Thank You, Sir.Not quite. It only produces the lowest CVT ratio at launch. At low track speed, the CVT adjusts to the same ratio as it would with a looser belt deflection.
Absolutely right. Think about it. As soon as the secondary starts to open up, to upshift, the tip of that deflection set screw is contacting nothing but AIR.
It can have NO EFFECT on how the clutch action works until the engine goes below engagement rpm, and the secondary closes enough to hit the tip of the deflection set screw.
In ANY kind of a rolling start race... NO EFFECT.
The wrong width or length or cut angle of a drive belt ABSOLUTELY will affect performance somewhat thru the range of clutch action.
The belt deflection adjustment can help reduce that effect, AT LAUNCH and also before engagement rpm. ONLY.
