Careful when the valve breaks off and you're taking the cover off. The valve spring might still be under pressure and it can launch the valve stem through your eye pretty easily..
@GoldGuy dude i just picked one of those up like a week ago. 2005 suzuki drz 125. Got it for $1270 really good condition. Changed the oil as soon as i got it.
Hey, great vid. You need to use motor oil that is for Motorcycles though. If you look on the back of the bottle and it says JASO MA then it's good. Automotive motor oil has additives that can cause the clutches to slip.
@@otto-pd3xv You don't need to oil an o ring chain actually you twat, the "Lube" just prevents rust. if it was an old style chain like is on my Mito however you do need to lube it.
The chain is really tight with no weight on it because the rear suspension is blown out, when the suspension is at full droop which looks like all the time, the chain loosens.
Klx 125 motors are strong as hell. My first bike was a klx 125L great first bike to learn to ride and to trail ride with. I ride a gsxr 750 now but if I were to ride on trails again I would probably buy a klx 140 I don't need speed on trails I need s bike I can throw a leg over touch the ground and rip up dirt.
@@BlackLung87 lmao rip up dirt was just a phrase. I don't need to be flying through trails. I understand the difference between bikes nothing to brake to me I'm not a new rider.
Should have cleaned that chain and sprocket up while they were off. Also I thought those engines take 850ml which isn't a full quart. Best to always just use the sight glass. Fill it up till you see it come up to the top line, then run the bike for a 5-10 minutes. Shut it off and let it sit for another 5-10 and check sight glass and add from there if needed.
@GoldGuy I ride every day basically. It's really a great beginner bike or just sonething too practice trail riding on. I'm not gonna do any performance mods too it. Gonna keep it stock. Maybe some cosmetics but that's about it
If the cylinder is fine you could just replace the piston and valves. And then use a dremmel to smooth Down the head. And make a aluminium plate and weld it on to the case to stop the leak. To me it seems like a waste of money. But i dont blame you for not wanting to do the extra work especially when you have the ts 185
It seems as though we are the last of a dying breed. I was thinking something very similar to what you just said. I try not to replace things unless they are missing or unsalvageable. Would have made for a far more interesting video, but as is the video was decent. Plus the people who gave him the bike for repairs likely payed for whatever parts were needed so I guess it makes more sense to go with the route that makes it easy for you if money is no object.
No way. That engine has small metal particles all in the oiling system. Youd need to pull it apart and clean cases. That head is fucked too. Cant just smooth out heads with a fuckin dremel all willy nilly. Dont spread hack fasle information.
@@saifsaid6705 i think a engine blown this bad would probably mess up the bearings and crankshaft buying a new engine would be cheaper in the long run and you have extra parts from the old engine
I can't believe you just let the engine hang there with nothing holding it when you were removing it, lucky it didn't fall, it would have defo needed another engine lol, tbh it would have been cheaper to split the engine and replace the casing and buy a new piston kit, a couple of valves and gained more experience. Small engines are a GREAT way to learn. Next time you strip an engine make sure you unwind or remove the Cam Chain Tensioner, it will help ALOT.
🤣🤣 I put my vailve thru my piston on my 200 three wheeler changed the piston and put a new head on her then the next day when mudding with her. Smokes like a train thou
you should remove linkage and swing arm before removing the engine this can be fixed easily no need to buy new top head , only it need new valve seat machinist can do that , and a new piston
I bet a with a new valve you could have ridden that bike a mile or two lol, but a new piston, valve and case would be a pain. My ct90 ate a valve adjuster recently and since it was a chinese replacement already i just bought a new engine like you did.
my friends bike broke when we where racing and the con rod went through the piston he needs as new engine because the piston exploded and destroyed the rest of the engine
That chain looks awful and the suspension dear lord 💀 Great work as usual man, I got a honda nighthawk I'm finally able to work on but still trying to figure out good welding placement, mind if I dm you through the socials for advice?
friends girlfriends son should have just taken a $1000 and bought a newer bike. Cause for the cost of the engine and other parts , plus your time, it would have been about the same and would have had a nicer bike that is not ready to fall apart on him.
If this guy puts it back together properly it won't just fall apart on him, heck I wouldn't buy a used bike on ebay without checking all the bolts on the bike anyway, at least this way he knows its been put back together properly, dirt bikes are absolutely abused.
@@thatwolffe3802 missed the point huh. He is not the owner. If you owned that bike and had to pay someone to take it, completely rebuild it, pay for all the parts and the labour you end up with a shit bike with a new engine. Or take that cash and buy a newer bike in better condition.
I just looked at some prices on ebay and a new piston + used cylinder head +left case costs around 200 dollars. Almost twice as cheap as buying a new engine. Or am i seeing something wrong?
My drz125 where blown the same way snapped exhaust valve Hole un the piston a lot of aluminium on the Botton and i rebuild it for 300$ canadien dollar with a chineese big bore kit nos its 150cc and have a high lift Cam
What a rat bike. If the kid can't look after it then why give him a bike, live and learn i guess. Edit: i own a 70cc pitbike, i abuse it but don't make stupid mistakes like running without oil and not looking after it.
This is no rebuild. Bike is neglected generaly. You just replaced the engine period. And you spent 450 for a part not worth that much. Also you could just rebuild the original engine. As i se all you need was new piston and valve. Head could easily be repaired.
no freaking way is that engine trash. go to a used small engine aka atv/cycle shop/yard and yet you a top end for like fifty bucks. bottem end is still good on the motor.
I know what you mean, I'm saying that 4 strokes have no sense specially on competition bikes, and specially if they have small displacement. Lots agree but it's most a matter of taste
No No No.... Looking from the "wrenching" you did, your boyfriends sisters, son is lucky you only replaced the engine and not did any actually work on it. Get a workshop manual. That is ALWAYS the corect way to start the work you are about to do.
I hate it when I drop a valve through my piston oh wait I have a two stroke
The good life
amen
I like my 4 strokes for lifespan tho. As long as you change the oil, they aren't bad bikes
X Alious but to make high power you have to put a grip of money into them
McNut same bruh
"This is My Friend Girlfriend Son's dirtbike"
;thonking;
That piston is awesome. Would make a nice trophy topper lol. Great job on that 125 👍
He said he drained oil and coolant to ship, seems like it's air cooled
Probably just a copy & paste sent with every engine he sells
WAW , this dude have blown up a 4Stroke.
Only that fact deserves a medal...
Well it was air cooled
The medal belongs to Suzuki, actually
Kos Tis I have a Honda xr100 and the same thing happened to it except the valve wasn’t stuck in the piston
@@technopanda1018 Then that medal belongs to Honda
Kos Tis nah not really you can blowup any bike if you try hard enough

"Is there even a piston anymore?!"
LOL, classic
Look how tight that damn chain is..to tight no oil,grenaded the engine and casing
Luke Short you don’t need to oil the chain you twat
@@OO-mo8mr you do twat
@@OO-mo8mr There is obvious rust on the chain, chain lube prevents that
@@otto-pd3xv You don't need to oil an o ring chain actually you twat, the "Lube" just prevents rust. if it was an old style chain like is on my Mito however you do need to lube it.
@@thatwolffe3802 you are twAT. O ring chain has oil inside but the surface still has to be lubed. The glue lube is used for that.
For the first second I thought you bought another bike already lol
No not yet 😂
You deserve more subscribers. this is the first video i've watched and you've got some knownledge and in the end you pulled it off. great video man.
The kids should be happy just remember to tell him to put oil in the next time or check it better yet show him how
well done for fixing the young blokes bike buddy ,,,,,,,Thumbs up !
You have a bunch of good parts still on the engine, tranny, clutch, carb. etc Good deal ...
Nice work! And wow, that valve-piston melding was insane
Your all right my guy.you just made some one very happy 😊. Your alright
Love this guy more each video.
"NO BUENO" 😂😂 So nice spanish dude😂👏.
Nice video!💪
11:17 never smack case/case covers open with metal tools, use a rubber hammer instead. Or a piece of wood between hammer and case.
That piston would make a great rear view mirror decoration.
Should of let of the timing chain tensioner.
Good job Sir! Excellent video! You just keep on gaining experience.
A good tip when pulling off a timing chain is to make it with white out so your valves open at the right time, other than that, great vid bro 👍
That is a good tip, but in my case that engine was trashed and is going to get parted out
Don't worry about that, the timing components all have timing marks on them.
@@GoldGuyRides for the info, all Suzuki 125cc engines are built by a Chinese company named Haojue.
The chain is really tight with no weight on it because the rear suspension is blown out, when the suspension is at full droop which looks like all the time, the chain loosens.
Man, there's a piston like that at the local scrapyard. Bad day all around.
Thanks man. Keep them coming. Nice job.
That chain is so tight. At least it looks like it.
Damn good video. Nice work

I mean yeah but I mean look at it she’s a bit on the clapper side I wouldn’t worry bout clutch plates

is that a motor rebuild video or motor changing video ?

just JB weld the piston too to fix the compression and a new valve lmao
Nice Work....

Where do I put my idle screw on this bike
How did that happen???? Just bought a 150f that did THE SAME EXACT THING! People don't know how to treat bikes
because u should change oil every 950 miles , and no one do that
The eBay engine looks like it just came out of the factory😯
I knowww! I got lucky

Don't use a conventional oil in motorcycles
Big bore kit
How the fuck do you drop a valve that hard that it lodges into the top of the piston? Damn man.
For God sake use fully synthetic oil!
Same thing happened to my bike except it put a hole in my piston
I’d rebuilt that easy and it would have been new tons cheaper than a used engine that u might have to rebuild anyway
I mean I thought it was gonna be bad, but dear god that engine has Ebola.
"Rebuild" all you did was just a engine swap and cleaning out the carbarator
jup was thinking the same thing ahh
I had a klx 125L if you have any questions i can answer to the best of my ability i put a lot of work into mine when i had it
Do you know of any Plastics for other bikes that will work for the klx 125? I'm doing a full build on mine

He is pretty old
Hi. Very good job you did there.. All the way from Brunei. Wondering where is Brunei? Search on Google Brunei Darussalam.
Not worster than my ttr 125 piston was pieces almost like the motor ate it
Did the kid spray paint the seat too? Jesus Christ dude. U needs just pull a good old gold guy revamp on the whole thing
Or it could have no compression because of a slight exhaust valve leak LOL
Looks like all u need is a piston to me..... the head looks good enough to run well.
If you watched the whole video you would have seen that the case is cracked too.
GoldGuy Ive welded plates to cover up the cracks on my pitbikes. Its very easy
It's that easy solder aluminium properly? Which device and how you do it @Noah ? (don't have inverter and only tried steel before)
I did the same thing the kid did🤦🏾♂️😂
I will take that old engine if you want to get rid of it

put some gas through the air box wat
Seen that 2 😂😂😂
you need motorcycle oil man, regular car oil will make that clutch slip like hell
No bafle
no freaking way is that engine trash. go to a used small engine aka atv/cycle shop/yard and yet you a top end for like fifty bucks. bottem end is still good on the motor.
thats the worst you've ever seen, because your young. I've had engines grenade and leave metal thrown across the hyway , lol
Wait drz125s are air cooled only?
Yes
Worst blown motor you’ve evere seen? Boy you haven’t seen much.
Great video 👍 Hey changed my profile ,, you sure I can’t ask you a question its a good one .
