Old lady clutch pedal

Another possible solution you could look at would be to modify the z bar lengths to get the extra movement. May be an easier mod for some than the pedal, but should give similar results. It's all just about the ratios. Pedal pivot to linkage ratio, z bar pedal side to clutch sidea ratio, and clutch fork to fork pivot ratio. Some are easier to modify than others, but all should give the same overall results.
