I used the sliders. At first I went with heavier (23 vs OE 20.5). They lowered my rpm some with a slight decrease in acceleration. And when I used the infamous "Bando" belt, I was able to comfortably cruise at 70. But acceleration was barely tolerable. With the KYMCO belt and 20 g sliders , that got me to where I am. With the factory rollers, even 65 was touching the red zone.
But that's a moot point because I went on a 150 mile ride, stopped by a motorcycle shop, and ended up being "duped" (wink wink) into buying a leftover previously un sold 2013 Yamaha majesty. Which was HEAVILY discounted.
