Carb Riser Questions

Less rpms for same speed near top end??
A carb spacer can't possibly change the rpm to road speed ratio, that's fixed by the rear end gear ratio. So I'm now sure I understand what your talkin about there?
If you want more torque at the same speed than a stock engine has, you need to up compression ratio or more cubes or a supercharger or change to a bigger number rear gear. You see that a carb spacer ain't gonna get er done.

I skipped over that part as I assumed it has to be a perceived difference. As Martin states, RPM to MPH is a fixed ratio that is determined by gearing and tires and not by engine performance.
