I’ve taken off the gear cover on Yamaha slider 2000 a concave washer fell out and I can’t work out where it goes the smaller one was on the drive as per picture but I’m not sure if the bigger one goes on the rod that fits between the cogs
Maybe this can help you to sort it out. Btw, press the button"parts diagram" That gives you an exploded view of the whole shobang https://www.motorcyclespareparts.eu/en/yamaha-parts/2005-ew50-slider-scooters/transmission
