OK, I see where you're coming from now.....you're also tuning for more bottom end on the PCX.sendler2112 wrote:Of course there are oversized rollers that will also increase gearing.

you can visually see they're taller at any point along the ramp.
Lowering the starting gear on a CVT is useful if your scoot is under powered (or if you're over weight?), but if you have enough torque when you pull out and have the HP to back it up, you can start off in a much higher gear and still get up to speed even faster.
The more power you make, the taller the gearing you can effectively run.
The Forza makes over 25HP and it doesn't need a lower starting gear.
In mixed weight tuning, you attempt to tune the total weight to shift the CVT as the acceleration curve reaches max torque and then tune the ratio of the 3sx3r weights to flatten the curve out and reach max HP just as the variator closes.
The 3 heavy sliders are used to alter the acceleration rpm curve due to the unique way sliders move up the ramp.
The 3 lighter rollers are used to maintain the original starting and final gearing of the variator.
