Just want to mention what happens changing weights or springs or both.
With lighter weights your rpms need to rise to get the weights to push out the variator and make the belt move up to a higher ratio on the Variator. Lighter weights will keep your belt down in the lower ratio of the variator for more stronger take offs and getting up to speed quicker with higher rpms.
With stronger springs your rpms need to rise before the clutch pads get thrown out to grab the bell to turn the wheel. The difference is Because your rpms are now higher and turning the Variator faster causing the weights to push the variator out and down in your Clutch pulley and your belt now has moved up from the lower ratio of the variator and the scoot hasn't moved yet until the clutch pads get thrown out(big difference).
With the stronger Clutch springs if your motor is not very strong it will actually be sluggish getting up to speed because the belt is now ALREADY HIGHER in the variator and ALREADY DOWN in the clutch pulley. It is like a car with a clutch put the clutch in bring the rpms up and pop the clutch. IF the motor is not strong enough it will hesistate and or bog off the starting line because of the load on the motor trying to move the dead weight, until the rpms slowly climb higher.
So as you can see what each will do and what needs to be changed to get the type of performance you want or need out of your scoot.

what exactly makes them give you a higher top end?
i thought they just were for opening the plate sooner or later and i thought the plate was either open or closed allowing the belt to either sit at bottom for take off and the top for high speeds. but how could it make it go faster? will it allow the belt to sit higher than usual?

[replyingto=blacraven]blacraven[/replyingto]As Alleyoop said: This also means that heavier weights will push your variator out more allowing the belt to rise higher up. By default all dr. pulley sliders offer the same functionality because of the way they work they cause the belt to rise a bit higher. Here's a video of the variator in action: EDIT: Haha, you beat me to the video, Hank!  |

It is a trade off, you are looking for a DESCENT take off and getting up to speed and NOT LOOSE to much of your top end. Or you can go strong takeoffs and loose some top end or little sluggish on Take off and getting up to speed and max on your top end.
Your question what exactly makes them give you a higher top end?
You need two things:
1. get the belt to move as close to the edge of the Variator as possible.
a. To get the belt to move up as far as possible Heavier Weights will push the Variator out more BUT:
BUT: heavier weights ALSO lower your rpms, so what does that translate to:
a. belt is way up but your rpms are lower meaning the VARIATOR is not turning as fast= NO GAIN in top in or even loose TOP END.
That is why I said you have to give a little on one end and keep the other or Visa Versa or find a happy medium.
The CVT can only give you so much with the power of the motor. The only other thing you can do is put in taller tranny gears for more top end speed.

If you match your stock weights and replace them with dr. pulley slider weights there's potential that you could achieve speeds higher than you first achieved, while maintaining the same takeoff and acceleration, it'll just take tweaking and finding that perfect sweet spot.
with the right match of weights and springs you could very well have your cake and eat it too.

Update:
So yesterday it was raining so I didn't do much but attempt to drive home.
Everything was fine, no problem.
I took it for a test run today to see if it would do it again and lo and behold my belt broke.
I'm thinking it was that all along but I remember looking at it yesterday when i was fixing my kickstart, but I guess I didn't give a really close look.
I put on a back-up belt I had in the bike for emergency and I'm rolling again.
Also I checked the rollers and they look fine, one has a slight flat spot if you really look on an angle but I don't know if that's insignificant or not.
I don't know if this matters but last year when trying to get the variator plate off I destroyed the plastic fan blade looking thing, was this a fan to keep things cool in there? and if so, do they really work that much to matter? My belt was broke in the first place which is why I was trying to get it off.
