Thanks mate, I got caught buying a 2nd hand 230 crf for my son...had it a month and the thing started smoking like a hippy at a Bob Marley concert. Took it to the local Honda dealer.....and bang....sir your quote is $5000....everything is fucked they reckon.....well that is little more than twice what I paid for the thing....I told them don't worry about it I'll do it myself. The icing on the cake is when I went to pick it up (in pieces) the mechanic offered me a carton of beer for it.....what a fuck'n liberty! So I will do it myself.....and like you have shown in your video...some bikes you just need to get up and running again....they arn't worth a lot and you don't need the rolls royce service on em...just want em working again so you can use them.
Hello, just want to comment on how you and the young guy (your son I would guess) are working together. And the respect and patience you show in helping him. My dad never had the patience so we didn't do those things together. It's nice for me to see that fathers and son's can work together like that...good dad
+Nick Nicoloudis hi Nick .my piston is seized in the barrel and im gonna have to knock it down somehow ,but then it wont be in sync with the valves? i dont know how im gonna do this .any ideas?
Good job, worked fine by the sounds of it :-)) Reminded me of the old small honda's of my younger days, same chain tensioner system as some ive tinkered with. I used to make base gaskets out of cerial boxes, i didnt have much money eather.
Dear Nick, I do not fully understand your explanation on the valve clearances. At what clearances have you set your inlet and outlet now? Thanks for the great video!
This is an Apollo 250 bike if anyone wants to know. Thanks for the video, Ben thinking of putting a new head on mine, wanted to see how aggravating it was to do.
FUCKING THANK YOU!!!! JESUS CHRIST WOULD IT OF KILLED A CUNT TO SAY WHAT THE BIKE ACTUALLY IS @RCflightSeeker . thank you so much dude saving me heaps over here I just braught one of these I've had to try and re-wire the fucker as it's been modified by some asshole has just screwed it completely so I'm in the middle of rebuilding an it's just been a real shit show brother so this has helped me out so much I now actually know the things I'm looking for and this is gonna help out heaps
Good job, but it will be good it you follow requirements of the engine manual, because as I know some consumable materials needed to replace during their removal. Best Regards.
I've got one that's heat seized. Assume I need to get the head skimmed before refitting as well as new barrel and piston? Like the way you dropped the engine without having to take it out, very informative. Thanks.
This looks like the 229cc I have on my 2016 magician I was riding earlier after I changed oil and it got choppy then died when I pulled the clutch. It was leaking oil like a sieve but started once cooled down. What's the problem u think?🤷🏻♂️🤷🏻♂️🤷🏻♂️
Hello. I have a zongshen 250 dirt bike and I need a replacement hub and rear brake rotor. I was wondering if you could help me find one. I haven't had any luck. Thanks
Is is a movie , as in this engine properly set the timing ? Where you put the cam , up or down? After setting the timing chain tension ? Sorry for my English, but I explain in google . Regards.
Does anyone know how to mount the cam chain on a zs169fmm machine, the piston is 69mm. I have a chain of 102 links and 104 links. 102 links are too short and 104 too long, regardless of the tension in which phase it was. on the 102 link, it needs a little bit to sit, but I'm afraid that it would be too tight and could damage the camshaft bearing. by the way, I don't know if it is the original cylinder on the machine, because I read that the piston should be 65.5 mm.
Does anyone know what a good compression test reading would be on a cold engine? I'm trying to figure out if I need to tear mine down. I got about 135 cold without adding any additional oil to the cylinder head through the spark plug hole.
@@M-Revs You have markings on the side of the clutch that allow you to bring the camshaft back into position by finishing flush with the edge of the cylinder housing with the markings of the camshaft gear
gasket is worth more then the bike, but you can just use silver paint from spray can, it has small metal fragments in it that will fill the imperfections
unfortunately most of these bikes dont have timing marks so you need to do it yourself. need to be scared. just turn it over by hand from the crank. this way if it gets stuck somewhere you know it's not right and just do it again doesn't take long. don't use the starter motor. and have fun

+GAR A I know how to find out if the piston is on tdc (Top dead cernet) and not on bdc (Bottom dead center): take the spark plug out and look inside to visually check that the piston is there. if you cant see anything it maybe because the top of the piston is black. in that case just stick something inside to feel the top of the piston but be careful not to drop it inside the barrel!. if you have done it wrong the bike will probably still start but be really noisy. if you notice this, open the valve covers and search tdc again. The valves clearances will be REALLY BIG, adjust them again. that is definitively tdc. it is good to always take the spark plug off when you do this anyways because the engine is easier to turn. I think the valve clearance would be more accurate if the engine TDC is set turning the crankshaft in the same direction as the engine normally turns as it normally works (that is the oposite direction the mechanic from the video does it) I have done it in 3 different bikes and i think it would usually be anti clockwise in probably most bikes If it doesn't have any marks on the crank i would imagine that something somewhere would align somehow, like the bolts on the timing chain sprocket in this case?
moe green guess what....when your an experienced engine builder ....youll see black blowing past the compression ring....this is the tell tale sign the rings are bad...youll also see black on the skirting of the piston.....but you would not know that...cuz you've never been inside an engine......you have to realize this engines worth about 250 us dollars......so you have to weigh the cost of service to the value of the product....would you put 300 dollars into an engine worth 250...no...here in USA an hour of a mechanics time is roughly 100 dollars...so 1.5 hours and your at 50 percent total value.....it does not make sense to do a documented blueprinted build on this engine
styles,unlimited I've rebuilt countless motorcycles and ATVs you were partially right on what you say but not 100%. I've only built 2 Chinese machines a 110 and a 70 cc. Most Japanese engines the valves are shimed nonadjustable replace shims only
Look at the dent in the piston from the exhaust valve hitting it. LOL. Look at the exhaust valve spring when he puts it back on. It's crooked because the valve is bent from hitting the piston. This bike is fucked. He did not even check anything. Didn't even use a cris-cross pattern when putting the head bolts on, much less use any torq specs. Good way to warp the shit out of the head.
No new gaskets?, no torque check, using a blunt metal object on head surfaces, what gives dude?? as I see this, if I didn't know how rebuild an engine and watched this for the first time!, wow.. I'm surprised if it ran after this, very poor video tutorial
you can slap these chinese engines together if it was like a cbr 125 engine i would have set it all out on a white table and had trays and torque settings and a set of new gasket with copper sillicone
kierankay100 That attitude is why Chinese engines keep encountering problems. Treat em like any other engine and they're not a bother. Did a top-end rebuild on my Chinese 125, treat it like I would any other engine and she ran smooth as ever.

Smoking = Usually just means it needs new piston/rings. $100USD fix.
Amazing... I've been looking everywhere for videos, parts, etc. for this bike. It is the same motor as my ZS250GS Storm. Thank you!!!
Hello, just want to comment on how you and the young guy (your son I would guess) are working together. And the respect and patience you show in helping him.

Hahaha I'm here working on the exam same engine without my dad :(
Good job, worked fine by the sounds of it :-))
Reminded me of the old small honda's of my younger days, same chain tensioner system as some ive tinkered with.
I used to make base gaskets out of cerial boxes, i didnt have much money eather.
hahaha. the Chinese have copied the Honda engine. I have head of using cerial boxes for gaskets. have not tried. will do :)
I have the same dirt bike engine that propley need a topend rebuild thanks for helping
My father had no clue, so I just took the bike apart myself, it still is the best way 50 years later, and 50 years later I'm still doing it....
Dear Nick, I do not fully understand your explanation on the valve clearances. At what clearances have you set your inlet and outlet now?
Thanks for the great video!
Apollo 250 let's get it brother dope and well done

wow how is that piston top so clean, when i look at mine through the spark plug hole its just black not shinny like yours.
thank u so much for the show of the engine i need (y)
Good job, but it will be good it you follow requirements of the engine manual, because as I know some consumable materials needed to replace during their removal. Best Regards.
Dude your are the best
Η καδένα χρονισμού είναι ότι πρέπει για τα κλειδιά ^_^

I've got one that's heat seized. Assume I need to get the head skimmed before refitting as well as new barrel and piston? Like the way you dropped the engine without having to take it out, very informative. Thanks.
That Piston is Brand New never Fired- No Soot or Oil Deposits! -Someones Already Been into this Motor!
Saved me a lot of time and money with setting up the engine timing chain
Not a single new gasket was hurt that day, and no torque wrench got disturbed neither.
This looks like the 229cc I have on my 2016 magician I was riding earlier after I changed oil and it got choppy then died when I pulled the clutch. It was leaking oil like a sieve but started once cooled down. What's the problem u think?🤷🏻♂️🤷🏻♂️🤷🏻♂️
The same principles on this thumper apply to a vtwin yes?
very....very nice......congratulations...... São Paulo - Capital - Brasil
Hello. I have a zongshen 250 dirt bike and I need a replacement hub and rear brake rotor. I was wondering if you could help me find one. I haven't had any luck. Thanks
New gaskets wouldnt be a bad idea
I see theres no plastic guides for the cam chain, the one i have has guides i was womdering if the chain is tight can i just remove my guides ?
Dose that say “in” on top of the piston?
Is is a movie , as in this engine properly set the timing ? Where you put the cam , up or down? After setting the timing chain tension ? Sorry for my English, but I explain in google . Regards.
Is this almost the same for every 250cc 4 stroke single cilinder engine?
Needs to be a rtv comercial

Very nice video Dost
I recently bought a 2nd hand bike and it has the exact same engine you have but I don't know the name of it can you help me out please
what is the torque of the cover and cylinder? i have zongshen 250 engine..... PLZ answer me!
hi I would like to ask how many articles has rozvodová chain thanks in advance
Can show how to overhaul an loncin gp 250cc step by step thank you
After rebuild it how many km we have to ride below 40-50 km....
Got a 3.5 straight 6 lotus carlton engine here that needs the crank regrinding , could you give me some tips .. ?

If its a 250 like in the video, 135 is around how much it should be, your engine is good to go 👍
Can u make a video on tdc
Can you please send me your wiring diagram i have the same bike but messed up wiring
What bike is it
Great
Is that 166fmm loncin motor
Piston 65,5mm x 66,6mm ?
hi there.after the modification you did on the camshafts,how the engine perform? is there any difference? is it better?
yes, a big difference a lot more top end. not good for dirt bike, but good for road bike :) higher top speed
Nick Nicoloudis THANKS.
What brand is the bike. I have the same bike and I'm looking for the cover plate and starter motor.
atomik xr fury 250cc got one meself
Didn’t show putting the rockers back in
Y cuál era el problema????? Sólo desarmaste y volviste a armar como para que??????...
how can i repair my gear
حُلُوَوَوَوَوَوَ
روعه
Looks like stop motion
Hello bro,
Hope you are doing well
I have this engine..can you please tell me how much HP does this engine have?and what brand is it?
These are zongshen engines made in China. They range from around 16 to 19 horsepower depending on the exact model.
Hello, I have a question, I have the same motor, How do you adjust the camshaft correctly? Best regards,
Did you figure it out ? Same sitautipn i didnt mark marks just took it off dont know where to put back now
@@M-Revs You have markings on the side of the clutch that allow you to bring the camshaft back into position by finishing flush with the edge of the cylinder housing with the markings of the camshaft gear
@@spartangamingandrecords897 so does fl on cam have to line up with the fl on clutch ?
Where does fl on the camshaft have the line up with
@@M-Revs exactly. 👍
I got an yamaha dirtbike but no engine what do i do
Bus Driver better put some heavy duty pedals on that bad boy.
what exactly you wanted to show?? how to remove and install cylinder?? and why you dont use new a gaskets?
gasket is worth more then the bike, but you can just use silver paint from spray can, it has small metal fragments in it that will fill the imperfections
Nick Nicoloudis any silver paint works?

This engine is not a 250cc engine but a 230cc Honda engine.
sl230 & FTR It is engine used for motorcycle.
It must be cleaned before assembled...
Rockies toad side repairs and Frankie's farm house fuckups! Ok on a Chinese bike.
pliz help and teach me am intrested
also there is a torque sequence to those head bolts and you sure didnt follow it
If i put regular gas in a 91 yz 250 what needs to be done.???? Anyone with knowledge please comment
Drain all the gas and put 2 stroke mix in it. Unless you already blew the bike up
You didn't rebuild nothing take apart and put back together, WTF?
how do you knew its not Bottom dead center? i am scared i might put it on BDC instead of TDC
unfortunately most of these bikes dont have timing marks so you need to do it yourself. need to be scared. just turn it over by hand from the crank. this way if it gets stuck somewhere you know it's not right and just do it again doesn't take long. don't use the starter motor. and have fun

what the name of this bike engine,not totaly same to hero karizma engine👍👍
Zar Mawia it's a lifan engine Apollo made it
Or I can find the piston and cylinder
which engine name

loncin re250 engine. same as mine
start white out a axhous man thouse valves wont last long
Stuck gasket
Is this engine is honda
Clone of the crf230 motor
مرحبا بكم
this is not a proper how to video
lol didnt even mention what engine...
Needs more performs brothe for better videos you don't explain position on piston and rings
How in the world do you build any engine and not put new gaskets back and torque the bolts correctly this is SOOOOOOOOOO stupid
This is a basic re ring and yeah it does work just fine
This is from some one who gaffer tapes their frame? Yeah do one newbie!
