T-20 gear reduction

[dscheckman]

Hey, does anyone know the gear reduction a T-20 transmission provides. Discounting the clutch and torque converter. What I'm after is the gear ration of the rpm's into the transmission vs. rpms out. My machine is an older (mid 70's?) Max II with a JLO two stroke engine. Thanks for any help.

I think the driven pulley and the sprocket that drives the chain to the idler shaft are on the same shaft. If you want to know the ratio to a given point in the drive line mark both sprockets ar pulleys at 12 oclock and count the revs as you turn them.
