Yes, the Cota 123, 172, 200 242, 304 all have weak kick gears, as well
as the VA/VB 125. They did start heat treating the kickgears on the Cota
307, 309 and 310 models and they have held up well. I have customers that
are looking for kick gears, but when they hear the price of having these gears
made, they flee! The one good thing is that almost all of them use the same
gears with just the middle bearing being different in the later models.
