Yamaha RD350 YPVS Close Ratio Conversion with 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.  These kits were first made by at Nova back in 1984.

These are now also supplied with new 1st and 2nd gear bushes.
