SHUDDERING AT SLOW SPEEDS By Alleyoop (Read 3,225 times)

Hi Alleyoop,
Thanks for responding.
Yea, I'll give some thought to trimming those down a bit.
What about the roller weights in my variator, could a lighter set of weights, or maybe a heavier set of weights increase the rpms, therefore the cintrifugal force, so that the clutch arms get thrown out harder?
I'm not exactly sure what effect the roller weights have on the operation of a Motor Scooter.
What happens when the roller weights are increased?
and...
What happens when the roller weights are decreased?
Please answer this question for me, so that I understand what's going on inside the variator.
If it's not to difficult that is.
If it will take you alot of explaining, then never mind.
I'll try and figure it out by looking it up somewhere else online

Thanks again!!!

Dan

Hi Dan,
Go read this thread I put this together a while back to try and explain the workings of the CVT and what each part does or does not do. It covers I believe everything in the CVT plus gearing as well. If you still have a concern or question do not hesistate to ask.

Hey Alleyoop,
I was also wondering...
I've read about other people who own Motor Scooter's talking about upgrading the variator, and the clutch.
As far as the variator goes, they talk about changing the roller weights, grams size and switching from rollers to sliders. Whats the best in your opinion
When they talk about upgrading the clutch, they talk about changing the main clutch spring.
What does changing the main spring do for you?

Thanks !!!

Alleyoop,
I wrote that last thread before I read your last one telling me to go and read the tread on the workings of a CVT.
After reading that thread, I understand how the CVT works much better.
Thanks again!!!

Great!! I tried to cover just about everything someone would ask. It is a lot and I got tired of keeping on typeing the same things over and over(HAHA).

I have a lot of stuff on my computer in email form and what I do is copy and past them on the forums to answer a question(HAHA).
