This man really knows his stuff. With your videos I have resolved many problems during my builds. I feel like there is no problem that can't be fixed using your videos. I enjoy learning from you and hope to see more videos soon. Thanks man for all the videos and help you provide.

I have no mechanical understanding, but this is one of the most interesting video I've seen, no idea how it came up on my feed, but eyes glued for 40 min. Should be archived as a documentary. Well done, great post.
G'day mate, this is the most informative clip. I have a 110cc Chinese ATV that has had some starting issues for about a year now. I've tried finding some answers to it but nothing has helped. I went hunting and found this video. I then spent around $180 Australian to purchase all the tools you spoke about and I found the issue was compression and the kids can finally ride their buggy again. Thank you very much from our family to yours.
I'm mechanically savy and never took on one of these chinese atvs or quads but watching your videos makes it so simple. Keep up the good work. Oh on a side note I picked up a hobby of fixing junked atvs and selling them for cheap for kids and in the process teach my kids a thing or two. Appreciate your videos. Many blessings.
I appreciate that, because as you know it's not always as simple as it seems on camera! You think the same way I do, getting the kids some educations on small engines and also enjoy the process of bringing them back to life! Thanks for watching!
Liked, saved and subd. How 7 dislike this is beyond explanation. The attention to detail is outstanding and I would not hesitate to have this guy work on my stuff. Brilliant.
Have engine out of frame and in house. Top cover off and cam out. Fair amount of dark oil up top. Did compression test following your tutorial on here. 75. Pumped air in with a car compressor but didn't get air leaking from anywhere. May not have been powerful enough.
I’m from Denmark, owning a Skyteam 125cc…and I must say this is one of the most instructive videos i’ve seen on a tear-down project like this😃💪👌. Great job!
A friend gave me a Meerkat that he couldn't get running. I found it had no compression. Found a bent valve, ordered parts and am getting ready for reassembly. Found that little "funnel seal" laying on bench. I thought I found where it went, but this video verified it for me, along with a lot of other great info. Thanks for the help.
Picked up a couple 110cc Chinese ATVs a few weeks ago, clearing up the garage so I have room to work on them, and stumbled across your channel. Appreciate the content, you've got a new subscriber!
Thank you I own a 125cc coolster jeep that’s having this issue. After watching you I tested the motor and got only 40psi so now I know what to do thanks to you my new friend
Thanks for the video. Bought a 50 cc moped for my son with a bad cylinder head and needed to see the dismantle part. Great tutorial. Greetings from Sweden.
That's defiantly a future goal of mine. Right now between my full time job and being a husband and father of 4 my shop time is limited. As the channel continues to grow hopefully I will be able to shift my schedule to allow more shop time. Thank you for your support!
Bro, I had to put a new head on my vader125 and your video made doing that a whole lot easier . I learned alot from the video. Also I went on and put a bore kit on it and a new race cam while I had it off. Mine as well right. This video made the process a whole lot easier and quicker. Appreciate it 👍🏽👍🏽👍🏽💯💯💯
Love your videos bro... very thorough and easy to follow. More power! Doing a full rebuild of a 9 year old idle 110 CC China made ATC to 154 CC. Just started the job.
As someone who's applied Honda's torque specs to the clone and snapped a couple bolts, I'd say look up the motor model number and see if you can find it's torque specs, because extracting a snapped bolt is a huge pain. Given I looked for hours for torque specs before using the Honda specs, it's still at least worth a little research.
this is EXCELLENT! mine just started spraying some oil, I think out the carb, I need to investigate more, but it seemed like it lost some power, then I noticed the oil!!!
@@PraskaBoysGarage you do great work,I am currently working on a friends ATV,got spark,repaired a ground wire it seemed to struggle turn over,I had fresh gas,checked spark ,ext. What could I be missing? I fully charged battery,checked timing as well ,pulled the stator off to ck for burns on wires etc,now I don't even get the starter,to turn over,what am I missing,getting frustrated
The motor has a chain tensioner. There is a 14mm bolt on the bottom of the engine next to your drain plug. If you remove that bolt there is a spring and plunder behind it. Once removed you can easily get the sprocket and chain on.
2 for 2.... just subbed on a prior video i watched. Long story short i used to turn wrenches on small engines growing up and but never did a full teardown. anyway got my boys some used 4 wheelers. they both run just a bit rough so i wanna tear them down and see what i can do to tune them up. or rather wasnt sure about doing it until i found these videos now im looking forward to actually trying a full teardown on one. Anyway keep up the awesome content and thanks for the help
these engines are wicked. hoping my mate sells me back my 125cc Orion bike thats got low compression. just discovered these engine are made the same throughout with little differences here and there. been doing my homework and think a 140cc would fit nicely . haha.
Man thank you so much!! Straight to the point, thorough vid. I couldn't ask anyone to explain it better lol. Love your content man. Keep up the awesome vids
One of the best videos on rebuild that I’ve ever watched. Totally got me excited to do mine. Wondering 1 thing. On the exhaust port, my assembly has a very thin and malleable piece of metal where the exhaust pipe marries into the assembly. Wondering a) how serviceable it is, b) there’s like a rubberish washer down in there that was coming off in chunks that I don’t see as part of any rebuild kits, c) if this is crucial to good performance to make sure this is right. I can probably get it back to round, but it’s so flimsy that any on and off of the exhaust will just mess it up.
Since I am not looking at it I can't tell you 100% this is it but rather a very strong guess. It is most likely a crushing gasket. It usually comes in the kits as a brass ring. It seals the exhaust to the port. You can buy a replacements for under $5 bucks shipped. Yes this is crucial that way you don't have an exhaust leak.
So detailed so helpful. I'm having trouble determining what next move should be. Low compression and the leak is at intake. Not sure where to go from there
That is one trick table with swiveling engine stand my good sir. Thanks for the details we (I) want. Personally, I appreciate how you cleaned and inspected the old parts versus replacing everything because it came in the kit. One thing I've been taught though is to only use gasket sealant on the outside aka the part you're taking off. Have you ever tried this method? What are your thoughts?
Realy Mr,young. Men,My Bros,& kid enjoy & learn a Lot from your teardown & built videos,thanks to share,se wanto yo see more of your issues & upgrades with minimotos & atv ,Aldo,motorized bikes gas engines thanks,wey suscribe,Joe,Bros & kids thanks.
Thanks man, I haven't done very many How To videos so I struggle with making sure I cover all the details, but if TH-cam and the viewers like them, I'll keep working on them!
Awesome, gonna be tearing into my kayo 150cc minigp this weekend. Spark plug says it's running lean. I richen it up a bit and starts bogging horribly. I left it like that for a track day though and just kept the RPM up so it wouldn't bog. Spark plug STILL saying running lean, so thinking the timing or valve clearance is off.
I wonder if they make a jet kit for that ATV or maybe it would be better to upgrade to a Mikuni Carb, especially if you are taking it to a track. Good luck on solving the problem, and thanks for watching!
Isn’t ignition timing spec 15 degrees BTDC on these things? I’ve noticed a T as well as an F on the flywheel, should cam sprocket be set when “F” on flywheel is visible in the viewport instead of the “T”?
I bought 2 brand new Chinese dirt bikes. Within 5 hours of running, one got a bent intake valve. I replaced it, and within 1 week, the other bike got a bent intake valve which I am now replacing. What would cause this? Valve clearances too tight from the factory?
very nice video, however by the time I buy valve kit, spring compressor and everything else I think id just buy the whole thing for $50 and save myself alot of time, but very good video for someone who has time and patience and more importantly that compression tool
My engine stand is probably the most popular tool I have. I got it off eBay back in 2018, but the seller is hit and miss when he lists them. I am currently working with a guy who owns a CNC machine to start making them myself!
Hello, I teach the Outdoor Powersports program(motorcycle, ATV & snowmobile repair) at Region 10 Technical High School in Brunswick, Maine and our first year students just watched up to the 17 minute mark. We have a few comments - 1st off, as the Instructor, I have 40+ years of experience in the Motorcycle trades and I'm a Certified Honda/Yamaha Factory Trained Technician. I have been teaching for 23 years now and I find youtube can be a great learning tool (not always in a positive way though). We noticed that while performing the leakdown test, you never verified if the piston was at TDC on the compression stroke or at valve overlap! When you remover the cam sprocket cover , I did see that the motor was at valve overlap as the camshaft timing marks were 180 degrees off - OOPPS!! You removed bolts that you said were 8mm but are actually 6mm (with a 1.00 thread pitch). Yes an 8mm wrench fits, but that is not the bolt size. You pried off a cover with a screwdriver (a no-no). You also refereed to the valve adjusting lock nuts as " 9mm bolts". And pretty sure that any engine with daylight coming past the valve seat will not even build up any compression let alone, 70 psi of compression. My guess is the piston ring end gap is beyond specs due to lack of proper air filter maintenance and that explains the massive oily/carbon buildup on the piston crown. We will continue to search the web for more videos that show us how-to(or not), thanks for your time, Bill Ross
Bill, first let me say thank you for watching the video or at least 17 minutes of it. Unlike you, I am no professional and have never received any technical training to work on small engines. However the purpose for my video is to help others who are also in the same boat I am(not a mechanic). I wish we could all take our powersports to shops like the people you are teaching will work at some day, however the cost to repair these knockoff motors professionally is more than the entire replacement cost of the machine. I here your critiques and will look to improve the quality of my videos in the future. With your background and knowledge of powersports I would encourage you to film videos yourself. Please understand you wont get paid for these lessons you spend hours upon hours filming, editing and posting but you will get the enjoyment of teaching us the proper techniques. Thank you for your comment.
