hello, long time since last comment here.

i have just change my speedometer on board for a km/h one. i used a GPS to verify the indicated speed and 130km/h is 130km/h on the GPS, so no safe gap with the allowed speed. i have 2% kilometer lost compare to GPS. i think i can change the speedo ratio to recover a "normal" speedo read. i wonder what are the pinion teeth number on a TH350 with 2.56 rear end. i have 27.03" rear wheels.

is my pinion green or light green on the gear shaft? i don't remember the color of the speedo cable in the tranny.



(the picture was taken many year ago when the tranny has been rebuilt)

thanks

If you are only out by 2 % don't worry.

what color is your driven gear? is it brown or purple. If it's brown, I would go purple.
