Highly Detailed GY6 Valve Adjustment Procedure(Step By Step)

A Highly Detailed/STEP BY STEP tutorial on how to adjust the valve clearances on your GY6 scooter. Proper valve clearance is essential for ease of starting and peak engine performance. If you have never done this before(New to scooters), then this video is definitely for you. All necessary tools are listed in the video. Procedure outlined in the video applies to a few different engine sizes. If you need any further assistance, please post questions in the comment section.
Suggested valve clearance is .005" intake & exhaust, or .004" intake & .005" exhaust. Both will work. I have used this exact procedure for 3 1/2 years with no problems, and racked up well over 10,000 miles.
**You can find some replacement parts(Usually CHEAPER than Ebay) for your GY6 scooter at the link below. You'll also be supporting my channel. :-)

Just a tip for everyone else. It is definitely easier to hold the center with needle nose pliers and lock the nut with a open end wrench, especially if you've never done this before. Great video!

[@qu4980]

True. I use a .004 as a shim while socket tightening. When I yank out the 4 only 3 will fit. Good stuff

[@elobiretv]

Just buy the special took they make for doing this, I think you can get them quite cheap now.

[@edwardjames6070]

@@elobiretv I'm as cheap as anybody, and that tool is a MUST. search 'Valve Adjusting Tool For Scooters' it's a two-piece tool with one piece having 3mm, 3.5mm, and 4mm and the other piece having 9mm and 10mm sockets. great tool. way less than ten bucks.

Thank you for the video, my scooter seemd not having power anymore, despite new belt and Variator it was the valves, i adjusted the spacing and now the scooter seems like a jet! (Had a little problem with the gasket of the valve cover, so it was leaking a little oil, but rearranged the gasket, repositioned the cover, and now is perfect!)

[@electronicsNmore]

Remove the spark plug when the engine is warm, and screw in a compression tester and crank the engine to see if the compression is good. 125-150 psi range is a new engine. Anything under 100 is not good. You could have crud in the valve seats or require new piston rings. Thanks For watching! Be sure to rate Thumbs Up, and share my videos

Hey everyone, I have a 150cc Velocity scooter, and it slowly started to get harder and harder to crank. I would run the battery down turning it over until it would finally fire at the almost end of the battery life. I changed out everything that I could, since the symptoms of valve problems is basically no fire. This took my about 45 minutes, I used the sealant that he said, and BAM, my bike fires as soon as I hit the starter. This is not a hard job to do, and I hope you all get the help that I did from this man. Thank you for the video.

I will have to try this in the next couple days. I was riding for the second time ever (I have about 30 miles on it) and on my way to work, I went around a turn, and she just bogged down and died. So after some google searches, this is one of a few suggestions. This one sounds most likely it tho. Thanks for posting and I will update on results.

[@electronicsNmore]

Sounds like an ignition system problem. I have a video for that also. :-)

[@gregatron4528]

Problem Solved! You are exactly correct! I am just now logging on so I didn't get to see your reply but I'll tell you what happened. In this video at 4:32 "this pipe going around" .. That pipe on mine is shaped differently and it goes up and passes the ignition coil then becomes an insulated rubber hose. The ignition coil (or spark plug wire) was up against that chrome pipe and it had melted halfway through the wire. I removed the ignition coil, tested it for ohms, it checked out normal. Put it back, tried a spark plug test, it was a weak orange spark .. Plugged it in, scooter started up.. Til I kinked the coil where it had melted, and there ya go the scooter shut right down on me! so you are right on the money with the ignition prob.. Plus thanks for the help removing panels in this video. Knew what to do right away when I got home!

[@maxexelby7566]

Best video on the whole of youtube explaining valves. Quick question, what are the main factors at causing low compression in a moped/GY6 engine?

[@electronicsNmore]

Max Exelby Low compression is caused by valves out of adjustment, incorrect timing, or worn piston rings.

[@maxexelby7566]

cheers

[@coquikarts]

I like the video..!! I just want to add that I preffer to find the Top dead center by taking the spark plug of and carefully introducing a small screw driver. That way I am 100% sure the the timing is correct. A simple teeth off on the camshaft would give a degree.

[@electronicsNmore]

The timing marks should be accurate, but you can do it that way also. Thanks for watching!

[@jordanrowan2537]

Hopefully this does it cause I haven’t been able to locate an adapter for my compression gauge to check that I know the white one has low compression but it would do atleast 30 when it was running the green one was kinda slow but very torquey it would pull logs heavier than me and they are only 50cc engines

Thanks for the video. I've watched several of your other videos, and I've got to tell you, I'm a much more informed scoot owner thanks to you...anyway, I've got "hard, cold-start" issues, and I'll be adjusting my valves, because everyone pretty much says that's how to handle the issue. My question is, why does adjusting the valves help with cold starts??? Thanks.

[@electronicsNmore]

Thanks For Watching Larry. Be sure to rate thumbs up and share. If the valves are out of adjustment, the cylinder will not have the proper compression. Everything has to be timed correctly for proper engine operation. If the valve is too tight(likely in your case, then the valve may remain slightly open reducing compression making it harder to start.

[@TheDON1326]

I can tell mine were never adjusted properly in the fist place. I'm 65 now and I dunno' how I made it before KZbin or Google! :-)

Ok mate, will give that a go tomorrow. Thanks for the advice. Much appreciated.

[@richardconnell2677]

Had a look at the manual and it said .05mm on the inlet and .10mm on the exhaust, that is hell of a difference. I tried it as the manual stated, now Laggy, slow no acceleration. So I will go with your advice.

Thank you for your response. I am grateful for your help... I went ahead and did the adjustment, then rotated the flywheel 2 complete revolutions and checked clearance again and then closed everything back up..I removed the carb disassembled it and cleaned it all out + jets. It was clean to start but now it it is extra clean. Long story short - I do have fuel flowing to carb -I do have spark - no vacuum leaks -battery is good -kickstart does not work, sometimes it gets stuck. -electric start will turn but not engage the flywheel 90% of the time.. and it makes a horrible grinding noise 100% i press it. WHAAAAA??? What could it be? I am stumped!

I'm thinking of replacing the Carb, Clutch, Variator, and CV Belt all at once and hope it'll run much better. As for it's idle, it's always been stalling ever since I bought it, but now it always wants to take off on idle. Usually I give it a little gas so it wont but even when I don't I can feel it pulling away. If I do manage to hold it steady without gas, it stalls.

EGR (Exhaust Gas Recirculation) It takes inert exhaust gas and mixes it with intake air. Reducing the intake air from 21% O2 to 16% O2 will decrease temperature of the engine which will lower NOx (Nitric Oxide) emissions because NOx is formed at 2800F.

Please help me understand what I’ve found ok so I’ve looked at the wiring diagrams for this little quad relating to the ignition coil starting at the CDI. So the two pin single plug has one black wire which is the ignition switch input that supplies the CDI with power from there I moved to the 4 pin 3 wire plug and checked the pin on the box directly it reads that is a hot wire like it should be but magically when I plug the harness into it I changes to ground

The hole in the camshaft hole is in the correct position but the alluminium piece falls in place with the F line instead of the T line.I think something is wrong?

[@serkanbilici7457]

I had my cilinderhead changed by someone because my spark plug hole was threaded,so the guy who installed the new cilinder head didnt do a good job?

[@josejuanaguilarlopez6615]

For a gy6 motor 180 cc atv is the same procedure ? Thank you for your timew

[@electronicsNmore]

Yes. Thanks for watching!

[@dezyrides2519]

Any suggestions or tips on how to adjust them without the little measuring tool you slip under it? Should there be barely any play or none or alot? Anything

[@electronicsNmore]

Use a thin business card.....should work.

[@user-it3du5ed5q]

Ok so i get it done at 010mm intake and 015mm out and i thing it's better now thx :) But it still makes that (puff) sound like a lot air is escaping from some small holl

[@blaskedryck]

Sounds just like Tampatec!

[@electronicsNmore]

🤣

[@gadgetsgimmicksandtech]

At 3 minutes 32 seconds what is the big black hose in the centre, and where does it go to? I have a quad bike with this engine and it has this hose on the engine, but the other end is free with a clip on the hose so it obviously used to go somewhere but I can not find out where - thanks.

electronicsNmore I have a 2011 VIP scooter it starts and Idles at around 4K rpms then it dies I installed new spark plugs and a new fuel vacuum pump and I also have a new electric choke coming in what do you think the problem is?

[@electronicsNmore]

Could be many things. Check for vacuum leaks and also check the carburetor enricher. I have a video for that. Thanks

[@nathanfiliponi6670]

electronicsNmore thank you very much if you can give me a link for a vid on checking the vacuum hoses and I have a new enricher coming in thanks :)

[@thubb3628]

Thank you for the info. I would like to know, is there scooter still running. I see this was made six yrs ago.

[@electronicsNmore]

I used it for 5+ years, then sold it. Thanks for watching!

[@fatihpc]

Very good video. How many mm did you adjust the intake and exhaust settings?

[@electronicsNmore]

I should've said in the video

[@fatihpc]

@@electronicsNmore thanks. But, I do not know English. I don't understand for your subtitle.

[@keith23uk]

Happy to say motorcycle fixed!!! Had to do a good carb and jet clean out. Grit got in there somehow.Like wtf? haa!

[@erikbmiller4890]

Do you know which motor I have? Have heard that it is not a gy6 but am not sure and need to adjust the valves. Engine code is 157FM2A

[@chriscybulski3579]

Super helpful, thanks to this video i finally started my scooter in months. But it seems to be running rich, the idle is fine but once you get on the throttle it dies down. Does anybody know a way i can fix that ?

[@electronicsNmore]

Either the carb(I have a video), or old gas inside the tank.

[@ItalianSupercars12]

electronicsNmore I have a 150cc stock motor and both my valves have bent about 5 times in the pass month, what can be causing the valves to bend so often??

[@jonasDoguedeBordeaux]

hi I have a leximoto arrow it has just over 3780 miles will I need to do anything it starts ok

[@electronicsNmore]

Definitely check/adjust the valve clearances. Intake .10mm / exhaust .15mm. You'll need to unscrew the caps on the valve cover to access the adjusting nuts. Also unscrew the cover by the flywheel on top so you can line up the timing marks before adjusting the valves.

[@dreamblind2895]

I have a 50cc would the measurements be the same for the I and E? Cleaned carb and new spark plug but my engine will crank but won't start I am hoping this is my issue. Adjusting the valves this weekend. Thumbs up =D

[@electronicsNmore]

You can do .004 Intake / .005 exhaust(lower valve), or .004" on both.

[@CharlieRocRevolution]

Great vid. I brought an older scoot and that pipe over the valve cover is missing. What is that pipe called and what's it do?

[@electronicsNmore]

It's an "EGR" cover. Exhaust Gas Recirculation.

[@scottsullivan7716]

Mine has that and a PCV circuit. Love my 06 Kymco GrandVista 250.

[@MIJusticeLeague]

I'm doing this valve adjustment now and when I get it to TDC I do not have that big hole between the two head bolts. There is however a small hole and a larger hole but I'm not at TDC when I have the big hole where you explained.

[@electronicsNmore]

Everything must line up as shown.

[@sandeepgc9668]

I dont have a feeler gauge at the Moment,what do you guys reckon to substitute that.

[@electronicsNmore]

Do it right.

[@fester16100]

this look a lot like the kymco movie 150 2013...how does the matt come off to get to the screws under it...? I wanna change my plug..

[@electronicsNmore]

Every bike is different.

[@zapurdumbass]

Found this video last night after many suggestions that my rough start of valve tolerance related. New GY6 and new 24mm Carb, could this still be the issue? I have to hold the throttle open to get it to stay running during cold starts. After about 1 minute it idles fine. Is this an intake valve characteristic?

[@electronicsNmore]

Sounds more like a carb/enricher problem. Check out my GY6 video playlist below and share. Thanks! kzbin.info/www/bejne/a6fPYqCoibt2h5I

[@zapurdumbass]

After adjusting the valves, they were definitely tight, but the issues persists. Your enricher/auto choke video is excellent as well, and that’s next on my list to check! Thanks for the excellent videos and suggestions

[@mike-gq4lc]

I have a gy6 with low compression that doesn't start. I am aware that this probably has nothing to do with my issue. I can get the exhaust valve to wiggle but the intake valve will not wiggle at all. Even after turning it more than once and lining everything up it still has no play. Is this an indication of something or? Any help appreciated, thank you!

[@electronicsNmore]

Hi. Both valves should have SLIGHT play when the timing marks are properly aligned. Keep loosening.

[@rkstew]

I'm thinking about getting a GY6. Are you happy with yours? What make do you have?

[@electronicsNmore]

Loved it. When I moved, I sold it. I had it 5 years. It was a Kaitong Velocity 150cc
