2018 Honda Ruckus. Stock except for an upgraded rear shock and upgraded to a Polini variator. Did a roller weight tune and found that 6g roller is the sweet spot for me. Off the line, WOT, rpms jump to 6500 then quickly to 7200rpm. They climb from there up to between 8200 and 8400 WOT on flats, peak of 8500rpm. Top speed is ~43mph. Hill performance has been pretty good (can maintain about 28mph up the hills I have on my commute), and it feels responsive when accelerating from a slower speed.
Decided to try sliders since I keep reading about how they can give you another little boost of performance. I had read you should increase the weight +1g when switching to sliders. Ordered a 7g and a 6g set. Both sets, in any combination were waaaaay too heavy. Acceleration and rpms off the line dropped (5300rpm and then very slowly climbed), and top speed dropped to 35mph (would reach 8K and maybe 8100). 6g was slightly better with slightly higher rpms, but the bike was more sluggish than it had been with stock rollers. Purchased a set of 5.5g sliders and while it's certainly better than 6g or 7g it's still worse than the 6g rollers. Off the line, the rpms will jump to 6800rpm, and then quickly to 7500rpm but the actual acceleration on the bike is fairly slow. WOT on flat, top speed is 38-39 with the rpms being 8400 to 8500rpm. Hill performance has dropped (25mph tops), and trying to accelerate from a lower speed is sluggish (even though the rpms jump up appropriately).
I marked the face of the variator with a permanent marker and the sliders aren't moving any farther outward on the face than I had with the rollers.
I know sliders can be installed incorrectly, so I've double and triple checked that they are in there correctly (flat spot against the back - where the boss slides through), angle headed downs toward the outer edge.
Any ideas on what I'm doing wrong? Should I go down to 5g sliders (if so, suggestions on how to remove the cores from sliders?)? Give up and go back to rollers?
I'm not expecting astronomical performance gains just by switching to sliders, but I expected them to perform as good as rollers, and maybe be a bit more efficient.
