Cheers for that

Searching the interent i can find the bleed washers no problem but as for the other 2 oil washers i can only find similar sized items, i take it it's not a problem to much if the washer size is slightely out on the OD? or if you know where to get them online with going to yamaha i'd appreciate it.

Also is the oil tray in the tool kit worth trying to get hold of? my bike didn't come with a tool kit so i don't have one.
