Mixed Roller Weights in Variator

Can someone please explain how mixing variator roller (slider) weights will effect performance?

Ron,

I did not measure my RPM, but I agree on the smoothness. The the lag between 40-50 is eliminated and it is one smooth pull all the way through the throttle. The roller-chatter on take off is also gone. I have noticed a small reduction in RPM but having not measured it I can't be sure. My current MPG's have not been adversely affected, still in the mid to upper 50's (58 last tank). The first tankful after the slider install was affected and dropped to 51-52mpg due to many WOT's ...I mean testing!
I am happy with the results, next experiment is to mix two different weights (28g & 22g) alternating them in the slider slots. A friend did this and reports even better performance

It would seem to me that mixing the weights would cause accelerated wear on the heavier weight since they'd be doing most of the work at a given rpm. Not to mention possible warping of the variactor since the weights wouldn't be at the same distance from the hub at a given rpm. It might not be a real concern but something to think about.

The theory is to achieve a "middle weight" effect. If all you can get are 24s and 28s, and you want 26s, you'd try mixing them.

Don't know if it works or not.

Exavid you raise a good point, one I have not reasearched on my own. When I stated this point it was from a conversation I had with a fellow SWing rider. His info came from Matt at Scootertrap from a conversation about which sliders to install. I have not had a chance to talk with either since but plan on doing the "mix" myself in the spring (if spring comes this year). I know Matt visits sites like ours from time to time maybe he will chime in. The new material that DR Pulley is using is a real slick composite, Im not sure if there will be a wear or warping issue. That being said, it is still a cost effective upgrade to our SWings that increases the performance vs the JCosta roller pin swap-outs every 10K. Sadly, my SWing is tucked away in the frozen tundra that used to be my back yard. I hope to get to it during the first thaw when I inspect the belt and add some dry lube.
