How's it going . everyone knows I ordered 3 koso variators in the past yr. But after I ordered the second one I also replaced the clutch pads in my ncy clutch assembly and I installed a new 2000 main spring. Somehow I ended up installing the new pads and 2000 main in one of my stock clutch Assembly's . I had them both tore apart and in my scooter parts box. This could be the reason I am not getting full climb on the variator like I was before. If anyone else has a 3rd gen ncy clutch assembly , it has 2 settings that you can set the clutch to which allows the puppy to open different. One of the settings is suppose to be just like the stock clutch , but it actually allows the pulley to open further , somewhere between 1-2 mm further. That is a good bit when it comes to belt climb . I just put it back in and I will post the results. The stock slots on the ncy are cut closer to the. Seals on both ends and are a littler longer . this also means it may close a little further also. I'll post a pic of the stock clutch . I still have it tore apart and show everyone what I'm talking about. I should have taken pics of the ncy but I didn't and I'm not tearing it apart again ,lol. TBA I think I posted about this back in the scoot dawg days . I wonder if someone can find it?
Prob not until 2moro.

Here is the stock clutch . look at the end of the slot ,towards the pulley side . there is a seal right after the slot on both sides. On the ncy clutch you can barely see any metal at all . the slot on the ncy now that I look at the stock again. Is between 1-1.5 mm longer close to 1mm on the pulley side and close to .5mm on the open side. So the pulley would open about 1mm further and close about .5mm further.  |

I know it looks as if there is not much room to work with , but on the ncy I actually had to make sure the slot wasn't cut into the seal , that's how close it is.

Hey jersey , you have the same clutch assembly , but if I'm not mistaken it is not installed yet . not sure if you want to or not , but if you remove the clutch pads and spring , and pull the cap off you can see if yours is the same way. If you don't want to , maybe you can mark the variator and see if the belt climbs higher with the ncy clutch assembly .

Pic of belt climb after ncy assembly back in .  . Took if for a short ride , but if u look close you can see the slight shaded black from the belt . I drew the mark with a sharpie after the run , it looks like I colored too much , you can see to the right of the mark the shaded black belt mark . the more noticeable whitish mark is from before. |

Still trying to understand how the clutch works (not the pads; the pully assembly). So if I understand, the slots your pictured have a pin sticking into them. To slide the pin along the slot (and open the drive faces of the pulley) the main spring has to be compressed. Is that right? If so, what force is it that pushes the pin along the slot and compresses the main spring? Just the tension of the belt forcing the drive faces apart? |

The only difference being you re-assembled the ncy clutch in the non-OEM position? ps: I zoomed your variator photo and think you are on crack cocaine if you think there is some difference! |

I'll put them side by side , I drew them both on , so I'll have to go by the belt marks. I trust your judgment, but I better check. |

It looks to me as if there is a slightly higher belt climb on the first pic . each has a slight shade above the more pronounced marking but it looks slightly higher . I'll have to run her for a few more miles then check again .

Can you zoom the photo to make it the same size for me ?

. Look to the left of the black mark on both pics , the top one looks like there is less room . the flash from the camera really hides the belt mark to the left on the top pick . |
