Doing some trans tuning on one of my scoots and I seem to have a fairly large discrepancy between weight with some rollers. So, is there anything wrong with using say 5gr rollers and 15gr rollers (just as an example) to come up with 10gr? Or do you guys try to keep a closer spread between the weights you’re using to obtain an average.

They need to be the same weight or it will be unbalanced. If needed you can alternate them using 3 each of two different weights to obtain a different total weight. 5g-6g-5g-6g-5g-6g a small scale is useful in matching the weights to each other.

Yeah, I’m aware that everything has to be balanced. I don’t think I’m describing my question well enough... is there any reason that using a 15gr-5gr-15gr-5gr-15gr-5gr to come up with 10grams is any better or worse than using a 9gr-11gr-9gr-11gr-9gr-11gr combination to come up with 10gr. Does the amount of difference between the two weights you’re using to achieve an average matter?
Edit: grammar/clarity

I've run 3 heavy weights to figure out what I wanted then switched to 6 of half that, so same total in the end, and noticed no difference.
I think having them unbalanced would cause the ramps to wear unevenly.

Okay cool. I’m going to be using some rather heavy weights with some pretty light ones to average around 5gr and wanna make sure that when I order sliders for whatever weight I settle on that I’m not going to be surprised with a major difference because of the big discrepancy between the weights I used to get an average weight.

There is a slight difference between the behavior of sliders and rollers though...

So I hear... from what I understand though, sliders are just a little smoother and different than rollers, but the weight I buy for a sliders should be the same as I would buy for a roller. I've heard some people go up or down a half or whole gram too. This will be my first experience with slider; when I'm finally happy with my CVT tune and purchase them for this scoot. |

I don't think you should have more than 1 gram difference between the mixed rollers. 15 and 5 is a drastic difference, the heavier of the 2 weights will be doing all the work. sliders Slide and rollers Roll, I'm pretty sure sliders have to overcome friction and therefore you would have to go a little heavier versus rollers. |

I have several tuning sets, I'm just short on weights in the 4-8gr range. I'm not actually using 5 and 15gr to make 10gr, that was just to help illustrate my question. I may be doing something like using 4 and 8gr weights to make 6gr.
That's what I figured about sliders as well, but the most reliable sources I can find say buy whichever weight sliders you would normally use for rollers. I've also heard that you should buy lighter rollers than sliders and I've heard buy heavier sliders than rollers, so it's confusing haha. Anyone have any real world experience?

Back in TotalRuckus.com days <sigh> we used the same weight of sliders as rollers...
(but that's a 4-stroke. I don't know if 2T or 4T makes a difference)

It varies. I have tuned some CVTs where sliders and rollers act alike. Other times the sliders need to be heavier. I don't recall needing lighter sliders to get similar results as rollers. Most likely it's the design of some variators.
