- เผยแพร่เมื่อ 15 มิ.ย. 2024
- We finish installing a Predator 420cc stage 2 performance kit from Go Power Sports, which includes a high performance cam, billet flywheel, dual valve springs, and a billet rod. We also install a carb jet, air filter, and header on this gx390 clone. This built 420cc engine is LOUD! It's probably the loudest small engine we've ever run to date.
Thanks for Watching!

Since when did this operation become a high end production? A torque wrench? You guys have changed! 👍
That is probably the first time I have seen them use a torque wrench!
It'll Be fine
Sponsors... Gotta do it right to get paid...
GPS torque wrench available in the discription below
They've used them before 😂😂
You guys just keep getting better.
How far you've come since the drift trike videos you hooked me on. Love it.
Can't wait to see it in the golf cart ;) you said it in the last episode....
JSMachineWorks it’s in the vid

Anyone else notice he was tightening the exhaust stud?
Yes I did
He tightened two nuts together to make a “bolt head”
@Noah Batterson
THEN he screwed the stud in further.
@@noahbatterson8591 And then he preceded to "tighten" the stud instead of loosening it.
Reverse thread
It seems like we've been begging you guys to build a golf cart for years. I'm so glad that it's finally time.
Ya got to remember old school ! Lock the crank , add compressed air to the plug hole and use a lever type spring tool .No seal , add oil . The air pressure holds the valves closed and in place while spring are removed an replaced . Ike's boss must know this one ! Good videos Guys .
8:55 Yeah, things tend to be hard to take off when you're tightening them.
Yes it was
Isaac it'll be fine I am guessing you just got thrown off because you were on the other side of the engine and accidentally tightened. Hopefully no chinese threads were damaged and no helicoils were purchased 😅
Eh, who hasn’t done that......
Thank you again. Great uploads, love following you guys.
Hope this grows and grows!!!
You guys make my Mondays and Wednesdays so much brighter :)
I just swapped a stock 212 on my craftsman snowblower and it makes more power then the old 9.5 horse briggs and is much quieter also. Now i see why you guys love these engines

*CarsandCameras* She's a thumper! Can't wait to see it in a street legal golf cart! Glad they legalized it in your town. Whenever I go to a nearby great lakes (Michigan) beach town I always see golf carts rocking around the streets, I always found it unfair those folks can do it at their liesure while around here we would be ticketed and possibly have the cart confiscated. Not sure on that, but I may try and push my luck 😁. On a side note, I have an old 1988 Polaris Trail Boss 250R 2wd and figured it would interest you to know those 250 2 strokers make from 20-30hp and have an excellent torque converter and fwd/neutral/rev gearbox-so keep your eye out for a used cheap one. Thank you for the excellent videos.
Where im at in michigan as long as you have one of those orange triangles that the tractors use you can run them on the road
Guys,the quality of your vids are getting better and better!
A trick I have used for compressing springs... zip ties. Keep the pressure evenly spaced out by using 3-4 ties and tighten them each a little at a time. Your mileage may vary epending on the weight rating/stiffness of the spring.
Top 10 favorite channels! Great videos!!!
Johnny Is the MAN I just wish I still had the drive John has . The boy loves his ENGINES
That thing sounds soooooo nice! Can't wait to see it power that golf cart!
You guys give me so much inspiration. Also i have a tricked out 420cc drag mini bike
Cool video guys! ,,,went through 2 ,,,40 series TC on my 420 stage 2 build,,that cam is something else. With great power comes great responsibility!!
Awesome video guys. Can’t wait for the next one.
I've seen a couple things here lately in the background can't wait. Also motor looking and sounds sweet ( I'm sure way better in person)
Can't wait for the golf cart! Could definitely use a lift, big tires, a transmission and a light bar! Sponsors do your thing!
I love this channel keep up the Builds guys
Love seeing your guys Duralast tools!! I'm a big advocate. "Built to last, Duralast"
I used to have a valve spring compressor tool for small engines, that was very compact, and the head did not have to be removed.
Thank you go power sports
A street legal golf cart. Fantastic!
Dang boys gettin in it again.
What a beast keep up the good work lads from🇬🇧
I have a big block Subaru 300cc that I put on a garden tractor. It was a factory starter delete, and had a plate in, but I took it off and put some mesh there for better cooling because the engine kept overheating and boiling the gas in the metal tank. I also added a fan, and drilled holes in the shroud.
That thing is awesome!
Nice video guys, that thing sounds mean! Can’t wait to see what it’s on
Anyone notice the golf cart parked outside. Next project?
thats what the motor is for lol
Yep
time stamp?
They said last video that it was for a golf cart, the town they are in just made legal to use on the streets.
Yeah they did say that. Plus it looked like a piece of junk
Sound like you guys are going to have the fastest golf cart around 🏎
I love the vid I’ve have Ben waiting for this and I want to no were is the dragster man ether way I love this channel
awsome vid ike and john
I wanna see that old truck done! Love them old trucks!
I use zip ties to compress the spring, then I put everything back together and cut them. Works like a charm every time.
Saw a quick glance at the golf cart when Ike was bring out the motor
Flames make my day!
I'm excited for the golf cart. Gonna turn some heads driving down the road with a golf cart that loud.
I was just looking on your channel wondering when your next video will be, sweet!
I just got my 150 carter talon go kart converted to 420cc last night. It took about 2 weeks because I had to wait on shipping and I had to modify the frame for clearance but I was able to use the original axle by using a long jackshaft on pillow blocks and the chain actually runs underneath the engine rather than next to it
Bigfoot And Bananaman got much clearance beneath the sprocket??
Yes I have the sprocket behind the engine and the chain goes underneath the engine where the sprocket on the axle is
Awesome build keep it up
I see a lot of big boxes over by the truck 😉 Cant wait to see the truck progress hopefully soon. Wish I had some garage space and some extra cash to buy a go kart to tinker with. Would love to build an engine as well. Someday...
That was freaking awesome guys, put it in the chopper bike, Ooooh yeeeah guys.
Its going to be one heck of a hotrod golf cart :)
nice, cant wait to see what it gets put on, thinkin old cushman scooter
They are puting it on a street legal golf kart
Did you ever get that put on? I would love to see your build. I am building a Cushman package kar. Well restoring anyway. it had an M9 but only had 30lbs compression. So I went to find out how much rebuild was and said screw that!
Look at that cool bed shaker
I cant wait to see what thats going in .
You are getting close to 600k subs.
I love engine builds
The murray desurves this engine
Sounds good👍👍👍👍
Wow that is very nice
Sounds gr8
That sounded mean. Its a Banger for sure!
BADASS engine!
Check the yellow cam card I believe i saw lash adjustment is done cold...lol nice video!! Keep em coming boys.
Ike, with the valve spring tool you couldn’t get to work. Put a hose clamp around the arms and tighten it down. It will keep the arms from spreading when you start compressing the spring. This hose clamp trick also helps with gear and pulley pullers to keep the arms from slipping off in shallow pulleys.
Make a ricer golf cart! I think it would be funny to see a slammed purple golf cart with cambered wheels and I’ve always wondered if you could use a 1 inch universal joint as a CV joint for rear wheels that way you can get negative camber.
Love the vids, can’t wait to see the finished golf cart!
Nice!
And thats with a mild cam.
You should be able to add compressed air to the cylinder through the spark plug hole at TDC (kinda like a backwards compression tester set up) and it will hold the valves shut in order to change the springs without pulling the head off...just a little tip from your old uncle Ed
Lol mine does the same thing... I just finished my stage 2 kit and got the carb almost tuned and when I rev it I shoot flames a good 2 ft. I thought about welding another piece to my exhaust and doing a fish tail tip to make it look cool and to add a little extra length to the exhaust.
Ike. Ace mechanic and motor counter weight lol nice video guys .put that motor on rat rod and hold on. !
love your build !!!! cant wait to see the cart !!! edbonjovi
He finished the sentences with a yep yep yep 😂😂 love the vids
Cool!! That should be on a motorcycle.
Imma put this engine on a micsrgi seattle ss
This is awsom!!!!!!!!!!!
You can buy apart that attaches to an air compressor and it keeps the valves shut I used it on my mates s2000
You guys sure do things the hard way. Get a simple aviation type valve spring tool! pack cylinder with some rope. Depress the springs and remove the keepers!
Ike, on the valve spring tool. Have you ever seen if you could use a spring compression tool for the spring inside the s10 pickup and blazer door. The one that likes to shoot out like a rocket when you do door pin bushings
LOVE IT
Awesome!
You can add air, you can add fuel, you can get exhaust flow, you can out a big cam in it, BUT without compression all you got is sound and few extra horses but you need to calculate compression ratio, dome piston, or small chamber head to take advantage of the other stuff. You have just changed parts that isn't building a engine BUT! I know y'all don't have much time on your hands but still cool videos
Drill a hole through the side of the head on the Allen head bolts holding your exhaust header on and run a wire through both bolts and twist the wire together. That will prevent your exhaust bolts from vibrating loose 👍
I installed 36lb. springs, upgraded retainers and keepers, SS valves, 3 angle valve job, CM pushrods, retained the balance shaft as I can't justify the money to have the rotating assembly balanced for a golf cart, forged piston .010 out of the hole/+.040 billet rod, and went with the Torque+ cam as I have very little flat land to ride. Oddly enough, I can't discern noticeable difference than my 420 running under no load. Thought that .275 cam would roughen the idle more.
Too cold @ 17 degrees outside to open the door and fire it up or I would.
Good video
I gotta put one of these on my 85' Honda Gyro
Sounds Guud!!
Gona be awesome in that golf cart out there😉😎
Nice its guna fly!!
Better get some fuzzy dice for the golf cart
When you guys first got the engine fired up that's basically your intro to all your videos
I can also tell you all some ways to set your chassis up some ya know like how to get it to roll as freely as possible. Lil tricks you can do to your bearings to help free up some friction.
Sweet let’s gooo boys!!!
Another good way to make sure no metal gets in the engine when your taping it is to use a shop vacuum on it while your taping to suck up the metal as your doing it
Hi love the video
Working on my 212 and needed a break lol
John now gets a standard torque setting for all installations.
Take a old spark plug break the glass off remove the internals and weld a air fitting to the back of the plug threads. When you screw the new device in add/connect an air hose to the new fitting, it will keep the valves seated and allow you to do the work!
Yall should do a project with a lifan engine that would be exciting to see
FWIW, the paperwork for your cam specifies .003" lash intake and exhaust.
Did you try clamping or zip ties around the arms on that other tool?
You can make good gaskets from cereal box type cardboard and permatex red. My lawnmower horizontal conversion on my kart never leaked.
the rocker arm gap is set when cold because when the engine heats up the metal expands and closes the gap up
What ever it is it will have some power
Adjust valves hot...cold adjustment is fine to warm it up. Once warm, readjust. Unless engine runs and stays cold your adjustment will change causing problems. Metal expands...
It's going on the golf cart.
first time i helped doing valve springs with my mate we were struggling, my dad came in and smacked them with a bit of pipe and a hammer and did the lot in under 5 mins lol we got showen haha
