That would be nice Don, but I can't afford that.

I know that feeling. That's why I haven't finished mine. Seems like there's always other priorities.

The difference between 3.25 and 3.50 gears would be less than 200 RPMs at 60 mph if the tires were the same size before and after the change.

You can use the spreadsheet here to play around with tire sizes and gear ratios

And, if you still need to change your speedometer gear to correct your speedometer you can use this spreadsheet

Hey Don, I don't have the office program to open the xls spreadsheet. Is there a different way for me to figure out the speedometer gear I need?
