Low Ratio Conversion with Input Shaft

Whilst the top three ratios are close and well spaced for racing there is a high gap between 3rd and 4th gear, a particularly undesirable feature for racing.

Raising the first three gears to close the gap also closes all the ratios.

To give an overall reduction the same as the TZ250/350 the components supplied are a replacement input shaft and 1st output, both 2nd gears and 3rd output.
