thx i realize the bearing is two parts a washer and bearing listed as one in diagram. so think its right. i did have it slip off the spacer before maybe it did it again. im gonna have to check.

im working on a xs650 clutch too but thank god its doing ok. they are a little different in where the bearing goes.

the mx250 clutch looks like a dt1 250 one in washer sequence

got clutch to work right after removing this gear to the left of clutch that tied into basket gear. for some reason the gear seems a little wobbly like it needs a different washer or extra washer on back to help clear the race bearing. anyone know what washer goes behind this or if theres three washers total? thx

got a kick diagram finnaly. looks like gear is 29 and im missing a 28 washer.  it s wave washer 2 dollars plus shipping n tax.  

Those gears do get floppy & wear as they sit on the shaft but missing a washer or not isn't going to affect the clutch operation. Unless i'm missing the point of what you're saying sorry.
