9.8 HP GY6. While you can get a 'BIG BORE' 180CC or bigger piston,bigger jug and head kit for these CHEAP, they tend to run hot and fail quickly. I kept mine 150CC and ordered a new $30 Carb, racing CDI and 11 pole stater and fly wheel from Amazon.
FINALLY!!! The gy6 is a great engine as long as you take care of them *wink wink* there many aftermarket parts and many pages to follow on Facebook the parts are very cheap and they are easy to build! Enjoy the new grounds! Ps. That 150cc gy6 can be bored out to a 205cc if it’s a B case gy6 then they can go all the way up to a 250cc liquid cooled they are BADASS!
I had a Baja dune 150 for 50$ and beat the hell out of it. Parts are cheap and very available. Put a light bar on it and washed it. Replaced carb for 20$ and sold it for 900$
Been watching you guys for awhile, have had mini bikes, worked on predators myself. JUST got a 50cc scooter with a gy6 50cc. And now you guys have a gy6. Hell....yeah!
@@St0nedCr4b no it really doesn't exist the commonly referred to as gy6 50cc is actually the qmb139 engine being misrepresented the reason for the division is in the United States most states have a 50cc engine law where 50cc or less don't require a motorcycle license but 51cc or more do. So gy6 ...cc was only for the engines that would require a motorcycle license in those states.
The Light only run when the engine runs. The CDI on that is an AC style one. Also the round black part on that spare engines that was major gear reduction is a reverse unit.
If y'all ever have issues with wiring or anything, I'm open. I just pulled a 150 engine and put it in a little 50cc frame, so I recently just had to go through wiring myself. So stoked to see y'all finally work on a GY6 though. They're really good engines, and can make insane power with cvt tuning and a big bore kit. She spittin for real though 🔥🔥🔥
Yes!! More GY6 content! My daughter has a GY6 powered hammerhead GTS150. My biggest problem with it is shifting. It just likes to grind. It’s not a bad machine for what it is. It’ll go around 35 mph. Just needs more ground clearance and a little more power
I have a 2017 kandi 150 it does 35 with two full adults frontwards reverse backup lights brake lights for headlights horn the whole works just like a car and they are damn good play toys you will love them
id never been much into go carts and really really not into cars, but you guys are responsible for my goal of fully fabricating my own reverse trike 48 CC road legal bike. Low to the ground, good suspension and one day a bigger motor around 60-100cc. Like one of those can am roadsters but made basically out of bike parts. Might use a big fat hill tire for the rear wheel.
hey guys the torque converter in those things use rollers in the front section and have specific weight to each roller. different weighted rollers mean different acceleration and top speed. also there are also performance cdi out there and different cam options that are pretty easy to get your hands on. also i don't think it has reverse, mine doesn't and i don't think they had different engines on that kart with reverse although i could be wrong. but there are different gy6 engines some have reverse i think but again am unsure. these engines were used in four wheelers and scooters, i think the four wheeler engines had reverse. last thing-have fun
Gy6 engines have a ton aftermarket parts for supper cheap big bore kits, nitrous, exhuast, “performance computer” with adjustable timeing. If you do keep the motor it should be alot of fun
Im experienced in gy6 engines. They are low quality engines but you can get some miles out of them by maintaining the service intervals. These are cheap copies of a old honda engine, they are mass manufactured in China. They usually come in 4 versions per CC, 2 shortblocks (10" wheels) and 2 longblocks (12" wheels), 1 version of each is marked with a "-J" or "P" in the engine number, the P or -J model has a little taller cylinder and head from what I've noticed. A normal problem are usually defective carburettor (diaphragm). They can also be very picky on the valve clearance (hard to start when warm etc). And if service intervals haven't been maintained they can blow, leaving you to replace the piston, cylinder and sometimes crank. A few times I had to replace the crank on the 125cc models since they started to knock (normal problem?). And in a few cases the stator has given up. Feel free to contact me incase you need any further information.
GY6 150 + 50CC Moped done the swap several times now best swap ever if you can find a used GY6 150 for a decent price. power increase from 2HP to about 9HP
Wish I'd have seen this video before I got rid of my gy6, couldn't get it to stay running and I never thought to hold down the breaks. Was on a similar go kart but it was a 1 seater
I have a Kandi Spyder 150, with me, my friend and a full tank of gas it was doing 32 miles per hour uphill. Combined weight with the weight of the kart included was around 1,300 pounds.
In general leave the black lead attached to ground and move the red lead around to check voltage levels. It is easier to spot voltage drops across connections and banged up wires..
pushing in bearings : get a fitting wrench socket for both sides and a piece of all tread with two nuts that fits through the square holes in the sockets and pull the bearing in by turning the nuts intoo eachother can use the same method for getting the bearings out if you can get to it from both sides
I just got done re building one they pull great but you need to beef up the welds on front end where it connects to frame. Also get a performance cdi makes a big difference in power
Most GY6's are AC power so the wiring is backwards. Also you do not need to remove the chain tensioner to put the reverse gear on. Go power sports has a good install video for the reverse. I would recommend you guys do a Taida 232 GY6 upgrade. 25hp at the crank and just over 19hp at the wheel.
Chris check out the Gy6 Buggy performance page on Facebook. Issac and JD can get you educated. Buggy Depo has everything you need to make the Spiderbox a beast
I’ve grown up riding one of those Yerf dogs and recently owned one those exact models. That engine will go you can drift it in some grass the engine could use some more power but she hauls. They’re pretty durable overall but with that being said the wheel has rolled off while driving and my recent yerf dogs frame cracked after hitting a log. I love the steering you can handle the hell out of that big buggy and it feels amazing my favorite part on the buggy. Good luck guys hope all turns out well one of my favorite buggies. Oh and front tires might need an upgrade they will sometimes struggle to grip and turn.
Not saying you “should” do this, but if you want to disable the starter safety switch, you can do it in a way that it can easily be switched back n forth. Pull the rod of the switch out which is in the start position. Then drill a small hole through that rod of the switch switch right up next to the switch body. You can then insert a cotter pin in the hole which will keep the switch out which is in the start position and Bobs your uncle. Anytime you want to use the normal safety position, just pull the pin.
If you take the starter apart, those little contacts on the inside have a spring behind them, and they're bad for those springs breaking. That's what happened to mine twice. I took the springs out of 2 ink pens and haven't had a problem since lol. Good luck!
Beef up the front end. I had one of those the spindles bend easily. And that center bracket where the A arms mount could use some reinforcement. Also more gussets on the top part of the roll cage
Gy6 are fun engines. They have a pretty big performance market. If your not happy with the acceleration or speed you can change weights in the cvt and different springs for the clutch too. But y’all def need to get a new performance Cdi box. And jets for the carb.
I just got a yerf dog spiderbox that was sitting in a field for a decade. It was my wife's from when she was a teen ager.... After all new electronics and a carburetor the kart roared to life! I'm amazed that it was so easy to get running. Now I've had to tune the carb and currently have a 130 main jet and stock pilot. It is plenty fast with a tired old engine but it does backfire on decel. I need a larger pilot. All the ball joints are bad and most bushings are wallowed out. The shocks are bad the tie rods are bad the seat bets are shot, axel bearings are bad and the spindles are bent. But let me tell you. As is it rips doughnuts in grass. So much potential and so little parts. I'm sticking with the gy6 for mine but boring it to 160 or 170cc. I'm inspired to make a progress video now after learning about how popular these discontinued carts are and how easy it is to make a trail runner. ✌ good luck to all on your projects.
The way the cvt works is the engine runs the cvt (identical to a standard go cart cvt) then when the cvt spins fast enough the clutch grabs the drum which spins the output shaft
I say 50 horse motor with gears. Enhance the front suspension and get the rearend hooked up. Get bigger tires for better clearance. Good find Ike! Looking forward to Future vlogs on this machine.👏🏻👏🏻👏🏻👏🏻👍👍👍👍👍
The reason why the lights are like that because they hvae stators and the stators go bad in them and for the lights to work the stator needs to work for it to keep power going through the wireing harness
You should build the motor flat side oko carb , big bore kit , racing clutch and variator racing cdi and all that good stuff trust me it would be a beast
My brother actually had this same cart but in blue, gas peddle stuck and he was going down a dirt road, had the choice to go head on with a car coming down the intersection or try to avoid it by drifting and he chose the drift. Ended up rolling it and bone was sticking out of his arm and rocks inside of his arm also. Ems said if he would have went head on it would have killed him. Also turns out there was a recall for the gas pedals sticking on these things.
Change out the ball joints on your 3206. There was a recall on them but you can still get parts. I am working on a reverse for mine as well as ball joint replacement.
Just bought one just like that last week for 300 and the guy had a Honda 396cc beside it I bought for 150 and it ran first pull no smoke and it sounds great just pull start though
Just finished restoring my daughter's helix 150 with the same engine it does 40 with me and my daughter on it alot of fun but mine has reverse but you can add a gearbox on to those pretty easily
Yerf Dog really liked those GY-6 engines. We have two Scouts that have GY-6's with reverse in them. Neither one runs right now, but when they did, they we're gutless and slow. The engine in better shape is going to be made to run again, and the other one is getting a Predator 301 swap, with torque converter and F-N-R transmission, and re-geared so that it'll at least keep up with our tractors to be used as a chase vehicle when moving equipment.
Make that puppy a 180cc the biggest most 150cc gy6 can be bored to without major case mods 232cc with mods an a8 cam to make the powerband 5000 rpm to8000 rpm and u might have changed the gears to a scooter gear ratio in the rear end so ... they make tons of different gears to fix it but you gotta start somewhere and most gy6 engines need the performance stater for better charging and spark with the ncy cdi with no rev limit (12000 rpm max) this cdi is the best when used with the high tension coil also made by ncy and makes the hottest spark some ppl that drag race these melt holes in pistons the gy6 is my shit love those lil engines!
The GY6 is a very common engine in Chinese based scooters. Chinese built based on a 1980s/90s Honda scooter engine. They come in 125/150/200/250cc. The 50cc is slightly different. Actually good engines if looked after but terribly underpowered and the materials used are cheap. There are tons of spares available (here in the UK) and simple to work on.
bmi karts ounce sold a axle upgrade kit that gave a larger axle with bearings wheel hubs and wheels. The wheels were bigger and the axle was longer and thicker. I then ordered a front spindle and wheel upgrade kit. This things was more like a side by side when it was done and went through anything you put it through. would never get stuck.
They're not bad, but if you're planning on doing like ATV wheel swap &going off roading be prepared if the wheels dig you're busting the case. We did ATV wheel swapped had to weld the front spindles back on & beef it up. Then put a 350 warrior motor on it after we broke the case. Then when that became an issue we just chopped the hole dog house out off a non vtec honda flipped it around, welded the rack & pinion. Welded to back of frame & sent it for about 2yrs til buddy sold it
just sold my gy6 buggy that I built from the ground up. with mods its not bad. I saved the head and put upgrade bits in the cvt. I think it would hit around 35. I know those things inside and out up side down and backwards
It’s a spider box gx150. Front ball joints are prone to fail. The gy6 is 150cc and can be bored easily to 180. Top speed stock is like 28-30. Rear axle is crap tent to strip at the splines. Carb upgrade would be a 38mm makuni with a 130 jet. Btw it will rev to 9k no problem.
I have a gy6 50cc Chinese scooter with a 100cc bore kit. I’ve worked with theses a lot and performance parts are dirt cheap I highly suggest you mod that engine rather then swapping it. It’ll probably be cheaper. That looks like a gy6 150cc you can buy a 171cc bore kit for pretty cheap along with a performance camshaft if you look into upgrading it a lot.
They are no speed demons, but when the cvt is properly tuned, they are fun to ride because they rev like crazy. You should look at RBG's Zircon videos, it's pretty amazing where it will bring you.
that particular type of CVT is very common on scooters...ive been working on scooters and small engines better part of 30 years...those are fun to play with...different weights in your front variator will change things like takeoff speed....light weights will keep you in a lower range then say heavier weights will...with that heavy cart tho im not sure what effect it will have ...unlike the scooters...i currently own a 2003 yamaha zuma...i have a polini performance CVT in mine...fun stuff guys...you guys do stuff like me and my buddies tried doing years ago....
Guys! The gy6 150 on my Yerf Dog is a little beast. These units are cheap to build and can really push. Mine has $200 of upgrades, but the best bang for the buck is changing out the stock variator roller weights to 10 gram sliders ($24).
Gy6 scooter engine upgrade part is plenty.. stock gy6 is 125-150cc.. can be bored to 180cc ish safely provided u do upgrade the cylinder head and bigger camshaft... Pulley and roller kit plenty on ebay... Heck even diy injection plug n play kit also readily available
*CarsandCameras* I predict a 670cc swap, do they make alot of performance upgrades for those? If it were mine I would find a late 80's - early 90's Polaris Trail Boss 250cc 2 stroke as they make 25-30hp and have a fwd/neutral/reverse gearbox and torque converter style clutch all built in to a complete compact unit. They are on Craigslist all the time from $200-$800 and are extremely easy to work on. Excellent videos, I watch them all.
We have 2 of those, they have plenty of power and speed when running correctly.... Unfortunately they have a very finicky carb and ignition system, any small problem and they start hard or not at all and leave you stranded if you take them into the woods. 48-55 mph with a couple of big guys on it. FYI, if you throw those bearings in the freezer for a couple hours they will slip right in without beating on them.
Thanks for this channel. You guys rock. You guys inspired me to start tinkering again. I'm putting the motor/trans from a Honda 110 3 wheeler into a mower frame with live axle right now because of this channel
I’m currently in the process of putting a 420 on mine. This Yerf dog is called the GX150. They came in orange and blue. That’s the only colors I’ve seen them in. Model 3203 i think. Buggy Depot has many parts and info on this particular kart. Good look and I can’t wait to see further vids
You guys always find good deals, I have been trying to find a good deal but around here always trashy ones that want a fortune. They sell stuff no motor and busted frames for 500.00 the ones that don't look trashed they want 900.00. I hope to one day find a good one like you guys. Keep up with the educational videos.

The gy6 is a great engine as long as you take care of them *wink wink* there many aftermarket parts and many pages to follow on Facebook the parts are very cheap and they are easy to build!
Enjoy the new grounds!
Ps. That 150cc gy6 can be bored out to a 205cc if it’s a B case gy6 then they can go all the way up to a 250cc liquid cooled they are BADASS!
AMEN!
I had a Baja dune 150 for 50$ and beat the hell out of it. Parts are cheap and very available. Put a light bar on it and washed it. Replaced carb for 20$ and sold it for 900$
I’d like to see a diesel project 👍, using the China diesels. Something for the future maybe??
Been watching you guys for awhile, have had mini bikes, worked on predators myself. JUST got a 50cc scooter with a gy6 50cc. And now you guys have a gy6. Hell....yeah!
It's not a gy6 50cc that engine doesn't exist... however a qmb139 does and it is 50cc and is commonly mistaken to be a gy6 50cc which doesn't exist
@@dodgeme1986truck I type in "gy6 50cc", and a motor pops up. So it has to exist. But yes it's a gmb139 as well
@@St0nedCr4b no it really doesn't exist the commonly referred to as gy6 50cc is actually the qmb139 engine being misrepresented the reason for the division is in the United States most states have a 50cc engine law where 50cc or less don't require a motorcycle license but 51cc or more do. So gy6 ...cc was only for the engines that would require a motorcycle license in those states.
I grew up watching you guys
The Light only run when the engine runs. The CDI on that is an AC style one. Also the round black part on that spare engines that was major gear reduction
is a reverse unit.
If y'all ever have issues with wiring or anything, I'm open. I just pulled a 150 engine and put it in a little 50cc frame, so I recently just had to go through wiring myself. So stoked to see y'all finally work on a GY6 though. They're really good engines, and can make insane power with cvt tuning and a big bore kit. She spittin for real though 🔥🔥🔥
Carsandcameras:
Everyone: DuCaTi sWaP iT?!?!
I just bought one today they say it runs idk it's all together same exact one y'all got wow thanks for the video
I just got a new go cart for $30 and I got a new sprocket and chain it still needs brakes
ParKour Runners5 Nice find!!👍
Yes!! More GY6 content! My daughter has a GY6 powered hammerhead GTS150. My biggest problem with it is shifting. It just likes to grind. It’s not a bad machine for what it is. It’ll go around 35 mph. Just needs more ground clearance and a little more power
I have a 2017 kandi 150 it does 35 with two full adults frontwards reverse backup lights brake lights for headlights horn the whole works just like a car and they are damn good play toys you will love them
id never been much into go carts and really really not into cars, but you guys are responsible for my goal of fully fabricating my own reverse trike 48 CC road legal bike. Low to the ground, good suspension and one day a bigger motor around 60-100cc. Like one of those can am roadsters but made basically out of bike parts. Might use a big fat hill tire for the rear wheel.
hey guys the torque converter in those things use rollers in the front section and have specific weight to each roller. different weighted rollers mean different acceleration and top speed. also there are also performance cdi out there and different cam options that are pretty easy to get your hands on. also i don't think it has reverse, mine doesn't and i don't think they had different engines on that kart with reverse although i could be wrong. but there are different gy6 engines some have reverse i think but again am unsure. these engines were used in four wheelers and scooters, i think the four wheeler engines had reverse. last thing-have fun
Gy6 engines have a ton aftermarket parts for supper cheap big bore kits, nitrous, exhuast, “performance computer” with adjustable timeing. If you do keep the motor it should be alot of fun
Im experienced in gy6 engines. They are low quality engines but you can get some miles out of them by maintaining the service intervals. These are cheap copies of a old honda engine, they are mass manufactured in China. They usually come in 4 versions per CC, 2 shortblocks (10" wheels) and 2 longblocks (12" wheels), 1 version of each is marked with a "-J" or "P" in the engine number, the P or -J model has a little taller cylinder and head from what I've noticed. A normal problem are usually defective carburettor (diaphragm). They can also be very picky on the valve clearance (hard to start when warm etc). And if service intervals haven't been maintained they can blow, leaving you to replace the piston, cylinder and sometimes crank. A few times I had to replace the crank on the 125cc models since they started to knock (normal problem?). And in a few cases the stator has given up. Feel free to contact me incase you need any further information.
It's like Tony Stark and Hank Hill are working on gokarts!
GY6 150 + 50CC Moped done the swap several times now best swap ever if you can find a used GY6 150 for a decent price. power increase from 2HP to about 9HP
Hey, gy6 engine is realy good base for upgrading and geting nice hp figures
When testing wiring you can also use ohms (Ω). This will tell you how much resistance your wiring has and if you have a broken wire.
I used a 150 cc gy6 motor when i modded my honda ruckus Good motor
Hope to see you guys build the gy6. Lil bit different build compare it to another off road kart
Wish I'd have seen this video before I got rid of my gy6, couldn't get it to stay running and I never thought to hold down the breaks. Was on a similar go kart but it was a 1 seater
For my yerf dog gx150 when I hold down the brakes it won't turn over. So I don't think that's your problem but I could be wrong.
I watch you guys religiously
I have a Kandi Spyder 150, with me, my friend and a full tank of gas it was doing 32 miles per hour uphill. Combined weight with the weight of the kart included was around 1,300 pounds.
In general leave the black lead attached to ground and move the red lead around to check voltage levels. It is easier to spot voltage drops across connections and banged up wires..
pushing in bearings : get a fitting wrench socket for both sides and a piece of all tread with two nuts that fits through the square holes in the sockets and pull the bearing in by turning the nuts intoo eachother
can use the same method for getting the bearings out if you can get to it from both sides
I just got done re building one they pull great but you need to beef up the welds on front end where it connects to frame. Also get a performance cdi makes a big difference in power
Most GY6's are AC power so the wiring is backwards. Also you do not need to remove the chain tensioner to put the reverse gear on. Go power sports has a good install video for the reverse. I would recommend you guys do a Taida 232 GY6 upgrade. 25hp at the crank and just over 19hp at the wheel.
Finally a spider box now I can learn more about mine
Chris check out the Gy6 Buggy performance page on Facebook. Issac and JD can get you educated. Buggy Depo has everything you need to make the Spiderbox a beast
Started watching this in the house, but ended up finishing it in the garage
clean the cracked tank, use 2 part JB Weld to fill the crack, ride on.
Not the instant set.. the Good ole red and black tubes 24hr set
bansheemania the jb plastic weld works good too
I’ve grown up riding one of those Yerf dogs and recently owned one those exact models. That engine will go you can drift it in some grass the engine could use some more power but she hauls. They’re pretty durable overall but with that being said the wheel has rolled off while driving and my recent yerf dogs frame cracked after hitting a log. I love the steering you can handle the hell out of that big buggy and it feels amazing my favorite part on the buggy. Good luck guys hope all turns out well one of my favorite buggies. Oh and front tires might need an upgrade they will sometimes struggle to grip and turn.
Not saying you “should” do this, but if you want to disable the starter safety switch, you can do it in a way that it can easily be switched back n forth. Pull the rod of the switch out which is in the start position. Then drill a small hole through that rod of the switch switch right up next to the switch body. You can then insert a cotter pin in the hole which will keep the switch out which is in the start position and Bobs your uncle.
Anytime you want to use the normal safety position, just pull the pin.
If you take the starter apart, those little contacts on the inside have a spring behind them, and they're bad for those springs breaking. That's what happened to mine twice. I took the springs out of 2 ink pens and haven't had a problem since lol. Good luck!
Beef up the front end. I had one of those the spindles bend easily. And that center bracket where the A arms mount could use some reinforcement. Also more gussets on the top part of the roll cage
Gy6 are fun engines. They have a pretty big performance market. If your not happy with the acceleration or speed you can change weights in the cvt and different springs for the clutch too. But y’all def need to get a new performance Cdi box. And jets for the carb.
Hey there Ike, you can used the shifter on you semi auto 125 like a clutch. Play around with it you will see what I mean. Have fun men.
I just got a spiderbox the other day and put a warrior back half on it . Can't wait to drive it
Love the blue flames when Ike was revving the motor lol
I just got a yerf dog spiderbox that was sitting in a field for a decade. It was my wife's from when she was a teen ager.... After all new electronics and a carburetor the kart roared to life! I'm amazed that it was so easy to get running. Now I've had to tune the carb and currently have a 130 main jet and stock pilot. It is plenty fast with a tired old engine but it does backfire on decel. I need a larger pilot. All the ball joints are bad and most bushings are wallowed out. The shocks are bad the tie rods are bad the seat bets are shot, axel bearings are bad and the spindles are bent. But let me tell you. As is it rips doughnuts in grass. So much potential and so little parts. I'm sticking with the gy6 for mine but boring it to 160 or 170cc. I'm inspired to make a progress video now after learning about how popular these discontinued carts are and how easy it is to make a trail runner. ✌ good luck to all on your projects.
The way the cvt works is the engine runs the cvt (identical to a standard go cart cvt) then when the cvt spins fast enough the clutch grabs the drum which spins the output shaft
I say 50 horse motor with gears. Enhance the front suspension and get the rearend hooked up. Get bigger tires for better clearance. Good find Ike! Looking forward to Future vlogs on this machine.👏🏻👏🏻👏🏻👏🏻👍👍👍👍👍
The reason why the lights are like that because they hvae stators and the stators go bad in them and for the lights to work the stator needs to work for it to keep power going through the wireing harness
My moped as a gy6 motor with 80cc big bore kit, upgraded the cdi, also the carburetor.
Nice call doing a gy6. There are so many of these now and few good videos breaking them down.
You should build the motor flat side oko carb , big bore kit , racing clutch and variator racing cdi and all that good stuff trust me it would be a beast
My brother actually had this same cart but in blue, gas peddle stuck and he was going down a dirt road, had the choice to go head on with a car coming down the intersection or try to avoid it by drifting and he chose the drift. Ended up rolling it and bone was sticking out of his arm and rocks inside of his arm also. Ems said if he would have went head on it would have killed him. Also turns out there was a recall for the gas pedals sticking on these things.
Pine Sol 😱
@@dream2sea ya many years later he still has a pretty nasty scar from it.
Change out the ball joints on your 3206. There was a recall on them but you can still get parts. I am working on a reverse for mine as well as ball joint replacement.
Just bought one just like that last week for 300 and the guy had a Honda 396cc beside it I bought for 150 and it ran first pull no smoke and it sounds great just pull start though
Just finished restoring my daughter's helix 150 with the same engine it does 40 with me and my daughter on it alot of fun but mine has reverse but you can add a gearbox on to those pretty easily
Yerf Dog really liked those GY-6 engines. We have two Scouts that have GY-6's with reverse in them. Neither one runs right now, but when they did, they we're gutless and slow. The engine in better shape is going to be made to run again, and the other one is getting a Predator 301 swap, with torque converter and F-N-R transmission, and re-geared so that it'll at least keep up with our tractors to be used as a chase vehicle when moving equipment.
Make that puppy a 180cc the biggest most 150cc gy6 can be bored to without major case mods 232cc with mods an a8 cam to make the powerband 5000 rpm to8000 rpm and u might have changed the gears to a scooter gear ratio in the rear end so ... they make tons of different gears to fix it but you gotta start somewhere and most gy6 engines need the performance stater for better charging and spark with the ncy cdi with no rev limit (12000 rpm max) this cdi is the best when used with the high tension coil also made by ncy and makes the hottest spark some ppl that drag race these melt holes in pistons the gy6 is my shit love those lil engines!
I have had 2 or 3 gy6 motors I’m personally impressed with them
It needs a 250 2stroke 🤘
exactly what mine has in it..a rotax 249
That would be cool.
Yaaaassss
naa step it up even more, we need a banshee engine
2 strokes are for people that only last 2 strokes
The GY6 is a very common engine in Chinese based scooters. Chinese built based on a 1980s/90s Honda scooter engine. They come in 125/150/200/250cc. The 50cc is slightly different. Actually good engines if looked after but terribly underpowered and the materials used are cheap. There are tons of spares available (here in the UK) and simple to work on.
The way his face lights up every time an engine runs always makes me happy.
bmi karts ounce sold a axle upgrade kit that gave a larger axle with bearings wheel hubs and wheels. The wheels were bigger and the axle was longer and thicker. I then ordered a front spindle and wheel upgrade kit. This things was more like a side by side when it was done and went through anything you put it through. would never get stuck.
They're not bad, but if you're planning on doing like ATV wheel swap &going off roading be prepared if the wheels dig you're busting the case. We did ATV wheel swapped had to weld the front spindles back on & beef it up. Then put a 350 warrior motor on it after we broke the case. Then when that became an issue we just chopped the hole dog house out off a non vtec honda flipped it around, welded the rack & pinion. Welded to back of frame & sent it for about 2yrs til buddy sold it
Lights are like most 4 wheelers/scooters only come on while motor is running/turning over. Hard wire it to a switch & battery
just sold my gy6 buggy that I built from the ground up. with mods its not bad. I saved the head and put upgrade bits in the cvt. I think it would hit around 35. I know those things inside and out up side down and backwards
I had a 2 seater buggy with a gy6 150 engine in and a planetary reverse gear box on it. Moved really well with 2 people on up to about 35mph
Performance cdi coil exhaust and the red spring with the sliders in it and it would take off harder than the other yerf dog garenteed
It’s a spider box gx150. Front ball joints are prone to fail. The gy6 is 150cc and can be bored easily to 180. Top speed stock is like 28-30. Rear axle is crap tent to strip at the splines. Carb upgrade would be a 38mm makuni with a 130 jet. Btw it will rev to 9k no problem.
I have a gy6 50cc Chinese scooter with a 100cc bore kit. I’ve worked with theses a lot and performance parts are dirt cheap I highly suggest you mod that engine rather then swapping it. It’ll probably be cheaper. That looks like a gy6 150cc you can buy a 171cc bore kit for pretty cheap along with a performance camshaft if you look into upgrading it a lot.
They are no speed demons, but when the cvt is properly tuned, they are fun to ride because they rev like crazy. You should look at RBG's Zircon videos, it's pretty amazing where it will bring you.
I just picked up the same kart for $300 too. Putting a 200cc atv motor in it
Jack, I'm working with what I got. Working with a "ramen noodle a night budget". Most of my money goes to my son's cancer medical bills.
I put a ninja 250 on mine check my profile for pics
@Jack Juliano that's why I'm working with what I got
Stephen Sloan you know what helps pay medical bills??? METH. Meth cures cancer. Go get some meth
that particular type of CVT is very common on scooters...ive been working on scooters and small engines better part of 30 years...those are fun to play with...different weights in your front variator will change things like takeoff speed....light weights will keep you in a lower range then say heavier weights will...with that heavy cart tho im not sure what effect it will have ...unlike the scooters...i currently own a 2003 yamaha zuma...i have a polini performance CVT in mine...fun stuff guys...you guys do stuff like me and my buddies tried doing years ago....
YESS!
Glad to see u guys back to the basics.
One thing I learned from this engine is if you don't fully tighten the flywheel all the way it will destroy the stator and the flywheel
Guys! The gy6 150 on my Yerf Dog is a little beast. These units are cheap to build and can really push. Mine has $200 of upgrades, but the best bang for the buck is changing out the stock variator roller weights to 10 gram sliders ($24).
Gy6 scooter engine upgrade part is plenty.. stock gy6 is 125-150cc.. can be bored to 180cc ish safely provided u do upgrade the cylinder head and bigger camshaft...
Pulley and roller kit plenty on ebay... Heck even diy injection plug n play kit also readily available
But... I would say, u can easily plonk in japan k-car 660cc turbocharged 3cylinder engine complete with gearbox and such easily
*CarsandCameras* I predict a 670cc swap, do they make alot of performance upgrades for those? If it were mine I would find a late 80's - early 90's Polaris Trail Boss 250cc 2 stroke as they make 25-30hp and have a fwd/neutral/reverse gearbox and torque converter style clutch all built in to a complete compact unit. They are on Craigslist all the time from $200-$800 and are extremely easy to work on. Excellent videos, I watch them all.
We have 2 of those, they have plenty of power and speed when running correctly.... Unfortunately they have a very finicky carb and ignition system, any small problem and they start hard or not at all and leave you stranded if you take them into the woods. 48-55 mph with a couple of big guys on it. FYI, if you throw those bearings in the freezer for a couple hours they will slip right in without beating on them.
Big bore kit, I’ve seen stroker cranks and a big cam, throw all of the go fast parts at the gy6 before you decide to swap it
Thank you!!!! Finally!! I just rebuilt one and was curious if you goes would finally get one.
Thanks for this channel. You guys rock. You guys inspired me to start tinkering again. I'm putting the motor/trans from a Honda 110 3 wheeler into a mower frame with live axle right now because of this channel
HAZAMANIA RUNNINWILD 👏🏻👏🏻👏🏻👍🏻
I’m currently in the process of putting a 420 on mine. This Yerf dog is called the GX150. They came in orange and blue. That’s the only colors I’ve seen them in. Model 3203 i think. Buggy Depot has many parts and info on this particular kart. Good look and I can’t wait to see further vids
I picked up one of these two years ago for 125. Got home rebuilt some of the wire harness and started it up.
You guys always find good deals, I have been trying to find a good deal but around here always trashy ones that want a fortune. They sell stuff no motor and busted frames for 500.00 the ones that don't look trashed they want 900.00. I hope to one day find a good one like you guys. Keep up with the educational videos.
Brings me back to my childhood thanks for the video
