It most likely blew because of the stock connecting rod. The stock oil scooper can shear off at high rpms causing and engine failure. That piece you were holding was the bottom part of the rod.
Threw the rod, caused by riding the bike for a long period of time, stock parts were not made to hold up for long periods of time with those upgrades, Usually with stage 1 you don't wanna do more than about a minute straight full throttle. If you want a reliable engine you need to upgrade the rod, flywheel, and rockers + springs, cam for extra power something light like a 265 cam
If you want all that RPM you have to build to support it. And keep in mind you were lucky to not be injured by the exploding parts that came out. Otherwise a pretty cool riding video. Could you do a video of the engine disassembly so we can see the damage?
U can no govoner and still be safe out here Compton we use 50 in back and 10 on clutch and u can throttle them and last long we’ll u can’t stay open throttle u have to let these motors breath
Probably ran it low on oil. That creates excessive friction,that creates extra heat, then you get structural failures in the heavy stress points in the engine. A.K.A. you threw a rod dude. Tjat chunk was the lower end of your connector rod where it bolts together with the rod end cap that connects it to your bottom end(engine crank) when y9u blow up an engine thats what they mean. Catastrofic engine failure in the bottomnend of an engine is as bad as it gets. Yor rod end cap bolts were probably over tightened so it was bound to happen eventually. Cheap parts in cheaply designed engines means its only a matter of time till something snaps or seizes and depending on where the damage is and how severe you can or cannot rebuild it. You need a new block and rod and with the damage that does you need to just get a whole complete engine. Put a good rod and piston in the next one and head gasket and itll run for many years.
That piece you picked up in the gutter is the crankshaft end of the connecting rod! Judging by how little oil loss there was, there's a real good chance, it ran low on oil.
I just seen your video that's a piece of the piston rod there can be a few different things that can cause an engine to throw a rod improper oil for that exact type of engine it over heating and to much ware and tare for what I hear is the most common but I am sure I am mistaking on that
Thats why i haven't messed with mine. The stock motor can't handle that high end rpm range or they explode. Most of the guys build the inside of the motor first
That is why you need a fan if it is summer that is why it exploded because rpm to high and to hot 👍it looks like the meatl is done get a new engine 😂😂😂
Will my stock predator blow up idk what my rpm is but I get 50 top with the governor bybassed (not removed because that’s to much for me) plus I deleted my jack shaft and am running one chain

A minute lol you're kidding😂😂😂
Thats cap bro ,its a hit or miss when it comes to 212 preds everyone i know been running gov deletes on stockies for more than year on same motor

How do we support it
@@braytonschneider40 billet rod, billet flywheel, and 20 pound valve springs
@@evilboy6693is the 196 cc parts compatible with the 212?
It’s the connecting rod you need to get a billet rod in a billet fly wheel and then you should be good that’s what happens on those motors
Connecting Rod Has Exited the Building
🤣 Nailed it
This is why I don't remove my governor. If you want better speed cut throttle stop screw and get bigger front sprocket +torque converter.
Exactly what I’m doing your so smart for understanding this will getting a better exhaust cause it too also blow up or nah
U can no govoner and still be safe out here Compton we use 50 in back and 10 on clutch and u can throttle them and last long we’ll u can’t stay open throttle u have to let these motors breath
Lower the gearing less stress it has on motor

This is good video to share to people to show them what happens to a engine without the proper mods. Good video! Sorry about the engine.
That, my dear friends is what's left/the top piece of the connecting rod to the piston.

No wonder it blew up bro doesn't know what a conrod is
you sound like a conrod. Thanks for the comment lol
Looks like the rod probably from lack of lubricant or old lubricant
Too many rpm and you killed the big end of the connecting rod, it seized on the crank and exploded.
13:45
definitely the stock cast aluminum rod. u need billet parts if u want higher revs and more speed
I think it overheated causing the cylinder to start to lock up with the the piston resulting in the connecting rod to snap off the crankshaft.
have u read the risks of removing the governor?
For the people that skip to when it happens it’s at 13:45
that's part of the piston that's the piston arm.
CRANKSHAFT THAT'S PART OF THE PISTON ROD
This is why you don't send mini bikes for hours a day. The engine prob overheated causing the piston rod to cease and then snap from the high rpm.

You starved the rod man.
The wild cat is here.
Connecting rod
needed billlet rod
Cool
Had you bypassed or removed the governor?

Talk about throwing a rod

It will

Where is the bumper part 2 man
haha sorry to keep everyone waiting on part 2. The 4runner has been sitting and I just got it fixed and drivable again. That is the next video
It’s that crappy cast iron rod.
What bike does that fuel tank come off of?
Its a generic ebay tank
Why not just buy a real dirt bike
Ive had plenty of real motorcycles. These are fun pit bikes to putt around on though
