Love the work bench!

What happened ? I would have liked to have seen it put back together did you give up on YouTube? You did a super job at dismantling it and being informative. I thought cool I'm going to get to see this thing go back together but to my disappointment it did not occur. Otowela...

I love these Chinese copy motors!! they are super easy to work on, build up and the parts are sooooo cheep!! They are also really reliable too, NOT junk like everyone thinks because they are Chinese.

i learned alot.......thank you

Omg I know this guy!

This is what I would do. Steer away from spending money on an exhaust until you go big bore or stroker. Buy a DrPulley Variator and 11g Sliders. If your running a 24mm carburetor, search for a 26mm such as the stock 150cc TGB scooters. Next buy the A10 camshaft and port the head and intake...Once you port the head, the intake, get the 26mm carb, and install the camshaft, its OK to buy a performance exhaust...Nothing with an exhaust tip larger than about 1in or you basically bought a megaphone with little to no performance gain.

Loctite! Not to mention the crank case pressure going over 10K rpm starve the crank for oil.

OH, the timing chain tenser on these go bad and lose tension! so I would stock up on 1 or 2 extra ones. The oil pumps go bad too.

just remove the after market oil cooler, remove the cap from the engine breather and the engine should run fine

I'm buying the pre bored 150cc gy6 crank case and 61mm big bore kit I have a bone stock 150cc gy6 on I'm ordering all new oil seals oil pump etc will bearings interchange

thanks soo much #teamgy6

Did he run it low on oil. ?
