- A "how to" video to show you how to change the stator plate on a pit-bike if the pitbike has no spark
Usually if the chain breaks or comes off it goes around the front Sprocket and damages the casing and the stator. This is a common problem on these bikes.
It's important to look after your chain or it costs more in the long run

Thanks so much - your video described the job perfectly and was invaluable in changing the strator plate!!
Thank you very much 👍🏼
This video is actually perfect 10/10 the accent puts it over the top too
Thank you very much 😎
Your content is bang on so helpful and comes up in seaches right away, really appreciate it thanks mate
Thank you very much
I have the same stator but when we got this thing used I don’t remember seeing the pick up. I have 4 wires coming from the stator, black is ground I suppose brown and a grey coming from left copper coil and and white from the right. Any ideal what I may be working with?
Hi Rich
TBH i can't remember off the top of my head and i don't have one around atm to check for you sorry
The wires normally match up with the colours on the wiring loom but i would have to look at it to work it out if they don't. normally i plug in the ones that i know then just work out whats left.
the ones from the charging coil though can go either way around.
@@motorcyclefixer thanks
Awesome mate... I was wondering if my stator was stuck and did not want to force it but you have confirmed my suspicion that the O ring is holding it and you just need a little muscle / leverage to get it out. Thanks for the video it was a big help.
Glad I could help
@@motorcyclefixer that worked for me too...
Thank you so much for this video! I thought I needed to buy a whole new motor after my chain came loose and broke the small piece, just like the other one you showed.
Glad I could help
Bro you are a great teacher, if you could find the time to do a vid on motorbike electrical system, stator, coils, rectifier etc it would be awesome as there is hardly any decent ones on youtube.
I have a question! If both marks line up for the timing , can it still be out if someone hasn’t put it together properly?
Not if the woodruff key is in place on the crank and everything lines up
You can check the mark is correct on the flywheel by checking the piston is at TDC with an allen key down the plughole
Dang it man, I pressure washed my son's 110cc pit bike and now I have very little to no spark. Right now there's no spark, but every once in a while itll start, but won't run for long. It has a brand new carb, so the carb isn't the issue. I just don't know much about the ignition system on a small engine. Basically, I don't know how to diagnose the lack of spark. His bike doesn't have a stator cover, but that's never been an issue before. I have pressure washed it before, but I've never had an issue with it not having spark before.
you may have water in one of the connections and it's earthing the spark ???
Also try disconnecting the black and white wire coming from the cdi as this is the cut-out wire if it's earthed
I did the same thing i pressure washed my dirt bike
My stator’s old and the bolts are completely rounded off. How would you recommend i get them out with minimal and basic tools?
Use a centre punch and a hammer and tap them around. 👍🏼
@@motorcyclefixer WOW this is a first for me haha, thanks for the knowledge!
i never really knew about the stator plate until it was almost too late i thought i would have needed a new engine thinking the plate was part of the left side of the engine found a new one didnt know this was as common as its been said to be
the stator plate on my 110cc pitbike only has one coil pack instead of two coils on his pitbike statorplate.is it unusual to have one coil pack?.there is a space for another coil pack with screws on it so if you want to add another coilpack. dosnt look like it broke off .the 2 screws are still on the plate .should u have to give the flywheel a wack with a club hammer or should it push on easy because on my 125cc pitbike i wacked the flywheel few time with a club hammer not too hard so not to damage anything. the flywheel didnt push on much and the notch thing on the flywheel is still 3 quarters off in line of the pickup point on the stator plate even after i put 2 washers behind the 2 screws on the pickup point so that the magnet on the pickup point is pushed outwards a bit more.
The stator plate with two coils is for the pitbike with a battery and lights etc. You shouldn't pack out the pick up
There is a set distance between the pickup and the lug . 0.2mm
Can you tell me what is on the outside of the flywheel that triggers the trigger coil? Is it a magnet, or something else? ( I'm using the trigger and cdi on a different project) THANKS
on the outside of the flywheel is a steel square that triggers the pulse generator as it passes.
Inside the pulse generator there is a magnet that is wrapped in fine wire
when ferrous metal passes closely by the pickup it generates a pulse that tells the cdi when to spark.
If using the trigger and cdi on something else you need to make sure of the timing of the pulse in relation to the crank position to ensure it fires correctly
Thanks for the info. I assume that the magnetic field from the magnets inside the flywheel also have an effect on the sensor?
@@doctorvox they generate ac current when they pass the windings on the coil on the inside
Got a question, think my stater is fine but the wire just above the sprocket for the chain has broken aswell as part of the piece I can’t find anything on what it is or what it does any help would be appreciated
That's just for the neutral switch which normally isn't used.
Is it green and red
If it is it doesn't need to be connected
@@motorcyclefixer thanks a lot mate that makes a lot more sense
What mm is the flywheel puller? I’ve ordered the wrong one 3x now. All too big…
Hi
Sorry I'm not able to measure it at the moment
I'll do it when i can but it may not be until next week
Hi
Sorry but i would have to take the side cover off to check and the engine is up for sale at the moment so i don't want to take it off.
I hope you have success with it though
Where could I find that same stator as a kit I found the stator with a different plate but I can’t wire it correctly
I have had them in the past where i've had to cut off the connector block and use bullet connectors on the wires.
just match up the colours on the wires and connect them together then
What is the small circle thing with 5 magnets and 4 cords just up and right of stator , i bought a bike but the cords were cut . Is that an electric start ?
It's a gear indicator switch.
If you have a display on your bike that tells you which gear your in then this is what controls it.
I had a question if ur stator plate goes out do u just. Aye to change that or all the wiring as well
Just the stator
My stator cover was loose for a bit and i had no idea. It has sand and grit inside it. I cleaned the cover and blew out as much as i could. Will anything get into my engine or is the stator seperate from the oil basically wondering if the dirt will get past the stator plate and into crank/bearing. I only cleaned what i could get to without removing stator.
It is separate from the internals
@@motorcyclefixer thank you i was freaking out after mudding with a freind! subscribed and liked
@@readylucas thank you
Can you leave a link to were you bought it i dont have the orings or seals for the bolt that go into the stator plate the ones you said not to lose or they will leak
I was a dealer for stomp pitbikes.
Go to their website and find your nearest dealer.
The website used to be pitbikedirect. Com
The stator plates come in a box with the screws and orings included
What size is the puller
I believe it's a 27x1 but i'm not 100% sure now as i can't check. Sorry
Hey mate I’ve got a 250cc Chinese bike and I can’t seem to take the stator plate cover off I’ve taken all the bolts out not sure what else to do, should I tap it with a rubber mallet till it comes loose or?
Tap it with a rubber mallet if it still doesn't come loose you have missed a bolt. Is it the type where the gear change comes through the casing
@@motorcyclefixer I got it off stator seemed very nice and clean had oil around it must be one of those bikes that it doesn’t matter if it has oil around it
Hey Motorcycle fixer i have a problem when i changed the stator plate with the new o-ring.I've put that stator in with the o-ring not pinched.And i have a oil leak around the bottom of the plate.Any tips?
There is a small oring behind each screw and the large one around the outside of the stator plate
If both orings are in place behind the screws then the outer oring could be damaged. If all of this is OK then it could be that the casing has a nick or crack in it
@@motorcyclefixer thanks for the advise :)
@@motorcyclefixer But i do remember putting those little o-rings in the screw holes in my opinion i think its the crank shaft rubber seal, i have used metal epoxy to fill the lower oil leak gap and there are now no leaks.But when i also checked the engine and the stator hausing there were no cracks or markings.
It could be the oil seal around the crankshaft if everything else is ok
@@motorcyclefixerYes everything else is ok i'l change the rubber crank seal.And again thanks for suggestions👌
Another helpful video. Thank you.
Thank you 😊
Brooo my flywheel was rusted out I had another engine so tried to put that engines flywheel and stator on mine but the lil pin to aim you flywheel like the crankshaft lil pin it broke off so now the flywheel is on but the crankshaft is moving but the flywheel isn’t help me out.
The "pin" on the crank is called a woodruff key . You can replace them
Measure the width of the slot on the crank and buy the right size to fit it.
Sometimes you have to file down the key to have it fit perfectly but they may sell the exact size on ebay
@@motorcyclefixer thanks I thought I was going to have to replace the whole crankshaft lmao
@@motorcyclefixer you got a sub
Can you do a video on the spring with chain tensioner for cam
What’s the orther wire for that’s attached to the stator coil N goes in another spot top right just above the front cog
It's for a neutral detector.
It's not used on most pitbikes
do yo have a video on adjust the timing chain on this engine?
what did you clean with
If that case is broke on the inside would you have to get a new one or will it still work???
It's best to get a new one.
All the water, mud and stones will be thrown in there by the chain
@@motorcyclefixer what's another way to get the pulley off if u don't have an impact gun???
@@motorcyclefixer thank you very much for the information. Really helpful
Can anyone help me? the 2 screws holding my stator plate in wont come out even with in impact driver they are starting to strip
You might have to get a centre punch and tap them around. I've had to do it before if the cross rounds off.
Motorcycle fixer ok thx
would oil leak out once you remove the stator? is it best to drain the oil first?
You can drain the oil or you can lie the bike on its side
How big of a gap do you need mate from trigger to flywheel
It should be around 0.2 mm
What oil do I use in a 125 pitbike?? PS I’ve subscribed 💪🏻
Thank you for subscribing 👍🏼👍🏼
10w40 motorcycle oil we always use
Great video man thought me a lot keep up the good work how do you put the motor in time would thank you for your help .
thank you i'm glad you liked it.
I'm sorry i don't understand the question i'm afraid
How do you set the timing on the motor with the timing marks thank you.
@@sandraworkman2946 take a look at my other videos
There are a couple of videos that cover timing
Hi mate I’ve got this exact bike and exact problem where can I buy a new stator plate from? Awesome video thanks
Thank you
Glad to help
If you're in the uk, go to pitbikedirect.com and look for your nearest dealer or they have them on the bay
@@motorcyclefixer will it state what bike they fix? Thanks
@@motorcyclefixer or do I just get one that looks the same haha
@@maxmarshall484 tbh if I remember correctly they are all the same for these engines just one or 2 coils so one that looks right should be right 😂😂😂
As long as its for the correct cc.
The bigger 140-160 6 coils
How has dirt and my fly wheel rusted ?
There's probably a hole in the back of your side casing in front of the rear sprocket
i have the same engine and wants to replace the stator. is it possible to remove just the stator without removing the backplate
Technically it is possible but there's no point really as the new ones come complete
@@motorcyclefixer
i understand. mind if i ask a few more questions about the stator?
@@feero9680 ok
@@motorcyclefixer
my bike wont recharge the battery.
theres 6 wires coming out of the stator and they are coloured differently. how do i know which wire is for charging, spark and ground.
you can follow where they come from usually
The ones that come from the coil in the middle are the charging wires
there's usually one green/ red going to the neutral switch which is normally not used
green is usually ground (usually riveted to the back plate )
and there'll be one wire going to the black box that is your spark timing pick-up
Thanks. Iv got a leak. Its a new engine but i have to buy the flywheel removal tool to find it
Try the shifter o ring... maybe that’s the problem
Thanks so much your patience helped me
LOL
Glad I could help!
Thank you for watching
i havnt looked at my bike yet but im sure that this is what happened, chain came off and bike died and i heard some rattling which all adds up to your explanation
yeah i took it apart and you were 100% right about what happened lol funny how hard your video is to find on the subject but i am glad i stumbled across
I'm glad it helped
@@motorcyclefixer thanks for taking the time to post helpful videos for noobs like me
What is the pick up gap
The wee black box is snaped off in mine what do i do
Hi
You need to change the stator plate I'm afraid
M
Where does the little black box goes to it’s just hanging on mines
If it's hanging its broken off
You need to replace the whole stator plate
I was riding my tao tao 110 cc and the chain fell off now it dont start
check the stator plate as in the video
My stator plate is stuck after removing the two bolts, it will spin
side to side with a hammer about 1/4'' but doesn't seem to
want to be removed.
It will come out
Just be careful not to damage anything else
@@motorcyclefixer Thanks, I got it out.
The new stator has a second, short
harness, with some kind of sensor,
any idea what it is , I don't want to drill
a new hole in the case, and can't leave it inside ..
@@bikersoncall is it a green and red wire
If it is it's just the neutral sensor which you won't need
If I turn the bold the wheel is thurning to
What do I do?
The flywheel ??
you need to stop it turning
i use an impact gun as i find it easier
What’s the tool called you use to get the fly wheel off with
It's a flywheel puller 👍🏼
@@motorcyclefixerwhat size?
@Vlxnetrill I believe its m27 x 1
How do i get my flywheel to stay still while tryn to loosin the nut
Use a torque gun and hold it with your hand
Or you can make a tool. You can use a large circlip pliers if you have one that fits
Thank you that was really helpful
Were do I buy that torque gun?
There are lots of different ones available
I bought that one from amazon
What size flywheel pull would I need for my Apollo (chinese) 125cc dirt bike?
i thought 27mm but im not sure
Do you have to worry about timing?
No
Not if you only change the stator
There is no adjustment on these pitbike stators as they are centered by the countersunk screws.
@@motorcyclefixer but you've taken the flywheel off? Would I need go put it back on the exact same way it came off?
Yeah it's on a woodruff key
DOES ANYONE, ANYONE, Know, what is the size nut that you just screwed off the center of the magneto to remove it from the middle? Thanks
I'll measure it for you tomorrow if I get chance 👍🏼
@@motorcyclefixer Thanks a bunch, One search I have noted so far is, ( M10 1.25 14mm Flywheel locking Flange hex nut ) lol, Wow, so many new words I get to add to my vocabulary.
Fantastic video
Thank you 😊
Stomp is a Chinese pit bike too. There are good products that come from China, they are not all bad.
Very true
The stomp pitbikes are made in China but the guys at stomp have had an input into some of the design changes 👍🏼
You can also get all the parts for them which is a bonus
Good video mate 👍👍
Thank you 👍🏼
I can't get the washer out
Hi sorry for the late reply
It sounds as if the washer has crushed around the thread of the crankshaft.
I would try pulling the flywheel off with the puller with it still in there. gently to start though
very useful cheers
Thank you 👍🏼
Those need to be supppper tight so oil dnt leak
Beautiful Scottish accent 😊
😂
@@motorcyclefixer oops Irish? My bad 😂
@@Armageddon-qo4wy 😂😂
@@motorcyclefixer 😂😂
Looks like your sprocket is about to strip out
This is just an old engine i was using for the video
Haha same thing that happened with mine lol
It's really common 👍🏼
This video helped me a lot. Thanks!
No problem
I'm glad to help 👍🏼
