Scooterotica

Has anyone fitted these 2 together? I'm having an issue when I select 1st gear, the selector is pushing 5th gear up, as in the round bit protrudes higher than the notch on the layshaft where 5th gear rests. It seems like maybe the hole for the spring is machined in the wrong place.

I was advised by an engine builder, to stick with Af layshaft, and it’s cheaper.Put it up for sale , and it will cover the Af layshaft cost.And you get some money back. I did the same thing
