Does the50cc gy6 have the same torque on bolts

[@Attilla7]

And since I have it apart is there any thing else I can do to help it out I have the big bore, A9 cam the 1500 rpm clutch spring 6gm rollers and the pwk 21 mm car and high performance Cdi and coil and a straight feed gas valve and header

[@GTAIVisbest]

@@Attilla7 Yes, the only real difference I know between the 50cc and the 150cc is the clutch axle nut - on the 150cc it's the same size as the variator nut, so it gets 60NM, but on the 49cc it's smaller and only gets 40NM. With regards to all other bolts, follow this general rule for any china cases: Any generic M6 bolts (usually 8mm) - 5NM Engine case bolts (that are usually also 8mm, but long and hold the case together): 7NM Any generic M7 bolt/nut (usually 10mm) - 8 or 10 NM Cylinder head nut: 13.5 ft lb The rolling wrench general torque specs for GY6 page has more information, but keep in mind that many torque values there are too high because of the bad quality metal used in china cases - For example, they say 10NM for M6 bolts, but if you try putting 10NM on the CVT cover bolts or valve cover bolts for example, you'll strip them

Thank you inhave 1 question, 08:05 you say 7nm i did mine on 8NM because my manual says 0.9 kg M, and after that it broke the bolt

[@roymichaeldeanable]

[@Mprikiman]

Such a neat video! It's therapeutic! Subbed and liked! Really appreciated that you didn't put any silly music carpet over the assembly. I wish I had a mechanic that I could pay to work on my machine that way :).

[@warrenclyde2467]

Rebuilt B&S engines at 12 years old. Folks everywhere had one that did not run great. So few parts. Replaced my head on a GY6 as the muffler bolt holes stripped out due to vibration. Will replace cam with an A11 as I live in the mountains. I replaced my stock CDI as I was told it was limited to 35mph...bought a tunable one. Hits 55+ no problem and about 30 up hill. But she does not get anywhere near the 90 mpg suggested. More like 50 but all these hills eat gas...The last hill up to the house is nearly 2 miles. 9 miles round trip down to the hot springs. Takes like 15 minutes as I don't go fast on those twisty roads. But I get there and back on $.80 or less.

[@noneshere]

I remove the factory studs because they always strip out. I use 2" m6x1.0 bolts with a nut on them. Just screw the bolt in till seated, then turn the nut down till it compresses the exhaust pipe flange. It make removal easy too. Just losen the nut then spin the whole bolt out. Always use the fiber ring exhaust gaskets & and just slightly oval pinch them to get them to hold in place.

Great video, very detailed. One thing that could help more beginners like myself is if you could put some details in the closed captions for what your doing in that scene. Things like Torque specs as your tightening each bolt, which grease/oil your using (red vs clear vs blue...or was that thread locker), what the writing on the piston was for, etc...

Fantastic video your video are the best 👍🏻🤙🏻😁

[@vlennin2011]

Love the videos, I learned a lot from watching them and been able to fix most issues with my scooter... I did run into trouble with a 150cc GY6 scooter that keeps getting hot after about 15mins running, I tried everything and the only thing that keeps it from running hot is to "run it" without the belt for testing. Could it be a bent rod? replaced lots of parts..lots.

[@GTAIVisbest]

How did you diagnose that it's running hot? Performance? Noise? Temp Gauge?

[@vlennin2011]

@@GTAIVisbest I since got rid of the scooter, did tell the buyer all I knew and done. To answer your question, the scooter will start running poorly after 10 mins and stall or stop until cool so it was the performance and the fact that it was extremely hot unlike other scooters I worked with.

[@michaelwestman6272]

@@vlennin2011 I had the exactly the same problem with a 50cc GY6 scooter . I changed some parts, adjusted the cam clearance, then I thought I would change the oil. There was almost no oil in it!!!! Filled new oil, problem solved.😁

Hello i have a question for you i have 150cc gy6 and it started smoking from the muffler so i replaced the top end but its still smocking could you tell me why pleas and thank you

[@DevinReed-be4fm]

I would've tried to find what's causing the smoke for sure before I replaced the top end😅. Now it can be a vast number of things to find. Maybe check the rings and cylinder first?

[@zamdrang]

Nice to see a GY6 build by someone who understands how to put a motor together. Some of the YT videos of these builds are headshaking in how not to do it. Impact gun on the crank nut for example. Great job on educating people how to do it properly. Have to say the castings of those pieces look pretty cheap and low quality though. No way that motor will have the reliability of a Honda. I'll stick with the GET when the day comes.

[@RollingWrench]

Thank you for the support 🙏🏻💯. The GY6 A is definitely not quality casting. Never really had any issues though. If you want OEM Honda quality casting/billet build a GY6 B motor (made in Taiwan). But about double the price

[@thomashoyle1501]

I have a question. First some theory: The camshaft rotates 360 degrees to complete a period, likewise, the crankshaft rotates 720 degrees to complete a period. So the camshaft rotates at exactly half the speed as the crankshaft. Now the piston makes two up and down strokes(2 x 2 x 180 degrees = 720 degrees), so two Top Dead Centers (TDC) each period. Now I know for a fact that in an older scooter, besides a pickup coil(the fire signal) and a thermal sensor for the e-choke, without any other sensors than that, there's no way the cdi-box (besides the fact that it doesn't have any other sensor input than the pickup coil anyway) knows which one of both TDC's is the right one to send a voltage spike to the ignition coil and subsequently create a spark in the spark plug. My assumption remains that it sends a spark to both TDC's, that is, right before the TDC of the compression stroke as well as right before the TDC of the exhaust stroke. So the question is: Is my assumtion right, or did I oversee something?

[@cristianabrantes9190]

Does the back stage pass can access for all the details special the right lbs for all the bolts?

[@johng.3740]

I have a tao tao 50 with a big bore kit and I found out the hard way NOT to use non conductive loctite on the bolts for the stator. The stator creates a ground return through contact with the metal case AND through the metal bolts that hold the stator to the engine. When I replaced the stator on my scooter I put blue loctite on the stator bolts and then I found that the scooter would not start, digging deeper I found it had no spark. Doing some thinking I came to the conclusion that it must be the stator bolts, so I removed the bolts and cleaned off all traces of dried loctite and sure enough the spark returned.

[@RollingWrench]

The back of the stator should have made contact with the engine case. That’s an odd one

Question... what head can you get the most power out of for a gy6? A big 2v or 4v? And if not are there any differences really in performance characteristics?

[@noneshere]

More parts = more chances to fail. Theres hardly a performance difference in 2 vs 4 valves. Dont waste you money on 4 valve heads. They need special camshafts to operate those 4 valves too. 2 valve is common & rebuildable. There's even a 2 valve big head sold.
