This is an OEM Honda Phantom Vt750 engine. The manufacturer part number JH2RC5377FK500097 and the OE/OEM part number RC53E~ 2201687. Only 3300 miles. Had a slight ticking and had new clutch basket replaced by master mechanic but got tired of waiting for mechanic to have free time to work on the bike and just swapped a larger engine to get on the road before seeing if that was the issue and no longer need to work on this one.
