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!

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.

[@MrLachlan21]

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.

[@PraskaBoysGarage]

Love to hear that! I am very happy I was able to help getting your kids riding again!!! Thanks for watching!

[@danieldelarosa8806]

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.

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.

[@ItsLimNZ]

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..."

[@erictaylor2100]

Man when you put that sprocket on the head you made it look so easy I'm having so much trouble

[@PraskaBoysGarage]

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.

[@WillLockwoodStudios]

I have a 110 quad that runs, idles great but when it goes to rev it Boggs or goes super super super slow. I put brand new carb and tried tuning, had all my buddies try to and it wouldn’t fix it. I put new cdi, new spark plug, new coil and more. Figured out it’s low on compression. I have the engine off and apart. I did the flashlight trick that you taught and absolutely no light is coming through. The head and the cylinder and piston all look great. However, the head ghasket is ripped (not from me). I believe that is the issue and I will keep you updated. I have a new piston cylinder and all new parts on the way

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.

I would have checked the valve lash on the intake first before taking the head off. Had the no compression problem and that was the fix.

True. I didn't think to talk about a few things to look at first. I mostly wanted to focus on the rebuild part. If you have fuel and spark the next steps should be to check the valves and also make sure you didn't jump timing. After that start the compression test.
