How do I compute the change in speed when changing gears?
example, the V1 does 30mph at 5500rpm with 11 front and 52 rear (4.72 ratio)
new gearing is 11 front 42 rear (3.8 ratio), same engine.
now, i do suck at math...utterly fail at it most of the time. whats the simple non algebraic way to figure this?
