[@Mayhemspent]

"Opened her up and smoothed her out"... Id buy that tshirt. ;)

[@ChrisPBacon-uo4qk]

LoL

[@BigD1395]

I really enjoy watching you guys do mods to these small engines. None of which I've ever tried. Now however if I was so enclined to do so, I'd feel more comfortable doing them. Keep up the fantastic informative/educational help video's!!! 😊

[@Kazooboi23]

Love the little transitions you do when you go places

[@DracolegacyOfficial]

thank you for having proper audio levels during the voice over. i dont know why so many people have trouble with that part but you nailed it.

[@FatsharkFun]

Wow! Go Power Sports should really bundle all these engine parts together to make an ultimate performance package! I would love something like this for my go kart

[@slowmissouri205]

I see channels like this installing the kits, but I totally agree they should make signature kits designed and tested by them. It would be a great partnership.

[@blader2themax10]

This new build style where we get to watch how you do everything is AWESOME! The explanation and speed were perfect. Hope to see more detailed builds like this!

[@kingbryant5673]

I love the voice over it allows you guys to keep working without stopping every 2 seconds

[@greenwizard2000]

I realy like the post-commentary. It gives more time to thevideos and makes the building parts more exiting.

[@BadHaddy]

As an engine builder.. you need to know that the aluminum rod will expand when it heats up, about twice as much as a steel rod. Measure your deck clearance at TDC after you assemble everything to make sure the piston wont smack into the head. I'm sure the maker of the rod will have a recommendation, but on the engines I build, aluminum rods usually need .060 to survive... CC your head, and piston, so you can calculate your compression. Will let you know how much room you have to wiggle.

[@DanielFeliciano-h5n]

How would I do this? Would I adjust the valvelash to a different spec? Please get back to me as I’m interested in making a high rpm engine build

[@addicted2fuel]

I can't wait to see this engine running. Great video guys

[@heathfiedler]

Mini Bike Addict216 yeah I'm stoked to see if they hit 90 or better. Here's to hoping!

[@bigwhane8603]

Dude this is the nicest build yet

[@GroveDaLord]

I dig the editing cuts you guys keep putting out better and better content 👌🏼👌🏼 love you two!

[@MegaFPVFlyer]

Y'all are really stepping up your game with the transitions between shots.

[@notdatboileroy9602]

Building my first kart! Thanks for the inspiration guys.

[@robburdack4361]

Isaac,s girlfriend just giggled a little at the end of the porting section

[@papafranku1867]

What time

[@robburdack4361]

if you cant work it out you probably dont need to know LOL

[@papafranku1867]

rob burdack no I'm just lazy

[@skrewylewy3259]

fingers does usually open her up hahahaha

[@Ratkill9000]

skrewy lewy No joke so true

[@GOTM1776]

Hey guys, big fan. Love your videos. Just want to point out that there are dramatic differences on torque specs with wet or dry bolt threads. Torque specs are generally dry unless specified. If you use provided torque specs, it is intended for dry threads, no lube or thread lock. If you use those specs with wet (lubricated or thread lock) threads, you can over torque the threads. Keep making great videos. You've brought life back to my love for go karts.

[@calebhaynie7511]

Thanks for all the great videos Ike and john will always watch forever.

[@resultsads]

Looks like one wicked predator. Can't wait to hear the rpm hit 9k!

[@berniemcpartland254]

GREAT TIP for beginners..."EXAUST ONLY" Love it.

[@Mr17riddog]

That little crankshaft is so cute lol

[@randymang1]

Now this is the kinda videos I really like to see you guys doing!! Great work so far

[@Crispy_22]

I cant believe the amazing work that comes from your channel. Keep it up guys

[@romka_ind]

That exhaust port polishing with a finger, just gold.

[@kiiiisu]

ur vids has been getting better and better i think this is the time to not change a thing anymore, i like!

[@El_Chompo]

that exhaust port is beautiful :O can't wait to see her rip

[@LiveModz]

So happy this video is out! Love all your videos both of you! Thanks for the best entertainment for me and much more:)

[@kita17n]

great flow work on the 212 head !!!!!!!!!!

[@TheBarnacleBlimp]

That was a great goody box from go power sports. And the con for was a thing of beauty

[@nickzona2491]

You're editing skills have gotten so good!! I've been watching you videos to the end because you have content, and an interesting video. Keep it up! 😃

[@SCARNEDGE]

Still onpoint with your transitions store to shop 645. Lovin it.

[@Aleks_Z]

This was very satisfying to watch! Thank You for Your awesome content!

[@nicholasschmidt4014]

I have been waiting 5 hours for this video

[@calebhaynie7511]

Nick Schmidt me to

[@Hermiwalle]

[@theskinny111]

Fave episode yet! Thanks guys!

[@cobravello453]

2:51 when the music started and jon's voiceover kicked in i thought you had completely lost your mind and were rapping :D :D

[@RageForSeven]

dude..the memes is strong with that one..especially the whole exhaust port section!!!

[@jettables9470]

The engine is looking nice guys. Keep up the good work

[@jblhunter]

I can’t wait a week for the next episode!!!

[@brokecountry3965]

ON A PREDATOR!!!.... HELL YEAH! Go boys go! Good luck. You guys are on somthin here!

[@tritclips3304]

Been watching for 2/3 years love the vids

[@mingusbreeze]

Thanks guys looks like a fun build.

[@bighomieJ5X]

That clutch tho ...😎😁 ,its about time...

[@jeepcollector91]

If you ever decide to build another amphibious go-kart or maybe a Predator powered paddle-wheeler/stern-wheeler boat I might be willing to give you my 1974 Boston Whaler 13' boat (w/title) if you would use it for the channel. Could become a cool little river boat to travel from Washington, NC to Greenville, NC and back? Just a thought...

[@megantripp9520]

thats my area n.c.

[@markferris8079]

so John leaves for the day, and comes back to end the show just when it's getting good, that sux!!

[@bandeboyz2205]

We use the exact chain and clutch on the mini cup. I love the videos. Gonna run out of data watching them

[@kenwinston2245]

9 grand out of a one banger . . . Sounds wild can't wait to see

[@edam-gw9sw]

Its cool to see all these youtubers from around my area. We need a mr.beast and c&c collab

[@ps4racinggames472]

I love the transitions

[@mitchellscripter587]

just saying, i love the camera mounts for the montage

[@frogglidd1951]

I enjoy watching your videos hopefully you record. Hopefully we see you guys can video the older rigs that you're going to go see this weekend that be cool

[@baileyvolkert]

Impressive Engineering on that rod

[@DeliciousDeBlair]

I've never seen rolls of sandpaper like that! Definitely would be MIGHTY handy!

[@jeepcollector91]

@ 13:20 that just doesn't look right... LOL

[@Lonwolf4019]

JeepCollector91 neither looks or sounds right hahah

[@mylostwife5230]

That Shit Hurted

[@ryanwelch64]

JeepCollector91 😂

[@Shoottokillcelebrities]

Prison style polishing

[@chucklemmensen]

he opened her up and smoothed her out

[@MillennialRebelion]

Cant wait to see it run. Im so excited.

[@RaztechPowersports]

Fingering the Exhaust port... pretty good idea lol

[@quevicular]

Awesome, this will be great to watch. You may even get 88 if you can turn some serious rpm

[@isaiahmcwhorter7907]

Best channel EVA!!!!

[@macbilling6410]

Looking forward to seeing the end project.

[@iMatthewWilliams]

Lol how did it take this long for you guys to get a torque wrench

[@user-qx7tm5df8j]

6:33

[@cskalle1213]

dont you get it ? ill be fine.. and then some broken engineblocks later they changed mind xD

[@matteedstrom]

They still don't have one. They bought 12-point sockets^^

[@cskalle1213]

me and my brother dont have on and he just bought a cylinder for his 2stroke moped 1 week ago now its lost its power

[@gavincline3581]

you did a top end rebuild without a torque wrench, dumb fucks

[@Greybuiltracing]

Bravo 👏 👏 👏 nicely done guys ! Will be using this as a reference point . Ty

[@The_Lurker___]

Finger banged to perfection that exhaust port..

[@keeganhurren9931]

That is one hell of a engine

[@fiveowen]

We want more videos weeklyyyyyyy! Please I’m needing more vids

[@barris1233]

*IT'S HEAD TIME*

[@StephenButlerOne]

Wow, stage 47.20. I love it.

[@gekquad116]

Like the Voice over!

[@peterdebad1]

Like kids on Christmas morning!! Enjoy!!

[@maklarus]

well sayd Get INN there 13:16 and the movement Priceless i see you got a lot of practise

[@juantabby4787]

Much improved video production

[@bjlracer1380]

Can't wait to see the finished product, and how long it can be beat on before it's toast.

[@cyborgs_gaming4859]

Hey guys love your work from Australia

[@DreaminginWaves]

Great video!

[@jeffreystroman2811]

I just got done tearing into a 5.5 hp engine to get a free log splitter running so i had to watch this. One thought, I was told once that torque specs are only accurate for clean dry threads, so any substance from never seize to silicone to motor oil throws off the accuracy of a torque wrench. Not sure how much, probably a whole video worth of research here but thought I'd chime in when i saw y'all lube the threads of the one bolt you wanted to be sure about torque-ing down.

[@lanemccabe4832]

I like the idea its looking good

[@ChrisPBacon-uo4qk]

Awesome, this thing rocks!!!!! :)

[@danhard8440]

kind of funny seeing 2 big guys working on a little engine and even one of them going oowww lol

[@legowarriorsadventure3613]

I have a racing buggy that stock where the governor makes 6.5 hp with a stage 1 or 2 kit and without the governor it will do burnouts, Monos and it also makes 15 to 16 hp and 9000-10000 rpm with no governor

[@builtcountry2985]

Love these vids I use a lot of ideas from here

[@kovamaps9379]

i like the start of the video :D

[@TrojanHorse1959]

Great video guys! Ike, instead of wrapping sandpaper around your finger you can get various grits of flap wheels for your die grinder & you can carefully cut a slit into a piece of 1/4" steel rod and use pieces of roll sandpaper to make a polishing flap wheel. It sure beats using your finger...unless you just really enjoy that kind of thing... ;)

[@herbienbrian2]

Yes back to the 212's

[@MrNosajwhitey]

Looking forward to the next video

[@andrewforbes4817]

This thing is going to be awesome

[@sherm31522]

It would be awesome to see you guys build a big offroad kart with huge tires on the front and rear.

[@lyleklemm7408]

Awesome video

[@dodgeme1986truck]

If you are going to shave the head with sand paper get the glue back stuff and stick it to a piece of glass and hand sand. This technique leaves the best/perfectly flat mating surfaces you need at those rpms. Also you really should polish the exhaust runner as well as the combustion chamber as it will reduce the heat that transfers into the head during and after combustion which may cause your valve seats to eventually fail at those rpms not to mention mess with your valve lash settings (best way to lash valves is with the engine at operating temperature too).

[@andrewashley1548]

More ct70s please?!! Enjoy the videos😄

[@beerandhorsepower3018]

Oh boy I been waiting for this!

[@snoops7942]

great video!

[@heathfiedler]

Love watching you guys, really wish I had the time to do what you guys do. Seen an off road cart here like the redone you guys have for 200 but they said it needs lots of work. If your looking for more carts ill pass it along to you guys. Good luck with this build I nearly cried when Isaac's motor blew on the other cart. Sorry for the loss.

[@sin4will]

13:20 Ike just proceeds to finger blast the exhaust port on that poor little head.... and he didn’t even ask for consent 😑 No but for real! Love your videos guys! Keep up the good content! I know this was made like 2 years ago, but the new content is so great too! 😂

[@thebiggsfix6987]

Great job great vids 👍

[@kennydidntdie6370]

I was excited for a full engine build in one video it woukd of been really nice but oh well

[@3370603]

10:34 Ouch my eye. !😳😜🤣😂 cool job u guys enjoy ur your videos any chance with all the videos you've made you could put together a blooper video of some kind ?? That would be funny im sure . we all have them days

[@dano2644]

I used the polish wheel and compound from my Dremel to polish. That makes for a mirror finish!

[@dano2644]

camjamsdad correct. That's all I polished was the exhaust.

[@joshuahighfield37]

You really did polish that exhaust port good with you finger Lol

[@alexdtay]

The original Lucas engine oil additive is a GREAT engine assembly lube me and several friends have built some very high horsepower twin turbo LS motors and never had a problem. It has awesome sticktivity and stays on the parts till you fire it up

[@javondagoat9145]

They just hit a million

[@neutraldown6271]

“You get in there and smooth it out” classic

[@BIllMcCambridge]

Great explaination IKEA rough intake port for maximum turbulence keeps fuel in suspension. Smooooth exhaust for maximum velocity and scavenge effect during over lap. Please explain compression release? Great job can't wait for next one?!
