    Great and informative. Thank you. However you skipped the part of how to put the feelers in there, and went to the cover being put back on.

    I didn't see anything about adjusting the valves. Is this all about the fly wheel?

    Im sure you have already heard or seen it in the comments but this video os 100% useless . I actually have had several people bring completely destroyed engines because they used your video on how to adjust your 49cc Chinese moped valve train . I should probably be thanking you because your vidoe has put money in my pocket more than a few time , so , Thank you ! If you are still posting videos , or planning to post more , maybe you should hire an editor or let someone attempt to do what your subject is pertaining to , this way you get real world feedback , in real time or maybe make yourself a step list , a detailed step list , then go and prepare your work area , ex: Lighting , camera position , neatness , accurately chosen tools and or accessories . I was told by a very seasoned aircraft mechanic who retired from the USAF after already being a multiilloonaire for close to 20 years ( so i trust he knows what hes is doing when it comes to wrenching on about anything . Presentstion to the public is important . Tooling : having adequate and correct tools for the job . Sockets , extensions , universals , high ratio wratchets , especially on anything 1/4 inch drive does not need an impact to loosen or totque anything , Especially on any of this Chinese or Korean made emgines . Everything from the engine blocks , to the parts inside them , the nuts , bolts , screws , lock washers are all made from cheaper , inferior processed , and manufactuered steel and aluminum unless you want to do some drilling , tapping , and rethreading . Cordless impacts are a NO NO ! The erong person with a cordless impact driver can really end up costing himself more headaches and more aggrevation and discouragement than the entire job was worth to begin with . This is just a few things i picked up right off rhe top and thought that rather than pointing out what you didnt do in the video , because im sure you already know , but to share a few good things that would make your tech videos of anything , just a bit better . One last thing , valves in a Chines MOPED engine do not make the same clattering , clicking , or knocking noise that they were making when the thing was brought to you and when adjusting the valves do it on a cold engine , check the previously set adjustments and if the drag on your feeler is loose , try another feeler either up or down in thickness and note this when you adjust them , make sure you are not putting pressure on the rocker arm because this will setnyou up for bent rods , valves , holes in your heads . Take the noted lash adjustment and adjust the valves based on how much drag you feel when checked first , if there is an obvious looser feel then take the first number on the intake side and jump up to the next feeler , if it fits and has the right drag feel then then note the feeler guage size and go to the exhaust side and repeat . Now you have a beginning , or a control parameter that you can go by

    Hello, that is the normal sound of the engine? It still has a knocking sound just like mine and I heard at another scooter same engine, the sound was without the metal knocking...

      They should have a slight tick . That is the valve clearance . If no tick the valves are too tight .
      Honda motors especially the 400cc atvs have a much louder tick because of bigger valve clearances . Perfectly normal . That is the .05-.06 clearance on the exhaust valve .

    Step by step? You left the actual valve adjustment out! Wasn,t that the point of this video...anybody can just remove and replace covers/screws ect..
