Help figure out ratios

Let's keep this simple. If you want the exact ratios, pull the side cover and count the teeth. Let me know how many teeth on 4th gear of the cluster, then 3rd, then 2nd, and finally 1st. Then count the teeth on the input (4th gear), then 3rd, then 2nd. and finally 1st. Let me know the numbers and I'll give you the exact ratios.

Another not so exact way to do it, is to mark the output shaft and input shaft. I would recommend a yoke in the rear with a clutch disc on the input and a Sharpie to mark the yoke and the disc. Shift the trans in 1st, turn the output shaft 10 revolutions and count the number of turn on the input. If the input turns (as an example) 26.5 turns, the ratio for 1st is 2.65 to 1. You can do the same for second and third. It won't matter in 4th because the teeth physically don't even have to be there, the trans input will be locked up to the output via the hub and slider, but you have to have the numbers to find the spur ratio for the rest of the gear ratios.

If I've got you and others all spun out, PM me and I'll give you my number, it's easy once you figure it out.

Also, the "books" aren't always right. They (sometimes) don't carry the decimal point out far enough to get the ratios exactly right.
