| Can someone please explain how mixing variator roller (slider) weights will effect performance? Tim - masscoot wrote:
- 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 ![Wink](https://2img.net/i/fa/i/smiles/icon_wink.gif) |

| 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. |
