Do you have a scooter that is hard to start? Perhaps your scooter doesn't start at all. Or maybe even still your scooter starts but it wont stay running! A valve adjustment might be just what your scooter needs.
I was inspired to make this video by questions asked in the comment section of another one of my videos!
If you have a suggestion, or an idea for another episode of scooter 911 leave it in the comment section!

As a person with a Master's in Training in Industry, this video is one of the very few that is actually well presented and effective. In short, most how-to videos are extremely poorly done... this one is the exception. Well done!
Thank you so much!
Well said.
@@Scooter_911 I've just put a big bore kit into my yamaha cygnus nxc 125cc and find it very hard to turn over on the starter motor and end up finding it is still hard to kick start eventually I start it.after looking at this video do you think it's timing or valve adjustments. Regards joe
Will this work on my bike?

as a guy whose iq is in the top 1 percent, if you want an arg from authority, he is right. It pisses me off how many people don't even try to understand how to do things. True genius is making things simple and easy anyway.
My Business Planning class instructor said the same thing about investing in stocks yourself by reading the reports vs letting a money manager do it.
He claimed with just a little bit of work it was very easy to beat the market

Just a disclaimer, I've never worked on an engine in my life before now. This video helped me fix my scooter that hasn't run right since I got it. I've had two older mechanics look at it, replace over a hundred dollars in parts, and this video saved my scooter. Thank you so much!
Congratulations! That is so great to hear! But make sure you give credit where credit is due, YOU took the initiative and had the confidence to handle the job and for that I applaud you! Thanks for sharing your victory!
So if you mess up what the valve lash supposed to be when it's bottom then? None? As in closed?
This is probably the best valve adjustment video on UA-cam. Brilliant explanation of everything.
Thank you very much
Buddy I just finished doing the valve adjustment on my 2019 Tao Tao powermax 150cc that I thought I was going to have to junk. Let me tell you it was instant success. Thank you thank you thank you. Outstanding, keep up the videos. I've never worked on a scooter but you made it easy.
Thanks man, scooter wouldn't stay running, followed your tutorial and im back in business. Easier than I thought.
Try Hard
Thank you. I bought a scooter that would not start cold without cranking for ages. I was going to rebuild the whole engine, but saw this video then checked the valve clearances, the exhaust valve was being held open, set the adjustments to your specs and it started within half a rotation!
Thank you!! I spent over a year troubleshooting my 2018 50CC Taotao with no success. I changed carburetors (twice), new spark plug, checked fuel lines for leaking air, checked air filter, adjusted carburetor and replaced jets with different sizes, and many other things. I finally came across your video, made the valve adjustments and now it runs better than ever before! Too bad I couldn't have found your video sooner. Thanks again for your detailed demonstration.
Just tried this because my scooter would start extremely hard. When running, my tao tao would have this ticking sound. After I adjusted the valves it starts and runs much smoother and no more ticking sound. This video was very thoroughly and is a great guide for UA-cam mechanics like me.
This is like the Mr.Rogers show of scooter repair.
My mind is blown from how happy i get when ibhear the sound effects of every screw that gets removed. this is the most helpful tutorial I've watched in 2020
Just adjusted the valves on the 50 dollar taotao i bought. It would start but not idle or respond correctly to throttle. Idle problem solved and after carb tune it runs great. Subscribing. Thanks for the video
Amazing. I just did this valve adjustment following this video and my hard starting problem and weird idle...are gone. Both valves were off a little bit, the tappets were making slight contact on both ends. That tiny little adjustment FIXED my problem? I can't believe it. Thank you. I feel smarter now. haha
watched whole scooter 911 series.. what a presentation.. carefully made and planned... this is what professionalism is. learned a lot. thanks a ton😋
Thank you very much! I hope it helps you out!
That's exactly how I adjusted the springs on your mom's mattress.
@@Scooter_911 your videos helped me a lot. I hope you keep making these vids because I need them. I just got my scooter and it started out fine, then the issues started. I bought mine used. However, I do have a question. What can I do to make mine go a little bit faster? I'm in a hilly area and my weight is over 300. When I go uphill, I'm lucky if I can hit 17 mph. Any suggestions?
I been working on cars all my life and now 53years. You have talent for teaching 😊. I subscribed 😊
Great video. I like how you speak clearly and go slowly. Much appreciated!! Big 2 thumbs up and a definite like!!
Thank you very much! I work pretty hard to make sure everything is pretty understandable.
Picked up a 09 Sym HD 200 it hasn't been started for 5years or more. Fresh fuel, sea foam and new plug. It starts idles for 30 seconds dies and I have to wait for a while before it will start again also to get it to throttle up requires spraying a fuel source into air box. What do you think
Man you have helped me with my rear brake sensor repair (didn’t know it got caught and broke). Now this video! Wasn’t getting the speed I should and rejetting wasn’t solving it. This was it! Riding WOT all the time this is a must!!!
You're not mechanic only, you are good speaker and teacher too, thumb up!,👍
Thank you thank you thank you thank you!!! I would have never got this without this video and my small engines class in high school…
This video is fantastic, lots of good information, clear and easy to hear/understand. You don't have nearly enough subs for such a high quality channel. Never change
Wow thank yo very much! I'll try!
Wow. This is so thorough and clear. One of the best UA-cam's I've seen.
You're the best. Been watching your videos today as I just relocated to Hanoi where 95% of the city is running on scooters and have little knowledge of repair or spotting issues when looking to buy. Granted repair is cheap here, but no one likes being taken by a shady mechanic. Keep posting and keep up the great work!
Oh man you're in scooter central! If I were you i would look for a newer PGO. Very soundly built engines, lots of available parts and plenty of modern amenities. Thanks for the compliment!
THANK YOU SO MUCH! I was going mad replacing parts trying to fix this issue. Even had a well known shop tell me it needed $700+ worth of work when it was just the valves that needed adjusting. So glad you took the time to show us how it’s done.
The sound effects slay me, dude XD
Also thank you, I FINALLY understand what valve adjustment means!
I've been watching these videos for so long. It motivated me to get my own scooter because I was afraid of the maintenance. However you've made it so easy. Thanks so much my dude
Hi Garret. I'm really grateful for your guidance. Had exactly this problem on my little Gomoto 150 cc and your video worked like a charm. Thanks a million buddy. Ash
I have made my scooter worse from the other valve adjustment videos… I never knew you had to remove the spark plug, or where it was on this exact model (definitely messed that up the first time I tried to valve adjust). Thank you so much for this tutorial and these tips!
So glad to help!
I've never been into mechanics stuff, but I LOVE the way you teach. You drawing it out and giving clear explanations helped me wrap my mind around this. Keep up the fantastic work.
The video game noises were a great touch btw 👌🤣
I wish i had a knowledgeable small engine mechanic like you living near us...
Thanks Garret for as you say, "empowering me to fix my own scooter...just a bucket of bolts..."
Bought a brand new moped that wouldn't stay running. Followed your guide and I was able to ride it around the parking lot finally... You saved me a bit of money, thanks for the great video!!!
me too...and idling stop on red signal also no ignition for restart at very dangerous traffic.
I am wasting a lot of money and time on a new brand pony50.
never again buying cheap price, made in ...It is kind of scam against customer.
Thanks so much for posting this video! With this information I was able to do a valve adjustment myself and improve the performance of my Chicago Go scooter. Keep up the great work!
Love you man! You have helped me continue to ride several occasions as ive always been a do it myself er and i have continued to pass on your knowledge and repairs to many others. Its surprising how there isnt any scooter repair shops in my city not even parts... There is one scooter issue i cudnt resolve with youre or any videos online and that was a non starting scooter or once starting but not accelerating after replacing belt that tore while taking off luckily i bumped into an ex mechanic of closed shop that told me variater weight can shoot around if belt splits while driving and i made sense and thats what it was i was soo close to juat trashing the scooter lettin it go for parts and that was the only problem search for it online u can never find an answer for that repair im sure many are sitting with that issue....
This video is amazing! Instant sub... Great pace and detailed explanations. Loved especially the whiteboard with the theory on what should be fixed.
Thanks dude! Glad you liked it!
This video has made me way more confident to try fixing my scooter (2005 Kymco People 50). Thanks a bunch for making these and posting them. You clearly take a lot of time with the sound effects (I laughed) and the multiple camera angles. Grateful for your content!
Thanks bro, I'm a mechanic, and it took me forever to realize it was the valves, the exhaust valve was tight against the rocker. Just loosened it a bit and it solved it. Thanks lol
Hahah I'm a technician as well and I can't tell you how many times a quick drive down UA-cam lane has given me the boost I needed!
That was just about the best mechanical "how-to" video I have ever seen. Thank you!
Thank you very much!
@@Scooter_911 Thats amazing 😉 Infact me too i have a scooter 150cc cityblade which had the same problem.Ive brought my scooter to several mechanics but in vain.1 ve spent lot of money replacing the carburator, brake switch ,starter even they told me to buy a new camshaft.Thanks God after watching your video i mustered all my courage and followed your step.The only thing which I bought is the milimeters thickness gadget.Once again am grateful to you.Thanks 😉😉
Awesome vid bro. You are an excellent instructor
awesome video, fella! entertaining and very well made; extremely informative
Very good video. I adjusted my valves my scooter runs better than when the dealer did it while back. Thank you!
Thanks garret. Confidence inspiring. I wish you taught my accounting classes in college.
Nice job man! Very well done and professional 🥸
Great production work, well scripted and executed.
Thanks for making all these scooter videos (really liked living with a tao tao). All the info and how you present it is just amazing. Currently waiting for my Pony 50 to arrive. I'm going to follow all of your recommendations. You are awesome!
Your awesome dude that was perfectly informational, I can totally do that to my scooter now
Just got my taotao and trying to fix it. Found your video and while I haven't tried the method yet, I love your video. Really breaks it down and your terrible puns/sound effects are fantastic.
So glad you liked it! Let me know if it helped you out!
@@Scooter_911 made the valve adjustment but I'm having serious trouble otherwise. On my page is a video of what it's doing. If you have a minute could you check it out please?
ua-cam.com/video/yHD0G7Sj0cg/v-deo.html
Thanks!
And btw, I've been looking at many a video, and yours is by far the most professional. The music is great, I love how you speak slowly and clearly as if you really want people to grasp what you're saying. Also the diagram you drew was huge! I'm not a mechanic, but I had a power mechanics class in school and my dad built an amazing model of a car aee-through engine that even included a whole chassis and working brake system. I say that to say that i know how engines basically work with the whole valves, pistons, rocker arms, camshaft, etc thing, so it was interested to say how that work on a small scooter engine!! Thanks brah!!
Terrific video how to step-by-step valve adjustment!! I just bought a 2018 Tao Tao ATM 50cc scooter, my second one in 8 years...thanks for the video!!
Thank you very much! And congrats on your new purchase! Keep it shiney side up!
German Torque Specs!!! Awesome video!
One of the best explanations and presentations I have seen! Thank you and congratulations! Would have liked to see it run after fix to come full circle.
Yeah in hindsight I should have filmed it running more. I thought the scooter starting right up in the final scene would be more impactful.
This videos soundscape has a don't hug me I'm scared kinda vibe :) This dude knows his stuff. I'll subscribe.
Brilliant, so clear and concise.

Thank you very much! Always glad to make an acquaintance across the pond!
I work on them. One thing not mentioned on this vid is the reason you have to adjust the valves is the valve in question is wearing the head out which makes the valve adjustment tighten up. If you are adjusting the valves often you might as well get ready to replace the head. And a valve adjustment will not always fix the problem if the head is bad.
Time for a big bore kit
Great stuff! I really appreciate these!
I just love you! I'm going to try this tomorrow! Thanks so so so much!
Make sure you adjust them at the right top dead center (TDC). The piston is at TDC two times per combustion stroke. There's a mark for TDC on the flywheel, that you can see if you take the plastic cover from the fan. Turn the flywheel until the T mark is aligned with the pointy bit on the crank case. Then check if the 2 holes in the timing sprocket allign with the edge of the cilinder head. The smaller third hole should pointing forward. Then you have the right TDC.
I did this wrong once, so you don't have too. 😂👍
Exactly! That is why I like to wait for the intake valve to close. Right after it has closed you know you are on the compression stroke!
@@Scooter_911 you are also right. It's just a double check with the markings. I am just about to set the valve clearance on a friends scooter. The scooter hardly starts when it's warm, and it doesn't accelerate anymore, well it does for a second, then almost stalls, then goes again... I was suspecting ignition trouble, but first thing I am going to check is the valve clearance. Second thing is the vacuum membrane in the carburetor, might have a crack or puncture in it.
Thanks Garret, great video, scooter now starts runs like new. Not being mechanical I appreciate the education.
That is so great to hear! Exactly why I made this video!
Very informative. Now I can dive on in to my Aprilia 200cc, but being careful that it is a bigger engine.
Oh and I like the Centipede music😁
Great helpful video, thanks. Cool editing with the music too! 😊
Incredibly glad to find a moped video that doesn't make me wanna rip my hair out this is gonna make my life so much easier (and cheaper) than going to the mechanic who tried to charge me 2k to fix my brakes
Well I'm glad that this video made it's way to a capable person ready to take repairs into their own hands! Good luck my friend!
Bro, thanks for uploading this and for taking the time and patience. Very helpful. You saved me a ton of money on parts I didn't need to buy and work that didn't need to be done.
Man that is so good to hear. Thats exactly why I make videos!
@@Scooter_911 so since March I've been scouring Craigslist for scooters and mopeds. I finally purchased an SSR Lazer 5, 4 stroke. 291 miles on it, basically fresh still. I adjusted the idle screw yesterday without much effect on the stalling issue and was prepared to buy an aftermarket carb, jets and cdi. I'll be doing the valves in about an hour thanks to you. I'll check in later with the results.
@@Scooter_911 ok I was able to do the valve adjustment. She's running much better now, especially idling. I do believe I'll take it for a long ride tomorrow and then fine tune the job I did. My engine is set up a bit differently so the feeler was bent a little bit. I may still have too much lash but nowhere near where it was. Again we're talking about a 300 mile engine so it was running on factory assembly specs and heat expansion/break in. Thanks again my friend.
Nice video brotha👍💪
I tried everything. This worked. Started right up. Thank you
Glad to hear it!
Worked on my dong fang 50cc, your a life saver thanks..
This dude is the Bill Nye of scooter mechanics
Dang! Thats high praise!
I hope not Bill Nye is so wrong so many times this Guy gets ti right
Laugh
Wow you just made me a subscriber. You explained this valve adjustment very clear compare to other videos. I would like to request for you to make a video on vacuum hoses and fuel lines for 50cc scooter thanks
Great suggestion! HOSES DEMYSTIFIED! Thanks for the comment! Keep it shiny side up!
I always had a problem setting valves in cold or hot adjustments. However, it was never explained as well as you demonstated. Again, great job. Thank you.
Amazing quality videos all of them you deserve more credit
Again thanks for taking the time to reply I’ll keep a lookout for more of your great videos-Allan los angeles
I absolutely love this video! I definitely feel empowered and encouraged! Thanks! Great info and funny. 👏
Yeessssssss!!!!!!!!! Mission accomplished!
@@Scooter_911 I own a Havana Classic 125. It's fairly new. I've done research on it. Seems like I have to change oil and filter often.
@@Silver-cl2bd absolutely! The engine design is much different than a car and requires much more frequent service intervals. Luckily it's pretty cheap if you do it yourself
@@Scooter_911 thanks! I'll definitely be working on it myself. I'll be subscribing and checking back on your channel for your vids! 🤩
Thank you for the AWESOME tutorial Video. Great Job! I found an OLD
2005 Chinese "Qingqi" 4 Stroke GY6 Scooter with only 700 miles, this will fix the issue.
Absolutely love your vids. In the middle of a valve adjustment now. Fingers crossed! It runs rough for a minute then does. Hopefully the adjustment solves it. It’s a 150 QMJ so I hope the clearances are the same.
Yes indeed! Those valve lash specs work for all chinese scooter engines!
Also loving the sound effects haha
(And puns)
Thanks! Keep up the great work
Thank you so very much for this video. I just did exactly what you showed us. I just took 3 times longer or more but I did it. What a feeling and thanks to you for taking your time to teach us.
Very helpful, and I love how much passion you've put into this video. THANK YOU!
Very good explained! Thank you! Please do video about carburator setting/tuning and stator troubleshooting(no spark)
Thank you very much! I have a plan for both of those videos! So stay tuned!
Dude you have my respect because you are so knowledgeable about what you're saying, you sounds like a professor to me i have subscribed right away keep it up dude, you are one of the people who makes youtube very interesting...thanks for sharing
Those are very kind words, thank you. I'm working on a whole lot more. UA-cam has done so much for me I'd like to be able to give something back.
Just tried this on my Taotao and it worked great! Thank you Garret!
Man that's so great to hear!
great tutorials!
Thank you very much! I work hard on them!
I just had this done at a shop. I'm really glad you posted this video so now I understand what was needed. Thank you
Glad it was of use to you! And even more glad you're taking your engine maintenance seriously! Good on you!
Put starterkit 500v30-84 starter would start. Doolllat

Thanks so much master mechanic. I lost 3days of work but I got my bike back on the road with one try awesome
It's like Ben Wyatt is showing me how to work on my scooter. Thanks for the video!
nice vid man. Will definitely try! Also the little noises on the bolt/hose removals made me laugh. The music in general is solid
Haha appreciate it man!
I find when you adjust them intake opening (adjust exhaust) -and exhaust just closes(adjust intake) it's a more accurate way and will give you a different lash than just the TDC method. The TDC method will work but not the right way. JMO
Wow I have not hear of that . And I am willing to try it. Thanks
Another awesome video! Thanks again !!
Great Video Brother!
I am facing the same problem in my kids scooter 50cc EFI and I shall trouble shoot mine with your guidelines.
Your presentation is very good, easy to understand and clear to watch.
Above all this, you have given highlights in description! what a beautiful way.
We can understand, how difficult it is to make such an elaborative presentation.
Thank you very much and Keep it continued... Thumbs up!
I do enjoy watching Garrets scooter videos there easy to follow and understand, thanks guy. I was wondering why you didn’t test your results before putting all the panels back in this particular video?
Thank you. im sure this might be the reason. I think ill engage a mechanic now I don't have all the tools and expertise to go that far. This looks more expect requirement.
Ms. Thandi, I performed my first valve lash adjustment on my motorcycle 50 years ago, it is *not* hard to do. Get yourself a cheap tool kit from Harbor Freight, (Google them), when they go on sale, (which is a lot). Make sure that all the tools you need are included in the kit. Buy a set of feeler gauges there as well, you'll pay very little money for all the tools that are more than adequate for this job. Next, take your phone out to your scooter and pause this video step-by-step. After you perform this job just one time, you'll have payed for you tools, and have a real sense of accomplishment!
PS, he didn't mention it in the video, but you should not make the adjustments when the engine is hot, (shortly after a ride), nor cold, (below about 50F degrees), because the clearances will change once the engine gets hot again.
I would love a reply if you do it!
Stumbled upon this video after having changed the oil, cleaning the piston/valves/combustion chamber, checking piston rings, installing a new carb, changing spark plugs ... Basically everything and still struggling to consistently start my scooter.
Have ordered a feeler gauge which should arrive in the next few days hopefully and will do the valve adjustments. Will check back in!
For the mean time, thanks for your very well laid out informative video!
Good luck!
Okay it worked! But still can't start consistently ... I'm thinking it's the auto enricher circuit, intermittently failing
Thanks for making such a clear, comprehensive and helpful video. I am a keen have a go DIYer, and after watching you video, feel I will be able to easily take on the valve clearance job. 🙏🏾👍🏼
thanks master
Hey bro, love the vids! Please keep it up! I just did this on my GTS 250 after installing some fun new malossi engine upgrades and driving for a few hundred miles more than I should have. Made a massive difference in smoothness and power delivery. I was surprised at how much of a difference it made.
Recently, I've been getting into video production.
I'm curious to know, what kind of camera are you using?
Awesome man! That's a killer kit!
To answer your video question, this video was shot entirely with a cannon vixia vf500 that bought off Craigslist for $60. In some of my other videos I use a Garmin virb for under-hood and action shots. I then edit everything in iMovie. I use the Imovie voice-over function and a Korg microkorg synth to put in my bloops and bleeps sound effects and I created all of my theme music in GarageBand. Hope that answers your question and then some!
What an awesome fun teacher!! Thanks man!
Dude you put out Great and well made helpful Vids, thank you... Cheers from Canada
Thanks man! I appreciate that!
Great video! Very clear about what to do. I have the same scooter and was interested in installing a big bore kit on it and would love to see you make a video on how to that correctly. Thanks again for the great video
stay tuned! I've got that exact video in the works!
I bet 99.9 of scooters on the road have never had a valve adjustment.
Smh
@@integrationofmanandmachine4714 I know , right?
@@slamboy66 yup
@B E you know all they do is put gas in it.
I bought my sym with 2500 miles on it, changed the oil every 750 miles, sparkplug 3 times, it's now on 24,000 miles and I've never checked the valve clearance, it has good compression on the kick-start, doesn't rattle, idles smoothly so I just use it. I've had a few sym scooters that use the gy6 engine and after checking the others first time when I bought them the clearance hadn't changed in the next 4000 miles , I do however check the belt every 4000 miles and replace at 15000 as having one break while riding can really spoil your day.
Valve adjustment a really great video. THANKS 👍
That was very well explained and I like the way you presented and edited the video. Thank you ❤
Thank you!
Dude, I love your videos. You explain them so thoroughly, it makes things seem so simple. I guessitis
Thank you very much!
