does anyone know how to calculate axle ratio by the amount of times the tire turns, amount of times the pinion turns, and the tire diameter? i have an axle for my go cart with 2 speeds, so im wondering how it will do with a 500 cc bombarider

yep .....if the wheels turn 3 times and the pinion 1 you have a 3.00 to 1. if you have 3and 3/4 turns of the wheels to 1 pinion turn you have 3.75 to 1 gears.





If I had a vagina it would be as big as a garbage can..

ok
its extremely difficult to dtermine close ratios ie. 5:13....5:29 etc but roughly lift one wheel (if its open) put a mark on the pinion yoke or drive shaft......turn the wheel 1 full turn....divide by 2....this will tell you roughly.......or....remove the diff cover and on the ring gear there is usually marked the tooth count.....10/41 or whatever this would be 4:10's.....number of ring gear teeth divided by pinion teeth.
Hope that help.....Pete

1 full turn.....count the revolutions of the pinion or yoke....divide.................................... .................see above

if it has a differential and you lock one side, the other tire will spin twice as quick. PUll off the cover and count the teath on the crown and pinion gear. divide the driven bye the drive to calculate the ratio.

whats this axle out of?
