Predator 212 5000 RPM Governor Mod (Not Removal) 

if you exceed the factory set governed rpm without removing the governor wheel then the governor wheel can shatter, causing terrible engine damage. It's just a risk you have to take. Just wanted to throw that out there.

I just bought a brand new hemi 212 predator and the springs are already in these exact locations,

You won't hit 5000 rpm only with this "mod." On your other video, you have an upgraded exhaust, air filter, and possibly other "NR Racing" mods and you still didn't hit 5000 when you hooked it up to a tachometer. How can you claim 5000 on a bone stock motor just by moving a spring?

anything worth doing is worth doing right,,, Just remove the governor, its not hard,,,

dam shame you have to leave the engines stock in your races.....

Just checked my motor to do this as well and the springs are already set that way from the factory , I will adjust that throttle set screw tho

FWIW the little round nipple on the choke lever is for plugging the fuel line. Fits perfect. Good video, thanks.

Uhhh so this is for go carts?! 😂 I stuck mine on a minibike

wish i could of seen this before i took mine off

Huh! I just learned something new. You're right, there is tons on governor removal, but this is the only video or article that goes into adjusting the governor without removing it. Thanks :)

Do you get your parts from Gopowersports?

So I want to do this mod but I worried I could blow my block, how long have you ran it like this with no problems? I have added a header to my engine and thinking about geting the jets and filter from go power sports to add to it, what are your thoughts?

Hey back in the day of flat head B&S engines, that's all we had to do is move the springs, or bend the fan blade that was acted upon by the flywheel fam that cooled the engines! I got 30 mph out of my little Fox mini bike with a 3.4 B&S engine! Wow I only wish I had one if these engines! Back then the best engine to start with was a 6 hp B&S engine! That was available new for around $150! But that was a lot of money in 1968! But my buddy and I installed one in his Sears mini bike that came with a 4 hp Techumsa and a small tq converter with a jack shaft the world leave a small 4' patch of rubber on concrete! But we added that 6 hp Briggs with a tweaked governor and got just about 50 mph! Plus s 10' patch on concrete! That little bike could run with Yamaha Mini Enduros till the Yamaha hit top gear! Plus it could climb hills like mad! We then had to put bigger tires and wheels on, with a front fork that came off a Yamaha! I wish I had a photo of that little beast! It was king of the minus back in the day! I ended up buying a new Hodaka Ace 100, just so I could run with him! But them he ended up buying a 125 Penton ISDT and we both grew up!

I done this on 196 coleman mini bike, did not work move the large spring around nothing!

I would say static adjustment for the governor arm should have been mentioned. Most people know about the throttle stop screw that needs to be removed, but i had to losen the static adjustment very slightly to get a full close, and full open with this given adjustment that probably increaced my rpm from 4000 to 5000.

does not work

all I did was remove the governor arm. ran a rod from the carburetor to the throttle.. new fuel tube.. new pipe and absolutely no air filter pure air flow 40 + running strong now for months

Good video, i will do this after i just get it running thanks, im trying to get an old school mini bike going, i went with Northern Tool brand 208cc motor called the ironnton, have not found any videos or info on these motors. Main reason i went with it was the rearward pull of the pull string , apposed to predator forward pull. Problem i'm having is these newer motors are much wider than the old motors, clutch and rear sprocket dont quite line up, i have more room on shaft to move inward, do youall know of any parts suppliers with deeper offset clutch sprocket, and a rear wheel with longer axle shaft, or is it ok to use 3 - 3.5 inch spacer. thanks for any help, i'll be 60 this summer and have been out of the mini bike world for about 47 yrs! Its so dang cool to see and learn so much from you tube, WE ARE REALLY LIVING IN A GREAT TIME.

I did adjust motor as much as posable, even went with stainless steel smaller diameter bolts, i'm about 1/4" off or less, have you heard anything good or bad about ironton motor, and as far as 3.5 inch wheel spacer, is that ok to run. thanks again

Yes do you recommend doing it. Do you gain rpm.

Just rebuilt my minibike (did a little mini video series) i'll have to see if my 6.5hp Powerfist motor has this

all predators come like this, it's not a mod

Thanks for the help on the plug.. Would you know how I can get the emolshone tube out. I removed the jet but the tube appears stuck up in the carb. Thanks for the help...

How did you add a second wire to your tachometer in your other video? I think I have the same one from amazon and it only has one wire and that wire is stranded not holding two inside the sheathing. Thanks

can you make a video on how to tune a carb... im new to go karts im a dirtbike rider

Could you put up a video of what spring you need to use on it if it only reaches 2800 rpm still?

i have the same motor it comes on but when ever i give it gas it will not move and it cutts off

That's odd. My springs are setup exactly like this on a clone that came with the Coleman mini bike I just bought. I haven't ran the engine yet. The bike got all scratched up in shipping and I have everything apart to be painted when winter is over. For the "stock" racing class you speak of, are you allowed to remove the muffler and open up (grind out) the material at the flange to create a better transition of flow? Those mufflers are already very restrictive. Point is to do what you can to improve the stock setup with little or no money. It may help only a fraction, but doesn't every little bit help?

You just saved me $200, and my electric start. Thank you so much for this video. I am still a little concerned about the stock flywheel with 5000 rpm, but if you say it works, then it works.

I went and looked at mine. It was hooked up the same way I guess I did it by accident when messing with the linkage. Need to get a tach for my mini bike now. What are your thoughts doing this to the linkage and a zip tie on the spring??

This video helped so much. I definitely could not have done it the other way. I'm gonna try this as soon as possible. Thank you!

So the closer to the pivot the spring is, the higher the revvs?

can you tell me what is the best spark plug to run? I will be running a stock predator class at my local kart track

the governors lever is actually killing air flow to the carb when lever pulls the black piece on the carb?

Kart I'm getting ready to install a Mikuni VM on my Predator and this has me wondering: How can i govern the Mikuni?

Blown engines sells more engines! lol

I haven't removed gov but I have throttle plate and just removed that gov rod on a 420 cc so should I put it back and spring to get higher rpm

Can you do this with a predator 301

Just bought a brand new predator and mine is already setup this way. I went back to HF and the display model is the same as well.

one of the simpler mods very helpful.

can this be done on a 79cc engine ???

what happens when you just unhook the spring for the governor

right on 🖒 thanks for this.

what plugs do you use

+Kart I have stock valve springs on my predator 212 and have unhooked and secured the governor from moving but I am still only seeing 3600rpm, +/- a few hundred. do you think my stock springs are floating early? Idk what else it could be. it's like the governor is still intact. the predator 212 is on my vintage mini bike. both jets have been re-jetted, custom throttle linkage, no air filter, e3 spark plug, 1/2" to 3/4" to 1" custom header 8" length. I have not advanced the timing or swapped out oem valve springs, and have not replaced the stock e tube. finally, I am running a TAV20, do you think that could be limiting my rpm's? I would appreciate any input you can offer edit: I just read some more comments, one mentioning the throttle. I have verified that my custom throttle linkage is swinging the carb to WOT

Doesn't work

sick intro

Lol I've just ripped out the governor and rev it as high as it will go. Been like that for years on my mini bike and still hasn't blown. Sure throws fireballs out the exaust when I let off at max rpm tho

poooop
