Thank you so sooooo much after 1 week finally started my bike all because of you thank you so much again..god bless you
Happy to help someone!!! And thanks for positive comment
Great video not too long and told me exactly what I wanted to know cheers bud
Very good video. Very helpful and full of info 👌🏻👌🏻👌🏻
Thanks for this video I've just got a gt125rc and it was leaking from the chain tensioner and when I replaced it I didn't sort the tension out and it jump I was lucky as I followed this video for rear timing and now my engine is running.
Also what engine bolts into these for the best performance. Thanks again
Hi thanks for such positive comment so glad to hear someone got some help from video and this channel is all about help people!!! Hmmm about the bolts I am not to sure
Hi i have a small question wats wrong with the engine on gt125r 2009 if there is loads petrol in the oil ?
Be careful people with the time chain tentioners they break and apparently hyosung was doing recall because of them failing apart the reason I am saying it because I am rebuilding bike with cam chain tentioner failure caused the valves to bend and cam shaft snapped in half . The tentioner has got spring that snaps and loses the tention causing the chain to become loose and jumps over on the cam shaft changing its position and than impact of the piston with valves . I Hope this comment might help anyone I will be putting manual cam chain tentioners , the motorcycle has got barely 10k miles on the clock .....
So true I think manual one will be better
Can you do the adjusting with engine still in bike or do you have to pull out
You can do on bike you got lots of access
Thank you so much helped alot
Happy to hear
Great tutorial!
Do you have the valve clearence for gt250r 2016? I need it sir :(
Hello. Mc mechanic her.
Valve clearance:
Intake; 0,10-0,20.
Exhaust; 0,20-0,30.
And pls take note:
When adjusting the valves on the front cylinder, you turn the engine clockwise. When adjusting the rear cylinder, you turn it anti-clockwise. Else you will break your engine if you start it without doing so. Also, when you have adjusted the valves on both cylinders, turn the engine clockwise and make sure it there is no blockage before starting it up. Good luck, hope you get it to run!
Hey bro, I have a same brand motorcycle. I just wanna know where you located so I can bring it to you to fix the problem
In London
is there any diference between rear and front SPROCKETS?
or between intake and exhoust sprockets?
why the sprockets are not available separetly, and you need to buy a whole assy?
tapijas good question!! Front cylinder and rear cylinder they are the same cam and sprocket just marking points will be different if you really need that information I can make a quick video?! Intake and exhaust sprocket are same but to remove tham first is you need to get bearing off! You can get tham separate but not easy to find try hyosung website or get sprocket for different bike just to make sure they will fit there is some in eBay!!if you need any engine parts in Uk I can give you contacts for best prices second hand!? What is the problem with your bike??
@@r91motorswelcome79 my camshaft chain tensioner in front cylinder broke and chain jumped over. Both camshafts seems to be ok, but the sprockets are damaged - the teeth are little bit eaten. It happens suddenly, no symptoms I had like some kind of noise or similar. I also had to change a timing chain and magneto gasket. My bike is 2008 Aquila 250 EFI
Yes affortunet tensioners can make a big problem!first check the piston and valves if they are ok Or you did already? I would you to suggest just to try get second hand or brand new cams with sprockets if you can.. because if you will be able to find just sprockets you need to remove bearings and replace with new ones so x2 sprockets and bearings all x4 that could cost you maybe just a little bit less but more work and bearings can be pain in a**...
now I'm conused. Why should I need a new bearings? The repairing man never mentioned it. Can I just return the old ones? I noticed that ref. number of bearings matches with suzuki psrts. It's probably compatibile because hyosung was making machines under suzuki license. In Croatia there is no hyosung official hyosung service :(
tapijas well if you get them easy off there should be no problem and you don’t have to change tham if you don’t want to..just my self if there is opportunity to change tham I do than I know the parts are new and should go for much longer! And yes suzuki parts should be fine for hyosung same company guy created the engine!
Does this setting will work in hyosung gtr 250 comet
Yes should be very same
Hi mate. I have a gt250r on my TH-cam... Have you heard that noise before? I know its hard to tell from a video
Netherton Motorcycles hi yeah sound not well if you do slow motion recording on your phone so then you can tell sometimes what’s wrong!! First If you can open your cylinder heads only x4 screws and check the crankshaft chain and check if one of them are not loose? To me sounds like is piston one off the cylinders I would give 80% that’s the problem! But do you hear we’re the noise coming from??
hi u know hyosung gt250r 2010 model shim valve mm ? tolerance and mm i know 15 in ex 25 right or ? and hear 8 in 12 ex which is correct?
sallamaçay Hi I am sure I did 250cc before but just can’t remember the correct measurements But we can find out what problem you got with engine noise coming??
sallamaçay if you got one of cylinders making noise you can check clearance on second cylinder if that cylinder is in working condition!! And you will get clearance measure from there if you know what I mean?! Hopefully that will help.. if not than will try something else!!
Will this apply for a Hyosung gd250n?
Benie WITHDAHOOD hi yes same tactic!! Only 250cc chain is double and sprockets bigger but the tactic all same
I set the cams to the same points like u said but my engine is now or just lije before it is still locking
Sorry so is it locked or what’s happened? When you adjust your letters F ad R put something long in to the spark plug hole and make sure when you turn camshaft to adjust letter pistons are on top if you know what I mean!
What happened with engine before you adjust timing
Bro can you make a video for 1 cylinder of Hyonsung 250
What need to do if exhaust shaft not aligned properly
So is it a quality bike. Are the motors good in them I know Suzuki design them. I have a 08 250 gtr it runs great. I like it.
To be honest I probably sold Like nine off this bikes and people like them cos of size and look but about engine quality they somewhere in a middle I find common problems or this bike is fuel problems vacuum and pistons so some cases transmission not the best but also not the worst have to take more attention to bike and service regularly still like the bike and great for the price
@@r91motorswelcome79 thank you for replying. When should I service mine. It had the 600 check. It has 1,200 miles on it.
Hi mate having a Couple problems any help
Hi there can you pls send me pics on the timimg marks on the 250
Hi i was just thinking can i put a 250 piston and cylinders and a 125 GV head on thank you
not to sure but nod bad idea never did my self but could be interesting to know
@@r91motorswelcome79 so it may work so i can fool the police lol
@@craigcoates289 probably not sure do because never did but like a project or knowing something new why not
And what if you lose the correct timing while replacing the tensor? How do you proceed to the correct timing? You just take the chain out of the camshaft sprocket and spin it to its correct position by hand?
New subscriber here! Thank you!!
Hi you got front or rear cylinder?
vcmrco.O 1st use screw in the tensioner to make chain loose than kind lift chain up between cam sprockets and try to spin adjust correctly sprocket were should be marking position 2 first than pull chain tight and place on that sprocket and than do tensioner side adjust sprocket position 3 and place chain on a top but make sure is not loose Than hold your hand on chain and realise tensioner spin engine couple times make sure going smoothly and if needed try to screw more in tensioner! Hopefully will help and also always start with side were is no tensioner if struggling can do some quick video
Have you ever had any problems with starting my was running perfectly now doesn’t wanna start
Check your cdi box. Controls the spark to the coils for the spark plugs. Or possibly carburetor issues.
my bike is having a mettalic sound coming up from front cylinder and and black smoke is coming out ... i checked the timing and the timing is okay ...i don't know what to do now ...can you please tell me what to do ?
Hi what brand is your bike and have many miles bike did ??Could be just a piston ring usually when smokes are coming on piston oil ring is broken or just old if the oil gets to cylinder together with petrol usually give the smoke and metal noise And when you check piston just also check valve on a bottom of the cylinder if there is any Gup should not be
@@r91motorswelcome79 Hyosung GTR 250 changed the pistons to new one
@@proy1895 before you change piston did the bike give you smoke before
@@r91motorswelcome79 yes but I also checked the valves is okay and had doubt on crankshaft and also changed it with new one
@@proy1895 sometimes the sound can com up from oil pump also got video about it not to sure have to think about it very interesting
Im done same like on this video,but why when its get started,loud explosion sound comes out from the exhaust
apat bond wow explosion sound maybe is something to do with your petrol carburettor maybe!! If you put wrong cam chain and parts it would lock the engine and probably damage your pistons and velves!! Is it starts up?
If it's wrongly done, how long will it take for the engine to break a valve.? Mine started and after idling for 10 min, it broke the exhaust valve
The cams are what the chain is attached to on the sprockets.
Hey man I’d appreciate it if you could send me some photos of what you are talking about
Does this have to be timed on compression stroke?
Yes so when piston is right up that the point but if you never done this before just follow steps
@@r91motorswelcome79 thankyou, recently timed the engine thanks to your video! Have to change piston tho as there's no compression
@@ographicshd3467 glad something helped from vid hopefully you fix the problem
Bonjour merci pour tous ces informations que vous les données sur Internet c'est super cool et je voulais savoir si vous vendez un moteur hyosong GT 250 merci d'avance cordialement
I am afraid my friend I don’t understand this language if you need help send me in English Russian or Latvian thank you
hello sir, I just wanted to know if it was possible to buy a 250gt engine and I am in France thank you in advance
@@ozgurdelibas872 yes of course you can buy there is new ones in ebay from USA but shipping charges are very expensive but what I did it’s a cheapest way is to buy some smashed up GV250 and just take engine out you can buy all bike like very bad body or damaged and just take engine out and that cost me just 350£ end rest of the bike use on parts or just scrap it check ebay Facebook marketplace or try to find some auctions we’re you can buy damaged bikes I think that’s the best option and also the cheapest one also you can try to look in COPART auction I am sure you have them in France as well
Hello can i do it to mu hyosoung 125rt ??
Mostafa elbouhi yes you can
Hi, have you done a video of a complete chain change? Many thanks
lee bartlett Hi no didn’t make video but is not to hard to do what you would like to know??
R91MOTORS TWOWHEELS Hi thanks for replying, my bikes making the common tapping noise, I’ve tried doing the cam chain tensioner from your video but no joy, now I’m thinking it could be chain needs replacing.
lee bartlett hmm if some noise coming could be one of the reason do you know we’re the noise coming from? Usually if chain is loose than yes it will make noise but there is 3 thinks makes noise also piston, velves , is it front or rear cylinder?
R91MOTORS TWOWHEELS the noise is definitely coming from the rear cylinder area
lee bartlett to replace chain I got one video we’re I remove clutch from the hyosung I think that will help and you will see we’re is chain and have to remove just look for hyosung clutch removal
Sir I have some issue...my bike is aquila gv250 my front cylinder is not working..i check front head value tapad timing every thing is okay.. injector properly inject fuel and spark plug spark current but cylinder is not working only rear cylinder working...if i remove rear cylinder coil wire then bike goes off...and same as front cylinder bike start and off instantly..so please help me...one thing my bike is gv250 and my bike ecu is gt250r but same engine only body change
Hi have about compression is there compression in cylinder ?
yes...i checked both both cylinder
Hmmm that’s interesting if injectors work properly and you got good blue colour spark and compression in cylinder I am sure it should work but could be some issue with timing chain maybe jump for a teeth or for some reason under compression spark disappear did you did any kind of work before it happened if not have did you suspect the front cylinder don’t work
Hi same problem for me also.... Front cylinder is not working ...what will be reason n how to rectify....
@@rameshbmaw3834 guys go for ride if you can or run bike for good time and check if the cylinder you think not working is warm because rear cylinder will be always warmer then front if is completely cold then do this steps...first check if there is constant spark in blue colour second make sure there is fuel going to cylinder have to be same in both cylinders 3rd compression in cylinder if this all is fine then I think you got problem with timing chain not a big deal but still a bit work to do just let me know have you do will try to help more
I'm. sltan Raja ,,,RT 125 T,XL timing theke Bain boss .. Bangladesh mymensingh
What is the Hyosung 250gtr engine oil capacity ??
Maximum is 1.5L if you change oil filter first put 1.1L and run for some time check your level and ad more if you need don’t put straight 1.5L do slowly to get to right level because if you put to much you can damage gaskets and engine that will cost money
Thanks for your information.
@@ktp2223 happy to help
How do you adjust if off?
Brendan Driscoll you mean chain with tensioner?
How many teeth the timing chain is?
I am not to sure never checked! Can I ask you why you want to know ??
Can the wrong timing cause bike not to start
Guy Martin Kenya yes it can happen if you put them another way around spins the engine but not starting also you have to be careful it could damage engine if you put them wrong you got hyosung or another brand?
My cam chain is loose . What cloud be the problem
Tensioner mate have to be replaced there is two types one adjust manually and one is same like yours is up to you which one you want I suggest manual one but you have to be careful to make sure you don’t do to tight the chain if you know what I mean
How do you tighten the chain if it is loose?
Ali Alcala Hi if your tensioner is still in working condition than remove 10mm bolt from tensioner and try to push more in sometimes they not going in till the end.. but if will not work there is another way to do try to spin slowly camshaft and as soon chain is tight release tensioner but you have to make sure when you move camshaft you hold the chain tight to cam sprockets so chain is not moving again always just put marking points just in case .. I will put video soon about that’s
Ali Alcala also try to turn little scruwe in tensioner anti-clockwise that may go out feather as well
Thank you I’ll try that, could you possibly make a quick video on where each line goes. There are videos out there but they skip a lot of lines and I’m trying to put my bike back together but I don’t know exactly what line goes where
Ali Alcala you mean carburettor lines?? Or timing chain?? What you struggling now? Yes I can make video !!
R91MOTORS TWOWHEELS when you take the gas tank and air filter off. All those exposed lines that run from the carb, gas tank , air filter and where do they connect to the fuel pump and the vacuum pump I think that’s what it is like just ever fuel and vaccum line from point A to B. Thank you!
So what if your bike is ticking like mine, what if you have to change the position please
If is ticking could be your tensioner!! What position you mean timing position if timing would be wrong you could not start a bike or cylinder would be stuck for wrong alignment
@@r91motorswelcome79 I went on a long ride upto Wales, seemed the hotter the engine the louder the ticking, also the throttle is very sluggish until its passed certain amount of revs
@@r91motorswelcome79 sounds very spluttery if that makes any sence especially going slow, throttle is unresponsive a til passed 3000 revs then kicks in to life?
@@user-http55588 what year is it ? You got carbs or injectors
@@r91motorswelcome79 66 plate it's been like this straight from the shop and slowly got worse, I changed the exhaust to sports exhaust thinking it might be to much compression so the engine having to much feed back but now I'm lost
It did not work on my carburetor hyosung gt250r
Bro my rear cylinder not firing..any solution??
First make sure there is fuel going to cylinder is it bike starts even badly ?? Because sometimes there is problem with fuel not going properly to cylinder and also spark ?!! If all good check your magneto rotor there is marks F and R letter f for front cylinder and r for rear make sure they much up!! Just tell me full story what you did with bike and what’s happened and also brand
That would help more
Model is Hyosung 650..once engine gets heated only one cylinder is working.
@@madhavkishan7561 let me gues is it a rear one doesn’t work??
@@r91motorswelcome79 yes u are right
I done this now my intake is my exhaust lol
Adjusting tensioner
You. Want to know have ??
Crankshaft not camshaft friend
You showed no adjusting
Well steps are pretty easy just put your adjustment points on correct position you can see on video put your chain on sprockets and do up your tensioner!! Thanks for comment
