Thank you geh. I am deciding if I should just get the stock top end or upgrade to bbk. I just found out that I have the secret 63cc too. So I feel sad replacing it with 49cc top end. If you are worried about cost I still recommend a stock replacement. Once you get into the BBK arena you have to worry about upgrading the crankshaft and other parts due to the extra torque place upon the engine and drivetrain. |

I love my scoot ,some might say they would never be caught riding a scooter . some think they are not " manly " I of course disagree . I have heard the same thing from some of my friends. What they don't understand is that I save a bunch of money not using my truck. It is also a very fun hobby. Besides, I'm married and have a kid. I have no need to empress with "manly" vehicles. |

Will you let us know what you think about the quality of this set when you receive it? That is a very good price and I will purchase one also. I'll probably skip of changing the clutch springs. I haven't messed with mine yet. I have not had any problems or complaints of my stock clutch. |

I'm not sure about the rest of you but I haven't seen any 50cc gy6 scooters in the sport bike style until I came across this one. 50cc Sport Bike I have seen the Roma and the Hornet in the 150cc version but this ups the game a little in the 50cc category. What are your thoughts and have any of you seen one of these? I think riding it would be a HUGE disappointment. The very aggressive body style would be ruined by the slow engine. |

Typically TaoTao are set to be very lean from the factory to adhere to emission controls. Tuning the card will fix that.
Valve clearance, or lash, is also set very tight from the factory. That's why from the factory the valves are very quiet. Once adjusted properly you will notice a faint ticking. Once the ticking goes away, you'll know the valves need adjusting again.

Okay. The first thing noticeable is that the engine was running VERY rich. That is why your spark plug and piston are black as night. Once the scooter is up and running the carb will need to be tuned. To do that access is needed to both the fuel mixture screw and main jet. You may be able to get away with just the fuel mixture screw, but both are preferable. That can be done by unrestricting it or purchasing a replacement online. Carb tuning guides are available in the tech library.
Next will be servicing the motor. Replace all fluids for the engine. Not sure if it is 2 or 4 stroke, but you need to be sure you have good lubricantion. Next would be the decision of if your going to reuse the piston and cylinder wall or replace it. If you go with a stock 49cc replacement set, the cost is not bad. A replacement piston and cylinder wall would be preferable since there was that huge scuff mark on the top of the piston. Once the engine is put back together next would be checking the valve lash. Intake and ex take valves for a 49cc should be .003 inches.
After the engine would be dumping all old fuel and starting fresh. With the tank empty check all fuel line connections and replace the fuel filter. They are very cheap.
Next remove all those emission controls on the scooter. They may also be partly to blame for the poor condition of the engine. Instead of allowing the engine and gas tank vent to the atmosphere, they recirculate dirty fumes back into the cylinder to "burn". That burning is very inefficient and ruins the air/fuel ratio. Removing those allows only clean air and fuel to be burned.
Those steps should get you back to a fairly decent working order.

If I want to replace the engine, it would cost me about $250-$300. Otherwise he would give me $175 for the moped because the frame is still good. What kind of budget do you have for this project? Do you want to just get it running with a few problems, or a reliable working order? |

Thank you that sounds like a great idea, I've been poking around and doing research trying to make sure that before I open it up I will have enough know how to complete the task! The CVT looks the only part of the scooter I know nothing about lol. I may end up getting rid of all of the emissions control stuff first even though it wasn't on my radar until the other night. I think people should leave their emissions equipment on. It's there for a reason and doesn't seem to affect performance unless it's broken. I know people like to simplify things to avoid problems but if why trash the environment for no good reason? I also think it's irresponsible to encourage people to remove their emissions systems. It's just asking the government to "crack down" on the scooter community. Where I live we don't have scooter emissions checks, and I'd like to keep it that way and avoid the hassle of yet another government program. Just my opinion. For my TaoTao the emission parts were garbage and poorly designed. I was getting fluid buildup and leaking in my air box. Besides these scooters are ever small engines. They do not produce a lot of emissions. We are already helping the environment by not cruising around in a cage. The least we can do is not destroy our engine by pumping dirty fumes back into it. |

My rectifier caught fire and melted the plug on teh harness and i dont know where the wires plug in on the new one. Can someone assist me with possibly a picture. i have a 09 Longbo LB50QT-22 to be exact. It is a 4our pin rectifier. If no one has a picture of your rectifier/regulator let me know. I have been studying and researching the topic for a month now. With a voltmeter we can easily determine your setup. |

i also voted the cvt. upgrade the variator to a Koss 115mm. i believe the 150's come with 108mm stock. it is the only mod i have done on my 150cc. increased my top speed by 7mph and dropped my rpm's by about 2,000 at 45mph. easily the best mod you can do for a 150cc imo. Did you have to change anything else with that modification, belt / clutch? |

I voted CVT, but even if you are not replacing the carburetor, the first thing should be tuning and jetting the carb. In the technical library of this forum is a very good walk through by alleyoop. After that move on to the CVT. Let me know if you have any questions. I have the exact same scoot. |

Ok well I am new on here. I just thought I would introduce myself. This is me. Yes that is me the guy that is sitting behind this keyboard right now. No smart phone for me. welcome to the forum. Typically people create their own thread for an introduction. |

Sounds like your scooter is on its last leg. I would be worried about safety with the amount of problems you have had.
