Chinese Scooter Valve Adjustment




What do you think about this video?

CrimsonDragon468: What kind of calipers are those, and where can you buy them?

Jude Cossey: Very helpful. Thank you. Now I'm going to attempt it on my scooter.

Wutzthedeal: I kept screwing up because I was dancing.

Josey Wales: I am assuming that the 10 mm was for the head cover bolts.

Forest Silverwood: I was confident I could adjust the valves, I just wasn't exactly sure how to get to it. I didn't know the front plastic plate under the seat was removable. Thanks! This was perfect for me. Just adjusted the valves and now it's running in neutral just fine again.

monkehbitch: Mute is a wonderful thing. 

snipas103: Its a 4t engine google it. :)

IplayMusic2: I agree Phil B. I gap'd my Tao Tao ATM50-A @ .030 (762mm) and it clacked so bad I had to take it apart again. This time I gap'd it with a better set of gauges at .004 (102mm) and it runs great. Good deal.

Hooverdarnit: Do you know how to change a broken valve spring on a GY6? Is it hard? Do I need a special tool? THX

M. WilkEGR: called a slip/feeler/ribbon gauge.

mydio: @MeestaNoName Do what your manual says, different bikes will have slightly different requirements so it's best to stick to the manual's advice.

Vaappa95: @alphanostrum 0.08mm is fine.

Wutzthedeal: I have to go learn somewhere else because there is nothing dancy antsy pantsy fancy techno about adjusting valves.

Erk815: @Tommie211093 thats 4 stroke engine, piston is under the valves.

The Stiver: "if you have a FRIEND use it"

daand12: exhaust is 0.10mm and intake also or 0.05mm for intake, but not for exhaust.

oakster702: Dose this work on a VIP 50 cc stock scooter

mikmorpheus: wow thx u, it was rly intristing ! 5/5

RiseAgainstRcoks: DJ karburator!!!

erik travis: i have 49cc garelli tiesse four stroke 2000 km, adjust the gap twice. 0,5 mm and 0.3mm.but there's still a rattling sound from engine.help plss.

447za: @The12Nurse I didnt find my wrench so I had to use adjustable ! You can check that clearance in your manual.

447za: @The12Nurse Have you tried to Google that what would be the clearance of that ?

backyardbiker: that item he has labelled as a caliper is not called a caliper its a set of feeler guages.

Brian Crawford: Great Tutorial... This made my valve adjustment a breeze and it was my first time!! took me about 20 minutes.. It will only take about 10 next time!

ttk93: Great video. Helped me a lot. Thanks. BTW what is the first song?

Anton Reinholdtsen: two stroke is best for engines under 900cc :P

447za: James Cain have you noticed that my measure is in millimetres not inches. The valve gap is just right what the manual says.

Robert Meutsch: where is the "other one" you speak of...?

robsonITALY85: uj nawet kluczyka 9 tki niema :D

Fluffygolucky: I was wondering where did you get the calipers? because I cannot seem to find them online or the ones like you have on the vid.

Dan Swift: The scooter must be warmed up to operating temperature,Roketa,Sunny and Taotao valves need to be set as intake .003 exhaust at .004 hot if you noticed you have some valve clatter the wrong setting can result in damaging valve guides and seats, valves that are too tight will burn and you will have compression loss the more the engine heats up to the point it will want to die and bogg down bad, but good video

john chapman: is this setting the same as the 50cc too

Tilemachos Katsalis: i have baotian bt49qt-9..i change cylinder and piston...now it's 72cc and i don't know how much must be the valves..?

Wabbit1961: They're called feeler gauges.

The12Nurse: @447za thats ok I understand why you used it. I dont have a manual but i had an idea that a .0025 clearance can give optimum result...

monkeyboycal: what does this do

Anthimos Aggelidis: hello there can i ask u something i have a 125cc 152qmi moter (gy6) i put a bigbore kit with 61mm piston could u tell me the valve adjust????mm

oakster702: Ok I have 49cc made it to a 100cc will that video work for it

daand12: IN: 0,05MM ( thats right ) and EX: should be 0,10MM.

Timothy Smith: Garbage video.

OnlineScooterGuide: A friend told me about your video

katie williams: This was a great video - saved us a small fortune when we did mine yesterday, but my scooter had to have the valve set to a different spec (called the manufacturer) - I have a question for anyone out there though, We have a JL50qt-6a (Jenlin) scooter (49 cc) and need to know what the setting for the valve would be on it... any ideas? Thanks all!

Jeff De Soto: music really sucked. Dont need techo disco. I just muted my sound. Haveing the torque values for the valve nuts and the valve cover would be helpful. It would really suck if someone broke off a bolt. I used to strong arm things, but then I didnt know my strength. Best to use a torque wrench when tightening bolts. FIY

Tommie211093: dude you have one strange cilinder....where is your piston and crap?

1967pugman: thanks for the info. I just redid the head on my scooter and could not find a book any where to adjust the valves or find the proper placement of the gear for timing. I will buy u lunch if u ever come to town...lol pugman

Ozkutin: whichever is the exhaust and intake valve?

The12Nurse: @447za no I haven't done that but check out this dudes video "gy6 valve adjustment" by "mattyoung17754" I haven't tried to set my gy6 to this setting but maybe sometime this weekend I might able to try this settings..hey what do you think is the best weight combination for the variator rollers for a 150 gy6?

447za: Yep, We dont put stick it into pc we have like little PDA but same idea as pc... Have a good holiday too.

viper221984: my quad has compression, Spark and fuel but not starting? how likely is it valves could be issue? is it worth taking engine out and head off to check? or s it not likely this is cause? Thanks

aseh08: no it's not normal the valve seals maybe loose" oil may come inside the cylinder causing thick white smoke coming from burning oil" you should provably change the valve seal on the valves""
