Looks like an adjustment for something but I cant find any info. This is not my motor :brownseat: , just a pic I found. .
It's the shift cam stopper. (see parts 28-31)

Ok , Thanks - So it isnt adjustable, just gets screwed in tight?
correct. there should be a spring and a metal cap inside of it, so if you take it out, watch out for that.
