What size mirrors fit this thing? i didn't even think about the ruckus mirrors not fitting this thing. i was going to ride the vino to work this morning and realized i didn't have any mirrors on it so i tried mirror from my ruckus, kymco, and even ones from a spree and they were all too small.

Yamaha uses both thread directions so only one of your honda mirrors would have worked. I'll check sizes in a bit but 12mm comes to mind.
