Have you tried the gear calculator in the DIY forum list?
No I haven't tried any gear ratio calc. All I know is my Jackshaft was twisting off axis because it is an extinct 1st Gen. SBP shifter that has since been replaced by a new version that is reinforced and attached to the engine mount.
The only reason I got it is because of the 203mm rear disk brake was in the way. What I really want is a 4G Grubee or a EZM QMatic. 4G's are nowhere to be found.
