Finally, after watching countless RU-vid videos where people do not explain this well at all, I find your video. Excellent, detailed information. Thank you.
I am 55 yrs old with a wild side yet but due to severe arthritis I bought my mini to replace running my service dog as I couldn't walk him no longer daily. Your vid was very clear, and educational and well appreciated for a little lady still living life full throttle.
Bought the exact same bike with a blown motor i swapped a predator 212 bought a MTR performance carburetor and a aftermarket exhaust sounds amazing I’ve done 52 mph on the highway on it
Around the left side of the carb on the bike, there is a carb adjustment screw which is behind a cap that can easily be popped off and be adjusted with a screwdriver to fix the lean running condition.
I recently got a Motovox 79.5cc 4stroke for 250$ it runs perfectly brakes work everything is good i got around 23-26mph stock top speed, and i now got a straight pipe and gained 2-3mph, im watching this so i can get atleast 30-34 by taking off the speed limiter and the govnor to see if i can reach over 34mph this video helped me out so much, and by the way i raced a 212 predator, he got me at the start but i was starting to catch up thats insane idk how.
Change the spring on the max torque clutch to make it slip higher. You’ll need to remove the clutch , remover the snap rings (remember or video how it goes back together) and then remove the spring. Install a stronger spring to make it slip higher. The clutch springs are less then $10.
I didn't finish the video yet but most people don't address this. Make sure to tighten that throttle cable so ur take off and potentially top end is better. If u notice when ur stopped and try to use the throttle to take off, and it takes a lot of "twist" of ur throttle? It's bc there's too much slack in ur cable. I like to have it as soon as I even touch my throttle my bike is moving 👍🏽
Thanks for the video! By looking at mine i noticed also that the throttle cable was not even tight enough for the engine to get to full throttle, so i tightened that and unscrewed that limiter scew ( you dont have to take it all the way out, just enough so the moving parts dont hit it) and now my bike is waaaay faster. I dont think i would want it any faster. Lol 🎉
@@TeoVVS you wish buddy, not with all this Bidenflation. 💰💰💰 You ain't gonna find one complete and running for less than $200 and if you do happen to find one on the cheap you are extremely lucky.
The problem I’m having is my throttle works but doesn’t accelerate it. I’ve tightened it and messed with it but from what I can tell is it’s my rpm limiter aka that long metal rod going up to the carburetor. It stays wide open.
Dude the christmas ornament metal really works dosnt dropoff any more foes full throttle foreever and the air box hole made mine run so smooth qnd fot it over 35 mph great vid
update: drilled some holes in the airbox and it did nothing. just looks uglier and is prone to getting dirt and water in the airbox and making your filter dirtier faster. DON’T DO IT, WORTHLESS MOD
I want mine to do about 40-45mph and my bike i took off the air box off and zip tied the filter in. I replaced my throttle spring i never thought about the little piece of metal for the governor. Good information
Had a friend stop by today with one of these said it does about 40 miles an hour I think it feels that fast to her but I knew how to do all this but this was a great video and awesome video especially about the governor a lot of people don't know that happy holidays Merry Christmas my friend 👍🏽💪🏽👊🏾💥💨💨💯🎩
For anyone watching this, that big lever does not control the governor. I have fixed one of these bikes up and inside the crankcase there is a plastic gear, that is the governor. If you wish to gain a lot more top speed other than putting an unreliable paper clip on the carburetor lever is to drain the oil and remove that screw. That lever he says that is the governor is the carburetor lever, so when you pull the throttle that lever punches the carburetor door open allowing the fuel mixture into the engine. Please do not drill out the carburetor holes, this bike is a 1 cylinder and only air cooled, so if you are putting to much into it you make blow the engine up on a warm day. If you would like to do real modifications and not hurt the engine, you might want to look into getting a higher displacement bike. I left this comment here so that some kid watching this can’t get hurt and won’t get his dreams crushed when his mini bike has a hole in the piston. I don’t mea to diss Ty’s Tech but this is rather unethical. This bike also may not have correct tires on there to attain this type of speed. It also may not be set up to go this speed such as the crankshaft, camshaft, the bearings, the chain, and the wheels themselves. So please if you are looking to get more speed out of your bike you may have to do some shopping to keep it safe at all times. Such as purchasing some street tires to go on the street, perhaps buying a predator 212cc, maybe some higher rated bearings and a thicker chain. Also don’t mess with the brakes unless you know what your doing. Stay safe!
3:05 if you mess with the governor, your flywheel will blow up. Get an aluminum flywheel and get rid of the cast iron. The cast iron flywheel will blow up, destroying the engine and also could hurt you while riding.
I still dont understand how does adding the green wire makes the bike go any faster. There's already an existing wire there so why does adding the green wire make any difference? I read this entire thread and i'm stilllost. I tried added the addtional wire and gave the bike throttle and everything seems to be moving the same.
@Sivphui ngan my bike does the same as you describe yours does. When the bike is off, the governor arm moves with the spring that's already there when I give it throttle. Tomorrow morning when ib turn it on & maybe there is a difference when it's on or off.
I have to correct you on the Governor internally the the gear has weights and when the engine rpm exceeds it’s limits the Governor arm kicks the weights open causing the engine to slow down. Pulling open the throttle all the way without the engine running doesn’t effect the Governor. I have a tip remove the Governor by opening the case and taking a punch to the gear on backside and pull out gear arm and washers. Many people open them up and screw around trying to get the c-clip off when you can use a punch and the arm will slide out without cutting it. Yes I’ve worked on many engines and still do.
@@dauntlessentertainment4922 it was running great, I live in Minnesota so I can’t really ride right now because of snow. But it was reaching like the 40mph range. And it still runs like I bought it yesterday. I’m definitely getting some kits to make it go faster next summer.
@@Erik0824 That's great to hear! Did you do any mods like govenor removal or just leave it stock? (Sorry if I asking to much, I'm new to 212's and mini bikes)
I did all of the mods in this video. I topped 35 MPH. However, the engine fell apart and broke internally as I believe it couldn't handle all the pressure. I now need to get a new engine.
I got one of these for 60 bucks from somebody that kind of looks now like a Indiana Jones bike but I actually took a small spring since it's already a lock washer at the chain tensioner and put it between the bracket and then the lock nut so now I have an auto tensioning one it works
Hello how r u? I have a realtree 100 min bike is there anything I can do to make it go faster without removing the governor. I would be intrigued to know this is my frist min bike. I'm learning
My engine starts but when I go up a hill it cuts off then when crank it up and drive it only needs a straight road it only stays on for 5 seconds then shuts off. I haven’t change the oil ever since I got it in 2016
I bought one of these for my son when I bought a Baja 200 warrior I had a stage 4 predator I built and put on the Baja took 196 put it on the moto 80 sold the motor to my neighbor for a tiller he was working on
I can't speak for the 80cc but I have the 105 and it did 29 out of the box. They are only supposed to do 24 but I'm thinking the governor wasn't engaging all the way or something. I bypassed the governor and it now goes 35. Usually when you bypass the governor, it will increase by around 13 mph but it was already doing 5mph more than it was supposed to be doing and I weight around 210lbs. I'm going to do some more mods like carb and exhaust.
Yes, I have a mm105 and I didn't like the speed of it so I took a pair of needle-nose pliers since there's two spot welds holding the spark arrestor in, I just grabbed it with needle-nose pliers and stab the hole in it and ripped it out in pieces and it made my engine a lot louder and faster
There is a rubber tensioner on the bottom side of the chain. Just loosen the bigger 10mm bolt and then tighten the smaller 10mm to tighten the chain by pulling the tensioner closer to the rear tire , thus resulting in a tighter chain. Then tighten to bigger 10mm to lock it in place.
"that screw" (on the governor) is also to prevent strain on the carburator by limiting travel of the linkage. Also, it throttle plate can over travel, over travel is actually closing the throttle. Higher octane gas is actually lower power, but a higher octane prevents preignition, and these tiny "industrial" engines don't have any preignition concerns.
Higher octane isn't "lower power" it's just more stable under high cylinder temps and resists pre ignition or knock. Any engine can suffer from preignition and if you've modified the governor on a small engine to increase the redline then you will have a higher dynamic compression ratio, more advanced timing and higher cylinder temperatures which could definitely justify higher octane fuel. It's all trial and error but making blanket statements like that don't help anyone.
@@MegaDysart lol, you're very dumb. "The other rarely-discussed reality with high-octane fuels associated with "high performance" is that as octane increases, the specific gravity and energy content of the fuel per unit of weight are reduced." en.wikipedia.org/wiki/Octane_rating#Effects_of_octane_rating And you are not revving a mower engine fast enough to effect "dynamic compression"! Hahahahaha!!! Where the hell did you read that? The faster an engine revs the less air it can suck in because of the intake restrictions. That means a mower engine has the highest "dynamic compression" when you pull the starting rope, since the governor is holding the throttle wide open. You're just inventing reasons to justify putting 93 in your go kart!
Don't do this unless u plan on getting a new engine because it fried my rings and exploded my governer which the schrapnel destroyed everything else just make it simple and get a 212
The governor outdoes the spring and makes it drop throttle from the carb to the engine so it dosnt go to higher rpm but if u put a solid piece of metal itll stay full throttle forever and get to higher rpm and outdoes the govenor
Hello, thank you for doing ur video, it was very helpful. I have the electric version of this mini bike. Can I make the same modifications with the taking out the screw and the spring. Lmk thanks
My son moto bike won't start it cut off I changed the spark plug clutch every thing I even spray starter fluid on it made it start drove it up the street cut off again
@@TysTech i have a the same bike i just got a smaller sprocket which is a 36 tooth and 41 chain and a new clutch im doing 50 with a lil work done to the motor im doing a good 50-53
Ty's Tech then the idle will become too high and will pull on the clutch ( my dad did it and the bike started rolling and also it can lock up and the throttle won’t stop)
@@newgeneration1540 he has a small ass back sprocket but the down side to that is that it takes him 10 minutes just sitting there at full throttle to reach those speeds
I paid $50 for mine in mint condition. The old guy had no clue what it was worth. Installing a predator 212. Got the bike all gutted and governor gear has been removed on the 212cc. Just waiting on the mounting plate and smaller rear sprocket.
If you upgrade to a predator none of this applies. I'm in the process of changing mine. Already pulled the governor out of the engine. Waiting on mounting plate and smaller rear sprocket because it will pull the front wheel up instantly.
It still takes off very slow. Instead of spending a couple hundred bucks to make it fun, just buy a 6.5 Predator. It will do around 50mph with it stock and you will only have around $200 in the upgrade. ( motor, clutch, and chain.)
Do NOT bypass the governor, you must remove the plastic gear inside: The governor gear it's well known to tear apart at higher RPMs and spread bits of plastic all over the crankcase, in addition, it has metallic components which may jam into your timing gear; take your time and remove the plastic gear inside, there are plenty of tutorials around RU-vid.
@@wisehumbled5027 Sadly I don't think it's possible with this type of engine, but with a Predator 212 or 420 it would be possible: It'd be wise to swap the stock connecting rod with an ARC billet one: Without governor, the rod may shatter, as it's not designed to operate to higher RPMs. The push rods may also bend, and the cast iron flywheel could also throw the magnet or even frag out, so consider chromoly push rods and an ARC flywheel if you want to go hard with a 212/420.
