Cam timing problem

Aa

[@MrJulianneave]

The timing chain of this bike is stretched and needs to be replaced. To stop the crank turning back by itself you can either take the spark plug out, or putting it in gear will also help. Also, fuck everyone who is being hard on this kid for working on his own bike. You have to start learning somewhere

[@joajaimemarti4556]

julian neave yea your right you have to start learning somewhere i started on motor bikes this sumer with my dad and im only 14 years old funy enough me and my dad have alredy fixed a motor bike that was jamed at 80km an hour bicause someone (my dad) forgot to ad the oil lol but now its completely back on the road and now im working on my second bike wich by the way my dad will let me ride on ;)

[@pjdeltoro3592]

Joajaime Marti ok.....

[@josepeixoto3384]

EXACTLY!!! but... i have one like this(Keeway ARN 125 4t,with 39000 kms) exactly 1/2 tooth off,due to a very stretched timing chain,but the bike runs well; just,the compression is 12 bar,instead of the factory 15 bar,but it runs almost fine,still does 91 km/hr top speed; within less than a year,i will have to put a new chain in. i'm a mechanic;

[@remanspecialist]

If the flywheel wants to move like that you are on tdc of the exhaust stroke not the comperssion stroke, turn the flywheel another full turn until you get to the T again. Little late but might help somebody else.

[@pittymechanic6176]

lol its 2021 and i hav that problem and u just helped me alot thanks

[@ToxicLion]

Same

[@snoobabs1]

Same 😂 Except mine deflects on inlet AND exhaust 🤷🏼‍♂️🤙🏻

[@reecetaylor9518]

You helped me more than this video did

[@liamcopus2999]

Hoping you have just solved my issue 🙏🙏

[@greasemonkeypol]

it is chinese yes but this happens to hondas too in this engine the cam sprocket is 180 degrees off which is no big deal actually now if you put it wright it is going to be again half a tooth off this is because the sprocket in the crankshaft has not a guide and it causes this. anyways stop judging this kid hes trying to learn just like you years before and yes kid your bike is fine leave it as it is

[@jmsbrynt]

how do you adjust the timing of the cylinder head when it’s detached from the rest of the engine? i can’t slide it back on without moving that gear which that the timing chain was on?

[@anthonymacaluso1488]

It's just off one tooth, take the three screws out and pull the gear off the cam, and scoot the chain over the cam sprocket and put it back on. It will run one tooth off either way, one will give more bottom to mid range and the opposite way will lose some bottom end torque but will rev higher. Kinda a preference thing and how you ride or the track you ride on. Good luck buddy

[@zb7338]

You can move the cam sprocket in the head while lifting the chain off just slightly enough to get the sprocket in the right position and bam you'll be fine. Might want to check your valves too while your at it

[@NCmtnDweller]

Yes sir - Thier is several indications another human has been in motor etc scuff marks on alum surfaces so I hope sprocket is simply off a few teeth & thank u for your help I will post results this evening.

[@dylaneagleton3090]

You will need to adjust the flywheel 180 degrees because it is on the intake stroke not the combustion stroke and the springyness is the valve spring opening the intake valve *thats what happened to me when I put it back together*

[@niceone3091]

Hello, i think i need to do what you are saying. Could you please explain it more for me. Could we like get in a chat plz help.

[@aukanmeister]

Fun to read the comments. So many people are quite sure of what is "wrong" here. 180 degrees off, jumped a tooth and I don't know what.. This is why we need to teach our children that the internet is sometimes not correct.

[@1vafalcon]

Thanks for the video..Big help

[@crockediledundee]

your timing is 100 procent ok , start it up , and it will run excelent

[@mikebrunk6884]

Wait really? I'm having the same issue

[@bistakos1]

in this situation you try jumping a teeh and a second move is adjust the sliders to keep the chain more stretched or loose

[@georgege-gewebber7814]

I got exact same bike.... wedge a philps screwdriver through were it matches T mark were it won't spin so easily... take the 3bolts out.. then the 4 nuts off that hold head in ...slide first part outjust enough can slide sproket out.. move it up/ down a tooth or 2 were matches up .slide it back down .. ........ once it's matched up .. take the screwdriver you had wedgded in it and can turn the kick start till bolt holes match up... put it back together... then wyen turn it to the t it will all match up

[@stock92csm]

stretched chain is correct... the method used to fix this is called "degreeing" the cam and that's where you get an adjustable cam gear (or just slot the factory one so u can adjust it) and set it to be perfect.

[@anthonymacaluso1488]

I would say that cam is shot, and it's moving.he could degree the cam but it will move again lol

[@fotisterz7068]

i've seen this happening before..the rear sprocket on the crankshaft is a press fit and it needs to be extracted and pressed back to the right position which should be the woodruff notch on the left side of the crankshaft between two teeth of the crank sprocket..

[@elisalazar3097]

Hold the fly wheel so it doesn’t move adjust the chain and check clearance on the valves

[@dash50]

try to change the tooth of gear one back ;)

[@Tristan102100]

if it runs like it's off the showroom floor it is perfectley fine the notch is suposed to be a little below mark but don't ask me why

[@mikebrunk6884]

It's supposed to be under the mark im having the same issue and kinda lost lol

[@ProfileP246]

Take plug out Remove cam pulley bolts Line flywheel with mark move cam pulley teeth around on chain until it lines up with mark Tighten everything up and do couple turns with spanner to make sure all stays aligned 👍

[@EZTM4NICKILLZ]

timing out by 180 m8 spin your flywheel around to the t agine and u see that it will stay in the t and the dot will be on the other side to where it shud be i just set my timing up and notice i did the same thing

[@niceone3091]

Hello, i think i need to do what you are saying. Could you please explain it more for me. Could we like get in a chat plz help.

Im having the same issue

[@dripdasmoke4890]

uK BLaZe uK i need some more detail for this

[@TJ-hd2jg]

Same

[@dripdasmoke4890]

T J I found out there isn’t anything wrong with it i think And if u think there is something wrong then make sure ur exhaust valves are adjusted to spec

[@khosikhosi8932]

your bikes timing is spoton the way is i corrected tht and had problems had to set it back to tht off position nd it wrks fine,if it aint broke......

[@brettoliver3691]

Its the stator magnets, thats causing the engine to turn, the cam may be one tooth out but t looks a little to close for that, its most likey that it a cheap chinese motor and their maching isnt so good..

[@mrmechanic1385]

Do you timing again try to get it lined perfect and its normal for the flywheel to move when its on top dead center because of the magnet

[@randy1ization]

I had the same problem, the teeth on the can sprocket in the head are worn. when u compare a new one to the old one, you will see it clearly.

[@EZTM4NICKILLZ]

if it still moves them your valve need adjusting coz it pushing the piston down when thay shud be closed

[@curtanbev1]

did you sort this problem out as im having the same problem if so can u let me know how u did it thanks

[@johndoherty8681]

just seen this ,thumbs up to all that gave good answers on this and the kid is asking for some help here not to be sniffed at and basically not told to fuck off he as got some guts asking as seen a many of want to fixers with there bike and just ended up scraping it in the end as they do not know what the fuck there doing so thumbs up to the kid as well ,,if you took the spark out you will get less suck on the fly well and even if he had taken the fly wheel off removed the stater plate the would not have been any suck or pull back and he can just sit the fly wheel on turn it and get the timing right this way as to look at it ,it was only out by one tooth any way ,and just replaced at the parts and it would have run fine ,so to all you hard to make happy people that give answers that he did not want to here just not bother

[@jojusoh1421]

Good video

[@jimmy21150]

right kid firstly line up the t with the notch then undo all three 9 mm bolts on the sproket then take the chain off the sproket make sure the fly wheel is still lined up and line up the sprocket to the notch on the cylinder head then keep turning the engine over with the sproket on and the chain on with everything lined up untill you find that the three holes on the sprocket have lined up with the threaded holes in the cam then tighten the bolts back into the cam with the sproket still.. finish

[@niceone3091]

Hello, can you please help me with this timing, when i readjust the cam sproket do i need to just insert the bolts and thats it or do i need to spin the cam at some direction and then line up the bolts becouse in your case im just moving the cam sproket and that shouldnt do anything

[@smallbikes]

Stick a screw driver down spark plug hole turn engine over until piston is up top, you will get a proper top dead centre and make a new notch on side casing I'm sure you will find they stamped it wrong from new pretty much every pitbike engine iv owned are top dead. Wrong from factory lol

[@OliverMatibag-df1wq]

Timing cam sprocket has three bolts . You aligned the thread hole of the cam shaft to the cam sprocket using an ice pick

[@rnrrepair43]

Take the timing chain off and line it up properly p.s. the timing marks on them chinese motors dont line up completely anyway

[@justinvnickoftime8068]

Timing chains don't stretch ?? Wonder why companies waste their time selling pre-stretched chains as an option for then ?? I am glad Skoda sold their 1.3L replacement timing chain pre stretched or none of the cars would have run ....... MMMM , i wonder why spring loaded tensioner's are fitted for ? Surely this cannot simply be for roller wear ..... Firstly look under the engine for a timing chain adjuster spring housing nut just off center of the flywheel, if yours has it then remove it and the spring .Shove a long screwdriver into the plunger hole as hard as you can , and note the sprocket position to see if the tensioner was simply stuck ( the timing marks now line up ) or if the chain / sprockets are worn ( No difference to the mark positions ) . If the timing is still out - You will need to strip the head and barrel off to inspect the timing sprocket and the guide sprocket in the barrel , then if they are not worn you have to remove the flywheel and back plate with the electrics on to gain access to the tensioner and bottom sprocket , if they are ok then you will need to replace the chain , your better off replacing the chain along with the bottom and top sprockets , the bottom one will need heating with a blow lamp to aid in it's removal as they are hot pressed onto the shaft in the factory ( sweated on ) .Sounds daunting but easy really . If you find the chain is just stretched , make a video of it laid along side a new one with the first chain pins in line to enlighten the idiots of the fact that chain plates do stretch . Though after 4 years i would have hoped you had it done by now anyway ....... And before you idiots start ripping me apart , i have 40 years in the engineering / motor trade , type in judds porsche to see a 630BHP monster ive worked on getting caught on police camera . Yes i can work on anything from a Mobylette to a super car , and make them better.......

[@twizzlestickx7]

its on compression stroke thats why its doing that numptys lol

[@wibisk7175]

timing chain is damage. that is honda c100. simple desain engine.but very reliable.

[@greasemonkeypol]

hes talkin about the other chain...

[@motorcyclemechanic.]

Loosen the three bolts on the cam sprocket move the chain around one tooth put it back on your good, if it still doesn't start checking compression, probably a valve

[@elisalazar3097]

vincent padula check for spark at spark plug

[@ChrisGalvinLimerick]

Has anyone said what model of bike this is, I am looking for video to set cam timing on honda rebel year 2000,, 125cc anyone help me thanks

[@daDfarSpanTaistheKin]

remove the spark plug and it wont spring back.. it springs back because its at TDC of compressio and the compressed air is pushing the piston back .. so the flywheel springs back ... time with spark plug removed .. first bring it to TDC then remove the spark plug then re adjust the flywheel..

[@Impossibilty232]

it is sposed to be like that man the notch will be slightly off

[@justingreaves6769]

Valve gaps or carb mixture screw

[@zesthraxGaming]

+Justin Greaves what is the carb mixture screw

[@justingreaves6769]

+Typical Vaper a screw on the side of your carberator that adjusts the air and fuel mixture. Looki it up. Also check your valve gaps are good you should be right then

[@zesthraxGaming]

+Justin Greaves lol I figured out that my intake valve is fucked lol.its bent so it's not seating to where it makes a seal.this is resulting in compression loss which is also why my engine is back firing out of my carburator

[@bryanwillmore593]

What make is it

[@randy1ization]

I gaurantee you if you put a new cam gear on, and dont put a new cam chain, it will line up fine. Ive had this same issue before. you are 1/2 tooth off because the teeth on the cam gear are worn. they tend to wear fast on these engines, due to a poor oil system to the gear. theres just a tiny hole that lets oil go to the gear. I am a master motorcycle mechanic on the ct70 and 50 motors., I know everything abt them.
