If from idle you open the throttle it should rev right up and SHOULD not loose any rpms, if it does your setup is wrong.
Your problem has nothing to do with your clutch and that already has been mentioned by Rockynv someone who knows how the cvt works.

Before I had a clutch get wet and rust a little and it created deep groves in the sheave and it would get stick there and not accel, just sound like its trying harder.

That would cause loose of top end the belt would not drop down any further whole different symptoms and results.

When my belt was startng higher in the variator , my rpms would rise until the clutch engaged fully , then my rpms would drop of some " because the belt was further down in the clutch and higher on the variator . " it's almost like starting in 2nd Gear . It didn't bother me to much because I still had decent takeoff . What type of mods do you have if any ? " I'm on the mobile version and can't see if you have any listed below . |

It could be a number of things , from the cvt to the scoot not being able to create power under load , which would be more of and engine prob not cvt . We just need a little more info . Also could be gear bearings or the rear axle bearings . Do you use sliders ? One or more could be out of place . Causing the variator to not open fully causing thee problem I mentioned with the belt riding higher .

Causing the variator to not open fully causing thee problem I mentioned with the belt riding higher . What happens if the belt is riding higher on the variator and lower in the clutch pulley is the clutch will engage at a slightly higher rpm due to the ratio of the cvt being harder to get going " like in second gear , and the rpms will raise a little higher then drop off after it fully engages and takes off . It will still begin to take off but after the clutch fully engages it will drop the rpms . Just like in a car it's easier to get it going it first then second or third gear . No need to post your mods I switched to the desktop mode and saw them. And I see you do use sliders . That's a sign of an out of place slider . That's where I'm at as of now . |

jjoshua20213 I think there could be a problem with the Variator. I would take it apart and clean it to make sure nothing is pushing it out. I have read before that with the belt shredding over time it fills out inside the variator pushing the belt out so it is, as some have mentioned, the belt is not seated down low but starting at a higher area on the variator which would give the symptoms you are describing. Let us know how you make out. Ital

When you take the variator off be careful , don't let the variator open as you remove it . This way when you lay it down " face down" and remove the rear sliding plate you can tell if one or more is out of place . I know the cvt better or just as good as most . You can't say it's not the cvt when signs point to the cvt .

Please tell me you don't use Koso sliders , I had nothing but problems with the Koso sliders flipping out of place . I've never had the dr pulley sliders do this but they can . Also any cheaper brand will also do this . Hopefully that's what it is " it's a simple fix "

jjoshua20213,
Let me ask one simple question, I assume you have the throttle Wide Open now when it drops the rpms and you keep the throttle Wide Open do the Rpms start to climb again or do they stay where they dropped to?

Alleyoop That's a good question , if it dosent pick up then it's not gonna be a cvt issue " probably fuel or other more concerning issue ." Unless your brakes are stuck engaged , probably not" lol , but if the rpms slowly rise then there is a good chance it's the cvt . |

That is correct, notice he has a A9 high rev cam and 8 gram weights which in my opinion are to heavy and to heavy of weights will cause the rpms to drop then pick up and may repeat, that is why I asked the question.
Maybe to help the troops out I should write up a topic of how a cvt works and what each part does and if one part is not working right what it will cause.

I agree with you " about the weights being to heavy but I guess it all depends on the variator also " and I'm curious why it just started happening in the past week .

Alleyoop They start to climb again. I'm going to go fully inspect the cvt now, but I doubt thats the problem. |
