I was very confused to find that there was no original washer in my scoot at all, so the whole time the outer pulley half was just up against the bushing.
I've never had a problem, never noticed anything. Not sure what to make of this. I've never opened it up before, and I've purchased this bike used from a gentleman who did all his own servicing. Did he lose the washer ? But if there was originally a washer there, I should see an imprint of sorts on the outer pulley, but no sign of it ever being there .
I've decided to just clean everything out and put it all back until I find out more.
