QuestionI am trying to find the engine serial number on my VT-500 so I can register it tomorrow
AnswerRobert, most of Honda's serial numbers are up on the left side, either on the top surfaces (front, side or rear on some shaft driven models), but some models have them stamped on a surface below the crankshaft area in a flat spot, more hidden.
You didn't give a year or model, so I am guessing that it is something like this:

Shadows should start with PC08E, the 83 VT500FT is PC07E and the 84 VT500FT has PC10E for the beginning of the number sequence.
