Hello all. I am new to this forum as I have found it on Google. I plan to stay, there are so many scooter forums. I never really wanted to get down and nitty gritty with the scooter but Its looking like Ill have to. I have a 2015 TaoTao Scooter, 49CC. It has about 1200KM on it now. Everything has been fine. I have put a new exhaust on it. And a new NGK spark plug. This was all done a little while ago. Today I went to start it up and it started fine and idled fine. I have the idle set a little high. When I put it on the floor stand, I noticed the back wheel spinning. It was fine before, I set the idle right before the wheel spins. I turned the idle down and I had to turn it almost a full turn to get it to stop spinning, now the scooter has a really low ide but runs. As I went to take off, the power is really slow and then it feels like it catches into gear. Then as I'm taking off, it feels like its stuck in first gear for so many seconds with a high rev, and then kicks into another gear with a jerk.
Never had this issue before. Just changed the oil to Mobile 1 Synthetic and it has a full tank of gas. This is driving me nuts, all hoses all look nice and tight. Is this a clutch problem? I took the cover off and looked at everything but don't know exactly what I'm looking at. The clutch seems fine. Put it all back on, went for another ride. Same thing. Once it gets past that first really long high revving gear, it jerks into the next gear and rides good. Any help would be appreciated. Thank you guys!

 Grab some popcorn. Sound like either your belt gets stuck in the rear plulley, or something is wrong with your rollers. |

Your variator may be hanging. Disassembly and inspection is likely in order. How-to info on board here.

Thank you guys. So this doesn't seem like a clutch problem? The belt was fine on there when I took the cover off. Oh man this seems like its going to be a pain!

Thank you guys. So this doesn't seem like a clutch problem? The belt was fine on there when I took the cover off. Oh man this seems like its going to be a pain! It isn't gonna be as hard as you think. The belt drive is really simple once you stare at it for a while. The best part is that a brand new clutch or variator is cheap. Your engine is a 139QMB GY6 clone. All the 4 stroke 50cc Chinese scooters use this same engine or a variant thereof so parts are easy to come by and cheap as hell. If you search Ebay for "GY6 50cc Variator" or "GY6 50cc clutch" Or " 139QMB variator Chinese scooter" you will get results narrowed down to your engine. The other thing is don't get hung up on the Tao Tao brand name. These little China 50cc 4stroke scooters are all the same under the body so a 50cc variator for a Roketa, Peace Sports or a Jonway will fit a Tao Tao. 139QMB GY6 is the common denominator. Good luck.  |

The bell is what your clutch pads grip against to drive the wheel. If you turned it and the wheel did NOT turn, then you would have rear gear problems. The axle is attached to the clutch bell and the bell is locked to the clutch when engaged. I agree you may have variator problems which are easy to diagnose and fix. Maybe your rollers are hanging up? Pull it off and look at it...the problem may be obvious...maybe not. Bill |

I'll have to pull them both off. People told me on another forum That when you hand turn the clutch, its not supposed to turn the back wheel?

If your belt moved with it then that would be an issue.

They probably meant turning the clutch itself, in that case, the wheel should not turn. Just a misunderstanding I think. If you turn the clutch bell and the wheel turns...all is well and, if it turns freely, (and the belt is not turning) it means your clutch is not locked to the bell. Bill |

To me it sounds like you need to adjust your carb properly and check to see if your variator drive boss is hanging up.
My bike did something like that when I drove with my cover off and got caught in a tsunami. My variator appeared the have rust or something on the drive boss and shaft. Light brillo treatment and it has been fine since.

I have to check this tomorrow. I'm getting mixed answers. When I hand turned the end piece of the clutch, the back wheel moved with it. I can't remember if the belt moved too. I'll have to see tomorrow. I'm guessing ill just have to get another clutch? This scoot has 1200km on it. Like 700 miles. Belt looks good. This really shouldn't have happened so soon.

Thank you. I see. I turned the bell and the back wheel turned with it. I believe the belt moved also.

The bell is not connected to the clutch. The clutch sits inside the bell and it spins when the engine is running. When you rev the engine, the increased centrifugal force makes the clutch pads move outward and they grab onto the inside of the clutch bell setting the wheel in motion. That's why it's called a centrifugal clutch.
These videos will show you how a CVT and clutch work. really simple.
This shows a clutch with no bell on it. The pads move outward when you rev the engine
This shows how the weights/variator and clutch work in unison to shift the gear ratio.
