Scooter Ticking Or Tapping Loud? Try Adjusting You're Valves 50cc-150cc GY6 

The problem is the set that I ordered is too fat and doesn't go all the way through. Gotta love China mold casting

But yes I am aware of how the tools should work 😆

Yeah the Chinese stuff is really wonderful crap. Just letting you know I wasn't trying to make you look bad at all your video is pretty informational.

Awesome

@@IFixShet looks like both need adjusted based on you video it was a easy task I also changed spark plug and gapped it out and it started right up with small carb adjustments next I need to take on broken bolt in muffler mount again thanks for the video you saved me hours of troubleshooting hope to see more videos

No problem

Thank you

then you didn't do something right

Every 2,000 miles

Also how can I fix the carb now I messed with those screws what’s a good start point without being to have the scooter idle ? Am I better off buying another carb I have out so many parts into it based off RU-vid videos and can’t find my real issue I had it running, had to full throttle to keep it on til it warmed up then it died on me and hasn’t turned back on since

New cdi new spark new spark connector cable new fuel line fuel filter new carb

Did youbcheck carb? Clean it? For carb adjsut just turn idle screw all way ight than back 2 and 1/4 turn. Idle screw is on right side on carb where trottle is. Screw right to increaee idle. If it runs on full throttle i think carb might be cloged(when you play trottle gas squurts in carb, should increase engine speed or if you squirt gas with syring or starter fluid)

@@merabiamkoladze5929 changed magneto got it running made a knocking noise which was terrifying died again won’t turn over at all now I’m giving up and ordering. A new one Ina. Week or two lol

Time for new rockers

@@IFixShet I forgot to mention, it only has around 600 miles.

@@FinznFowl82 So here's the deal these are called tappet Valves They are supposed to chatter however heavy ticking Not good. You speak because you have a new engine does not mean that it can't have a problem manufacture defect these are Chinese engines Whether it has 600 miles on it or 10000 miles doesn't matter if it has a defect from the factory. You need to determine whether it's normal valve train noise by listening to other videos or If your scooter genuinely has a problemThat needs to be addressed

@@IFixShet I definitely understand there are defects from the factory as I've already fixed several other problems. 😂 I just thought it was worth mentioning. The vacuum needle(probably not the correct name for this part) in the top of the carb wasn't installed correctly and she wouldnt run over 25 to begin with. I just figured that out on my own with some luck. I also understand what you're saying about there being a "normal" ticking/tapping, so I may just let her run for a while and see if it gets any better or worse. Most videos from what I've seen makes this noise at idle or just giving it some gas on the stand when there was a problem with the inner valve spring. But the noise is exactly what it sounds like when the inner valve spring is broken, only mine does this at a certain speed as mentioned before and not when on the stand. I'm beginning to think that it just needs to be broken in further since it was running so poorly to begin with through the break in period. I believe I will run it for another hundred miles or so, adjust the valves again and inspect the rockers and springs better when I do so. I really appreciate your timely response and informative video.

@@FinznFowl82 I’m having the same problem. Although it may not be a problem. That might be the normal operation of the engine. Some cars have a noticeable tap tap tap sound. I just installed an 80cc and I have a lot of chatter. I checked the valve clearance several times. Everything is good. No loss of power. I was thinking the noise is the valves seating tight because the valve springs are brand new (tight)

Ebay, GY6 valves tool

Some scooters will just naturally tick

So true it’s a good engineering if it does mine is strong thank god

I have exact same and no tapping at .04 mm but I am nervous it is too tight even though manual says .04mm

@@williamkaye9029 yep just rechecked mine and 002/ .04mm is working great now. Minimal ticking though I still hear a little. From what I’ve found on searching round the 50cc is ok to run at smaller gap being .04mm on both I and E, i was just thinking that it being a BBK it might need to be bigger but i guess not. Smooth sailing so far but I’ll keep an eye on it and check it again in the next 500mi

same, originally mine was pretty tight at about .002 with little to no valve noise but kinda asking for problems once it gets hot and ive noticed a bit of crappy inconsistent high end power. changed both to .004 and it was way louder (sounds exactly like yours) however i was able to consistently get 30mph+. possibly unrelated but just so happened to struggle less under high load. my engines got some mileage on it tho, possibly have carbon buildup messing with the valve seats and the .002 gap didnt help it.

@@spp6849 Im in the same boat, about 4k miles on the crank/motor aside from the bbk parts, also i noticed a vacuum hiss once i turned it off when i had it at .002, and agree, too hot probably gonna end up being bad news sooner rather than later, mines back at .004i and .005e and i think im just gonna have to live with the tapping sound, ill just keep it with some good oil and change it every 1000 miles or so, add a capful of 2 stroke oil to the gas tank when filling up and keep the fingers crossed lol

I have 19klm on the clock witch is around 11k miles. I have a BBK air intake and stock exhaust and I keep the valve adjustment at .003 intake and .004 exhaust. That's on an 80cc gy6 4 stroke. It's perfect and runs great.

@@ArthVader09 can you explain further like the bike wants to die or does die?

@@IFixShet every stop it is normal rpm around 2k maybe then suddenly it drops about 1k only. It is always the case but some instances it really dies

I do live in Tampa Florida

@@IFixShet I need help with my scooter 🛴

I'm going to be honest man I'm totally out of the 3DR world now I have done my best to leave this behind me
