the detail installation and walkthrough is awesome. it really helps out alot. great stuff
Great job guys you nail it for the newbies that was a perfect video keep them coming 👍👍👍 Thank You.
ua-cam.com/video/TYp7SgO_FrU/v-deo.html
Thank you guys. This was exactly the video I was looking for. Huge help. 😁
I order my predator 212 about 3 years ago with a stage 1 already installed from you guys and I love it it's still running very strong. It's already going to it's 3rd vehicle.
Nicely done!!
Did it have upgraded flywheel or other internals?
@@diepunk I order mine with original flywheel. I believe that would be the stage 2 or stage 3 not sure. I only do the stage one on my predators.
@@jorgegonzales878your flywheel has been fine ? I want to get more speed but worried about messing up the motor from too much rpms
well if ur scared to upgrade one thing to get more rpms but think ur engine cant handle it, you gotta add and upgrade ur engine so it can stand those high rpms :)@@Konnersaki
Heck yeah!! 2.5 stage kit is all my bike needs she SCREAMS🤯 i can't imagine the stage 4# 20+ HP keep grinding!!(=✌💚
Nice comparison between the 2! Great video!
Wow!.....What a gain in HP. Definitely worth it! Thanks Guys!
You bet!
Dude!!! This video was awesome. I think Go Power Sports has mastered every aspect of the predator engines. As a person new to predator engines, I really appreciate the level of detail that is in your videos.
ua-cam.com/video/TYp7SgO_FrU/v-deo.html
Thanks for the step by step. I'll be looking to modify my non hemi soon this video is a big help
I bought a kit after I seen this video and I lost a ton of power. More like I lost 2 hp. I’m removing the parts and issuing a refund.
@@georgephiliastides2949 u prolly fucked something up installing it
Nice! Im digging the new decals man. Will be ordering some soon!!!!
Newbe here. Love the info provided. I did flinch a little when ya cut the oil sensor wire so short. But, what I enjoyed the most was the music....".I looked down the road," from Moarn. Keep up the great work.
Man I’m excited to do it to my predator 212. I hit 35 mph on a 60 tooth sprocket bone stock and imma do this upgrade… of course leaving the 60 tooth sprocket. May go 40-45 then and looks awesome.
I just added tourqe converter and 40 tooth sprocket 12" tires have 23mm carb jetted K&N air filter I have not mph with car yet but it's so much faster that it's squarely top end enough I let out of it I assume I'm hitting 45 or 49 mph just guessing from the feel
Heck ya that little dyno is awesome big like and share from tbc
these videos are good as hell! appreciate all yall in the small engine community!
Appreciate it!! Thanks for checking us out
Nice I will use this video for my first install
Biggest thing I got outta here was using the Allen wrench to hold the valve spring great bit of information
Nice video!
This video makes me want to strap a Predator to my easy chair and go racing!
Just subscribed!
Ha, let's see it
I can see it in my mind so clearly.
this must be why my order hasnt been shipped yet, theyre to busy making videos and dynoing engines.
When did you order? Been gonna order some stuff but have been worried about the shipping time do to the message saying they're behind and hearing it's not to timely.
My order took about 2 weeks to get to Cali
Ha, we're backed up because everyone and their mother is spending their Stimis on Go-Fast parts. We are working diligently to get everyone's order out...but more orders keep coming in!
That’s good at least they’re spending there money wisely other then other stuff that won’t last them. I didn’t get a stimi sadly but my cash is still the same you guys shouldn’t blame it on that instead y’all should be happy you guys have income coming in and still in business
Pay your employees and get it done.
When you install a stage one kit do you not remove the governor?
Excellent video definitely recommend 👍
Glad you enjoyed it
Very cool testing the gains with the dyno. A little surprised how soon the power started dropping. I have seen other dyno testing where peak HP was at a much higher RPM than here. Their numbers may look a little different if the engine was heat cycled a few times then dyno at a normal operating temp. In other words, dyno when the engine is completely warmed up.
If you are running governed you don't need 18lb valve springs. At this RPM the stock springs may have gotten a touch higher power numbers because it takes more power to move an 18lb spring than it does to move a 10lb spring.
Maybe it's because they were running a none hemi on the other test?
it's because of the governor, that pulled the throttle back for sure.
wow i like the sounds
Great comparison. Like to see it with mikuni now.
Won’t that make it blow it up
@@tazcgnso8653 NO !
Or a new Asian Honda kehein carb of about 20-22mm & above, readily available & jetted spot on & mate up to a nipple bike throttle cable end ! You don't have to appear a guru to know what works for less informed
Thanks helped a lot!!!
Glad it helped!
I love this kind of video
me too...and the sound of engine is so nice
@@gilaspinoytv You haven't heard my exhaust systems
Cheers Trev New Zealand
I'm no professional but I have tinkered on stuff and putting that head cover on with a Impact and not hand starting those screws was pretty ballsy But other than that video was great I love the commentary is a really well put together walkthrough especially with the benchmarks
You should always torque the fastener by hand too. A impact gun will either be over tightening them or not tightening them enough.
I'm getting ready
Excellent and concise step by step instructions! Especially love the background music! Who is the artist??
Sorry, don't remember. We use Artlist.io and they have a ton of great artists.
U guys have a cool ass job 👍
I see you have your tachometer wrapped around the cord on your spark plug. I just got mine in the mail yesterday and the instructions mention to wrap it around that nubbin on the top of the plug.
Do you have a video of a non hemi on the dyno before and after a stage 1 kit? I'd like to see the power difference between them.
Or maybe a stage 2 engine next?
Great video. Would love to see dyno before after for stock 420 vs stage 1. Do you guys sell build engines?
Do the same with honda gx 390 please... Congratulations for the channel
Can you do this level of detail all the way through stage four please.
Step by step with dyno data backing the upgrades. I enjoyed your video.
Maybe with different cam and valve spring combos as well!!!!
Yea can i im triying to set up my own dump for frends but need some help
Just added 18lb valve springs to my 212, made a world of a difference.
What difference did it make?
Added about 600 to 800 rpm to my 212 with governor and gained me about 5 mph
I needdddd my clutch yallll I ordered it
I see ya got your GoPowerSports stickers on there. Don't forget your Cars and Cameras "It'll be fine" sticker (THAT'LL inspire CONFIDENCE in your customers 🤣)
My stage one kit didn’t come with a new jet or I misplaced it, any chance you could tell me the size jet to order or add a link?
Man I love your videos, you could not do any better explaining the process! The problem I had was I called your order department the guy who answered the phone was barley understandable, he did not sound like he knew what he was talking about. I have several parts I want to buy from you, just give me a name of who I should ask for that knows what they are talking about, other wise I will try to get my parts elsewhere.
Try my main man Evan. Or email us at sales@gopowersports.com. Thanks for the feedback.
Great video real easy to follow..my question is so you really don't have to change or drill out the pilot jet..andI have the Hemi are the jets the same for both because I keep coming across parts title non- hemi? See I did not know bout the jets I changed to this akir filter and adapter and now the engine wants to die with a little throttle so I came to uou gents!! Thanks keep up the great work
I appreciate it guys... I was really hoping you would talk about the replacement jet... now I'm looking for the size jet you went with everywhere and in comments. I apologize for being such a newb. What jet size did you replace with please??? Thanks again!
I'm installing one of those on my beach cruiser bike...
You'll be kicking sand everywhere!
For the starter moving it. Do you have to do anything with the rope or is it as easy as taking it off repositioning it and bolting it back on?
Just did this. It's as easy as unbolt, turn and rebolt.
Do you have to install the new valve springs for this to work? That seems like it’s above my talents
Hey Taylor good morning, thanks for the helpful video how tos. I have a Honda gx160 and I’d like to keep it stock but I’d like to know if you guys carry the throttle cable swivel nut not sure what is called. Thanks in advance and ride safe.
Thanks for the content ...I am having quite the time trying to figure out what size bolts fit the four bracket holes on the case cover around the crankshaft??? I thought I figured it out and bought some but I don't know if they are different because it's a hemi or what... I'm swapping engines in a trailmaster mini bike and the cvt brackets for the cvt cover/guard need to mount into these holes on the predator but are a different size on the two engines... I want, based on my limited experience, to say they are either 8 or 10 metric...do you know what size they are???
I'm curious if any of this stuff would work on the predator vertical shaft engine.
How do you know/tell the piston is top dead center when rotating the shaft to change out the valve springs? Just look inside it or is there some other trick?
Hello just wondering do the stock hemi an non hemi make the same power which one makes more power with stage 1 thank you
Good qstn cheers Trev NZ
Does this stage 1 kit require any billet parts or is it safe at moderate rpms?
I have bought it all and all nee clutch assembly. Its pretty fast. Is my belt supposed to almost ride the very top of the pulley? I backed out the screw to allow to give it the most gas. Should I change that screw back so the belt wont go to the top of tge pulley? Its eating belts in 30 mins. Has red spring in it and I have bought a green spring but not installed yet. I also have a 50.00 belt but dont want to ruin it. Thanks for any help! Great video and I used it to build my new 212cc.
So i have all these parts but the 18lb pound valve strings. Do i need them or will it run fine with the stock ones with a stage 1 on
Does the valve cover vent only let out crank case pressure or does it also vacuum air in?
Just bought a doodlebug yesterday with this excat motor and kit. I am wondering the best gas to run with this set up? Octane wise. My local ace hardware store has trufuel ethanol free tf3 4 stroke gas would that be safe to run with this set up. Gonna be ordering the billet flywheel, rod and gasket kit from yall soon since my governor bypassed. But so far loads of fun with the stage one kit.
So does this kit after installed remove or bypass the governor
Did you just change the jet or did you ad a different E-tube as well ?
Can you guys make a troubleshooting video for y’all’s Colman stage 1 kit that comes with the clone carburetor w/ jet already installed? I can’t get mine to run it will idol but as soon as I hit the throttle it cuts off. Everyone says to adjust the float but the float on y’all’s clone carb isn’t adjustable
Can you do a 212 non hemi dyno run for me with the stage one ?
Really not much difference. I own both engines.
@@tbonevoodoo I have a Coleman ct200u and the stock engine blew up. I had a stage 1 kit on that engine. that I would like to put on a new predator. Will a stage 1 kit work with the hemi or just the non hemi or both?
@@Troygehring Both
@@tbonevoodoo thanks
Sound would be good
question ? so i got a new harbor freight 212cc motor have never got it to start ever i took govener off unplugged and removed oil sensor even changed out fuel line tubing put gas and oil nothing happens i did notice that theres no gas getting to my carb at all even when gas lever is on and throttle is opened up theres no gas flow from tank to crab ? this is motor has never been used its been almost a year and not once has it started ive tried everything no luck wut shouls i do
Can you use the same kit on a duromax or more specifically on a 420cc or a 440cc duromax or should i just stick with the predator? And should I go with predator 420cc?
I put everything but the 18# springs on a non hemi motor. Will that cause it not to run right.
Another question...so got this kit and the header pipe is NOT flared on the end. How do I attach the muffler? Welding is not an option.
Is a valve cover vent filter necessary? I swapped my baja warriors carburetor and muffler and air intake first I did the muffler and tourque converter I had original carburetor and air intake and it was going like 27 mph and thats 3 mph faster then it was going and then I installed the new carburetor and air intake but now it won't even get hardly up to 20 mph so I figured maybe the new carburetor had a small holed jet so I shaped that out for my old jet cause I was right and that still didn't make a difference idk what else to do
I wouldn't say necessary, but definitely recommended to ensure you don't get debris in your valve cover.
What if the power gain was because of simply from removing the parasitic drag caused by the governor and none of the other parts were needed. I’d like to see a dyno run of a stock 212cc with and without the governor
Same
Governor limits the revs to 5,500 without it the engine can go to 8,500 that’s the difference. U get a higher rpm range so obviously more power
@@Slowboi335xi more rpm doesn’t mean more power. Especially if your cam doesn’t make power in the upper rpm range. The stock cam falls flat after 5k rpm
@@Slowboi335xi also, the coil also limits the rpm. U can buy coils with no rpm limit
@@FreddyFunderbunz not true at all regular 212s don’t have that
do any of your guys billet flywheels come with magnets inside so i can still run my headlights?
I did this except the valve springs and no muffler. Removed governor. It's on a traditional go kart frame and im getting 42mph ish and I weight 260lbs. Its a torque converter running to a 48 tooth sprocket and has no problem spinning the wheels in dirt. It really takes off. I dont know what the difference is but I have had better luck with the more expensive tq converter from this outfit than the cheaper ones on ebay not to mention the hardware was better thought out. I think im going to do these other mods and ditch the 420 on my explorer it's just been a pain I think 10hp not to mention no governor will be sufficient. Just easier imo. Easier to start, easier to get to etc. Plus I really want to get rid of the 40 series and all the jackshaft stuff.
same here but 40 tooth carb jetted air filter & header ima around 45 to 49 mph
same here but 40 tooth carb jetted air filter & header ima around 45 to 49 mph
I just recently installed 18lb springs in my non hemi predator 212 and my minibike is actually 4mph slower now. Any ideas or insight on what may have caused this? Thanks
Double check clearances and springs wont really make it faster. Just makes it safer to run it faster
How do you know if you have a hemi engine? Does it state it on the engine anywhere? Thanks
I wonder what happens if you only change the speed setting screw, without installing the upgrades?
I reved mine 6200 a few times honest to God it's bone stock
Now do the Tillotson you claim 10 HP stock.
The Tillotson should get better dyno numbers than this. Higher compression, better head and carb will do it. And don't they come with a better than stock cam? With identical compression, same carb and cam a Hemi 212 should produce close to the same power of the Tillotson.
I have the hemi predator 212cc with a hot cam, 26lb springs, billet rod, billet flywheel, billet side cover, and a mikuni 22mm carb pushing a juggernaut torque converter.
Anyone know if I do all these changes except the valve springs will that affect the effectiveness of the kit or my motor?
Dominic for someone with a vested interest you'd think your qstn would be answered - yes not swapping out the stock v/springs will effect the engine & how high you can rev it before potentially damaging valve float.T goodluck
Nice. Curious how an 8 degree ignition advance would affect those graphs
that is the first thing i install. they start so much easier...
Wouldn't recommend that on the hemi 212
I had a honda gx 160 20 years ago we put the 308 cam in it stock rod stock flywheel had head work done bid carb and torqued the stock rod twice the stock speck stock flattop piston gapless rings and they aint make a billet flywheel yet and i used to turn that thing 8000 rpm with stock rod never threw a rod and that thing would run with the heavy flywheel its a wonder it didnt explode we did drill bunch of holes and lighten it it ran like bat outta hell till flywheel blew up we also avanced the timing from 16 to 40 degrees and it would only run bout eight milr then it get hot but the timing made that thing a rocket we also cut 100 thousands off the head with all that timing it was make pass and shut it off couldnt ride it but man that timing picked up alot of power but you cant turn it up that high and ride it it would over heat but just drag race it was a beast and i cant believe the rod stayed together at 8 grand that old honda stuff was strong

Too bad you guys have none of them... but let's learn for free!. And that's cool 😎👌
Very true!
Have you all got your hands on the Predator "go cart" engine? Interested to see if it performs well with the off road frame
How about with the governors removed on both...
Can you dyno a stick predator ghost? Can the ghost use the fuel tank and gravity feed to the carb or does it need a fuel pump?
So i put a stage one kit on my predator with the springs, jet, air cleaner, and header but now its shooting oil out the valve cover what could be causing this?
How did you run it after the install without an oil catch can an not make a mess or venting the ohv back back into the motor?
It's more preference to run a catch can. It's just a small amount of oil that you won't see an oil loss. Put the filter above the valve cover helps a lot.
There's a crazy viking building a 50cc 2 stroke in his garage that's dinoing 20+- HP and 14 lbs of torque .
Great job guys !!,How much would you charge for that complete mod on a new predator motor and where can I buy one
check out our engine site on www.gopowersports.com
@@GoPowerSports those are nuts! I wasn't sure I wanted a mini bike till I saw what those things can do!
Has anyone has any issues with the idle low rpm jet after this mod? My engine wants to die when I blip the throttle quick. Also noticed I need to choke the engine even after it's warm to get it to start. Pilot low rpm just seems lean condition now.
Hello! Quick question, is my silicone exhaust wrap supposed to smoke? If so, for how long?
Yes it will. Usually after the 1st two rides it'll stop smoking. It's just the material adhering to your header pipe.
Why does the jet sent with the stage 1 kit make my predator and 2 of my friends predators Bog out .. bone stock . Installed air filter . Exhaust and jet . Same result on the 3 predators . Will fire up but as soon as you give it throttle it bogs out .. what’ causes this . Same result on 3 different engines with your stage 1 kit . Runs fine with the stock jet . As soon as you swap it out . The bike will bog out
my kart with the bigger jet likes to foul plugs/ run rich
@@landonbutler385 & there's your answer !.Get an oxygen sensor bung welded to your exhaust pipe & fit a wide band poxygen sensor & get hooked up to a smog tester & run it off an independent battery to heat it, your local EPA sniffer shop or local garage with an air-fuel sniffer if you pester them enough should be happy to oblige.Dont forget the local small engines man.Goodluck.Cheers Trev NZ
You still have to tune the carburetor. Any time you change altitude you will have issues either lean or rich. Plenty of videos on how to tune these motors out there. Takes about an hour or so. When you get higher up on the performance scale even temp changes will affect your tune. Now you're getting into the spark plug temp rating and other factors that probably will boggle your mind.
Harbor Freight has 212cc motors on sale atm. Bought me 2 of them. $130
Nicely done!
do a dyno on each predator like 79, 212, 301, 420, and 670
What jet size would I have to put in? I’ve been watching so much videos and no one explains the size jet the use
I got a go kart with all this but the valve springs. I'm afraid to open her up the front wheels leaning in almost hitting the control arms I guess they're called... I ordered spacers to fix the issue hopefully.
Are we assuming that you took the governer out ?
Do you offer any seat post tube engine mounts?
Thank for the informitive vidieos.
Yes governor is out and no to seat post engine mounts, we just have the flat engine mounts that may be welded.
I put the stage 1 kit on without the jet and it’s cutting out would it not cut out if I put the jet on?
what would an engine like this work on a snowblower? tried searching.. didnt find any videoes on it
Is there a way to hook up a hand starter to replace the pull starter.
Question - I have an X-Pro 196cc Mini Bike. Can I order any one of these Upgrade Kits for the Coleman 196cc Mini Bike for mine ? In other words will the Coleman Upgrade Kits work basically on any 196cc Mini Bike no matter the brand of Bike ? Mines a Chinese Bike.
Hi I would like to know what is the max rpm for gx200 with stock flywheel
Seems like we end up needing another thick carburetor gasket for space so the choke lever doesn’t press against the choke bracket screw and has space to turn back and forth
What fastest you got theses 212 to go?? And what’s the biggest stage for the engine
So if I put 18 pound springs on my predator 0 or 1000 lash would be good?
Why did y’all stop selling them in kits, it’s all separately now
whenever i click the link in bio, it just takes me to a listing with just an air filter, wheres the exhaust and stuff?
please help me out guys you can install these valve springs with stock carb (changing jet obviously) but you don’t need to remove the governor?
I guess you could add the 18# valve springs with your governor still in. You would see the most benefit after you hit 5000+ rpms though from changing out these valve springs.
