Just got my first mini bike frame 2 weeks ago. Just finished doing my first governor deleted today and getting the engine running. This is valuable info as I know my engine won't be stock long. Thanks for posting
It would be good to inspect the inside bearing surface of the connecting rod. See if something jammed and then it snapped. To me it's odd that the first thing to break was the billet rod. Any defects in the metal where it broke? Sure blew up good. Good channel, keep the great real content coming!
was definitely thinking about getting one of these amazon rods for my budget 196cc build. now i’m not so sure anymore 🤣 sucks to see though, hope we see you with another engine soon
Those that mentioned the piston seizing makes most sense to me. I don’t believe in the idea of the rod just snapping, even if cheap china. I did have an ARC rod break on me, but I believe it got hot due to losing oil, and then I believe the top bolt lost torque and then the bottom bolt snapped causing a blown motor.
@@angelarobertson9424basically the momentum of the crank and flywheel spinning kept the force and it snapped wit all the force then a sudden halt to all moving parts
The end of the rod near the wristpin probably got so much presure from the comperssion that it just snapped after all the abuse, the rod is the most abused part in an engine.
Royal I have a question I’ve been struggling with fixing my bam breaks , so GTS said try a new tire that didn’t work then they said re wield , but when I came back they said BAM made the breaks too long , will a new break assembly from fast lane fix my problems or do I need a new frame ??? Help pleasw
I honestly cant tell yah what actually went wrong, maybe to much powa on the cam like you said, but a mild 265 or mod 2, and i heard jr mamba cams are pretty good. Anything stronger, should definitely get an ARC, but i been running this Amazon rod for a min, went through 3 sets of bearings, crank is flawless, ig i got a good out out the Amazon batch.
My guess is that the exhaust rocker broke causing the valve to stay closed on the exhaust stoke, the exhaust gases had no where to go and either the rod or the piston gave out first and caused the other to go with it. #boom
At this point of his building minibike engines and being on that circuit 24/7, it blows my mind that this seemingly intelligent young man takes the cheap way out everytime on 90 plus mph racing bikes. I made a comment like this on another of his videos and somebody replied to me and said give him a break he's still learning. Yeah, the first and last thing he will learn at 90 mph on scrub brakes is rule numero uno, you get what you pay for.
yeah but people just wanna do it for cheap, like me and my friend were building an engine on a small budget, using cheap parts to get the most performance possible, its just fun
@@syndeko1632 You gave a very intelligent reply to my comment, not only do I respect it but, I get it. The whole point of his videos is to try and do it spending as little money as possible.
The rod was still in one piece after the piston shattered,then the rod broke off, slinging the wrist pin around. And that part of the rod you see stuck causes the shearing off the shaft pin, in half.😏
Sorry that happened man. I bought one of those rods during the prime day sale. Going to do a review and put it here on TH-cam soon. Unfortunately when things look the same doesn’t mean they are the same. The extra $20-$30 is probably worth it to know you’re getting a good product. My gonads are too close to that engine block to run a cheap rod if you know what I’m saying.
Royal your buying up and building these engines. Filming is your key element bro...Snag up a tripod PRONTO! Quaility of your videos is what draws viewers homie. Spend wisely, Rootin for ya my man! My guess is they timing key snapped, then off timing you piston hit a valve and was all downhill from there. The billet rod did not fail, at all! I think key snapped or your piston touched a valve...
Was there a clearance issue clearing the rod and that 274 cam? I read in the comments,that people who bought the Chinese rod , couldn't get the wrist pin in the rod? Was yours real tight when you assembled it? Maybe ring gap was to tight? Low on oil? Just some possibilities?'i know youll build another one,and $160 wasnt to big of a loss.how long did it run before it grenaded? Was the engine warmed up before you reemed on it?👍👍
What a chain reaction of carnage. At the school of hard knocks this was a most valuable learning moment. Looks like the rod needs to be a notch or two more legit. Thanks for sharing.
So what would be the right thing to do if I want a safe trustworthy cruising set up for my mini? I want it to be able to do at least 60, I’m barely gonna get a 212cc so what else should I swap or change or buy?
I'm glad I live in Arizona because we have alot of 212 predator hemi and non hemi engine available to us. Better off to spend the extra cash for the high-end name brand parts then to get cheap performance parts
The rod looks perfect to be honest, the stock piston in the predators are known to implode at high rpm. That’s why you switch to a weisco piston, or use a forged piston beyond 8,000 rpm
Yo the method to get predator 212's in California is to buy the generators broken or used for cheap and swap the sidecase and crankshaft of the motor to make it work on the minibike
rip...thats wild cali stopped selling 212s!??! why emmisons ?!? i just got my 212 running..black mamba jr cam, arc flywheel and rod,moefab exhaust. Gotta find a way to get you guys some new 212s! What clutch is that?
Yup 100% was that chinese rod never again after what ive witnessed i have bought one for $45 and i had no rod bearings nor did my wristpin spin inside the rod and it had alan head bolts☠️ not even real rod bolts. Went ARC wristpin slid through like butter and it also came with rod bearings and real rod bolts🤌🏻. Never cheap out on whats inside ur motor..
i just hope no one else buys the china rods.. i did it the wanabe champion rockers...and didnt fit worth a crap...ordered real ones and huge difference in fitment.
It was defiantly the chinese rod i bought one before i built my motor it had no rod bearings nor did my wristpin fit in it😂😂 i hadda go arc been beating on my race motor zero problems. And it was my first motor build running stronger than ever. Dont use chinese rods/pistons they junk and they dont take the time to make sure the clearances are on point. ARC FTW🥇🥇
Why don’t they make steal rods for these things? I mean look at any motorcycle engine, those connecting rods can take an absolute beating and it’s very rare to see a motorcycle engine with a thrown rod
Wasn’t even the rod in my opinion should’ve went with a better piston. I’ve seen some people run Amazon rods with good flat tops and it run for a while
I think that the rod snapped in half and when that happened the piston was left behind sitting in the cylinder. After that happened the crankshaft and camshaft were still spinning so the valves hit the piston and when that happened the force of the hit caused the cam to snap and after that it all went to heehaa. Anyone else got something different?
Bro I’m in Vegas I’ll buy a predator 212 non hemi for you and meet me at the state line for retail don’t pay that crazy resell price lol and u stop at a Cali dispensary for me I need some za 😂
Litterly i had mine and i didnt even install it after i seen that it had no bearings nor did my wristpin fit or spin inside it got the arc rod pin went in like butter and everything went in smooth
@@Aces_crazykarti remember i did do it once it was running fine i started messing around with the carb because when i would go more than half throttle it would bog out i tried different jets and float levels but i made it worse now i bought 3 carbs already and cant get it running right now

piston siezed in the bore then the force ripped the rod apart then it kept banging in there and destroyed the cam and piston and skirt etc
The rocker must have broke after the cam then, think so?

makes sense. You think then the rod then hit the cam and made it break too
If it was the rod, the piston would still be in tack.Stock pistons are cheap, one small tinny crack,it will shatter.
do a amazon bilt hard 212 build

What type clutches do you guys use out there I'm watching from ga
What a chain reaction of carnage. At the school of hard knocks this was a most valuable learning moment. Looks like the rod needs to be a notch or two more legit. Thanks for sharing.
So if I get the right size camshaft will the Amazon budget flywheel and billet rod work fine ?
Have you ever been pulled over? What do you do if you do get pulled over?
Illegal to chase motorcycles and ATVs where I live so we basically do whatever we want. I imagine it’s the same in a lot of cities
You should twin charge a predator 212
Damn. I thought this series was gonna last longer
Looks like the piston went south and caused it all , that’s crazy

Do the stock rods break in the beam or bolt area..??
I bought one of those cheap Amazon billet rods and the wrist pin seized and shattered my piston
Rod or piston head for sure.. at least you didn’t get hurt
Nothing a little jb weld won't fix.😂
That's easy,JZ
The Piston blew up.
Not enough piston to head clearance
Hes at about .035, plenty.
224cc coming up or wha 👀
That is a chunky mess dude, very cool on your analysis.
Wait California stopped selling the 212cc ? At harbor freight ??
Wrist pin lock up maybe or is it free
And when it locked up, it twisted the cam, causing it to break in half...
BRO. That is the very definition of "catastrophic failure". Be safe running up and down Alameda and El Segundo, LOL
Piston probably failed way before the rod.

They banned the sale of all engines less than 25hp
Sorry to see you're engine popped like that but that's so impressive to see that much carnage out of a predator lol
I'm fuckin hollerin⚰️⚰️⚰️⚰️
We still have a ton of the predators in Arkansas you just need someone to mail you some 😂
Test your set up again with another block. ???
damn so im cooked
build up a tilly or ducar
When keeping stock rods would have been better. That blows!
Man I got the same setup minus the carb based on your Amazon build vids
Air cooled engines don't like Mobile 1
Their Teflon separates and wads up at like 280⁰, it's happened to me. Valvoline sae 30wt non synthetic only.
Sorry for your loss but thank you for showing us why not to buy that 65.00 rod
Total Carnage this is the worst I've ever seen wow thanks for sharing
What rpm were you running?
I didn’t have a rpm tach, so I’m not to sure
Can someone tell me why my predator 212 non hemp is smoking, when I give gas it blows smoke 💨. Does it have something to do with the piston rings?
Bad rings or the bore is damaged
0:35 my local harbor freight still selling 212s, just not hemis
1st and royal jz hoe much do you charge if I asked you to put sum parts on my bike
My new friend Egame is considering a Chinese Amazon rod and I'm trying to convince him to get arc billet parts
Wen is the next standard bore tournament big valve head
I’m not too sure
Noooooooooo now I see why everyone says don’t use cheap rods 😂
It wasn't the rod

EXPLAIN
Your piston rings touched you didn’t have enough ring gap
Seems like you were missing something or went to far on RPMs
The cause was the piston
Damn 😢
My man, I’m disappointed you even bought that rod
i just hope no one else buys the china rods.. i did it the wanabe champion rockers...and didnt fit worth a crap...ordered real ones and huge difference in fitment.
don't use aluminum for rods 😐 steel won't rip apart the same. aluminium constantly stretches and will break
