I had the same issue you guys had not having the .03 gage. So I googled thickness of a couple of house hold items. A grocery bag is .01 so you can fold it and get the measurement you need. It worked like a charm.
120 feet aint enough, you are JUST STARTING to get into that upper RPM range that the port and polish work will shine. Do another vid, but go out to 300 feet.
Im sure the wet surface did not help. im sure the modded head added power which reduced traction you were already having issues with. Stoked for the 60mph vid tho.
I shaved my hemi 212cc head 0.60 thousands and lightly ported I picked up lots of low end grunt from the comprrssion alone. Higher compression does get you out of the hole.
I have the predator 212cc on my mini bike. I have a problem we're after like 20 sec to 1min after running it will just shut off on me. Can any body help me address this problem
In the predator owner manual it says the intake valve clearance should be 0.004"-0.006" and the exhaust clearance should be 0.006"-0.008" it is on the first page of the owners manual
Could you guys set it up with a torque converter and a small sprocket? So it would be nice because you would have the gearing to take off with the converter and a high top seed too with the sprocket.
I think the same as a few others and wonder if a lapped time test would show better results as these give you points of both high and low range. And 2nd well done on breaking 60mph, I won't spoil the best top speed but wow and again WELL DONE
Might need to jet up again, you should rig up a simple stoichiometric gauge (an autometer gauge, an o2 sensor, and a battery) and tune that buggy up. Also tap the tank for an oil cooler / oil pump / oil filter. Sounds like you need a timing advance too. Anyway, from the sounds of the teaser you made your goal anyway....keep a rockin...
correct valve lash on those things is .006 intake and .008 exhaust, +/- 1 thou. ike was right to call bullshit on .003 both sides. if for some reason you've got metric feeler gauges that's .15 and .2, +/- .02mm on both.
If you want to get more top speed take out that cl2 cam and put in a black mamba 275 that will help alot. You can always go even bigger but once over 275 you have to start cleaning room inside.
Hey guys I just bought a predator 212 and I have it on my go cart and the throttle only works when I have the choke on all the way but by that time I'm already going 20mph how do u use the throttle all of the time and can u make a video showing how to setup the throttle and stuff with a centrifugal clutch
my go kart has been acting up. it will only go like 5mph when u push the throttle all the way down and its top speed used to be 27. the engine sounds terrible. its a 5hp tecumpsi. do you know what the problem is?
Could be a lot of things, but most likely is a dirty carb. Pull the carb, CAREFULLY disassemble it (take notes or pictures for each step), hose it down in carb cleaner, toss it back together and stab it back in. Make sure you clean out the fuel tank too ;-)
Check spark, clean air filter , check gas put fresh in , clean the carb i, check the value clearance, other than that I'd get a predator for 100 bucks and be on your way
Scary stuff, legend says there is a cascade fuel injection method to tackle the barrier of spinning speed in a single combustion’s duration for 16 strokes, 32 strokes and 64 strokes by injecting more fuel.
The head work shouldn't really make any difference in the low to mid revs. which is all you're getting to in your runs. It will however make a substantial difference in the upper revs.
Mississippi Mud Team the low oil shut off is known to cause this. unplug the yellow wire that comes out of the front side of the engine. if you do this always check your oil level before each ride.
If u bump compression it eats ur get up and go but helps you produce a better power at speed but if u decompress u can run higher rpms and better of the line but have a weaker power band
Hey guys, i cant find the info anywhere, im ordering a 212 predator and the performance kits stages 1 and 2. I need to know if the engine im ordering is a hemi or standard, any wisdom?
Probably because they don't have to pay for the predator 212s on account of their gopowersports sponsorship. Prolly the same reason they product place every five seconds, that they never name any other brand of parts anything other than generic 'what it is'. They're pushing GPS pretty hard, in return, they're getting a LOT of free shit.
Jeff Green. They can use a predator 212, run tav2 30,gokart motor mount provided by go power sport if They want to jackshaft it to work and still thank their sponsor.so i dont see a reason why not to build it.
Japan is built to better tolerances and better quality. I have a Tillotson TCT Mechanical fuel injection Unit $30.00 I'm going to compare it with a Mikuni 22mm carb kit I have all billit components & Flywheel In a BSP 196c.c. engine with Black Mamba cam w/#18lb. Valve springs
Drinking game!!! Take a drink every time u hear them say this!! Loll It's will be fine Testing purposes only Thank you go power sports Really like your guys channel!! Very helpful!!
Love the videos however I cringe when I see the tools you use sometimes. Adjusting valves with adjustable Crescent wrench and vice grip pliers in this video shows bad habits to the young folks trying to learn mechanics and proper tool usage. Bad example in my book but I really do enjoy the video. Good quality!
Taller tires! Also, I remember watching professional kart racing years ago, the drivers had to adjust the carburetor when they would hit the top speed straightaways.
The rollers in the torque converter are too heavy - notice the bog? Modified and stock both had the same problem. The ported head won't flow better until it's in the higher rpm ranges... Oops - no torque converter? Stronger clutch springs to delay engagement, then.
"Why do we keep working at night?"
"Because we had a big pizza earlier. Had to take a nap"
Best quote yet.
Kel DeWeese so is that what they call it now a days lol
If Engine Masters has taught me anything, it's that ported heads are literal magic.
Do you have MTOD?
Ryan Mcelderry Yes.
Sheehy/ hell ya they are so much more power i did on myself and it worked beautifully
I had the same issue you guys had not having the .03 gage. So I googled thickness of a couple of house hold items. A grocery bag is .01 so you can fold it and get the measurement you need. It worked like a charm.
heads don't make much difference until you're in the higher rpm range so the heads can take advantage more air flowing/moving through them
120 feet aint enough, you are JUST STARTING to get into that upper RPM range that the port and polish work will shine. Do another vid, but go out to 300 feet.
absolutely correct
thats the point
it would be obviously faster if they did it longer
CarsandCameras did you guys fix the crank case ventilation
should also replace the clutch with a race clutch, give it that umf it needs on launch
I've heard of a ton of different measurements for value lash but .003 is the one I heard the most
Stock predator valve adjustment is 0.0039-0.0059 per the owners manual that comes with them. That’s for both IN /EX
......with the 18lbs springs ?
With 26# springs???
Man you guys always make my Mondays better, you guys rock!!
with a shaved head on that engine does push rod length need to be corrected like you have to do on cars
What happened to the turbo drift trike
Used to use sand paper on heads bump up compression a bit still sure people do that way as long as its true flat
Specs on valves is intake .10-.15mm, exhaust .15-.20mm. (0.004"-0.006", 0.006"-0.008")
You guys didn't lap the valves ?
Yeah right lol
I want to see if the mikuni makes a difference on acceleration and top speed
It does
use different fuel when you up compression aka cam and shaved head it will ping if not using High enough octane fuel
They use 93 thats well enough
Im sure the wet surface did not help. im sure the modded head added power which reduced traction you were already having issues with. Stoked for the 60mph vid tho.
2:13 mark, noticed the arrow on the piston pointing down...isn't it supposed to point up?
No it points at the push rods
@@dizzywright4379Fuuuuuuudge. I gotta go fix something. : (
excited for tomorrow! i saw no smoke on the teaser run and im pretty sure i heard 65!
Doesn't it make more sense to adjust the valves when the motor is warm?
When will you work on the 66 c10 in the garage again!!??
I shaved my hemi 212cc head 0.60 thousands and lightly ported I picked up lots of low end grunt from the comprrssion alone. Higher compression does get you out of the hole.
Why don't you put a torque converter on that go-kart?
Flow before compression. Makes more power every time.
I have the predator 212cc on my mini bike. I have a problem we're after like 20 sec to 1min after running it will just shut off on me. Can any body help me address this problem
Or put some oil in it.
In the predator owner manual it says the intake valve clearance should be 0.004"-0.006" and the exhaust clearance should be 0.006"-0.008" it is on the first page of the owners manual
racing clutch time
Could you guys set it up with a torque converter and a small sprocket? So it would be nice because you would have the gearing to take off with the converter and a high top seed too with the sprocket.
Tap and diy set that's what the tools called. Y'all r awesome going to go buy a set asap
why test on such a short distance? sounded like it was just barely starting to make power at the 120 foot mark.
"Gatta get these studs in." Ike: "Im right here!"
I heard 62!! I hope I get this go kart frame today I'll be coming for you guys
Our Lady of Blessed Acceleration, don't fail me now.
After the new head you can tell that it bogs a lot at the start. Add more fuel at low rpm and it will be much faster.
How did u not get water in carb. It was pouring.
You have the right tool for valve adjustment, just add smaller shims together to get your size.
Valve lash on most small engines is between 4 and 6 thousandths (.004-.006). Any tighter and u rish burning a valve
Risk
FINNALY SOMEONE DID IT!!!!!!!!!!!!!!!!!!!!!!!
I think the same as a few others and wonder if a lapped time test would show better results as these give you points of both high and low range. And 2nd well done on breaking 60mph, I won't spoil the best top speed but wow and again WELL DONE
The upgraded head sounds nice, at least! Great video guys :)

Also tap the tank for an oil cooler / oil pump / oil filter. Sounds like you need a timing advance too. Anyway, from the sounds of the teaser you made your goal anyway....keep a rockin...
Yeah ike make a demo derby car like so they can see
wthomasw2. Agreed
correct valve lash on those things is .006 intake and .008 exhaust, +/- 1 thou. ike was right to call bullshit on .003 both sides. if for some reason you've got metric feeler gauges that's .15 and .2, +/- .02mm on both.
Where is the video of Ike doing the porting and polishing of the head
That performance head can perform in llong distance not for short distance.. less torque but in long distance it will perform well
If you want to get more top speed take out that cl2 cam and put in a black mamba 275 that will help alot. You can always go even bigger but once over 275 you have to start cleaning room inside.
Allen10390 pretty sure they have the mod2 cam in it
Anything over 265 lift cam you need dual springs. This is coming from dyno cams engine builder.
Hey guys I just bought a predator 212 and I have it on my go cart and the throttle only works when I have the choke on all the way but by that time I'm already going 20mph how do u use the throttle all of the time and can u make a video showing how to setup the throttle and stuff with a centrifugal clutch
Bama Bassing that sounds like there is a problem with the motor
Matt Schork it's a brand new engine
I suspect a vacuum leak.
if you over jet a carb will shaving the head help
Debbie I wonder because I accidentally overbored my jet
No
Did you reseat the valves? Because you should have shown it if you did.
That driveway drag is mostly clutch slip. It sounds stronger though.
.003 was what it said on the sheet on the stage 2 dyno cam
Same with my Hot 265 cam 0.003" for both.
where did the head come from?
my go kart has been acting up. it will only go like 5mph when u push the throttle all the way down and its top speed used to be 27. the engine sounds terrible. its a 5hp tecumpsi. do you know what the problem is?
bloodyAiDkIt sounds broken.
Could be a lot of things, but most likely is a dirty carb. Pull the carb, CAREFULLY disassemble it (take notes or pictures for each step), hose it down in carb cleaner, toss it back together and stab it back in. Make sure you clean out the fuel tank too ;-)
The problem is its a tecumseh
Check spark, clean air filter , check gas put fresh in , clean the carb i, check the value clearance, other than that I'd get a predator for 100 bucks and be on your way
Sounds like you should clean your carb
Hello, if I wanted to tell you a track bike like that, you will settle them with them, except for Jordan. How much does a dollar cost?
I have a basically stock 212 predator on on a mini bike that will do 40 and will wheelie with the smallest amount of throttle applied
Brodie Lueken that just means you have a lot of weight over or behind the front axle
Brodie Lueken rear axle*
Surely you did lap the valves after switching them?
when the engine is cold, .001. when it warms up, the clearance will open up to approx .003- or .004.
I think he said "67" at the end. @11:35
62
Really hard to tell what he said! Sounds like two syllables at the end. We'll find out soon. The suspense.
Maybe 57. I doubt they're at 67 yet.
mike stradling definitely 62
Just listened again and I think he said 66! LOL. I dunno.
Scary stuff, legend says there is a cascade fuel injection method to tackle the barrier of spinning speed in a single combustion’s duration for 16 strokes, 32 strokes and 64 strokes by injecting more fuel.

Hear hear
I need help I have a predator 212 in a go cart and every time I turn or drift it dies what do I do
Mississippi Mud Team the low oil shut off is known to cause this. unplug the yellow wire that comes out of the front side of the engine. if you do this always check your oil level before each ride.
Matt Hudson will do thanks for the help
Did I see you swap out valves and not lap them?
What chassis is that it's exactly like mine
I love yalls videos
We*
If the clutch is slipping then take the bell off and clean it with sandpaper same with both the bell and actual clutch pieces
I cant find the hemi head here in california
If u bump compression it eats ur get up and go but helps you produce a better power at speed but if u decompress u can run higher rpms and better of the line but have a weaker power band
Should I take the governor off my yerf dog because it takes time to go fast
reptiking YOLO
Hey guys, i cant find the info anywhere, im ordering a 212 predator and the performance kits stages 1 and 2. I need to know if the engine im ordering is a hemi or standard, any wisdom?
How much would u charge me to build ma a super kart carsancameras
I go kart shakes a lot what shout I do for it can stop
So if you guys wont do a motorbike motor can you at least address why?
Probably because they don't have to pay for the predator 212s on account of their gopowersports sponsorship. Prolly the same reason they product place every five seconds, that they never name any other brand of parts anything other than generic 'what it is'.
They're pushing GPS pretty hard, in return, they're getting a LOT of free shit.
TestECull Yea i figured as much but it almost seems like they dont want to do it because theyre afraid to lose the sponsorship
Jeff Green. They can use a predator 212, run tav2 30,gokart motor mount provided by go power sport if They want to jackshaft it to work and still thank their sponsor.so i dont see a reason why not to build it.
Changing valves without reseating them? Should be losing compression, Big power loss
Do you recommend the China mikuni carb or pay for the Japan carb
Japan is built to better tolerances and better quality.
I have a Tillotson TCT Mechanical fuel injection
Unit $30.00
I'm going to compare it with a Mikuni 22mm carb kit
I have all billit components & Flywheel
In a BSP 196c.c. engine with Black Mamba cam w/#18lb. Valve springs
sounds like you have a flat spot on take off maybe up the needle a notch
It does sound like it bogs down right after it gets rolling.
David Simpson that's when the centrifugal clutch is fully engaged.
Can't up the needle in a stock carb this whole video they didn't use the mikuni...why not...it's beyond me I would have had that on from the start
U guys should put a profiler on the in takes
Did you guys put a cam in it? If so what size? Stock valve size or oversized?
There is no substitute for good head...
Drinking game!!! Take a drink every time u hear them say this!! Loll
It's will be fine
Testing purposes only
Thank you go power sports
Really like your guys channel!! Very helpful!!
Why don't you put a torque converter on it
Instant 20% loss in power due to friction.
Defeats the purpose of the test.
Get a higher stall clutch it will skip past some of the low end where it don't have as much power...with the bigger cam you sacrifice some bottom end
man it rains there a lot ! great work men !!
Love the videos however I cringe when I see the tools you use sometimes. Adjusting valves with adjustable Crescent wrench and vice grip pliers in this video shows bad habits to the young folks trying to learn mechanics and proper tool usage.

Y'all live in Seattle?? Always raining in ur vids
They live in North Carolina
Taller tires! Also, I remember watching professional kart racing years ago, the drivers had to adjust the carburetor when they would hit the top speed straightaways.
VA Outdoors Sportsman On certain carbs that's true. I had a tillotson on methanol with an adjuster attached to the steering wheel.
How do you adjust the brakes on a go kart?
Lane and Carson depends on what kind of brake setup you have
I would actually like a video on this too, i've been trying to get my kart working for a long time, but I keep struggling with the brakes!!
Brakes only slow you down.
Yup.
Flattrack motorcycles don't have brakes.
The pros can have em but not the novices.
You just punch the gas to slow down.
Also .003 intake and .004 exhaust or .004 and .005 what ive been told multiple times
I never noticed the BMX seat post clamp on the silencer 😂 let me dig out my BMX stuff lol
Ya usually fhe lash on exhaust valve is always more than intake
where do you get the hemi version of the predator 212 engine? Does go power sports have them?
nashguy207 harbor freight
The rollers in the torque converter are too heavy - notice the bog? Modified and stock both had the same problem. The ported head won't flow better until it's in the higher rpm ranges... Oops - no torque converter? Stronger clutch springs to delay engagement, then.
Less weights in the clutch? It's gripping too early and making it bog
Hey where did you get your seat from
What about lapping the valves
Do you guys paint your exhaust ? If so what paint should I use
Port and polish helps alot more on the big end...
comeon guys. its 08:30 in germany. ITS TOMORROW ALREADY!!
So your replacing the enginee head with Mike's head?
What kind of fuel are you guys running?
you guys should really invest in some lights, either for the front yard, or the go karts themselves. You can get high powered 12 volt ones!
can you build a 1000cc go kart?
