Generally 2mm over is the biggest piston available which would be 46.5. The extra .3mm = 0.011811 inches so I'd say your bore is just wallered out .010 or so past max. Sounds like replate or sleeve time
if I only had a pair, I could actually ride this thing

i mean it already has a sleeve in it so should i just bore it up to the 47mm piston?
