Interesting
Thought I got it from Gy6Racing ... but maybe not. Have 2 on the way from him now, so will report back in a few days when they arrive.
About the clutch:
Don't think there is a bearing problem - everything spins by hand quite freely.
But not sure about the clutch simply because i don't know what "normal" is. On the OEM clutch I have it is damned near impossible to squeeze apart the pulley halves by hand. The outer pulley flexes a little, but not much opening. With channel locks it's still hard but can be opened. In operation the outer pulley moves in and out, seemingly smoothly, as wheel speed goes up/down (on the center stand). But I'm a bit afraid to actually ride the scooter now b/c the other belt popped so suddenly (and I don't yet have a backup). Is what I describe NORMAL for clutch stiffness?

If it has a stock main spring , then u should be able to squeeze it open by hand. When you squeeze it you have to sort of squeeze and turn the pulley to the left at the same time. I have a 2000 main and I can squeeze it in a good bit. When I say turn the pulley as u squeeze , the outer pulley " the one that moves " slightly spins to the left as it opens , so if you try to open it by pulling it straight back , it will be nearly impossible. So as you try to open it , slightly spin the outer pulley to the left.

When it comes to the gates belts , I always order them from here in the US .gates are made in China but they do have a section of the company here in the the US . you can actually go to Napa and buy the gates belt you need from them , that way you should be certain it is legit. I order my gates belts from eBay , out of a scooter company in Georgia. I have about 20 or so extra belts all the gates were ordered from them . one time they sent me a regular power link instead of a Kevlar , but they did end up sending me the right belt and let me keep the other one. The eBay name is " 678moped50" and the business cards they send say "moped motion " here are a few of my extra belts. Most are gates power link Kevlar pl30708 , but I do have a bando that came with my new engine a few yrs ago , a couple cheapo belts and a couple regular power link belts.  . |

Tried them but they have no Kevlar for a short case motor (like GY6).
Tried to turn my clutch and squeeze it, but the alarm was "on" and the FARKING air horns went off right into my ear. Totally deaf in one side now!
Anyway, I'm burned out on this stuff for the time being. After putting a new radiator, water pump (which required pulling the front section of the crankcase, since the pump goes on FROM THE INSIDE), thermostat, refilling all the fluids and starting it up I realized one of the head gaskets was blown (probably from when it overheated). Last 2 days pulling the heads on both sides, etc. Getting to HATE wrenches.
If this scooter belt breaks before the new ones arrive there will be a bonfire.

Thought I bought the Powerlink from ebay (usually GY6Racing), but my purchase history shows no belts so who knows where i got it. Oh well.

Back in 1999 I had a 1997 cavalier Z24 , I bought it with 23k miles on it and at 70k the water pump went bad. I had to unhook everything from the engine , unmount the engine and jack it up high enough so I could take the side panel off the engine "I obviously did not have an engine puller". the timing chain ran around the water pump . who ever designed them that way should have to wear an " I love Obama " shirt for the rest of their lives. But then again it was probably someone in his administration who designed them. |

That is funny!
Ordered a kevlar belt off your link. Thanks!
Yeah, I guess we all go through times when our machines have us beaten down ... this is just my time.
Rode the scooter 1/2 mile to the store to get a jug of ice cream. Have the cvt cover off so i can keep an eye on things. the idler gear of the kick starter is gone (never worked, so i removed it). As I pulled into the store I heard this weird noise coming from down/left. Stopped, looked down - the primary kick start lever had twisted and was rubbing against the clutch bell. Lucky the gear hadn't caught the belt, I guess. Anyway, so I ripped that out also.
Thought for a moment -- "maybe THAT is what caused the belt to pop!" ... but then i remembered 2 days ago when it popped I had the CVT cover on, not off.

When I received my new engine the kickstart was not smooth at all , so I removed the whole assembly and never had it back in since. Hope that belt works out good for u. |

GEH! You might be right (about the clutch causing the belt pop)! So yesterday the kickstart shaft was rubbing against the bell - yanked the thing off so that's no longer an issue. But it DID bring my attention to the clutch ... And this morning I noticed the thing is making a strange "bearing" noise. It's like a raspy bearing scrape while idling. I don't know if it's always been that way - maybe with the CVT cover on (it's off now) the noise isn't loud enough to hear). But maybe - maybe - there IS a bad bearing - the thing locked up a few nights ago after the really hard riding I was doing, and THAT caused the belt to pop. I'd take a video to get the noise but we all know such noises do not come out well in videos .. Well, maybe I will try ... View My Video |

I put your videon on loud on my surround sound, came out great, could hear most of it but the reason we lose audio in certain spectrums in online videos is because when we upload, the video sites recompress our videos and drop a lot of the data, not to mention the original recording process on most phones or cams already compress it, so you have to start with the highest setting on the recording device to get anything good. I think since sounds do play a part in diagnosing somtimes we should get a server to upload videos in the highest quality, or maybe upload to file sharing sites. Just my 2 cents on that. Your scoot sounds like my scoot but with a deeper sound coming from your muffler, I assume since your cylinder is bigger. I'm not saying that I know what the sound is, just saying that bearing noise you talk about I have too. But I haven't been popping any belts or anything like that. Lately I noticed my torque spring is getting worn out but that's it. |

Might have discovered the problem (not yet sure).
I used a mongrel variator assembly - Dr Pepper variator, but the GLIDE PLATE from the el Cheapo (it's got a larger diameter, so I thought the extra length would lead to more pressure against the variator and more top end.
I think the theory was correct (the thing was going faster Wed. evening than ever before). HOWEVER ~~~ the fingers of the glide plate were long enough to actually TOUCH the variator ramp! (the sliders were not large enough to keep it from hitting the ramp surface). When I took it apart Thurs am the sliders were all katty-whompus.
So I'm thinking -- maybe -- the variator got stuck in some open position with the sliders all askew, and this caused the belt to go nuts.
Anyway - I put the "OEM" glide plate back in and the 'weird clutch noise" is suddenly gone.
Maybe.
