Glad I was able to help!
Thts awesome. I'm so scared of wiring
BJ is a great guy and loves to help people out. We need more people like him around to save the masses of people from pulling out all of their hair lol
@@maximus759 very tru
@@maximus759 Thanks dude! It's comments like these that really keep me motivated to keep making more content!
One of the clearest and most detailed videos on the internet. Great camera quality and expertise on small engines thank you for sharing.
Thank you so much for the positive comment! I really appreciate that!
3 years later I'm still revisiting your video for guidance. I've done about 8 rebuilds and owning 3 atv$ this knowledge is very Valuable $uper value.
I haven't even watched this yet, and I know I'm going to love it and learn lots!
Let me know what you think after!
@@PraskaBoysGarage It was really cool to watch!
One of the clearest, best filmed tutorials I've ever seen. Thank you!
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.
You bet! Glad to have helped!
This is probably one of the best videos to learn this stuff by. Valves seem hard at first glance. You made it a breeze dude thank you
I want to thank you for answering my questions and also for providing a step by step guide to help me get my kids atv up and running again. It turns out that a piece of metal from somewhere got lodged in the valves not allowing them to close. By watching your videos I was confident enough to make the repairs myself. Thanks again!
Hey that's great to hear! Glad I was able to help!
I wanna thank you again....you saved me money and lots of time
You bet man! That's my goal with this channel, help get others up and riding again!
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.
Much appreciated! Thanks George!
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!
Thanks bro for the solid and straightforward tutorial on this. Saved me alot of money and time. I am not a small engine or mechanic by any means but i have invested in tools to make the job easy. Thanks a million
Great info man, been watching a few videos taking this engine apart trying to get myself familiar with the parts and the process before I start it myself. I really like to understand the 'why' behind what is being done and you've given excellent answers every step of the way.
Also, thanks for editing the timelapsed parts. In some of the videos I've watched the past couple days, someone will be like "OK so now we are just gonna undo these bolts here..." *5min later* "OK and now we can remove these bolts under here..."
Thank you for taking the time to leave this comment! I was just having this exact conversation with a friend about the channel. Everyone does it a little different, and my style is how I personally would want to watch. Glad to hear you feel the same way I do!
😳😮🤔🤣
As always great video. Thanks for being so thorough with everything. Just redone the valves on the raptor 50. Have learned more watching your videos than any others so far. Now to tackle some Chinese 125s I have laying around. I have fixed probably 4 or 5 from junkyard just from watching your videos. 2 was as simple as checking for spark and figuring out why it wasn't firing. Keep posting cause we are watching.
Great to hear that Gene! Always happy to help! Good luck on your future projects, and we have more content coming soon!
Any recommendations on valve clearances for 120cc pit bike please?
What a great tutorial! I have complete confidence tearing into my newly acquired basket cases now, Thank you very much!
This video was very helpful, taught me everything I needed to know to get my stomp 125 superstomp running again !! ❤️
One of the best videos I have watched in my entire life!
I don't know about that, but I am glad you enjoyed it! Thanks!
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!
As a 30 yr. Mechanic who has worked on these many times .... I am a perfectionist and overkill everything to get it right the first go out , and you nailed it !! Huuugggeee Klondike Bar for you !! 😎👍
Thank you very much!
This was a great informative and detailed video! The best part is that I didn’t fall asleep watching it! Thank you so much for this! 😎🤘
literally have been searching for a vid like this to help me , your the goat Praska
Lol, no goat here...just a guy with a hobby looking to help others! Thanks for watching!
Great videos you make, gonna try learning my 13 old son about motors, when we go buy a broken china dirt bike for him.
That's awesome! Good luck on the project and hit me up if you have any questions!
This video saved me!
Before this video I new nothing, today I got to hear this ATV running! I. So ecstatic
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.
Love to hear that! I am very happy I was able to help getting your kids riding again!!! Thanks for watching!
Great content as always BJ! Keep it coming!
Appreciate it! Thank you!
I’m hooked. Thanks man these are great. Can’t believe ima say this but I can’t wait to tear down my 50cc now. 😂
That's awesome man! Good luck on your project. Let me know if you have any questions!
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!
Hey that's awesome! Glad you found us and good luck on your projects!
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.
Wow, thank you for the positive comment! Glad you found the video and enjoyed it!
Im sitting here watching this and im fighting in my head “a top end kit is $80 and 3 days of painful confusing work but a new motor is only $300 and only 3 hours of my time 😭😂😂
It's a tough decision for sure! I'm all about saving the money but If you don't want to mess with it you can save the headache for sure for a little extra expense.
Get paid 100 bucks and hour? Good for you man
But guys its soooo funny to work on your motorcycle. And when it works there is no better feeling
Where do you order a motor that cheap ?
@@WokeEarthno the engine cost $300
Where did you get that engine stand? Thanks for any advice
Hi Bj , I must say it’s so awesome to finally find a how to video for working on my 110cc pagsta mini bike. Thanks for breaking down everything so I can understand it completely.
I went right down to the piston. My son’s friend over did it and dropped a valve. It took me two hours to rebuild the top end from a spare motor i had lying around. Never once did I read a manual or come on here for help lol I’m just hear for valve specs 😅
You have some awesome videos with lots of helpful knowledge. If I could ask would you mind doing a video on how to rebuild the bottom end (the inside of the case) by chance?
Yes, absolutely! That has been requested and I plan to do one after I get back in the shop. Unfortunately I had to have back surgery in February and have been sidelined for awhile. In the mean time I have been doing a lot of researching and also buying parts for upcoming projects! Hoping to be back in the shop soon!
Thanks that would be great. I find your videos to be very helpful & has help out a ton. Wishing you a speedy recovery. Take care & thanks again.
Great content but wish u could upload more often like 1or2x a week?
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!
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
I have watched some of your vids, and you deserve a big thumps up sir!.
Have been messing with engines, bikes and so on, from age of 12 to now(30 year old) and you managed to teach me some new stuff.
Thank you and keep up providing these helpfull videos!.
Greetings from Denmark
Thank you! Denmark, wow that's awesome! I turned 30 this year also, this is such a fun hobby. Watching my kids enjoy it is most of the fun!
Why give a thumbs down? This guy is on point. Don't give a hoot to those ignorant people man. Keep it up. Your not doing anything good if you dont have haters... !!! Stay blessed.
I've watched a lot a great content from other UA-camrs with negative comments and thumbs down. I could film giving out thanksgiving meals to the homeless and people would still give a thumbs down just to hate. I stopped looking at that metric long ago and focus on the positives! Thank you for your kind words!
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 👍🏽👍🏽👍🏽💯💯💯
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.
This is the greatest how to video I've ever seen. Well done sir. 👏
Glad you enjoyed it!
Hey BJ that was a great video really clear and concise, thanks for taking the time to put this together, wish you did more videos. Thanks
Glad it was helpful! Thanks for watching!
Awesome video man. Very informative and like the fact that you talked about some of the tool necessary to do the job right.
Thank you! I know the video is long but I really wanted to make it all in one to cover everything you need to do the job.
im working on rebuilding two much larger bikes (both Suzuki 250s) and this has been the best video I have found on rebuilding a top end. Thank you.
Glad it helped! Thanks for Watching!
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.
I was putting mine back together right along with you. Great videos really helpful thanks.
Great to hear!
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
Happy to help! Those little Jeeps are so cool! Hopefully you get it back up and running!
This is the best video I have seen regarding rebuilding these things. Keep up the great work man!
Thanks, man. One of the bests video tutorials that I've seen. And very lively, too.
Great video,if it wasn't for this video I don't think I would've gotten my engine running,Thanks!
Another great video. Thanks for all the tips and tricks in this one. Did valves on one earlier this year. I missed a few steps. But I know for the next one. Cheers!
Thanks Mark! You bet man, I really felt UA-cam needed this video and I am glad I was able to help. More to come!
Just watched for the Timing, thank you very much for your help :)
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.
You're a special individual Hopefully life is treating you as well as you deserve.
Just bought a valve compressor after watching this you made it look easy 😁👍
If your going to do this job that compressor is a must have tool!
I love your videos. You really include every detail. I really learn a lot!
Best Chinese atv videos on the net.
Very much appreciate your tutorial video on. 110 top end rebuild ! I am envious of your. expert knowledge !Keep making those great video's ! THANKS !
Glad to help! Thanks for watching!
This is exactly what I needed. Great tutorial 👍
This guy is the real deal I subscribe right a way thank you for your time and effort to share this video with us.
I appreciate that! Thanks Nacko, glad you enjoy the content!

Hi BJ,
I just fixed it! Until your battle cry I had to do the same. thank you very much.
Nice work!
Thank you. Very complete and Confidence inspiring.
Thank you for explaining this properly. Ive tried watching other youtuber and found myself confused more than anything else
Thank you so much for this detailed video helped so much with clear to follow instructions
Nice that u help us help ourselves and in turn it helps you. Lol keep fixing everything u touch bro.
Will do! Thanks!
You did help me rebuild the top end of my boys buggy , liked and subbed . Thank you
One of the most clearest and most detailed vedio from my experience.
Love ❤ you brother from Pakistan 🇵🇰
Glad it hear you liked it, thanks for watching!
I really like your videos! I tried to do almost the same a decade before, but I not tried to sold my bikes. I have a lot of old communist and japanese two strokes. It was much more difficult with the two strokes. They had almost every time an ignition system with points. I currently bought a 110 (107) cc quad and it had a couple of issues. Your great videos were a big help!
That's awesome! Glad I was able to help!
Best instructional Video! Helped so much.
Great video, so glad I found this channel, I have a '86 XR 80 to sort out. Thanks ! 👍🙂
Awesome! Good luck on your project man!
Love the content and how you put it across. I have the 125cc and having starting problems.
Great job , this helped me understand my atv and bike
Great to hear!
Very nice job on the video. It helped me with a project I had going. Thanks
Fantastic video as always,really teaching people what's what. Can't wait for the next video mate.
Stay safe all
Always happy to hear from you David! Glad you enjoyed it man!
@@PraskaBoysGarage always mate , really look forward to your new video's. Easy to understand know silly jumping around 100% quality
@@PraskaBoysGarage hello not sure how to send this message without putting it on reply. i was wondering where you got the little engine stand that bolts down to the table . ive been looking for one just dont know the right place to look. please and thank you in advance for your response.
@@mistiparker6272 This is my #1 question for sure! I actually had a CNC company laser cut out all the metal to start making and selling my own. I will be selling the kits on my website either as a DIY kit or a completely assembled and power coated. Should have everything ready soon and will post updates on the channel.
Looks very similar to my 200ccm, so great video. Thanks :)
DIY guys like us have no complaints about this tedious work....No pain, no gain! 👍
Have to put an (*) on that comment. ***Unless changing tires with inner tubes...
Ty , I'M LEARNING A LOT WITH YOUR VIDEOS..TY VERY MUCH...
Great work man I am a believer now
I love this guy. So informative
Thanks! Glad you like the content!

Haven't seen any new videos recently hope all is well .. thanks for all the knowledge you have shared you sure helped alot. Stay blessed
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!!!
Oh man, that's no good! Good luck with the repair!
@@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

Very Professional Thank You MotoBro
Thank god for you. Im sure my sons gokart has a blown head gasket. But didn't want to dive in untill i saw how the timing assembly was held together.
That cover bolt from the other side i never would have figured out.
Happy to help!
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
Glad you found the channel man! Good luck on your projects!
Excellent video.I learned a few things 👍
