This is just a "satisfy my curiosity "type of question.I was reading JZFE's post and he mentioned his 13/52 gearing on his 06 fe450.My 05 fe550 had 15/48.I just changed it to 14/48 as it was too tall in the realy slow going stuff(it will almost idle along with no clutch now).Are the internal ratios that much different between the 550 and 450-or 05's and 06's?Thanks
