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.
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
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.
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.
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.
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
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?
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!!!!
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.
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
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.
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
@@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?
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
@@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
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
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.
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!
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
The heavy valve springs only help at rpm. over 4000, high revving to stop valve floating. With the governor @ 3600 they make your power worse, taking away energy to push open the stiff valve springs.
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 🤣)
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
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.
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
@@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.
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.
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.
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.
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???
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.
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.
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.
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.
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
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
I ordered a stage 1 kit forever ago. Installed it and my Kart never ran right again. Just now realized it didn't come with the jet kit :/ Any idea the size I need to find?? 1 × Stage 1 Predator Performance Kit for 196cc & 212cc engines Filter Color :BlueAdd The Exhaust Gasket:Add the Exhaust Gasket [ KD212EXG]Add Vent Filter Kit [$9.95]:Add 2 Vent Filters, 2 Zip Ties & Tubing Unfortunately this product is no longer for sale so it cannot be reordered.
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
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.
