Mislabeled engine Taotao ATA250D

Being the curious guy that I am, I pulled the head on my 2007 Taotao AtA250D to get an accurate measurement of the cylinder. The engine is stamped as a 171FMM which would be 71mm bore, 250cc class. What I found is a standard 63.5mm bore and 62.2mm stroke which would make it the same as the common Lifan 163FML (200cc). Good to know for ordering parts.

My Rhino has a 167FMM (230) but the frame tag says it's a 150cc! I think that's probably how they snuck it past CARB! ;-)
