The
auto shift control is designed to shift an air shifter equipped bike at
a preset RPM. This RPM is set using MSD RPM modules. The unit is
calibrated for MSD equipped bikes but can also be used with a standard
Dyna S by using modules of 1/2 the value. Example: You want a 10,000 RPM
shift, so you would use a 5000 RPM module. The auto shift is easy to
install and comes complete with the control box, electric air valve, pro
push-button, handlebar on-off switch and complete instructions. The
complete system converts your old style air shifter into the electric
over air design. The control box may be purchased separately if you have
an
electric over air shifter. No RPM modules are included.
