I just converted my Mav from the 8" rear to a 9" and from 3.00 to 3.70 i'm running a 26" or 26.5" tall tire, what gear teeth would i need to make my speedo accurate again? converter calculator? Thanks.
Just buy a $100 GPS. You will from then on have completely accurate speedometer. Maybe a TomTom ONE, or bottom of the line Garmin..... I will no longer deal with gears and such, but will use my portable GPS as a speedo in my mav.
http://www.gaugeguys.com/ratioadapt.htm whats cool is you can do 90 degree adapters (even in a 1:1 ratio) so if you are installing a different transmission you can use one of those instead of getting a longer cable (in some cases)
i like my speedos now... I have a Magellan, but it tells me to turn right when i'm on a mile long bridge.... let alone guage my speed... and yeah, thanks guys big help.
