Vespa V50 V90 Prim PK Gear Selector Four Speed

See additional picture below.

There are two different 4 speed gear gear selectors. The selection of the correct one is important to stop early wear on the selector and prevent premature slipping of the gears so we recommend that you check that the new selector matches your old one before fitting.
The gear selector can be checked if it is in perfect alignment with the gears in each of the 5 positions by holding the Output shaft upright in a vice with the selector and spring etc. in place, and fit the gears one at a time. Sometimes a small amount has to be shaved of the top of the selector to allow the 4th gear to fully engage. Over the years variations in manufacturers has caused slight differences in gearboxes and selectors so some slight alteration may have to be applied.
