2X Factory Output! Predator 670cc Performance Build
Today I tear apart my 670cc Vtwin and double the factory output! I install a cam, dual flat-slide carburetors, push rods, exhaust, billet parts and much more. This one's going to RIP!

Hope yall enjoyed this video! I Install billet rods and flywheel here: kzhead.info/sun/mbSnpp1peaaCaH0/bejne.html FIRST DRIVE HERE: kzhead.info/sun/gdpymbSbkZeYaKc/bejne.html **I have to correct myself, thicker oil is not always better. Subscribe for more epic videos. BTW This video was expensive and NOT Sponsored!
That thing looks and sounds awesome! Good work!
That makes it even better, stay golden pony boy...
I sent you 10 bucks for this video brotha
Awesome video bud😎😎🇬🇧🇬🇧🇺🇸🇺🇸
Dude put the engine in a go-kart 🤭
I must say I am impressed by the quality of this video and your commentary. No needless rambling and the thick oil comment gave me a laugh. Well done man
That would be bad ass
This comment got the subscribe button hit before the video started
So you see after he crashed the cart with the 670cc, he realized the problem, there wasn’t enough power to drift away from the house
😂😂
how does it compare to a rotax 600 or 800-850 etc? My yz-250 pushed 48hp stock and my OMC sled motor even more. Are you runnihnig xd-100 etec oil or amsoil dominator? I got my sled motors, yz-250 and kohler toro mower on xd-100 amsoil dominator. i just bought 6 gallons quicksilver synthetic TCW3 to fill my 8v92 detroit 2 stroke from walmart and its way cleaner than rotella. The synt tcw3 has high film strength and runs and burns cleaner but its little more pricey!
@@jlo13800 Can't compare because you're trying to compare an industrial v twin 4 stroke to a single cylinder 2 stroke
he will have problems with valves ....just add a turbo without changing
@@jlo13800 thats a performance built racing engine comapred to a fucking lawn mower engine.
Here is a trick you can do for more power Advance the spark. I saw two magneto and that might have an adjustment. 1 use a rotary file, cut slots into the mount hole and elongate the mount holes. Use a large washer afterwards to lock it down and keep tensions 2 not sure if the flywheel has a key. If it does, grind the key to half the thickness so you can advance the spark by rotating the flywheel on the crank 3 if you have a small airport nearby, pickup some blue gasoline. When I did it was 108 octane high lead but I think it is 100 octane low lead now. Not quite sure. 4 mill port and polish the heads. Possible a thinner gasket. Take a 4 inch bolt, sandwich some coarse steel wool between two large washers, and get a drill and polish away. Remember to blow the doors off everyone around you. Vroooooom Just some old tricks to get more power
Идиотизм!😅
I did this on my 99 Miata. I have been running a 5-degree advance for about 10k miles with no issues, it definitely had a small but noticeable bump in power.
Old School tricks for sure!
Fyi, that is called timing gain or delay. The carburetor can alter time if he sets a higher idle with slow time it will synchronize at the high rpms. Dragsters have used this over 50 years.
I’d love to see that motor run through a 5 or 6 spd gearbox
How about 4 of them? Bolted inline?
I've seen some people take old atv or dirt bike bottom ends modifinging them into gear boxes
NavalhaDeOuro you can never have enough gears
@@colbywentzel Sounds like pretty serious ordeal amazing what the human mind is capable of when not consumed by drugs .
@@zragevii4705 hell yeah
We need more young men like you in this world! Gearhead for life!
TTime685 100% agree with your comment !! Using social platforms for pure American ingenuity rather than mindless narcissism!! Great work kid!!
u r correct.
Whoa - can you imagine this engine in one of those old Citroen 2CV's? Crazy.
Very nice build! However, I would put the front cover back on as it's responsible for directing the air from the fan on the flywheel up onto the cylinders. Thus cooling them
I used to run a honda twin on a pulling tractor and we loved it. We made a custom intake and manifold ourselves, milled the heads as much as possible, stroked the crank .60, and ran stock rods and cam, it turned 6k to 7k rpm easy and had tons of torque. I've been wanting to build a preditor the same way and now that I know you can get a cam and everything, should be awesome.
Dude, you're killin it with awesome uploads!! Keep up the great content!👌
6:49 I agree. Hey GREAT JOB on that engine!
great to see young people people this. Fewer and fewer every generation. Im 33 and after never having a garage or really my own place, I just started to get space and tool to finally be build and fabricate.
The sticking throttle linkage line was a good reference. Glad to see your doing better Vasily!
The original hole for the govenor shaft I would recommend tapping for a fitting same with both valve covers. The reason for this is to keep the oil in the block and so it doesnt build up in the heads. I know it's more prone for the single cylinder engines like the 212 because at 7000+ rpm you dont wanna spin a rod bearing. It helps the oil flow back into the block and not build up in the head.
Just don't be turning it to fast without at minimum a billet flywheel. Don't want to see you with shrapnel wounds. As always, stay safe and have fun!
It’s happened to me
“The thicker the better, just like women “😂😂😂 epic dude lol 😝 that made me subscribe
Been proven false. Higher viscosity means increased drag also. Engine with oil cooler that can keep tempsbelow 300F should be happiest with SAE 30 or 40. BTDT. (If you really need THICK, why not go for synthetic grease?)
Thiccer**
@@jacquesblaque7728I bow in gratitude to your analogy relating to viscosity and drag. Profound! So im mulling over your "400 footer into the center field stands" statement and Im thinking...all oil is slippery, but viscosity options when applied to protecting a gasoline engine makes the oil (for lack of a better alphabetical grouping) tunable to the demands put on the parts,with the dissipation of excessive temperature being job 1.Then all the other possibilities that manipulating the drag of motor oil as it travels over various parts Can only bring more positive options.The 100 foot aisle of oil choices suddenly makes ridiculously excessive levels of sense .Thankyou! I think...
Had to throw in the "j/k" so he won't get any back lash from those non-thicker women😂😂😂
くーんEJ legend has it vasily likes a woman with thighs and ass... the thicker the better lol
Its awesome what can be done with such an affordable engine like this. Great job on the build .
I raced small capacity 4 stroke twins in the 80's and these carbs a re very similar to the Mikuni units we used. Here's something to try, put a connecting pipe between the two inlet stubs and then balance the carbs so they flow exactly the same, when balanced connect the new pipe and test the difference. Also this engine would almost certainly respond well to a reverse cone megaphone exhaust, a little experimentation could give good results. Nice build and none of this is criticism just passing on years of building em.
Harley Davidson + Nascar = This engine sound.
you could make that engine run so much better just by simply installing an air box ! It helps synchronize carboration .
Nun more satisfying than hearing those head bolts break free
“remove the stock linkages as they have been known for sticking” noted.
im interested
pls help me to modefied to my engine..
@@seamanvlogs1998 no
Dude that engine is a monster now! You got it breathing straight fire, it is going to rip lol
I still love watching some of your older videos this blew me away when you built this I watch you on my TV then I come to my phone to leave comments you are a beast bro 💪🏾💪🏾♥️👍🏽👍🏽👍🏽👍🏽😎👊🏽
Malaysian 135cc liquid coolant bike can push to 60hp . After plenty of modification ,the cc increased from 135cc to aroud 250cc
Oh no it’s been made even faster to crash into a wall faster lol 😂 stay safe looks amazing and hope your all ok 🙏
"It's better to burn out, than fade away"
A good video on youtube recommended videos, I do not see that every day... Good work dude! new sub, waiting to see you put that beast in the off road kart!
The stock engine intake does not look bad at all, like to try a big single carb on one. Just have to fabricate the adaptor.
I admire you man Such a beautiful engine You made it look powerful
this kid; hes amazing! what a bright future hes looking at
Nah. Many of us who were once bright up and coming people like him got that beat out of us the hard way by life. After he burns up a few years of his life and rare skills making someone else, who doesn't give half a shit about him rich, while he gets nothing for it, it will take the want to pursue this stuff in any meaningful way right out of him. Ask me how I know! I made enough narcissistic fuckwit losers rich at my own youthful expenses before I wised up and walked away from ever doing this stuff for anyone but myself, just like countless other garage wizards now in hiding.
And avoid any further activities that have high potential for compound fractures. Ive managed to blow out my collarbones till they just flat refused to fuse anymore.had to get em wrapped and pinned and when I had an MRI ,the pins heated up and burned through my skin and sparks started bouncing all over the place. The technician turned on the PA and I heard through the speakers.."Sir, are you smoking in there?" Yup, by now the bib i was wearing was smoldering pretty well " yes ma'am, It appears I Am. It goes along with my being on fire! " Pure excitement! . My attorney says catching on fire during an MRI ... Priceless!
Toosuna Kabooma. DAMN
Good video. Very informative and entertaining. I managed to laugh a bit at the joke. Keep in mind that I did damage a car's engine by using heavy weight oil. The engine just didn't get hot enough to flow the thicker oil correctly which resulted in rod knock. One of my many lessons in life to not always pay attention to what you read on forums.
Dang great info. I choose it because this thing gets hecka hot. I'm was also planning on running the same oil on my daily. If I ever turbo it
Great video this thing sounds like a 1970 shovel head with small pipes LOVE IT
Please twin supercharge this. I want to see someone take this beast to the max. Love the video bro👍
That thing's going to be a beast. Good job!!
When torquing the oil pan/ "side cover", you should always start with the bolts closest to the middle then work your way further out. Just FYI. Cool vid.
I know it's a year old, but explain why for the noobs
@@jeremym8748 the mating surfaces will line up straighter and will make a better seal. All torque sequences start in the middle of the part, whether its a head, a valve cover, closure plate ect. Nearly any manual you follow will tell you this.
Cant wait to to see this beast mounted on something to see the outcome. Great work
You can tell he was busy while he was out, his video production quality got much better after the crash.
great vid with informative content. strong sounding engine. glad to see you've hit the ground running after your recovery. i enjoyed the joke as well.
May have to add a Wheelie bar.Awesome work!
ty for putting voiceover it makes everything way more understandable great video
Thank you very much for this Vasily! It reminds me of Oliver Motorized, whom is abroad and I miss. I appreciated the video style very much, and before I forget, thank you sooo much for 6:55, awesomely done. I wish you health and may you be able to keep this fine work up! Sincerely Alicia Antoniadis from Sweden.
Nice one dude
That thing almost sounds like a Harley motor.
Its a V-Twin what do you expect
Well, it's a pushrod V-twin just like a Harley so it makes sense.
@@LNERMallard harley sound is all about the connecting rods on one crank pin. In this case..... Hardly Davidson
It's a 90 degree V twin so much smoother running than a Hardley.
Cause it is
You’re pretty impressive with your knowledge of engine’s I was blown away watching this , nice thumbs up 👍
Perfect man I love the engine build can’t wait to see her rip
Hi..liked the video, nice job. I use the Predator and similar HP V2 engines on ultralight aircraft. The engines are installed stock but without the governor. In our case propeller load controls engine RPM, usually set at about 4000 RPM max. Engine reliability is especially important in aviation so I'm reluctant to boost the engines all that much. As HP is boosted, heat dissipation becomes a greater concern. I'd install head temp or oil temp gauge to monitor heat, especially if OEM air shrouds are not used. Oil cooling is a great way to control engine temps. The OEM oil cooler rad depends on shroud controlled air flow to provide proper operation. Without the fan and shroud I would consider a larger oil cooler if engine heat becomes an issue. I'm guessing an after market automotive tranny rad would be something to look into.
I enjoyed seeing that very much !! Thumbs up as always. When you were installing the crankcase side cover, i thought you said 60 ft-lbs. I was like AAAHHHH NOOOOO! 😱😱😱😱 but then i went back and re-listened closer and heard 16. 😁😁 Nice work and camera work too. I know that videoing & editing takes a lot of time. But this was a good thing to get on video.
Thank you!
I was kinda hoping that the supplier of that hot cam would sponsor you a pair of rods, i mean while you were in there and all. Have a good weekend, be safe !! 👍👍👨🔧
How can anyone not like this video it's really amazing when you did made it look so easy I am very impressed...😀
WELCOME BACK it’s great to have you back to make some great content. Glad you’re back in one piece
Dude... this channel needs a hell of a lot more subscribers.. you are great at what you do and so knowledgeable! I really enjoy your videos bro!!
Thank you 😊
You're very welcome bro you deserve it dude
@@VasilyBuilds hows the motor balanced the crankshaft and flywheel. U did good with the cam and carbs send me more info I'm looking at motors that are vee for small racing boats i like the availability of these .reliability at 5o hp ?and 8000 rpm is a must. Ss motors are not cheap.
That's a bad ass little engine, totally waisted in a lawnmower or pressure washer, I'd say you found the application it was made for, sick little ride
What does a waist have to do with anything?
@@Icutmetal really? It isn't obvious enough that it was just misspelled but you have to take the time to point it out anyways? What must your life be like that a misspelled word is reason enough to be a smart ass and belittle someone you don't even know
AIRBOAT!
Dealspeed Says the guy who can’t take a joke.
wow, this was a really informal video! I'm going to love seeing it rip!!!
Great video and an easy guide for anyone diggin into one of these motors
I'm impressed. Where did you learn how to do all this engineering? You have a great future.
I know I'm not the first to say this, but well done for producing not only a fantastic, extremely watchable video: but more so for the engine build itself. Which I must say, surprisingly, it is the exact motor I was, 5-minutes previously, toying with the idea of purchasing. Then, within 5-minutes I was watching this eye opener of a video build. Good job all round me-8.
Thank you!
So happy to see you back at it again man, this thing is gonna rip!
Dude that's sick.i didn't even think of trashing the stock carbs.i am now.i have alot of work a head of me.thanks
Good video. Keep that fly wheel cover on or you can over heat the heads and cylinders quick.
I've seen 212 predator stock flywheels explode violently at high rpm. I assume these flywheels aren't any better. You should definitely upgrade the flywheel before you hurt yourself if you though hitting a wall sucked imagine getting hit with a piece of flywheel. you have a legit bomb there with that flywheel.
Yes. I have found chinese cast iron to be very inferior. An engine like this needs a steel billet flywheel and a decent balance job before taking it over 5000 RPM. Forged rods and pistons over 6000 RPM
Just make a scatter shield out of steel and brace it to the frame, it's really easy to make a compact one for a 212 might take bit more work for a 670 but definetly doable
you can't find cast steel anywhere and would cost a fortune for one from a machine shop custom made and a billet aluminum is $350 and you need to also buy a $150 high torque starter putting you bout $500 extra in the hole for just the flywheel and starter.
And I got a Hemi Predator I run with the stock flywheel 9500 RPMs several times never had a problem. Of course that's what the internal balance
Glad to see you're back! Looking forward to your videos on my YT feed. :)
Glad you’re back good to see you up and at it again!!!!
Wow I usually perfer 2 stroke engine sounds, but this one was mint!
ringy-ding ding...that's raw power
@@randyhertzberg7549 twin 350 2 strokes..😎
Be a nice bike engine. Nice cafe racer.
That is one heck of a build brodi good job man
Thats impressive, the exhaust note is just perfect!
Nicely done video. I had no idea there were other parts available for those engines. Upon what do you base your estimate of horsepower?
I'd probably run a 10-40W, while adding a larger oil cooler since you removed the plastic shielding that pushed air up and across the heads cooling fins.
naa straight 30
@@seanmckay3392you trippin. 10w-30 synthetic w 1/4 15w-40 T6 diesel oil. Shit is great, especially for older stuff
The only problem with 50 weight oil is that it won't flow well when it's cold. Not when it hasn't been Star Ted in a while, when the weather is cold. 50 weight is racing oil, and pretty much everyone that used to use it has switched to light weight synthetic, and this includes nitro cars!
Just found a couple of your videos from what I can see you're a pretty cool dude love how you ended the video with God bless keep up the good work inspiring young people to do something with the hands and minds.
0:30 it sounds like you know from experience Lol, just kidding I’m glad you’re alright
U should put a supercharger on that thing, really liven it up. Plus they don't cost very much for something that small.
A big yes on a force fed project
Hey dude glad your back from that crash dude we prayed for you all that you'll be better
That sounds and looks pretty good, good job man. And God bless you.
Let me know if you’d be interested in me machining some weight off that flywheel for you. No charge.
It doesn't matter if you remove let weight if it's a cast flywheel because it probably have small and bubbles. And billit flywheels have way less bubbles and are more solid than cast ones . So if you machine away weight and make it thinner it will be more likely to explode that it would before you remove weight because it's more brittle.
Isn’t a heavier flywheel better for off road use?
@@isaaczahra6246 the stock flywheel is good for torque and slower revving up. Billet flywheels arw lighter and rev faster and are better for high rpm
Should've port and polished the heads while they were off.
Polishing doesnt always work..as some roughness is better for swirl...hence fuel/ air mix.
At around 4K rpm the valve is opening and closing 33 times a second. There’s plenty of turbulence to mix the gas. Polish =flow=GO!
Check out the David Vizard videos. He explains where the best gains are to be had when porting cylinder heads.
Man it's nice seeing you back at it!
Keep up the good work happy to see you back ✌
Imagine one of these but somehow it has been converted to a 2 stroke Dear lord the sound would be insane
Sounds like a damn B-mod at the race track looks good man I’m jealous I love working on small engines and that engine looks like a fun time
The connecting rod upgrade is a must if your going to do the other mods ! the stock rods were not made to with stand the extra power ! BOOM !
Yo young blood I love this video. Great content. Reminds me of me of my youth. When I rebuilt my Tecumseh 5hp.
This would be nasty on my kids go cart
0:38 good Lord I pray to the sole that has to attempt to operate a pressure washer that uses that big of an engine
there are pressure washers that use a 100kW turbodiesel and need an entire truck to move them...
Great video, sounds great too, thanks for sharing and looking forward to your next video
Such a clean built engine keep up the good work
cars and cameras proved you can do a lot with stock hardware, just dont expect this thing to turn 9kRPM without a fan explosion or throwing a rod, all in all, i will say this thing sounded sweet, cant wait to see it on the buggy and making some power, also glad to see you back at it man what doesn't kill us makes us stronger and adversity breeds success, keep at it my friend
Man this thang is killer!! I want to build a cart for the streets as where I live I can ride stuff around and bomb backroads!! Thanks for the inspiration
Nice work. Great footage and narration. Sounds great 😬👊
Dang, if you can get that on an actual Dyno and dial the AFR's in, i have no doubt you can push over 40hp at the crank.
yoooooo what a savage " the thicker the better, just like women" LMAOOOOO
Certainly sounds good. Thanks for sharing.
Glad to see you back and in great health stay safe and this is a great viedo
Thank you brother
I've never heard a small engine so bad ass before
Sounds like harley👍
Great to see you back! Greetings from italy!✌🇮🇹
Honestly sounds like a v8. Sounds really good bro. Good job👍
#thickerthebetter
Well then just put a 15 mil carb on one cylinder and 50 mil on the other best of both worlds hahahahaha lol😂😂
I wonder if you know this dirt racing trick? Put two higher compression pistons in the two back cylinders of a V-8 built for dirt track racing. It accomplishes something similar to your suggestion.
I want to build a board track tracer with one of those. You have inspired me. Thanks for the video.
So glad you are back Vasily!
