Default Gear Ratio???

I have bravo XR's that we just pulled apart. The lower gears have 15 and 17 teeth. What gear ratio is this? We couldn't find it in the books we had.

With the upper gear set count of 16 on the pinion and 19 on the upper/lower gears, a 15 pinion and 17 driven gear in the lower would be 134.6 or 1.35:1.Sould be a "R" stamped on the splined yoke.
