+Monique Gilmour you align the "T" mark on the ignition with the notch in the crank case. Once that is aligned, you take your cam sprocket and align the dot on it with the notch in the cylinder head.
problem, taking mine apart and as i turned engine over a small spring and small metal cylinder fell out. it fits snug in the centre of the clutch but not sure if it goes there what u think
I have a question. I have a Taotao with the 125cc motor with the kick start. But it wont crank up when I try and kick start it. The motor runs fine but it just wont start like at all unless I take a running start in first gear. Could it be the starter thats messed up in if so how do I tell if its fried?
Excellent video. Subscribed to your channel. I have an issue with my timing chain its creating too much knocking noise and is a bit loose. I m suspecting something is wrong with its cam chain tensioner. @11:47 when you were assembling it by inserting the rod you the holes in the rod were in one particular direction can they be in any direction? Or is there any notch in it to avoid incorrect instalation? Any video on just troubleshooting loose cam chain?
Hi i also have similar engine. I had problems with oil flow. There was no oil flowing to the intake rocker arm. When I opened the engine the oil screen was totally clogged up. While I cleaned it I checked the oil pump sprocket on main Crank shaft as shown in @2:05. This sprocket is rotating both clock wise and anti clock wise. I don't know when crankshaft is rotating whether and how this shaft rotates. The metal sprocket on crankshaft that drives the plastic sprocket of oil pump is free. There is nothing to bind it to the rotating of main crankshaft. Engine is dj 154fmi
Chamjisky Khan I think you need a new engine case broths because it's not supposed to move counterclockwise only clockwise now don't get me wrong that is really the only thing that's running your motor like the can shaft inside and the cam timing if it's set incorrectly you will get the oil problem you have because everything in the engine depends on each other hopefully I kind of help you bro sorry if I was just talking crap but if your saying it moves back its fine while not driving or operating it you should be good but that oil pump is serious because If no oil is moving around the lower back of the engine it can fry the engine pretty fast so what I would do is call the company that made your bike and tell them what is going on or call your local dirt bike shop
can you pleas show in a video where al the washers should be in the engine . and olso when i kik the rotor set dont rotate ? can you help me with this problem ??
Hi. I really liked your video, thanks for sharing your knowledge and experiences. Nestitary help to know where to get the tightening tool for the crankshaft nut, in the part of the clutches. Thanks greetings.
yes it was after when i was at high speeds then i heard it and felt it i had recently adjusted the valves about 1 month early they we WAY OUT of adjustment to where i had to push start it about a week after they were already out of adjustment again. so i dont know what is wrong with it maybe it is even the cylinder hitting the wall?
Rebuilt my engine very similar to this one and the piston goes up and down if I spin the flywheel by hand but my kick starter is jammed any suggestions?
The piston has to be at TDC then mark the case and flywheen where TDC is then the cam gear should have a mark that should line up to the left 9 Oclock if you will and thats it i think
the clutch plates and clutch is on the right side correct if I take off the right side cover is everything in place meaning if I take it off nothing will move out off place and break because my clutch plates are either sticking or burnt up I can't shift with my hand clutch it's useless I was cruising doing 50 MPH yesterday and I came to a red light and the bike would shift down or stop so I was pissed I had to walk home from there were it happened it was about a 5 or 6 mile walk home because I didn't want to do more damage than it already has done to the clutch itself
i have a 140cc lifan engine, when i put all the gearbox parts togheter its spins freely, when i turn the selector and try to spin the gearbox, they make a bad sound and one of the sprocket si moving up and down, anyone know why ?
Hey, I recently changed out my left crankcase due to a crack and then when I pieces it together I Realized that my clutch didn't have full movement (it could move but lost 75 percent of travel). I didn't put oil in it yet just to see what you guys think. Could it be the lack of oil screwing up the wet clutch travel or something else? Thanks
if you cant find timing marks what i do is turn your crank untill piston is at top dead center l ready to induct and mark your fly wheel turn your cam shaft untill it is just about open the inlet valve when you put the chain back on it should be about there give or take a tooth but as the piston drops the inlet should be open
I have a black washer that says "side out" that I'm pretty sure came from the clutch side but i can't for the life of me figure out where exactly it goes
I'm not sure what you mean? The crf50 style engine is one of the best ever built but its a very basic design and everything is made to work together as a unit.
Kiko Neviem all Chinese pit bikes have a lifan engine they all are the same for the ssr, Apollo, roketa, bbr , and so on in the 125cc I'm not sure about anything above it but for the 125 cc then yea they all use the lifan engine they may have different companies that manufacture the engines them selves but they only engrave there companies name into the the cylinder side cover or the right or left side cover so that it is more nice looking but a lifan engine is a lifan engine they all work the same
This is the most instructional video with no narration I've ever seen
Thanks bud, my engine did the same shit. You've given me newly found confidence in this simple task for any beginning mech
mate this video just saved my engine!! thanks
That was a great help I'm ready to build one now the Only thing I didn't get is how to set the cam timing 😁
+Monique Gilmour you align the "T" mark on the ignition with the notch in the crank case. Once that is aligned, you take your cam sprocket and align the dot on it with the notch in the cylinder head.
what is that hose sticking out of the engine at 0:02?? and what do i do with it?
problem, taking mine apart and as i turned engine over a small spring and small metal cylinder fell out. it fits snug in the centre of the clutch but not sure if it goes there what u think

is there not a spring and a pin that goes in the bearing on the clutch before you put the cover on??
Chris Reid yes there is
Why does my engine run only without the top head/camshaft valves? Once I put the timing chain on top head it won't turn over.
Nice video! Hey can you please do a video about how to change the gears step by step starting from taking the motor off the bike?
do you see the little pipe coming out of the top where does it conect to if you or any one else noes i would be greatfull thanks
how many 5:24 clutch lamels?
aye if i take the whole enegine apart and put it ib gas and buy new rings and seals do u think it would fire up if i put it back together
very good hoping to do this with my lifan there pretty much the same engines. did u get the bike going again?
Where can I get the gears for a 125 Chinese loncin pitbike manual kickstart plz help!!

Thanks I figured it out. Once the clutch basket is tightened then it won't move. And it will only move with crank shaft.
Chamjisky Khan huh
Chamjisky Khan oh lol
Chamjisky Khan no bro
can you pleas show in a video where al the washers should be in the engine . and olso when i kik the rotor set dont rotate ? can you help me with this problem ??
How do u tame the gears when rebuilding ?
change the oil on my pitbike now it won't start sounds like needs to bill compression how do I fix the problem
Sir many apney hero 72cc my bore karkey 150cc ka piston lagaya hi.ab 80speed tak gate ha. Or speed increase karney kaleya kaya karoon. Place replay.
Hi. I really liked your video, thanks for sharing your
knowledge and experiences. Nestitary help to know where to get the tightening tool for the crankshaft nut, in the part of the clutches.
Thanks greetings.
there is no rods in these engines its over head cam it still might be valve knock did you adjust your valves since?
Did you apply the rubber o-rings on the cilinder and head?
Can someone please help me find a big bore kit for a 125cc Coolster pit bike?? I can't find one and i'm really wanting to go to 150cc
yo i have the same, probably best off getting a 140cc with oil cooler and swapping that in
How is the clutch connected to the cable
Would u have a idea why my py 90 there smoke coming from my side case just up were the gears are
I've got a stomp 125 engine in bits, I'm just missing my clutch? Is it the same clutch as on the video??
Whats that black part at 2:49? what does it do??
Daradue sandstorm
Zi9makin9 did you ever figure out what it is called?
markunit72 Nope :/
Zi9makin9 my engine is missing it, and im like what it is called...
Ah man that sux! I just wanted to know about the peice if I´m gonna disassemble my engine sometime
Please how many teeth timing chain and if he would be a service manual
does the power band help when you torque your bolts
+Nick Ranthum yes
yes it was after when i was at high speeds then i heard it and felt it i had recently adjusted the valves about 1 month early they we WAY OUT of adjustment to where i had to push start it about a week after they were already out of adjustment again. so i dont know what is wrong with it maybe it is even the cylinder hitting the wall?
hey i took my 110cc through a creek as in my profile pic and after that the engine is knoking any ideas i think its the rods maybe???
what type of motor is this ? I've just gotten one but don't know what brand
take the pipe and run it to the bottom of the engine where it will not get too hot, its a overflow or breather for the crank case oil
Rebuilt my engine very similar to this one and the piston goes up and down if I spin the flywheel by hand but my kick starter is jammed any suggestions?
what is old broken gears for? can it be not putted on?
Pat Weng If it's broken it's not going to work is it? That's why he was replacing the gears, bless.
The piston has to be at TDC then mark the case and flywheen where TDC is then the cam gear should have a mark that should line up to the left 9 Oclock if you will and thats it i think
Awesome video,how did you learn to do all this?
is it on start device rod and washer?
What is the name of the part at 5:50?
Could someone please give me a link or at least at tip to were i can find one of these gearshift drums?? I can't find one anywhere!! Thank you!!!
the clutch plates and clutch is on the right side correct if I take off the right side cover is everything in place meaning if I take it off nothing will move out off place and break because my clutch plates are either sticking or burnt up I can't shift with my hand clutch it's useless I was cruising doing 50 MPH yesterday and I came to a red light and the bike would shift down or stop so I was pissed I had to walk home from there were it happened it was about a 5 or 6 mile walk home because I didn't want to do more damage than it already has done to the clutch itself
Perfect. Its all about an engine no crap talk about what's to come. Is your gearbox 1 down 3 up cos its very similar to mine only mines 110..?
What

hi what is the proper position of piston ring.
the crank breather? it doesn't get connected to anything. It just vents
I have a put bike but its hard to kick I don't know what's wrong. Do u know what's wrong?
Yo. That power band mate
Hey you need too adjust your clutch cable,your bike hasn't lost any compression its just your clutch being pulled it too much
How to set the kick stator to be in the correct postion??
Hey,
I recently changed out my left crankcase due to a crack and then when I pieces it together I Realized that my clutch didn't have full movement (it could move but lost 75 percent of travel). I didn't put oil in it yet just to see what you guys think. Could it be the lack of oil screwing up the wet clutch travel or something else? Thanks
No it's a fitment issue
can you put a 200cc cylinder body and head on a 125cc ATV engine
that i think would be it because i always had problems with the valves i will see what i can do man thanks for the reply and info :)
Where can you buy the gasket set at?
did you find were to get part I need to no my self.
if you cant find timing marks what i do is turn your crank untill piston is at top dead center l ready to induct and mark your fly wheel turn your cam shaft untill it is just about open the inlet valve when you put the chain back on it should be about there give or take a tooth but as the piston drops the inlet should be open
good video tho, after few times watching this vid I finally have a question is your or was your engine 1 down 3 up?
nice video man i love your style your super talented
I have a black washer that says "side out" that I'm pretty sure came from the clutch side but i can't for the life of me figure out where exactly it goes

Hi my bike like the one in this video has the same motor and it wont start someone please help me! :/
Jeez that's put me off re building my 125!!!?
You forgot the timing chain and the gear to drive the valves
Mtb Ridingog
Look from 13:14 approx. He seems to do it arse about face, but the cam chain etc. is in there.
Oops, it's from 8:29; sorry about that.
YOU NEED A TORQUE WRENCH.
Yes
Ron Garvin
do you know what torque a 125 engine case needs?
Brent Reed Its not much. I can't remember off hand but its something like 80 INCH lbs.
What engine Name ? Lifan ?
