Longbo Chinese GY6 Scooter - Weird Throttle Problem

I'm sorry about the audio on this. What I'm trying to say is that there's a new Gates Powerlink belt on it. I've never been able to compress the clutch spring by hand, but a local mechanic did so with ease. The clutch freewheels just fine. The thing doesn't "lug". Right about the time it would normally hit 35 or 40mph, it's as though the variator "tops out" and the drivetrain disengages. The result is that the bike "lurches". You can see the effect on the variator. I have no idea what to do about it.

Carb problem.

Check your intake for leaks.

Definitly to much air comming into the carb.

To me that sounds like a CDI problem like the rev limiter is kicking in.. I would try a new CDI they are only about 25.00...

CHECK YOUR VALVE TIMING WITH A FEELER GAUGE. Just youtube "adjust scooter valve" but try finding your specific engine on your scooter. Let me know how it turns out for you. Thanks.

Could this be a belt problem im thinking the belt is sligtly thinner than the original so its not getting the full way up the variator and with the cdi restrictor limiting revs it thinks it already at its top speed, my peugeot scooter does this as it resticted to 45kmh and it feels tho the restricter is cutting power to the ignition as its restricted by revs only on my peugeot scooter and as my belt wears gets thinner my top end will start to drop as the gearing ends up lower with thinner belt..

hey i have a jinlun 125 T-13 i had the same problem so changed the clutch and rollers and it kept doing it i then changed the belt but as its chinese its hard to get the right belt but if you get the right one mine did stop doing the lurching fora short time but to be honest iv spent alot of time and effort on my scooter and everytime it lets me down its constantly snaping belts at the moment. if i find out the root of my problem ill let you know it might be the same for you .
