Hey Springer

What are the correct gear ratios for the '07 and '08 six speeds?  Thanks, Calvin.

They are the same as the 09's and the 06 Dyna.  They are all listed here ... http://www.bigboyzheadporting.com/Gearratio.htm

Just select the model year and it will list all the gear ratios, primary, secondary and overall ratios.  You can also change any pulley, sprocket or even swap out the whole transmission and see how it effects RPM or MPH etc.

Cool!  Thanks!  Later, Calvin.
